@@ -146,9 +146,6 @@ The Executor Contract MUST support the following methods
   - MUST ensure the quote’s expiry time has not passed
   - MUST transfer the payment to the designated `payeeAddress`
   - MUST make these inputs available for off-chain consumption (e.g. emit a Request for Execution event)
-- `addRelayInstructions(requestId, refundAddr, signedQuote, relayInstructions)` [WIP]
-  - This method is intended for off-chain integration to add additional instructions and/or payment in the event that the initial request was underpaid or underpriced (e.g. too low of a gasLimit)
-  - MUST meet all the requirements of `requestExecution`
 
 In order to minimize cost, this contract MUST NOT verify the signature on the Quote. The Quote SHOULD be verified by the submitting client code before being used in a transaction.
