timeboost_sendExpressLaneTransaction
Submit priority transactions through Arbitrum express lanes for faster processing using the timeboost API.
Instructions
Submit priority transactions through express lanes for faster processing (requires timeboost API)
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| rpcUrl | No | The RPC URL of the Arbitrum node (optional if default is set) | |
| chainName | No | Chain name (e.g., 'Xai', 'Arbitrum One') - will auto-resolve to RPC URL | |
| submission | Yes | Express lane submission data |
Implementation Reference
- src/index.ts:684-700 (handler)MCP tool handler implementation that resolves the RPC URL using chainLookupService if needed, instantiates NitroNodeClient, calls sendExpressLaneTransaction with the provided submission, and returns the JSON-stringified result.
case "timeboost_sendExpressLaneTransaction": { const rpcUrl = await this.resolveRpcUrl( (args.rpcUrl as string) || (args.chainName as string) ); const nodeClient = new NitroNodeClient(rpcUrl); const result = await nodeClient.sendExpressLaneTransaction( args.submission ); return { content: [ { type: "text", text: JSON.stringify(result, null, 2), }, ], }; } - src/index.ts:1506-1529 (schema)Tool schema definition including name, description, and inputSchema specifying required 'submission' object and optional rpcUrl/chainName parameters. This is returned by getAvailableTools().

async sendExpressLaneTransaction( submission: any ): Promise<{ success: boolean; error?: string }> { try { await this.makeRpcCall("timeboost_sendExpressLaneTransaction", [ submission, ]); return { success: true }; } catch (error) { return { success: false, error: `Express lane transaction not supported on this RPC endpoint: ${ (error as Error).message }`, }; } }
