fhe-delegation

To share encrypted FHE balances, use the grant-view command to grant read access for specific handles to a delegate address. You must wait a 1-2 minute propagation window before the delegate can successfully decrypt the data using view-as.

You can revoke encrypted read access for on-chain ACL handles by executing the revoke-view command. Preflight checks like getDelegationExpiry help avoid wasting gas if the delegation is already expired or does not exist before sending the transaction.

ACL delegation for FHE handles requires a live Zama FHE SDK and a properly configured wallet environment. These components are necessary to execute preflight checks, manage access controls, and interact with encrypted on-chain data.

Yes, you can override the contract address, such as targeting X402PaymentVerifier, to enable facilitator audits. This allows auditors to use view-as to read encrypted cUSDC balances by applying contract overrides on the verifier contract.

view-as fails immediately after grant-view due to a 1-2 minute on-chain and gateway propagation window. You must wait for this propagation to complete before decrypt requests can successfully read the encrypted FHE handles.

Preflight checks like isDelegated and getDelegationExpiry prevent wasted gas by verifying if an active delegation exists before you submit a revoke-view transaction. This ensures you only spend gas when an actual revocation is necessary.
