Access Control

Owner and Pauser Roles

Pausing the Native Toke Transfer (NTT) Manager Contract will disallow initiating new token transfers. While the contract is paused, in-flight transfers can still be redeemed (subject to rate limits if configured).

NTT can be paused on a particular chain by updating the paused parameter on the deployment to true via the NTT CLI, then performing ntt push to sync the local configuration with the on-chain deployment.

• Owner - full control over NTT contracts, can perform administrative functions. Has the ability to un-pause contracts if they have been paused
• Pauser - can pause NTT contracts to halt token transfers temporarily. This role is crucial for responding quickly to adverse events without a prolonged governance process. Cannot un-pause contracts

Note

While the Pauser can pause contracts, the ability to un-pause contracts is callable only by the Owner.

The Owner and the Pauser addresses can each pause the contract. Since the contract Owner address is typically a multisig or a more complex DAO governance contract, and pausing the contract only affects the availability of token transfers, protocols can choose to set the Pauser address to be a different address. Creating a separate Pauser helps protocols respond quickly to potential risks without going through a drawn-out process.

Consider separating Owner and Pauser roles for your multichain deployment. Owner and Pauser roles are defined directly on the NttManager contract.
