Multisig Contract

4-of-7 threshold multisig for governance execution.

Storage​

owners: StoredAddressArray        // List of 7 owners
isOwner: AddressMemoryMap         // Quick lookup
threshold: StoredU256             // Required confirmations (4)
txCount: StoredU256               // Nonce for tx IDs

// Per transaction
txTarget: Map<u256, Address>
txSelector: Map<u256, u32>
txData: Map<u256, u256>
txConfirmCount: Map<u256, u256>
txExecuted: Map<u256, bool>

Transaction Flow​

1. Propose​

function propose(target, selector, data): u256 {
    require(isOwner[sender]);

    const txId = txCount++;
    txTarget[txId] = target;
    txSelector[txId] = selector;
    txData[txId] = data;
    txConfirmCount[txId] = 1;  // Proposer auto-confirms

    return txId;
}

2. Confirm​

function confirm(txId): void {
    require(isOwner[sender]);
    require(!confirmations[txId][sender]);

    confirmations[txId][sender] = true;
    txConfirmCount[txId]++;
}

3. Execute​

function execute(txId): void {
    require(txConfirmCount[txId] >= threshold);
    require(!txExecuted[txId]);

    txExecuted[txId] = true;
    Blockchain.call(txTarget[txId], encodeCall(txSelector[txId], txData[txId]));
}

Owner Management​

// Add owner (requires 4-of-7)
function addOwner(owner): void {
    onlySelf();
    owners.push(owner);
    isOwner[owner] = true;
}

// Remove owner (requires 4-of-7)
function removeOwner(owner): void {
    onlySelf();
    require(owners.length > threshold);
    owners.remove(owner);
    isOwner[owner] = false;
}

// Change threshold (requires 4-of-7)
function changeThreshold(newThreshold): void {
    onlySelf();
    require(newThreshold <= owners.length);
    threshold = newThreshold;
}
