Native Token Transfers Post Deployment＃
To offer the best user experience and ensure the most robust deployment, Wormhole contributors recommend the following after you have deployed Native Token Transfers (NTT):
- Implement a robust testing plan for your multichain token before launching
- Ensure comprehensive, documented security measures are followed for custody of contract ownership, control of keys, and access control roles. Check the NTT configuration for more details on ownership and rate limits
- Consider a streamlined, customizable frontend such as Connect for an optimized user experience
- Alternatively, the Wormhole TypeScript SDK allows for a direct integration into your infrastructure
- Ensure ecosystem actors such as block explorers, automated security tools (such as BlockAid and Blowfish), and wallets (such as MetaMask, Backpack, and Phantom) are aware of your multichain deployment and that it is labeled appropriately
- Monitor and maintain your multichain deployment
Manual Relaying for Solana Transfers＃
By default, NTT transfers to Solana require manual relaying, meaning that after initiating a cross-chain transfer, the recipient must submit an on-chain transaction to claim the tokens.
This step ensures that tokens are properly minted or unlocked on Solana and prevents unauthorized claims.
Post-Deployment Settings＃
The following table outlines post-deployment settings available on the NTT Manager contract. These allow you to update roles, pause activity, and adjust transfer limits—useful for upgrades, incident response, or protocol tuning after initial deployment.
| Setting | Effect |
|---|---|
pause |
Pauses the manager |
unpause |
Unpauses the manager |
setOwner |
Changes the manager owner |
setPauser |
Changes the pauser role |
setOutboundLimit |
Sets outbound transfer limit |
setInboundLimit |
Sets inbound transfer limit (per chain) |
setTransceiverPauser |
Changes pauser for a transceiver |
