How to Interact with a Multisig Contract

2 min read

Step 1. Access your wallet and head to the ‘Contracts’ section, to the left of your wallet interface.

Step 2. Locate your preferred Multisig Contract ABI in the dropdown, or manually enter the contract’s ABI.

Step 3. Check the contract address to make sure it’s the one you’re looking for, then press ‘Continue’.

• You may need to enter your contract address in the ‘Contract Address’ field at the top.

Step 4. Select ‘Execute’ from the dropdown menu.

• Enter the address you want to send to in the _To field.
• Enter the amount you want to send in the _Value field.
• In the Data field, type 0x. This sets it to empty.
• Leave the Value in ETH as 0.
• Click Write.
• Confirm the transaction and send.

Step 5. Click the Transaction ID that outputs with the ‘Success’ message. Copy this ID.

Step 6. If it’s a multisig contract with two owners, you will need to refresh this page and choose ‘Confirm’.

• In Step 5, you opened the Transaction ID from the ‘Execute’ call. Your page should look like this example of a transaction hash.
• Click the ‘Event Logs’ tab.
• For reference, in this example of event logs (note this is not YOUR information, it’s an example), the _h value would be 9228aeaf3ed560274899483646ea4ce9b322bccffac60cac2d035d08752617f4.
• Check the link above where it says that string, and then compare it to find what YOUR _h value is. It will be different than what we provided as an example.
• Go back to MEW, where you have the ‘Confirm’ page open, and paste your string into the _h field.
• Click ‘Write’ again.
• Confirm and send the transaction.

Step 7. Double-check to confirm everything went as intended.

Step 8. If your multisig is a 3 of 5 multisig, you will repeat the confirm process outlined in Step 6 until it reaches the necessary approvals. Luckily, the _h value will remain the same for each of them.

Step 9. You can view another approval from our example of the event logs from before.

Step 10. Feel free to repeat this process whenever you want to send ETH.
