Access Control
Owner and Pauser Roles
Pausing the NTT manager contract will disallow initiating new token transfer. 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, and 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 is crucial for responding quickly to potential risks without a prolonged governance process. Cannot un-pause contracts.
Note that while the Pauser
has the ability to pause contracts, the ability to un-pause contracts is callable only by the Owner
.
The contract can be paused via the contract Owner
or the Pauser
address. Since the contract Owner
address is typically a multi-sig or a more complex DAO governance contract, and pausing the contract only affects the liveness of token transfers, protocols can choose set the Pauser
address to be a different address. This can help ensure that protocols are able to respond very 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
.
