Signatures for Unsupported Chains
Our ECDSA and EdDSA signing algorithms allow you to sign any transaction and broadcast it to your own nodes. This will allow you to use our tMPC platform to securely sign any transaction.
If we don't support a chain natively and you wish to use our tMPC security, then get in touch! We do aim to support as many platforms as possible.
Most chains use the supported algorithms below.
