Function: renew(string calldata tokenId, bool isSynthetic, uint256 expiresAt, string calldata correlationId)

This function renews ownership tokens by updating their expiration dates. It can only be called by authorized cross-chain senders from Doma chain in response to domain renewals. It updates token expiration without ownership verification.

Inputs

  • tokenId

    • Control: Full.

    • Constraints: Converted to uint256 via Strings.parseUint().

    • Impact: Identifies the specific token to renew.

  • isSynthetic

    • Control: Not controlled.

    • Constraints: Must be false (synthetic tokens not implemented).

    • Impact: Distinguishes between regular and permissioned tokens.

  • expiresAt

    • Control: Full.

    • Constraints: Validated in ownershipToken().renew() via inherited validation logic.

    • Impact: New expiration timestamp for the token.

  • correlationId

    • Control: Full.

    • Constraints: N/A.

    • Impact: Used for cross-chain operation tracking and correlation.
