Transfer Ownership＃

After deploying Native Token Transfers (NTT), you may need to move ownership to a new owner address (e.g., a multisig). This page outlines the process for transferring ownership on EVM, Solana, and Sui.

EVM＃

The NTT CLI supports transferring ownership on EVM chains. To transfer ownership on the EVM chains, you can do the following:

1. Set the private key used to sign the transaction.

   export ETH_PRIVATE_KEY=INSERT_EVM_PRIVATE_KEY
   

2. Run the ntt transfer-ownership command, specifying the chain and destination address.

   ntt transfer-ownership INSERT_CHAIN --destination INSERT_DESTINATION_ADDRESS
   

   You’ll see a confirmation prompt. Type y to proceed.

If successful, you will see the following output:

Solana＃

Transferring ownership of Wormhole's NTT to a multisig on Solana is a two-step process for safety. This ensures that ownership is not transferred to an address that cannot claim it. Refer to the transfer_ownership method in the NTT Manager Contract to initiate the transfer.

1. Initiate transfer: Use the transfer_ownership method on the NTT Manager contract to set the new owner (the multisig).
2. Claim ownership: The multisig must then claim ownership via the claim_ownership instruction. If not claimed, the current owner can cancel the transfer.
3. Single-step transfer (Riskier): You can also use the transfer_ownership_one_step_unchecked method to transfer ownership in a single step, but if the new owner cannot sign, the contract may become locked. Be cautious and ensure the new owner is a Program Derived Address (PDA).

For a practical demonstration of transferring ownership of Wormhole's NTT to a multisig on Solana, visit the GitHub demo, which provides scripts and guidance for managing an NTT program using Squads' multisig functionality, including procedures for ownership transfer.

Sui＃

The Sui CLI supports transferring ownership by moving the NTT Manager’s AdminCap and UpgradeCap to your multisig. You can transfer ownership as follows:

1. Find out the AdminCap and UpgradeCap for your NTT manager.

   sui client object INSERT_SUI_NTT_MANAGER_ADDRESS --json 2>/dev/null | jq -r '"AdminCap ID: \(.content.fields.admin_cap_id)\nUpgradeCap ID: \(.content.fields.upgrade_cap_id)"'
   

2. Transfer AdminCap object over to a multisig.

   sui client transfer --to INSERT_MULTISIG_ADDRESS --object-id INSERT_ADMIN_CAP_ID_STEP1
   

3. Transfer UpgradeCap object over to a multisig.

   sui client transfer --to INSERT_MULTISIG_ADDRESS --object-id INSERT_UPGRADE_CAP_ID_STEP1
   

4. Check the new owner of the AdminCap object.

   sui client object INSERT_ADMIN_CAP_ID_STEP1 --json \
       | jq -r '.owner'
