Learn how MultiSigWallet smart contracts revolutionize secure transactions on BitTorrent Chain (BTTC) with multi-signature capabilities.





According to BitTorrent Inc., the introduction of the MultiSigWallet smart contract to BitTorrent Chain (BTTC) will revolutionize the way secure transactions are performed on blockchains. This innovative smart contract enhances security by requiring multiple approvals before executing a transaction.

MultiSigWallet Contracts: Collaborative Digital Vaults

The MultiSigWallet contract acts like a digital vault that requires multiple keys to open, ensuring that no one person can access the funds alone. This feature is particularly advantageous for managing shared funds with enhanced security and consensus.

State Variables and Structures: Building Blocks

The core components of a MultiSigWallet contract are:

  • owner: An array of addresses that have ownership.
  • Number check: The number of confirmations required to execute a transaction.
  • transaction: A structure that defines the structure of each transaction.
  • Confirmed: A nested mapping to track confirmations for each transaction.
  • I am the owner: A mapping to quickly check if an address belongs to the owner.
  • work: An array that stores all submitted transactions.

Event: Ensuring Transparency

Events are critical to off-chain tracking and transparency.

  • Transaction submitted: Occurs when a new deal is proposed.
  • Transaction confirmed: Issued when the owner confirms the transaction.
  • Transaction executed: This is the log when the transaction was executed successfully.

Constructor: Initialize Wallet

The creator of the MultiSigWallet contract initializes a wallet with a specified owner and confirmation threshold.

constructor(address() memory _owners, uint _numConfirmationRequired) 
require(_owners.length > 1, "owners required must be greater than 1");
require(
_numConfirmationRequired > 0 &&
_numConfirmationRequired <= _owners.length,
"Num of confirmation is not sync with num of owner"
);
numConfirm = _numConfirmationRequired;

for (uint i = 0; i < _owners.length; i++)
require(_owners(i) != address(0), “Invalid owner”);
owner.push(_owners(i));
isOwner(_owners(i)) = true;

This ensures that the wallet has at least two owners, the required number of confirmations is valid, and that all owner addresses provided are valid.

Key features: Core of multi-signature operations

Submit a transaction

Anyone can propose a new deal using the following features:

function submitTransaction(address _to) public payable 
require(_to != address(0), "Invalid address");
require(msg.value > 0, "Transfer amount must be greater than 0 ");
uint transactionId = transactions.length;

Transaction.Push(
transaction(to: _to, value: msg.value, executable: false)
);

Export TransactionSubmitted(transactionId, msg.sender, _to, msg.value).

Transaction confirmation

Only the owner can verify the transaction.

function confirmTransaction(uint _transactionId) public onlyOwner 
require(_transactionId < transactions.length, "Invalid transaction");
require(
!isConfirmed(_transactionId)(msg.sender),
"Transaction is already confirmed by owner"
);
isConfirmed(_transactionId)(msg.sender) = true;
emit TransactionConfirmed(_transactionId);

if (Transaction confirmed(_Transaction ID))
Execute transaction(_transaction ID);

Check transaction confirmation status

This view function verifies whether a transaction has received the required number of confirmations.

function isTransactionConfirmed(
uint _transactionId
) public view returns (bool)
require(_transactionId < transactions.length, "Invalid transaction");
uint confirmation;
for (uint i = 0; i < numConfirm; i++)
if (isConfirmed(_transactionId)(owners(i)))
confirmation++;


return confirmation >= numConfirm;

Execute a transaction

Once the required number of confirmations is reached, the transaction can be executed.

function executeTransaction(uint _transactionId) public payable 
require(_transactionId < transactions.length, "Invalid transaction");
require(
!transactions(_transactionId).executed,
"Transaction is already executed"
);

(bool success, ) = transaction(_transactionId).to.call
Value: transaction(_transactionId).value
(“”);

require(success, “Transaction execution failed “);
transaction(_transactionId).execute = true;
Export TransactionExecuted(_transactionId).

Beyond the Basics: The Power of Multi-Signature Wallets

MultiSigWallet contracts offer numerous advantages:

  • Enhanced security: Multi-authorization reduces unauthorized transactions.
  • Shared Control: Suitable for business accounts or joint funds.
  • transparency: Blockchain records ensure accountability.
  • pliability: You can customize the number of owners and confirmations.

Conclusion: The Future Security of Digital Assets

MultiSigWallet smart contracts represent a significant advancement in digital asset security and management. By requiring multiple signatures for transactions, they create a robust and reliable system for handling funds on the blockchain. This innovation is poised to set a new standard for secure digital finance.
