Description

This Rust class is allows for canisters to hold assets on other EVM based chains.

This bounty gives the opportunity to

• learn Rust
• learn about signing transactions
• learn about evm transactions
• learn about t-ecdsa
• learn about managing nonces

The NoKey wallet is a stable class that any Rust canister can add that will allow it to act as a wallet for Evm-based chains. It should implement the following features:

• Derive a t-ecdsa key according to a consistent derivation scheme.
• Save that derivation for the user in a (Nat,Text) pair.
• Sign Evm-based transactions with a t-ecdsa key selected by the wallet owner. The transaction will be passed in as part of the sign function sign(rawtrx, {#derivation([Nat], #named(id)}, nonce, other Info?, saveHistory)
• Keep a history of signed transactions.
• Enable clearing the history
• Provide an upgrade strategy, preferably using stable vars.
• Suggest and follow a safe nonce generation/management scheme that protects the user.

To apply for this bounty you should:

• 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

Selection Process

The ICDevs.org developer’s advisors will propose a vote to award the bounty and the Developer Advisors will vote.

Bounty Completion

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.

Bounty Abandonment and Re-awarding

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.

Funding

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 $40:1 ICP for the first 125 ICP out of the DFINITY grant and then 0.25:1 after that. 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 [email protected].
