Multisig Migration to Account Abstraction Tool

WHAT IT DOES

Multisig Migration to Account Abstraction Tool enables seamless transition from traditional multisig wallets (e.g., Gnosis Safe) to modern ERC-4337 account abstraction wallets. It scans the multisig to read its configuration—owners, threshold, pending transactions, nonce, and asset balances (native ETH and ERC-20 tokens). The tool then deploys a new AA wallet using a factory contract, transfers all assets from the multisig to the new wallet, and initializes any desired modules or hooks. The migration is executed as a coordinated sequence, ensuring that the multisig's funds and control logic are fully moved to the AA wallet without manual per-asset transfers.

This tool is critical for DAOs, treasuries, and power users who want to upgrade their wallet infrastructure to leverage account abstraction features like gas sponsorship, batched transactions, social recovery, and custom validation logic while preserving the security of multisig governance.

HOW TO USE

1. Connect your EVM wallet to the network where the multisig is deployed.

2. Enter the address of the multisig wallet you want to migrate.

3. Provide the ERC-4337 factory contract address that will deploy the new AA wallet.

4. Optionally set a salt for deterministic deployment, or leave blank for random.

5. Enter any AA modules to initialize (comma-separated addresses), such as session key managers or recovery modules.

6. Click "Scan Multisig" to read the wallet's configuration and balances. The tool will display owners, threshold, pending transactions, and asset holdings.

7. Review the migration summary, including the estimated gas cost and the list of assets to be transferred.

8. Click "Execute Migration" to deploy the AA wallet, transfer all ETH and tracked ERC-20s, and initialize modules.

TECHNICAL MECHANISM

The tool uses a multi-step sequential transaction flow to ensure atomicity where possible. First, it reads multisig data via standard interfaces: getOwners(), getThreshold(), nonce(), and balanceOf() for tracked ERC-20s. It estimates gas for each step using provider.estimateGas() with a 20% buffer to account for network variability. The migration deploys the AA wallet by calling createAccount(owner, salt) on the factory contract, which computes the wallet address deterministically. ETH is transferred by creating a multisig transaction (or direct transfer if the connected wallet is the multisig owner) that sends the balance minus gas costs to the new AA address. ERC-20 transfers use the transfer() method on each token contract. Module initialization calls module.init(wallet) on each provided module address. All transactions are sent sequentially and awaited, with progress displayed via a progress bar. Gas costs are calculated from receipt.effectiveGasPrice, not tx.gasPrice, to reflect actual post-EIP-1559 fees.

WHAT IT CANNOT SEE

This tool cannot migrate assets that are staked, locked, or deposited in protocols with withdrawal delays—such as L2 bridges, staking contracts, or vesting schedules. It cannot migrate contract ownership or delegate calls that the multisig controls, as those require separate governance processes. It cannot guarantee that the AA wallet is fully functional with all intended modules and hooks; module initialization may fail if the module's ABI or initialization requirements are incompatible. The tool does not simulate the migration before execution, so if the multisig transaction queue contains pending operations, those are not migrated (only assets and configuration are transferred). It cannot recover assets if the migration transaction is misconfigured, fails partway, or if the AA wallet's modules are incorrectly set up. Users should test on testnet and verify all addresses before mainnet migration.

PLEASE NOTE

EVM chains only. This tool assumes the multisig follows the Gnosis Safe interface (or compatible). The AA factory must be ERC-4337 compliant. Always verify the factory and module addresses—incorrect addresses can lead to loss of funds. The migration requires sufficient ETH in the multisig to pay for all transaction gas. Consider migrating during low network congestion to reduce costs.
