This code defines a contract called DealMaker
that allows multiple parties to review and sign a contract, and then execute the deal once the required number of signatures have been collected. The contract is set up to accept an array of signatories, a required number of signatures, and the details of the deal (including the deal value and the recipient of the funds). The signContract
function allows parties to sign the contract, and the executeDeal
function allows the deal to be executed once the required number of signatures have been collected.
