Transaction Authentication

Index page for transaction authentication section.

Sui supports multiple transaction authentication methods, from standard cryptographic key pairs (Ed25519, ECDSA Secp256k1/r1) to multisig wallets, zkLogin for OAuth-based authentication, and passkeys for biometric signing.

Signing and Sending Transactions

Understanding cryptographic keys, addresses, and signatures on Sui. Sui supports multiple cryptography algorithms and primitives with rapid switching between them.

Multisig Authentication

Guide on how to create a multisig transaction and then submit it against a local network using the Sui CLI.

→

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.

→

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.

→

Address Aliases

Address aliases can be used to configure the set of keys that are allowed to sign transactions for a particular address on the Sui network.
