SKALE - Private key generation and token transfers

Goal

Create a means of transferring tokens between custodial wallets associated with users. If there are any obstacles, identify them and propose solutions.

What needs to be done

• See if we can use Nostr private keys to act as a user's custodial wallet for the site.
• If we cannot, find an alternative system of private key generation for users.
• Check wallets can be imported in Metamask and tokens can be sent between wallets.
• Build out a CLI endpoint that can be used to wire tokens between the wallets of two users.
• CLI endpoint should print TX hash (as when implemented fully, we will want to pass this to the front-end.

QA

• Test CLI endpoint works for users pre-seeded with testnet tokens.

UX/Design

N/A - though if any future UX considerations come up, we should consider it.

Personas

For now, developers, in future, users of the offchain system as outlined in &256

Experiments

N/A - this should NOT be exposed yet or accessible from existing API endpoints thus should not YET need a feature flag.

Acceptance Criteria

• SKALE compatible private keys associated with user accounts.
• Figure out sFuel distribution.
• CLI endpoint to transfer tokens between two users by user guid - should print TX hash.
• CLI endpoint for checking the balance of a wallet by address or user guid.
• CLI endpoint for sending sFuel to a wallet by address or user guid (should be the same as sending Ether).
• Unit tests.
