Ankr Supports the Ethereum 2.0 Deposit Contract

As everyone knows now, Ethereum 2 phase 0 is imminent. One key step for this to happen is for the community to agree upon a canonical deposit contract address to kickstart the Genesis process.

In order to agree upon this, it requires numerous third parties to check the contract and confirm approval that everything is correct. The more third parties carry out this validation, the greater the confidence instilled in the community that the address is valid and correct.

This article represents Ankr’s approval of the contract address, resulting from our own verification carried out in accordance with the steps described by other community members.

We arrived at this decision after independently verifying that the bytecode deployed at the contract address is exactly the same as what we could reproduce by compiling the contract’s Solidity source code in a local build.

We are publishing this important announcement to notify that we are joining other members of the Ethereum community to support the use of this ETH2.0 deposit contract address for the genesis process and beyond.

Independent Verification

In accordance with the same steps described by the Status and Nimbus teams in their own declaration of support, Ankr carried out these same steps for our validation process. Thanks to the Status and Nimbus projects for documenting the validation steps described below:

The contract at the above address was created at timestamp  as per Etherscan by a transaction with hash .

The contract source code has been verified on Etherscan where it notes that the contract was compiled using Solidity compiler version  and optimization enabled with 5000000 runs.

The following steps outline our verification process:

  1. We obtained the bytecode at this address on the Ethereum blockchain using the  method (via Infura).
  2. We cloned the repository from  and followed the compilation instructions for the deposit contract.
  3. We downloaded Solidity compiler version for Linux.
  4. We compiled in the repository with this command: which gave us the runtime bytecode for this contract.
  5. We compared the bytecode we obtained and found them to be the same.

Conclusion

The critical Ethereum 2.0 deposit contract (which was originally written in Vyper) was re-written in Solidity, reviewed by Solidity experts and then formally verified by Runtime Verification as explained in this blog post by Ethereum Foundation. It has now been deployed on the mainnet at address .
