Does this skill handle private keys?

No, the skill is intentionally designed to be read-only and proposal-only; it never requests or stores private keys or signatures, acting only as a cryptographic safety layer.

What libraries is the output compatible with?

The generated EIP-712 typed data is designed to be natively compatible with viem's signTypedData function, ensuring a modern and developer-friendly workflow.

What safety checks are included?

The skill warns users about high ETH values relative to balances, empty calldata, and inconsistencies in owners or thresholds to prevent irreversible errors.

Is this compatible with Gnosis Safe?

No, this skill is specifically designed for custom Solidity MultiSig implementations, such as those from Solidity-by-Example or MinimalMultisig, rather than the Gnosis Safe ecosystem.

Does it execute transactions on-chain?

No, the skill only assists in the preparation and validation phase. Final signing and on-chain execution must be performed by the authorized wallet owners using their own tools.

セキュリティとテスト

Simplifies Solidity-based MultiSig transaction preparation with safe, structured EIP-712 typed-data generation.

The Claude Code MultiSig Wallet Skill provides a secure, vendor-neutral framework for preparing and validating transactions for custom Solidity MultiSig wallets. Designed specifically for teams not using Gnosis Safe, it transforms natural language requests into structured, viem-compatible EIP-712 typed data without ever touching private keys. This skill acts as a critical safety layer for DAO treasuries and protocol operations by providing human-readable explanations, automated safety warnings, and strict validation of transaction parameters before they are signed off-chain.
