DAO Treasury Multi-Sig Signer Rotation Tool

WHAT IT DOES

DAO Treasury Multi-Sig Signer Rotation Tool enables DAOs and organizations to manage their treasury multi-sig signer set efficiently. It reads the current multi-sig configuration—owners/signers list, threshold, nonce, and pending transactions—then allows authorized signers to add new signers, remove existing signers, and update the threshold in a single coordinated workflow. The tool supports both direct execution (for multi-sigs that allow owner-managed changes) and proposal-based execution (for DAOs that require governance approval before signer changes take effect).

This tool is essential for DAOs, investment funds, and organizations that need to regularly rotate signers due to team changes, security best practices, or governance requirements. It eliminates manual transaction composition and reduces the risk of misconfiguration during signer management.

HOW TO USE

1. Connect your EVM wallet (must be a current signer for direct execution, or a governance participant for proposal-based execution).

2. Enter the multi-sig wallet address you want to manage.

3. Enter the addresses to add as signers (one per line) and the addresses to remove (one per line).

4. Optionally set a new threshold—leave blank to keep the current threshold.

5. Select the execution method: Direct (requires owner signature) or Via proposal (governance/DAO execution).

6. Click "Check Multi-Sig" to read the current configuration, validate your proposed changes, and preview the resulting signer count.

7. Review the proposed changes—the tool validates that the new threshold is between 1 and the resulting number of signers.

8. Click "Execute Rotation" to apply the changes. For direct execution, the tool submits the transactions sequentially. For proposal execution, it prepares a governance proposal for voting.

TECHNICAL MECHANISM

The tool reads multi-sig configuration using standard functions: getOwners() returns the list of current signers, getThreshold() returns the required number of signatures, and nonce() provides the transaction counter. The tool validates the proposed changes by computing the resulting signer count and ensuring the new threshold is valid. For execution, it attempts to call addOwner(address), removeOwner(address), and changeThreshold(uint256) sequentially, with gas estimation providing a 20% buffer. If the direct method fails (e.g., due to a multi-sig that requires proposal execution), the tool falls back to preparing a proposal transaction for governance execution. All transactions are submitted sequentially with progress tracking, and gas costs are calculated from receipt.effectiveGasPrice.

WHAT IT CANNOT SEE

This tool cannot verify the off-chain identity or trustworthiness of new signers—it only checks that the addresses are valid and not already signers. It cannot enforce governance rules outside the multi-sig's own logic; if the multi-sig allows direct changes, the tool will execute them without DAO voting. It cannot recover access if too many signers are removed simultaneously, potentially locking the treasury below the threshold. It cannot detect compromised signers who still hold their keys—the tool only manages the address list, not key security. It cannot rotate signers on non-EVM chains or across multiple multi-sigs in a single transaction. Always ensure at least one trusted signer remains after removal.

PLEASE NOTE

EVM chains only. This tool assumes the multi-sig follows the Gnosis Safe interface (or compatible). Not all multi-sig implementations support all functions. Always test on testnet before applying changes to a treasury. Removing signers is irreversible—ensure you have the proper authority and quorum before proceeding.
