Ambire Wallet

@leo_cobain we already support smart wallets, but EIP-7702 allows traditional accounts to become smart up to an extent that makes smart accounts less valuable.

For example, gas sponsorship and batching are available on traditional accounts (aka EOAs) now.

As for multisigs, we do plan to integrate with Safe.

@hannah_jhon awesome question!

The Ethereum protocol (and L2s/most alt L1s) don't actually support gas sponsorship under the hood. What happens is that an automated "agent" (called a relayer or bundler) broadcasts the transaction, but you still authorize the account operations with an elliptic curve signature. This is made possible thanks to account abstraction, and now thanks to the Pectra upgrade it's possible for ALL accounts, not just smart accounts.

Now from the user perspective, either the dapp funds the transaction, or the user still pays for it via another token they have, for example USDC, which eliminates the friction of needing to have native tokens on each L1/L2 you try to operate. We have a feature called the Gas Tank where you pre-fund from any network and then spend on any other.

This not only eliminates friction, but increases privacy as well, because many folks get stuck trying to transact on a L2 because they don't have the gas token, and they fund their account from another account, or from a CEX, both of which compromise the privacy. Meanwhile on Ambire, you can just use your Gas Tank balance to pay on any network, or in some (still rare, but getting more common) cases the app pays for the transaction.

@jackson_wells we're already integrated with Optimism, Arbitrum, Base, Scroll, Linea and a few others, as well as some alternative layer 1s like BNB Chain.

We're considering more integrations as well, but built-in networks are not our top priority since we support all EVM networks anyway.
