Despite staking being one of the most used DeFi strategies, the process of unstaking, can become a cumbersome activity with lengthy locking periods. Tackling this inefficiency, Ankr released a flash unstake feature for BNB liquid-staked tokens back in February and is now expanding it to Ethereum, updating both unstaking mechanics.

## TL;DR:
- Unstaking periods are a cumbersome feature of the most popular DeFi strategy.
- Flash unstake enables users to have instant liquidity for their LSTs, thus optimizing their capital efficiency. 
- After successfully introducing the feature to ankrBNB, Ankr is now expanding its offering to Ethereum LST users’.
- Ankr flash unstake v2 will introduce dynamic fees, which may enable lower fees.

## Unstaking Constraints

Leveraged on the widespread implementation of proof-of-staking networks, [staking](https://www.ankr.com/staking/stake/) has become a leading DeFi strategy, enabling users to compound rewards on their tokens. On the back of it, [liquid staking](https://www.ankr.com/blog/liquid-staking-a-comprehensive-guide/) - enables users to stake tokens, and in exchange mint a wrapped token that encompasses the underlying asset and the staking rewards - is a strategy that has captured a lot of users’ attention, allowing them to stay liquid while earning rewards from their stake. 

However, regardless of the staking strategy the user opts for, when they try to unstake, they have to face a lock period that can go up to 30 days. This is highly inefficient, since the tokens are not accruing any additional yield, and can’t be used on any different DeFi endeavor.

These lock periods are in place to prevent malicious activities toward the network, thus maintaining network security and promoting a healthier staking environment. Nevertheless, they also encompass a huge opportunity cost for the final user.

## Flash Unstake: onboarding Ethereum, the largest DeFi blockchain

Understanding the constraint and the inefficiency that the unbounding periods present for the users, earlier this year, Ankr introduced a [Flash Unstaking](https://www.ankr.com/docs/staking-for-developers/flash-unstake/bnb-flash-unstake/) feature for the ankrBNB LST. We are now happy to announce that upon the success we’ve seen on that feature, we are expanding it to ETH and ankrETH. Implementing this new feature for ankrETH will significantly reduce the unstaking time for users, with the unstaked ETH being sent on the same transaction.

But changes don’t end here. When Ankr first released the flash unstaking feature for the ankrBNB token, a fixed technical service fee of 0.5% was [proposed](https://www.ankr.com/blog/Tradicional-vs-Flash-Unstaking/). However, with the release of the ankrETH Flash Unstaking feature, these fees will change from a fixed to a dynamic structure.

The new framework, to be implemented for both BNB and ETH solutions, will base fees on the tokens' balance, creating a more responsive solution for its users. Thus, the fee will be adjustable depending on the amount of available ETH/BNB. As the availability increases, the fee decreases, and vice versa. 

This structure aims to maintain the pool's health and competitiveness, offering an advantage over typical DEX swap fees and slippage. Furthermore, by introducing a dynamic fee, Ankr will be able to, under certain conditions, lower the previously proposed fixed fee.

To ensure Flash Unstake sustainability, Ankr's strategy involves in reserving 5% of the total staked tokens in their original form. Therefore, whenever a user tries to Flash Unstake, they withdraw from that 5% pool. 

The updated version reveals that only half of that value (2.5% of the total staked tokens) is needed to maintain the current fee structure. Consequently, this implies that every time the reserve approaches 50% of the intended target, users will benefit from a lower service fee.

*Framework of Ankr Flash Unstake - v1 vs v2.*

## Flash Unstaking: Improving LSTs liquidity

Ankr’s flash unstaking feature significantly enhances the liquidity of ETH LSTs and eliminates one of the largest staking barriers. This is only possible since Ankr provides liquid staking services that enable the immediate exchange between tokens.

Furthermore, one may think that by having an LST token, it would already be able to use it on any other DeFi endeavor. Even though LSTs open many doors in terms of capital efficiency, this ain’t completely true. LSTs, being tokens created by third parties, don't offer the same utility as the original asset, since they can't be used for certain functions like paying gas fees, and not every platform accepts them.

By facilitating the exchange of LSTs for the original asset in a seamless manner, flash unstaking ensures that users can instantly receive the original asset back in their wallets, unlocking the full potential of the held tokens and reducing the necessity of deep liquidity on Liquidity Pools. 

