SUPPORTED NETWORKS
One multisig, 7 EVM mainnets
MyMultiSig deploys the same open-source contract on every supported network, so a wallet works the same way on Ethereum as it does on Polygon, Arbitrum, or Gnosis.
Owners, thresholds, and signatures are enforced by the contract onchain — the list below is where that contract can live today. Testnets are first-class: try the full create, sign, and execute flow with free test funds before committing real assets.
