MEV protection
Keep BNB Smart Chain mainnet transactions out of the public mempool with private routing to block builders. Reduce exposure to front-running and sandwich attacks through your existing endpoint.
Power swaps, trading bots, and onchain apps with reliable, high-performance BNB Smart Chain (BSC) RPC infrastructure.

Access BNB Smart Chain through a single, geo-balanced endpoint. Your requests automatically reach the nearest available region, with no manual region selection or extra setup.
Protect swaps, accelerate transaction propagation, and access historical BSC data with the tools your application needs.

Route BSC eth_sendRawTransaction calls through bloXroute’s distribution network for faster propagation. Keep your existing endpoint for pool reads, event monitoring, and transaction submission.
Run high-volume BSC reads, pool monitoring, and application traffic with unlimited requests within your RPS tier and predictable monthly costs.
Query BNB balances, BEP-20 contract storage, and historical pool state. Backfill event logs for DeFi analytics, strategy research, and financial reconciliation.
Replay BSC transactions with debug_traceTransaction to diagnose failed swaps and inspect internal calls. Dedicated Geth full nodes expose debug APIs; Reth archive nodes also support trace APIs.
Read pool prices with eth_call, follow swap events over WebSockets, and submit signed transactions. Choose MEV protection for private routing or Warp transactions for faster propagation.

Read articleBNB Smart Chain (BSC) uses an Ethereum-compatible JSON-RPC API. Connect through your Chainstack HTTPS endpoint to read BNB and BEP-20 balances, call smart contracts, retrieve event logs, estimate gas, and submit signed transactions. Common methods include eth_getBalance, eth_call, eth_getLogs, eth_estimateGas, and eth_sendRawTransaction. Use the WebSocket endpoint with eth_subscribe for supported real-time subscriptions.
Use ethers.js or viem for JavaScript and TypeScript, web3.py for Python, and Hardhat or Foundry for smart contract development. Configure the endpoint for the correct network: BSC mainnet uses chain ID 56, and testnet uses 97. See the BNB Smart Chain API reference and BNB Smart Chain tooling guide for integration examples.