This immediate conversion process is a key advantage, distinguishing it from traditional staking mechanisms that typically involve lengthy lock periods. On top of this, depending on the token balance, at the swap time, transactions may be cheaper and with less slippage than swapping on a DEX.

Furthermore, flash unstaking empowers users with unparalleled flexibility in their DeFi activities. Since this process allows for instant staking and unstaking, users can swiftly shift their strategies and capital in response to the evolving DeFi landscape. 

In such a fast-paced ecosystem, agility can make the difference between being early or late to new opportunities. The ability to quickly adapt and move assets around leads to more effective capital management and potential leveraging of new opportunities.

December 18th marks a pivotal day for ankrETH users, as they gain the opportunity to restake their tokens within the EigenLayer framework. Restaking caps for Liquid Staking Tokens (LSTs) will also be expanded to 500k, thus enabling the restake of the newly integrated LSTs, where ankrETH is included.

## TL;DR:
- On the 18th of December, ankrETH users will be able to restake their tokens with EigenLayer.
- LST restaking caps will be increased to 500k allowing new integrated LSTs to bring liquidity to the middleware framework.
- Ankr urges its users to be ready on the 18th of December so they can leverage this capped opportunity.

## AnkrETH's Integration into the EigenLayer Ecosystem

[Ankr](https://www.ankr.com/) is thrilled to finally see the opportunity to become an integral member of the [EigenLayer](https://www.eigenlayer.xyz/) framework coming to life. After being one of the [most-voted](https://x.com/eigenlayer/status/1722618501519876390?s=20) protocols to be integrated into the new Ethereum middleware, back in November, we are now getting closer to the day that ankrETH users will be able to restake our LST with the middleware and unlock a second layer of yield for their tokens.

EigenLayer, a middleware protocol built atop Ethereum, introduces the concept of 'restaking’, which will enable the reuse of staked ETH or LSTs like ankrETH to secure a set of smart contracts that will expand Ethereum’s trust network. 

From Ankr's perspective, the integration into this ecosystem is a major opportunity to expand our services within Ethereum's DeFi services, enabling Ankr users to leverage one of the leading frameworks currently being developed within Ethereum.

As it was previously noted, Ankr will have a dual role in this ecosystem, acting both as an [operator](https://www.ankr.com/blog/unlocking-eth-2nd-yield-layer-ankr-will-become-an-eigen-layer-node-operator/) and an [integrated LST](https://www.ankr.com/blog/ankr-eth-joins-the-eigen-layer-ecosystem-as-a-collateral-asset/?page=1). Leveraging this dual role, Ankr will be able to provide restaking services for its users, as well as create another use case for our liquid-staked token.

## ankrETH Integration within the EigenLayer ecosystem

The integration of ankrETH as a collateral asset on EigenLayer brings several advantages to Ankr users. This move will extend the utility of ankrETH tokens, allowing our liquid stakers to leverage from a second layer of yield while also becoming an integral part of the blockchain expansion. Thus, we forecast a demand increase for our liquid staking solution.

According to EigenLayer’s recent [announcement](https://www.blog.eigenlayer.xyz/adding-lsts-to-eigenlayer-raising-the-caps/), ankrETH holders will be able to restake their LSTs from the 18th of December, at 10 am Pacific Time (PT). With the integration of the new tokens, the LSTs' restake cap will also [increase](https://x.com/eigenlayer/status/1732477834638278999?s=20) to 500k, allowing the restake of any of the newly integrated LSTs, where ankrETH is included.

Ankr is anticipating a surge in its LST adoption and an expansion in the scope of investment strategies for Ankr users. This collaboration will enrich our DeFi compound opportunities, providing another solution and opening doors to new possibilities in Ethereum's network development.

## Final remarks

Aligning with Ankr’s ethos, this new integration will create yet another use case for the ankrETH token. “*We are very satisfied to have ankrETH to be part of Eigen Layer. This will further create amazing use cases for Liquid Staking while further help securing the Ethereum Network and all the applications build on top of Eigen Layer. The potential is huge and Ankr is proud to continue to be a core web3 infra provider in the space*. ” states Tiago Pratas, Ankr DeFi lead.

