Ambire Wallet Extension - Secure, fast and reliable self-custody for Ethereum & L2s

@ivshti The extension UI is clean and responsive great job on that.

@mia_arthur very easy, there's two ways to do batching

• when the app requests it - this is a one-click experience, the user doesn't even know they did a batch. Everything that normally happens with multiple signatures happens with one.

• manually by clicking "start a batch" instead of the main CTA (eg Swap) which will initiate a "pending" state in the dashboard, from there you can add multiple actions to the batch

So it's either transparent and seamless, or if the app doesn't support it or you want to intentionally do it (eg multiple swaps, multiple transfers) you can do it manually

@alfie_logan we use a publicly available list of malicious apps (kudos to MetaMask for maintaining it) to warn users. But most importantly, we simulate the outcome of each transaction before you sign it - you see all the balance changes.

@joey_k_moran we simulate the transactions and preview balance changes (see screenshot).

But the cool thing about Ambire is that we support simulations on ALL networks we support. This is quite unique and it's achieved thanks to NOT using a third-party provider: instead, we rely on the native RPC of the network, using our own method: it only needs the RPC to support eth_call, which all RPCs do.

@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.
