@dcbuilder is this the wallet that the app uses? https://github.com/worldcoin/hubble-bls-wallet/blob/main/contracts/contracts/BLSWallet.sol

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.

Some background... Hubble BLS, created by devs in PSE.dev, was optimised for cheap token txs. Worldcoin (others?) forked this for preliminary use. BLS Wallet (also PSE) used the BLS primitives and a bespoke smart contracts to do more than just erc20. With the attention on 4337, bls wallet is now in maintenance mode.
