This repository contains code for an ERC-6900 compliant plugin where one or more EOA accounts, ERC-1271 compliant contracts, or P256 passkeys can be owners of the account. Its core features include:
- Enable ECDSA verification of signatures, standard EOA signature verification.
- Enable ERC-1271 signature verification, standard contract owner signature verification.
- Enable Webauthn verification, secp256r1 (P256) passkey signatures verification.
- Multiple equal owners who have the same root access to account.
- Implements EIP-712.
- By default, owner validation is added for most of the account's native functions,
including:
installPlugin/uninstallPluginupgradeToAndCallexecute/executeBatch
This plugin is optimized for Ethereum layer 2 rollup chains but will work on all EVM chains. Signature verification always attempts to use the RIP-7212 precompile and, if this fails, falls back to using FreshCryptoLib. It conforms to these ERC versions:
Important
- FreshCryptoLib uses the
ModExpprecompile (address(0x05)), which is not supported on some chains, such as Polygon zkEVM. This plugin will not work on such chains, unless they support the RIP-7212 precompile. - When attempting to use the RIP-7212 precompile, the plugin will call the precompile
(
address(0x100)). However, since signature validation might be called during a user operation validation phase, it can violate ERC-7562 validation rule OP-041 on networks that don't support the RIP-7212 precompile. Therefore, this plugin won't be compatible with most bundlers on such networks.
After cloning the repo, run the tests using Forge, from Foundry
forge testTo run the static analysis tools, install the Python dependencies in requirements.txt
and the JavaScript dependencies using any npm-compatible
package manager:
pip install -r requirements.txt
bun install # or npm installThen run the full suite of tests, including static analysis, formatting, and gas checking:
bun run test # or npm run testMuch of the code in this repository started from Alchemy's Multi Owner Plugin implementation. It was also influenced by Coinbase's Smart Wallet.