As we prepare to embrace EigenLayer restaking opportunities on December 18th, we would like to encourage our current user base to liquid stake with our platform and urge you to be ready to seize the opportunity to be part of this development in Ethereum's decentralized trust marketplace.

AnkrETH on EigenLayer: A New Era for Liquid Staking Tokens

![rpc node.jpg](https://s3-frontend-strapi.s3.us-west-1.amazonaws.com/rpc_node_a4828fc7d2.jpg)

When diving into the world of blockchain development, you’ll soon come across a variety of terms and acronyms that can get confusing! Let’s tackle one of the most common terms you may come across on your builder journey: RPC.

## What are Remote Procedure Calls (RPCs)?

An RPC could be classified as a type of [API](https://www.redhat.com/en/topics/api/what-are-application-programming-interfaces) (application programming interface) that allows for developers to run code that can be executed on servers remotely. And when developers build dApps with RPC capabilities, the app will be able to connect users’ requests to information from blockchains. For instance, when users access a DEX or use MetaMask to make transactions, their requests go through an RPC to connect them with the nodes that hold the data from blockchains.

Remote Procedure Calls (RPCs) can be thought of as the secret handshake of distributed systems. It's a protocol that allows a program to cause a procedure to execute in another address space (commonly on another machine).

Picture this: you have Program A on Machine X, and Program B on Machine Y. Now, Program A wants to execute a function that's in Program B. RPC is the messenger that lets A make the call and get the results, almost like A is whispering instructions to B through the digital grapevine.

The cool thing is, from A's perspective, it's just invoking a local procedure, even though the heavy lifting is happening somewhere else. It's like outsourcing tasks in the programming world, but with a fancy communication protocol. It's crucial for building distributed systems where different parts of a program can live on different devices but still need to work harmoniously.

## What is an RPC Node?

In the intricate realm of blockchain technology, an RPC Node (AKA a blockchain Full Node) serves as the linchpin that facilitates communication within a decentralized network. Let's break down its pivotal role:

- **Digital Postman:** Think of the RPC Node as a digital postman, ensuring messages and requests flow seamlessly between different elements of a blockchain system.

- **Transaction and Smart Contract Facilitator:** When a user initiates a transaction or engages with a smart contract, the RPC Node steps in, allowing these actions to be carried out across the blockchain.

- **Behind-the-Scenes Conductor:** It's essentially the behind-the-scenes conductor orchestrating a symphony of decentralized interactions, ensuring that the diverse components of a blockchain work harmoniously.

Beyond its role as a communication facilitator, an RPC Node acts as a catalyst for efficiency in blockchain operations:

- **Speed and Reliability:** The RPC Node optimizes the execution of transactions, ensuring they happen swiftly and reliably.

- **Developer Interface:** Developers often interface with RPC Nodes to query data, enabling the smooth functioning of decentralized applications.

In essence, an RPC Node emerges as the unsung hero in the blockchain landscape, quietly empowering the decentralized ecosystem with efficiency, responsiveness, and seamless communication.

## How RPC Nodes Work

In the intricate dance of blockchain technology, RPC Nodes, short for Remote Procedure Call Nodes, function as silent architects, ensuring the smooth flow of communication and transactions within decentralized networks. Let's unveil the mechanics of how these nodes work:

- **Communication Backbone:**
    - RPC Nodes serve as the backbone of communication within decentralized networks.
    - They facilitate the exchange of information between various components of a blockchain system.

- **Transaction Execution:**
    - When a user initiates a transaction or engages with a smart contract, the RPC Node intervenes to execute these actions across the blockchain.
- **Digital Facilitators:**
    - Analogous to digital facilitators, RPC Nodes act like intermediaries, ensuring messages and requests travel seamlessly across the blockchain.

- **Decentralized Orchestra Conductors:**
    - RPC Nodes act as behind-the-scenes conductors, orchestrating decentralized interactions to guarantee the harmonious operation of different blockchain elements.

- **Optimizing Speed and Reliability:**
    - Beyond communication, RPC Nodes optimize the speed and reliability of blockchain operations.
    - They streamline the execution of transactions, ensuring rapid and dependable outcomes.

- **Developer Interaction Hub:**
    - Developers interface with RPC Nodes to query data, contributing to the smooth functionality of decentralized applications.

