Solana Smart RPC

Intelligent transport layer for Solana RPCs that handles load balancing, rate limit throttling, failover, fanouts, and retries. Built on top of @solana/web3.js.

Example Usage

import { TransportManager, TransportConfig } from '@nftechie/smart-rpc';

let transports: TransportConfig[] = [
    {
        rate_limit: 50,
        weight: 50,
        blacklist: [],
        url: 'https://bold-winter-brook.solana-mainnet.quiknode.pro/039710b0695699c8b2849d5903a9735260339476/',
        enable_smart_disable: false,
        enable_failover: false,
        max_retries: 0,
    },
    {
        rate_limit: 50,
        weight: 50,
        blacklist: ['getTokenLargestAccounts'],
        url: 'https://api.mainnet-beta.solana.com',
        enable_smart_disable: true,
        enable_failover: true,
        max_retries: 0,
    }
];

const transportManager = new TransportManager(transports);
const smartConnection = transportManager.smartConnection;

const resp = await smartConnection.getLatestBlockhash();
console.log(resp.blockhash.toString());
