Accelerate a stuck transaction

• Accelerate a transaction based on the payment ID. It should be used when a transaction associated with the payment is broadcasted but not confirmed for a long period of time (i.e 10 minutes). This is usually due to gas fees being too low and not picked up by any miner/validator.

• The /accelerate endpoint essentially creates another transaction with the same params as the broadcasted transaction. If multiple broadcasted transactions exist, it will use the newest created one. Afterwards, OFI can sign with a higher gas fee and submit via /submit endpoint to accelerate blockchain confirmation.

• Requirements for using this endpoint:

  • No COMPLETED transaction exist for the payment (otherwise onchain transaction has completed)

  • No CREATED transaction exist for the payment, otherwise OFI should sign that transaction and submit

  • No PENDING transaction exist for the payment, otherwise OFI should wait for transaction to be broadcasted

• In another word, all existing transaction for the payment should either be FAILED (which is no longer effective) or BROADCASTED (which means they are stuck onchain and not confirmed)
