Quick Start

Basic Example

const url = "http://ny.flashblock.trade/api/v2/submit-batch";

const response = await axios.post(
    url,
    {
        transactions: [...base64Transactions],
    },
    {
        headers: {
            'Content-Type': 'application/json',
            Authorization: 'YOUR_API_KEY',
        },
    },
);

Advanced Example

const body = {
    id: 1,
    jsonrpc: "2.0",
    method: "sendBundle",
    params: [
        [...base64Transactions],
        {
            encoding: "base64",
        }
    ],
    mev: false,
};

Best Practices

1. Error Handling: Always implement appropriate error handling mechanisms
2. Retry Strategy: Use exponential backoff retry strategies
3. Monitoring: Monitor transaction status and error rates
4. Optimization: Adjust priority fees based on network conditions
