Threshold ECDSA
Signer Program: tecdsa_sign
Nillion's threshold ECDSA (tECDSA) signer uses a "builtin" Nada program that streamlines the signing process.

Required Identifiers
The tecdsa_sign program has a pre-configured set of identifiers that you'll need to use when storing a tECDSA private key or signing a message:
# program id
tecdsa_program_id = "builtin/tecdsa_sign"`
# input names
tecdsa_key_name = "tecdsa_private_key"
tecdsa_digest_name = "tecdsa_digest_message"
tecdsa_signature_name = "tecdsa_signature"
# party names
tecdsa_key_party = "tecdsa_key_party"
tecdsa_digest_party = "tecdsa_digest_message_party"
tecdsa_output_party = "tecdsa_output_party"
These predefined identifiers allow you to quickly integrate with Nillion's built-in tECDSA signing functionality, without needing to configure or manage the underlying program details. By using these values, you can get up and running with threshold ECDSA signing faster.
