What is EigenDA Restaking?

EigenDA is a data availability solution with 10 MiB/s of write throughput and the lowest cost in its class. The system's design is inspired by Danksharding, which promises to scale Ethereum's DA beyond EIP-4844.

What is an AVS?

AVSs are components of the EigenLayer protocol. AVSs are designed to enhance the rate and scope of open innovation by leveraging EigenLayer smart contracts to borrow programmable trust from the Ethereum network. An AVS is any system that requires its own distributed validation semantics for verification, such as sidechains, data availability layers, new virtual machines, keeper networks, oracle networks, bridges, threshold cryptography schemes, and trusted execution environments.

What is restaking?

Restaking is a mechanism that reuses the locked economic security of Ethereum to enhance the security of smaller networks and applications. Restaking allows validators to opt in by assigning their credentials to smart contracts on the Ethereum blockchain, thereby earning additional revenue for securing chosen modules. This process broadens the range of blockchain applications that can benefit from pooled security, as validators validate various modules including consensus protocols, data availability layers, virtual machines, and bridges.

There are two types of restaking, native restaking where participation requires running an Ethereum validator node and changing withdrawal credentials to EigenLayer's smart contracts, and liquid restaking where users can deposit liquid staking tokens and delegate assets to a particular Operator. Restaking streamlines the bootstrapping security process for new applications, making it more cost-effective, efficient, and scalable.

What are the Operators and their role in AVS?

Operators, who can be individuals or organizations, play an active role in the EigenLayer protocol. By registering within EigenLayer, ETH stakers can delegate their staked assets, whether native ETH or LSTs. The Operators then opt-in to provide a variety of services to AVSs, enhancing the overall security and networks’ functionality.

What is EigenDA?

EigenDA is a decentralized data availability service, leveraging the EigenLayer restaking mechanism. As the inaugural AVS on EigenLayer, EigenDA enables users to delegate stake to node operators responsible for validation tasks. In return, these operators are rewarded with service payments. Rollups, including zero-knowledge and optimistic rollups, can harness EigenDA by submitting data, unlocking advantages such as reduced transaction costs, increased transaction throughput, and secure interoperability within the EigenLayer ecosystem.

EigenDA offers several key attributes:

  • Scalability: EigenDA's write throughput scales linearly with the number of operators. At launch, it will provide a write throughput of 10 MB/s, a fivefold increase over its closest competitor.
  • Security: EigenDA comprises numerous operators registered in EigenLayer. These operators have delegated stake, which acts as a deterrent against misconduct.
  • Decentralization: Inspired by Danksharding, EigenDA's design extends Ethereum-native data availability beyond the capabilities of EIP-4844. Blob writes on EigenDA are recorded through Ethereum contracts, exposing operators to potential slashing risks. Ethereum Layer 2 solutions leveraging EigenDA eliminate the need for trust in another chain's light client, reducing the risk of manipulation by dishonest validator sets.

How to restake with EigenDA?

You can restake multiple LSTs to earn a yield, delegating tokens to Operators of your choice.

We recommend using a Ledger Hardware Wallet to keep full control over your funds. To nominate your tokens, you should ensure you have your ETH or LSTs on MetaMask or Rabby Wallet and follow the steps below:

Step 1: Open the EigenLayer App and connect your wallet.

Step 2: Proceed to the Restake tab.

Step 3: Select the asset to restake.

Step 4: Input the desired amount and click “Deposit”.

Step 5: Approve and confirm the transaction in your wallet.

​​Step 6: Continue to the AVS tab.

Step 7: Select EigenDA to restake.

Step 8: Scroll down to the Operators section and choose one of the options.

Step 9: Click “Delegate” to deposit tokens to the Operator.

Step 10: Token Approval. Once the token approval transaction is confirmed, you will be prompted to confirm the deposit transaction.

Step 11: Confirm the deposit transaction in your wallet.

What are the risks of restaking?

Restaking presents exciting opportunities for users to increase their yield, but it also comes with risks that must be carefully managed. Users must navigate the diverse range of AVSs launching on EigenLayer, each with its own slashing rules and risk profiles.

Slashing risk: These risks encompass the potential for slashing, which occurs when validators violate restaking terms, leading to penalties and potential losses. This penalty could impact restakers who entrust assets to Operators. Like any staking activity on Ethereum, the ETH you commit is subject to network regulations, with breaches potentially resulting in partial or total token losses. Slashing is not yet implemented on EigenLayer, therefore, it is a future risk. However, it is going to be introduced later this year.

Systemic risk: Vulnerabilities associated with restaking include operation concentration and the potential impact on Ethereum's security. The interconnectedness of AVSs within EigenLayer can amplify risks, as security issues with one AVS may affect others, leading to systemic failures.
