🛠 How to Use AptosEdge

1. Create a Multisig Wallet

Use the following command to create a multisig wallet with two admins and a threshold of two approvals:

create_multisig(&signer, vector[admin1, admin2], 2);

2. Create and Confirm a Transaction

Admins can create a new transaction:

create_transaction(&signer, multisig_creator, 1000, recipient_address);

Then confirm the transaction:

confirm_transaction(&signer, multisig_creator, tx_id);

3. Execute Transactions

Admins can execute transactions after receiving sufficient confirmations:

execute_transaction(&signer, multisig_creator, tx_id);

For batch execution:

execute_batch_transactions(&signer, multisig_creator, vector[tx1, tx2, tx3]);

4. Cancel a Transaction

Cancel a pending or unexecuted transaction:

cancel_transaction(&signer, multisig_creator, tx_id);
