This Solidity smart contract implements a multi-signature wallet, allowing multiple authorized signers to collectively approve and execute transactions.
The MultiSigWallet contract requires a specified quorum of signers to approve a transaction before it can be executed. It supports functionalities like initiating transactions, approving transactions, adding valid signers, and transferring ownership.
- Initiate Transaction: Allows any valid signer to propose a transaction by specifying the amount and receiver address.
- Approve Transaction: Valid signers can approve a proposed transaction, and once the quorum is reached, the transaction is executed, transferring the specified amount to the designated receiver.
- Add Valid Signer: The owner can add new valid signers to the contract.
- Transfer Ownership: The owner can transfer ownership of the contract to another address, and the new owner must claim ownership to finalize the transfer.
initiateTransaction(uint256 _amount, address _receiver): Initiates a transaction proposal.approveTransaction(uint256 _txId): Approves a transaction if the signer is valid and the quorum is not reached.addValidSigner(address _newSigner): Allows the owner to add a new valid signer.getAllTransactions(): Retrieves all transactions initiated.transferOwnership(address _newOwner): Initiates the transfer of ownership to a new address.claimOwnership(): Finalizes the transfer of ownership.
To use this contract, deploy it on the Ethereum network with a list of initial valid signers and a specified quorum. After deployment, authorized signers can initiate and approve transactions according to the contract rules.
