This rust canister allows motoko canister to query it with data to receive EVM compliant transactions that can be signed via t-ECDSA and submitted to EVM networks.
This bounty gives the opportunity to
- learn rust
- learn about signing transactions
- learn about evm transactions
- learn about t-ecdsa
Motoko currently is missing a number of libraries needed to encode, interpret, and sign evm transactions and data. Rust has most of these libraries and many of them have been used in the rust No Key Wallet project. Until these libraries are converted to motoko, it would be nice to have a utility canister that does most of this work for a motoko canister. This will involve async communication and may incur long transaction times, but it will at least let motoko devs get started with EVM based transactions while those motoko libraries are being developed.
- Create a proper candid type for passing an EVM transaction to the utility canister and return the encoded bytes and hash that is needed to be signed. Support multiple network ids and transaction types like Legacy, EIP1559, EIP2930.
- Create a proper candid type for passing in an evm witness, root, and receiving back a verification that the data is part of the tree under that root.
- Expose RLP encoding and candid type
- Expose a keccak hashing function
- Expose functions similar to ethereumjs-monorepo/packages/util at master · ethereumjs/ethereumjs-monorepo · GitHub
- Include links to previous work writing tutorials and any other open-source contributions(ie. your github).
- Include a brief overview of how you will complete the task. This can include things like which dependencies you will use, how you will make it self-contained, the sacrifices you would have to make to achieve that, or how you will make it simple. Anything that can convince us you are taking a thoughtful and expert approach to this design.
- Give an estimated timeline on completing the task.
- Post your application text to the Bounty Thread
The ICDevs.org developer’s advisors will propose a vote to award the bounty and the Developer Advisors will vote.
Please keep your ongoing code in a public repository(fork or branch is ok). Please provide regular (at least weekly) updates. Code commits count as updates if you link to your branch/fork from the bounty thread. We just need to be able to see that you are making progress.
The balance of the bounty will be paid out at completion.
Once you have finished, please alert the dev forum thread that you have completed work and where we can find that work. We will review and award the bounty reward if the terms have been met. If there is any coordination work(like a pull request) or additional documentation needed we will inform you of what is needed before we can award the reward.
If you cease work on the bounty for a prolonged(at the Developer Advisory Board’s discretion) or if the quality of work degrades to the point that we think someone else should be working on the bounty we may re-award it. We will be transparent about this and try to work with you to push through and complete the project, but sometimes, it may be necessary to move on or to augment your contribution with another resource which would result in a split bounty.
The bounty was generously funded by the DFINITY Foundation. If you would like to turbocharge this bounty you can seed additional donations of ICP to 8e6a56cf83240d1f07afe5002d8ce3574e2bde9ede8c4a8964cd6b53c40d0c22. ICDevs will match the bounty 0.25:1. All donations will be tax deductible for US Citizens and Corporations. If you send a donation and need a donation receipt, please email the hash of your donation transaction, physical address, and name to firstname.lastname@example.org. More information about how you can contribute can be found at our donations page.
The draft bounty is posted to the DFINITY developer’s forum for discussion
The developer advisor’s board will propose a bounty be ratified and a vote will take place to ratify the bounty. Until a bounty is ratified by the Dev it hasn’t been officially adopted. Please take this into consideration if you are considering starting early.
Developers can submit applications to the Dev Forum post. The council will consider these as they come in and propose a vote to award the bounty to one of the applicants. If you would like to apply anonymously you can send an email to austin at icdevs dot org or sending a PM on the dev forum.
A developer is currently working on this bounty, you are free to contribute, but any splitting of the award will need to be discussed with the currently assigned developer.
