Transaction Authentication

Learn about types of transaction authentication.

Intent Signing

Intent signing provides a compact domain separator to data signed by both user and authority signatures. Data that each signature commits to is called an intent message, which all signatures on Sui must include.

→

Multisig

Multi-signature (multisig) transactions require multiple keys for authentication rather than a single key. Sui supports multisig transactions for pure Ed25519, ECDSA Secp256k1, and ECDSA Secp256r1 encryption keys.

Offline Signing

Offline signing can be used to sign a Sui transaction when a device is not connected to a Sui network, or if the signing wallet uses a different programming language than that of the transaction being signed.
