Signatures for Unsupported Chains

Integrate with any other chain that uses standard digital signature schemes

Our ECDSA and EdDSA signing algorithms allow you to sign transactions and broadcast it to your own nodes. You may use our tMPC platform to securely sign any transaction through the API.

If we don't support a chain natively and you wish to use our tMPC security, then get in touch and ask us to add it. We do aim to support as many platforms as possible.

Most chains use the supported algorithms below.