### How RPC nodes enable communication between clients and blockchain networks

RPC nodes serve as the vital intermediaries that bridge the gap between clients—be it users or applications—and the expansive realm of blockchain networks.

- **Communication Conduit:**
    - RPC nodes act as the communication conduit, allowing clients to send requests and receive responses from the blockchain network.

- **Protocol Interpreter:**
    - They interpret and implement the Remote Procedure Call (RPC) protocol, which serves as the language for communication between clients and the blockchain.

- **Transaction Relay:**
    - When a client initiates a transaction or requests data, the RPC node efficiently relays these requests to the blockchain, ensuring seamless interaction.

- **Response Delivery:**
    - RPC nodes play a pivotal role in delivering the responses generated by the blockchain back to the clients, completing the communication loop.

## What Are RPC Endpoints?

An RPC endpoint is a specific URL that acts as the entry point for interacting with a particular resource or function of a Remote Procedure Call. It serves as the communication channel between an RPC client (e.g., a web application or mobile app) and the RPC node.

When an RPC client sends a request to an endpoint, it specifies the desired operation and any necessary data. The RPC node then processes the request, retrieves the requested information, or performs the requested action, and sends back a response to the client.

In other words, an RPC endpoint serves as the designated access point where Remote Procedure Calls (RPCs) are initiated and processed. Think of it as the digital front door to a decentralized network, providing a specific address where clients can communicate and interact with the blockchain. This endpoint acts as a crucial interface, enabling a standardized method for clients to send requests and receive responses, fostering seamless communication within the complex landscape of distributed systems. Essentially, it's the linchpin that facilitates the language of RPCs, ensuring a streamlined and efficient exchange of information in the crypto ecosystem.

## Different types of RPC endpoints

The diversity of RPC (Remote Procedure Call) endpoints within the blockchain space is a testament to the adaptability of this technology across various use cases. While the specific categorization may vary based on factors such as network architecture and blockchain protocols, we can broadly identify several types of RPC endpoints:

### Basic RPC Endpoints

Basic RPC endpoints function as fundamental access points within a blockchain network, providing a simplified interface for users and applications to communicate with the underlying decentralized infrastructure. These endpoints enable Remote Procedure Calls (RPC), allowing external entities to query essential blockchain data, submit transactions, and retrieve critical network information. Serving as the foundational building blocks of interaction, basic RPC endpoints play a pivotal role in facilitating seamless communication, making blockchain functionalities accessible and manageable for users and developers alike. Their simplicity and versatility make them essential components for initiating transactions, retrieving information, and monitoring the overall state of the blockchain network.

### Advanced RPC Endpoints

Advanced RPC endpoints represent a more sophisticated layer within a blockchain network, offering specialized functionalities beyond basic operations. These endpoints provide advanced features tailored to specific use cases, such as interacting with smart contracts, managing complex consensus mechanisms, or accessing advanced analytics and monitoring tools. Unlike basic RPC endpoints, their scope extends to intricate aspects of blockchain technology, catering to the needs of developers, administrators, and applications requiring nuanced control and insight. Advanced RPC endpoints contribute to the extensibility and adaptability of a blockchain network, empowering users with advanced tools to navigate and harness the full potential of decentralized systems.

### Public RPC Endpoints

Public RPC endpoints serve as externally accessible gateways to a blockchain network, providing a means for developers, applications, and external entities to interact with the blockchain's functionalities. These endpoints are openly available, enabling broader participation and integration with the decentralized ecosystem. Public RPC endpoints typically offer essential operations like querying blockchain data, submitting transactions, and accessing network information, fostering a more inclusive environment for developers and applications to engage with the blockchain. This openness facilitates the seamless integration of decentralized applications (DApps) and encourages the broader development community to leverage the blockchain's capabilities, fostering innovation and collaboration in the public blockchain space.

### Private RPC Endpoints

Private RPC endpoints are access points within a blockchain network that are restricted and accessible only to specific participants or entities with authorized permissions. In contrast to public RPC endpoints, which are openly available, private RPC endpoints are designed to maintain a controlled and secure environment within permissioned or consortium blockchains. These endpoints typically cater to participants who have specific roles or privileges within the network, allowing them to interact with the blockchain's functionalities according to predefined access levels. Private RPC endpoints play a crucial role in safeguarding sensitive information, ensuring that only authorized entities can execute transactions, query data, or perform other operations within the confined scope of a private blockchain network.

