| Name | Description |
|---|---|
rev_recv (required) | The address that will receive arbitrage payments in SOL. |
tx_broadcast_mode (optional) | The method used to broadcast the target transaction. Available options:
|
frontrun_protection (optional) | boolean(false by default)Enables adaptive leader filtering. Transactions are routed away from slot leaders flagged for malicious ordering and preferentially sent to low-risk leaders. If the current or next leader is assessed as high risk, submission may be delayed or skipped. This feature operates on a best-effort basis without guarantees, while meaningfully reducing the likelihood of toxic frontrunning. |
delay_ms (optional) | integer(50 by default)Maximum time (in milliseconds) Kolibrio may wait to find and land an arbitrage trade before submitting the original transaction to the current leader. |

| Name | Type | Description |
|---|---|---|
| backrun_exist | bool | Indicates whether any backrun transactions have been landed |
| backrun_signature | string | A signature of landed backrun transaction |
| revshare_info. revshare_signature | string | A signature of the on-chain transaction that executes the revenue split across participating parties |
| revshare_info. total_arbitrage_revenue_lamports | number | The total revenue extracted from an arbitrage opportunity (in lamports) |
| revshare_info. jito_tip_lamports | number | The amount paid to Jito for bundle inclusion (in lamports) |
| revshare_info. kolibrio_tip_lamports | number | Kolibrio fee (in lamports) |
| revshare_info. originator_tip_lamports | object | A mapping of Solana addresses to the lamport amounts paid to each originator partner. These recipients are determined by the rev_recv setting in the RPC request or through custom configuration. |
| Name | Description |
|---|---|
allow_reverts(optional) | Controls whether transactions that might revert are submitted. Default is false to prevent transactions that may fail, avoiding potential extra gas costs Set to true to allow pontetially reverted transactions to land onchain. |
skip_preflight(optional) | Controls whether Kolibrio simulates validation checks (nonce, balance, gas limit) before submission. Default false — returns standard RPC errors on invalid transactions. Set true to skip checks and always receive a transaction hash result. |
| 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. |

Specifies an array of trusted builders for transaction inclusion. Defaults are \[titan, beaver, rsync, flashbots].
You can add additional options: \[jetbuilder, builder0x69, penguin, payload].
