eth_sendRawTransaction

Send Transaction RPC Method

POST https://eth-rpc.kolibr.io/ Submits a signed transaction to the Kolibrio Order Flow service and rebroadcasts it to another source if required. Fully implements the standard Solana eth_sendRawTransaction RPC method.

Additional URL Query Parameters

Name	Description
allow_reverts (optional)	Controls whether transactions that might revert are submitted. Default is true. Set to false to prevent transactions that may fail, avoiding potential extra gas costs
validToBlock (optional)	The block number as a string in hexadecimal format or number, indicating the maximum block until which the transaction will be rebroadcast and remain valid. By default, Kolibrio sets this to the subsequent 6 blocks. This parameter can be adjusted to extend or reduce the validity period as needed.

API KEY

Name

Description

api_key (optional)

Required for authentication, revenue distribution, and tracking. Including this key ensures that any generated revenue is attributed to the correct account. If not specified, the transaction will still be processed, but revenue will not be distributed. Can be passed as an x-api-key header or as an api_key query parameter in the URL. To obtain an api key, users must contact the Kolibrio team directly.
