A place for developers to talk about building on Farcaster.

Considering making all Warpcast wallets AA when we migrate to mainnet. What are the best AA wallet implementations out there today?

worldcoin did a great job with their smart contract wallet rollout and migration from polygon to op

can't find code rn, but they are talking about it here

No, we are using @safe smart contract wallets and using the gasless feature to subsidize cost (early user adoption incentive). The hubble bls wallet was a wallet for our own optimistic rollup that did bls signature aggregation of erc20 transfers and only that. We discontinued that project in favor of using Optimism

A BLS wallet will give you cheaper tx fees because of the ability to aggregate signatures.

You’d have to use a bundler that supports it.

Verifying individual BLS signatures on-chain is expensive pre-EIP-2537 (precompile awaiting merge).

It has some system design considerations.
