Plutus.Contracts.MultiSigStateMachine
Description
A multisig contract written as a state machine.
Synopsis
- data Params = Params {
- mspSignatories :: [PaymentPubKeyHash]
- mspRequiredSigs :: Integer
- data Payment = Payment {
- paymentAmount :: Value
- paymentRecipient :: Address
- paymentDeadline :: POSIXTime
- data State s
- mkValidator :: Params -> ValidatorType MultiSigSym
- typedValidator :: Params -> TypedValidator MultiSigSym
- data MultiSigError
- = MSContractError ContractError
- | MSStateMachineError SMContractError
- type MultiSigSchema = (((Endpoint "propose-payment" Payment .\/ Endpoint "add-signature" ()) .\/ Endpoint "cancel-payment" ()) .\/ Endpoint "pay" ()) .\/ Endpoint "lock" Value
- contract :: (AsContractError e, AsSMContractError e) => Params -> Contract () MultiSigSchema e ()
Documentation
The n-out-of-m multisig contract works like a joint account of m people, requiring the consent of n people for any payments. In the smart contract the signatories are represented by public keys, and approval takes the form of signatures on transactions.
The multisig contract in
MultiSig expects n signatures on
a single transaction. This requires an off-chain communication channel. The
multisig contract implemented in this module uses a proposal system that
allows participants to propose payments and attach their signatures to
proposals over a period of time, using separate transactions. All contract
state is kept on the chain so there is no need for off-chain communication.
