Glossary
The terms the app and these docs use for multisig accounts, signers and proposals.
Account
A multisig account: one Sui address controlled by several signers together. The app calls it a “pod”. See What a multisig account is.
Address
A 32-byte identifier on Sui that can own coins and objects. An account’s address is derived from its signers’ public keys, their weights and the threshold, so a different setup gives a different address. See Why the address depends on the setup.
Combined signature
The single signature that the app builds from the signers’ individual signatures when you execute a proposal. Sui checks it against the account’s address.
Digest
The unique ID of a transaction, computed from its bytes. Each proposal is identified by the digest of its transaction, and the app’s proposal links use it.
Epoch
A period of time on a Sui network. A transaction can name a last epoch it may run in; after that epoch ends, the proposal shows as expired and cannot execute.
Execution
Submitting a proposal’s transaction to the network with the combined signature, once it has enough weight. See Execution.
Gas
The fee a Sui transaction pays to run. A proposal’s gas is paid by the account itself, from its balance on that network.
Invitation
How a signer joins an account. Each signer accepts or rejects it by signing a message with their wallet; your own keys accept automatically when you create the account.
Network
A Sui network, such as mainnet or testnet. An account and its address are the same on every network, but each proposal belongs to one network, and balances differ between networks. See Accounts and networks.
Proposal
A transaction from the account that is waiting for signatures, stored together with the signatures collected for it. See How proposals work.
Proposal status
Where a proposal stands: Pending, Ready, Expired, Executed, Failed or Cancelled. See Statuses.
Proposer
Anyone who creates a proposal. Signers can propose, and an account can also have external proposers: addresses that can propose but not sign.
Public key
The public half of a wallet’s key pair. A signer is added to an account by their public key; the app accepts Ed25519, Secp256k1 and Secp256r1 keys. The app can find the key from an address once its wallet has signed in to the app, or once the address has sent a transaction. See Signers and public keys.
Signature
Proof, made in a wallet, that the holder of a key approved a specific transaction or message. The app never sees your private key, only the signatures your wallet makes.
Signed message
A message, not a transaction, that you sign in your wallet. Signing in, answering an invitation, adding or removing an external proposer and cancelling a proposal each need one. See What needs your signature.
Signer
One of the public keys that control an account, each with a weight. See Signers and public keys.
Threshold
The total weight of signatures a proposal needs before it can execute. It is a whole number from 1 up to the sum of all signers’ weights. See Weights and the threshold.
Wallet
The software that holds your private key and makes your signatures. The app asks for signatures through the Sui wallet standard from whichever wallet you connect, and the wallet shows its own view of what you sign. Signing in with a wallet registers its public key with the service, so other people can add your address as a signer. See Check what you sign.
Weight
How much a signer’s signature counts toward the threshold, a whole number from 1 to 255. See A worked example.