### Custom RPC Endpoints

Custom RPC endpoints are tailored access points within a blockchain network designed to address unique functionalities or specific use cases that go beyond the standard operations offered by basic RPC interfaces. These endpoints are crafted to accommodate specialized requirements, providing a means for developers and administrators to implement custom features, consensus mechanisms, or protocol extensions. Custom RPC endpoints contribute to the adaptability of a blockchain system, allowing it to be fine-tuned to suit the distinct needs of a particular network or application. These endpoints empower blockchain architects to implement and experiment with novel functionalities, enhancing the overall flexibility and customization potential of the decentralized ecosystem.

Fluent is a unique layer 2 rollup that lets you build scalable applications in your favorite programming languages. This opens the floodgates for non-web3 companies to join the space without training engineers in Solidity or making expensive hires while using existing design patterns and packages.

#### **The key components of Fluent:**

**ZK Rollup**

Fluent leverages ZK rollup technology to relieve performance and cost constraints, enabling developers to build high-throughput applications while retaining the security properties of Ethereum.

**Wasm Execution**

Fluent uses a WebAssembly (Wasm) virtual machine to significantly lower the learning curve for developers. Wasm allows developers to build applications in general-purpose programming languages like Rust, TypeScript, C/C++, Go, and more.

**EVM Tooling Compatibility**

Fluent maintains compatibility with Ethereum Virtual Machine (EVM) standards, allowing developers to execute and interact with Solidity smart contracts, use tools like MetaMask, and take advantage of EVM innovations. The result is minimal friction for EVM ecosystem users.

#### **Essential benefits for developers using Fluent:**

- **Simple:** Use programming languages you already love - Rust, Typescript, Go, C, or any language that compiles to WebAssembly.
- **Scalable:** ZK rollups enable high throughput and low-cost apps while retaining the security properties of Ethereum.
- **Compatible:** EVM extensions enable compatibility with Solidity smart contracts and tools like MetaMask.
- **Flexible:** Leverage the best module for each function in the rollup stack.

## What Are Ankr’s New Fluent RPC Connections?

- Ankr’s Fluent RPCs (Remote Procedure Calls) connect your wallet, command-line interface, or dApp with the Fluent layer 2. They act as a messenger or blockchain router that relays on-chain information between Fluent nodes, dApps, and ultimately end-users so they can execute necessary tasks like transactions, populate wallet balances, fetch ownership information, and much more.

- Fluent RPC endpoints are a gateway for developers to interface directly with Fluent Network — a portal to communicate easily, remotely, and with no need to go through the DevOps of establishing their own Fluent nodes.

- Ankr is providing a geo-distributed Fluent RPC comprised of blockchain nodes running worldwide for incredibly low-latency and reliable connections.

## How Do the Fluent RPCs Help Developers?

Building with Fluent is an excellent choice to create interoperable and scalable dApps but requires access to the information on Fluent nodes to do so. Therefore, Ankr’s RPC solves the following developer troubles:

 **Eliminates complex node ops** - Ankr’s Fluent RPCs will completely remove the need for many developers to set up their own Fluent nodes, removing hours of time spent building, calibrating, and fixing node issues.

**Grants access to advanced tools -**  Ankr’s [Premium RPC Plan](https://www.ankr.com/rpc/pricing/) instantly grants access to the best tools to build applications quickly, including:

- At least 1,500 Fluent req/sec
- Dedicated Fluent endpoints
- Prioritized requests
- WebSockets (WS) capabilities

**Powers apps and open-source software that need access to Fluent** - Connect with a cluster of high-performance nodes that holds the information you need to build and operate dApps with Fluent chain capabilities.

**Supports the Fluent network**Ankr will strengthen the Fluent network globally by offering easier development and a broader, decentralized node infrastructure.

## How to Make Your First Call to Fluent

You will soon see Fluent as a supported option on [Ankr’s RPC Service](https://www.ankr.com/rpc/) to make your first call! You can use the provided endpoint to call the Fluent chain using the standard EVM JSON RPC methods.
