Required conditions

The vault integration ACL must enable this integration before the instruction is accepted; that enablement is defined on the GLAM state account.
If the signer is not the owner, the delegate ACL on the GLAM state must contain the exact protocol permission required by this instruction; registering a delegate alone is insufficient.
Instruction-specific destination accounts must satisfy the external protocol's own account model; GLAM validates the accounts it needs for authorization and policy enforcement, then passes the remaining protocol accounts through CPI.

Policy & permissions

Requires a Vault GLAM state.
Caller: GLAM owner, or a delegate with CCTP Transfer.
The CCTP policy gates the (destination_domain, mint_recipient) pair against an allowlist; asset and amount are not gated.
