JSON-RPC Reference

eth_sendRawTransactionSync

Submits a signed transaction and blocks until the transaction is included, returning the full transaction receipt instead of only the hash. Useful for low-latency flows such as flashblock confirmation. **Availability:** Not all Conduit networks expose this method. If you receive `-32601 method not found`, the network or endpoint does not support synchronous submission — use `eth_sendRawTransaction` and poll `eth_getTransactionReceipt` instead. **Timeout:** An optional `timeoutMs` parameter hints how long the server should wait for a receipt. The node may enforce a shorter configured maximum. ⚡ Compute Units: [200 CU](https://docs.conduit.xyz/rpc-nodes/information/compute-units)

logsBloomstringformat: "^0x[0-9a-fA-F]{512}$"
effectiveGasPricestringformat: "^0x(0|[1-9a-fA-F][0-9a-fA-F]*)$"

The actual value per gas deducted from the sender’s account. Before EIP-1559, this is equal to the transaction’s gas price. After, it is equal to baseFeePerGas + min(maxFeePerGas - baseFeePerGas, maxPriorityFeePerGas).

tostring or nullformat: "^0x[0-9a-fA-F]{40}$"
Address of the receiver or null in a contract creation transaction.
blobGasUsedstringformat: "^0x(0|[1-9a-fA-F][0-9a-fA-F]*)$"

The amount of blob gas used for this specific transaction. Only specified for blob transactions as defined by EIP-4844.

contractAddressstring or nullformat: "^0x[0-9a-fA-F]{40}$"
The contract address created, if the transaction was a contract creation, otherwise null.
rootstringformat: "^0x[0-9a-fA-F]{64}$"

The post-transaction state root. Only specified for transactions included before the Byzantium upgrade.

statusstringformat: "^0x(0|[1-9a-fA-F][0-9a-fA-F]*)$"

Either 1 (success) or 0 (failure). Only specified for transactions included after the Byzantium upgrade.

blobGasPricestringformat: "^0x(0|[1-9a-fA-F][0-9a-fA-F]*)$"

The actual value per gas deducted from the sender’s account for blob gas. Only specified for blob transactions as defined by EIP-4844.

OP-Stack only. L1 base fee at the time this transaction was posted, in wei.

l1FeeScalarstring

OP-Stack only. Scalar applied to L1 fee. Used by pre-Ecotone fee model; superseded by l1BaseFeeScalar / l1BlobBaseFeeScalar post-Ecotone.

l1BaseFeeScalarstringformat: "^0x(0|[1-9a-fA-F][0-9a-fA-F]*)$"

OP-Stack only. Post-Ecotone scalar applied to the L1 base fee component.
