404: Not Found Transaction not found.

Possible values for the status field of the transaction are:

• mined: Transaction has been included in the blockchain

• pending: Transaction is valid and could potentially be included in the next block

• nonce_too_low: Transaction can never be mined because its nonce is too low, effectively dropped.

• nonce_gapped: The transaction nonce is too high

• not_enough_funds: The transaction sender does not have a balance high enough to pay for the transaction

• base_fee_low: The base fee of the transaction is too low to be included in the next block

• low_priority_fee: The transaction's priority fee is zero

• not_enough_gas: The intrinsic gas of the transaction is too low.

• unknown: There was an issue determining the status of this transaction, check again later

• sanctioned: The sender or receiver is sanctioned by OFAC

• gas_limit_too_high: The gas limit for this transaction is higher than the block gas limit

• invalid_signature: The signature is invalid

• underpriced: There is a transaction with the same nonce that has a higher gas fee.

• expired: The transaction could not get mined in time and was discarded.

Possible values for the status field of the auction are:

• open: The auction is ongoing

• not_started: The auction has not started yet. The auction will only start when the transaction is pending.

• closed: The auction is closed and bids will be processed very soon.

• sent_to_relay: The auction bundle has been sent to builders, and we are waiting for the next block.

• bundle_failed: The bid was not included.

• bundle_success: The bid was included in chain, the auction was successful.

• released: The auction is done and no bid was successful.
