Smart Account Batch Deployment Across Chains

WHAT IT DOES

Smart Account Batch Deployment Across Chains enables users to deploy multiple ERC-4337-compatible smart accounts (account abstraction wallets) across one or more EVM chains in a single workflow. The tool reads the factory contract state to compute deterministic addresses for each account based on the owner address and salt, then submits deployment transactions to each target chain. Users can configure accounts with different owners on different chains, optionally initialize modules during deployment, and preview the computed addresses before executing any on-chain transactions.

This tool is essential for power users, DAOs, protocols, and developers who need to deploy consistent smart account infrastructure across multiple chains—whether for cross-chain identity, unified wallet management, or protocol-owned accounts. It eliminates manual per-chain deployment steps, ensures address consistency where desired, and provides visibility into the entire deployment process.

HOW TO USE

1. Connect your EVM wallet to any supported chain—the tool will switch networks as needed during deployment.

2. Enter the ERC-4337 factory contract address (must be deployed on each target chain, or use the same address if deployed deterministically).

3. Add accounts to deploy by specifying chain ID, owner address, and optionally a salt for deterministic addressing. Each row represents one account on one chain.

4. Optionally specify module addresses to initialize during deployment.

5. Click "Preview Addresses" to compute the deterministic addresses for each account without sending any transactions—the tool will show where each account will be deployed.

6. Review the account list, chain assignments, and computed addresses in the review panel.

7. Click "Deploy Accounts" to execute the batch deployment. The tool will automatically switch to each chain, submit the deployment transactions, and track progress.

8. Monitor progress via the status bar and review the deployment results (deployed, already existed, failed).

TECHNICAL MECHANISM

The tool uses the factory contract's createAccount(owner, salt) function to deploy new smart accounts and getAddress(owner, salt) to compute addresses deterministically. For each account, the tool computes the salt as a bytes32 value from the user-provided salt string. Before deploying, it checks if the account already exists by calling getAddress and checking the code at that address. If not deployed, it estimates gas using createAccount with a 20% buffer and submits the transaction. The tool groups accounts by chain and switches networks sequentially using BGWallet.switchNetwork(). Progress is displayed via a status bar showing deployment progress across all accounts. Gas costs are calculated from receipt.effectiveGasPrice. The tool supports multiple EVM chains via the connected wallet's ability to switch networks.

WHAT IT CANNOT SEE

This tool cannot guarantee that accounts are deployed with the correct configuration across all chains if the factory or initialization logic differs between chains—different chain deployments may have varying implementation versions. It cannot recover funds sent to precomputed addresses if deployment fails; if a transaction reverts, the address may remain un-deployed but any funds sent directly to it would be lost. It cannot verify that the deployed accounts are fully functional with all intended modules and hooks—modules must be initialized correctly and may require additional setup. It cannot deploy accounts on chains where the factory contract does not exist or where the wallet lacks sufficient native balance for gas—the tool will fail on those chains. It cannot monitor deployment status across chains after submission; users must verify independently. The tool does not validate that the factory contract is the correct ERC-4337 implementation or that the owner address is valid.

PLEASE NOTE

EVM chains only. This tool requires that the factory contract is deployed on each target chain. The connected wallet must have sufficient native balance on each chain to cover gas costs. The tool does not batch deployments into a single transaction across chains—each chain requires a separate transaction due to cross-chain limitations. Always preview addresses before deploying to ensure correctness. The tool assumes the factory implements the standard ERC-4337 interface; custom factories may require different function signatures.
