A BNB Smart Chain RPC endpoint is a URL your application uses to communicate with a BSC node. It lets you read balances, call smart contracts, retrieve event logs, estimate gas, and submit signed transactions through an Ethereum-compatible JSON-RPC API.
Create a Chainstack account and a project, then deploy a BNB Smart Chain node on mainnet or testnet. Open Access and credentials and copy your HTTPS endpoint. Add this URL to your wallet, SDK, or development framework. Use the WebSocket endpoint when your application needs supported subscriptions.
Yes. The Chainstack Developer plan includes 3 million request units per month, an overall limit of 25 requests per second, one node, and WebSocket access. No credit card is required. Individual methods may have additional limits. Mainnet transactions still require BNB for gas.
BNB Smart Chain mainnet uses chain ID 56, or 0x38 in hexadecimal. Testnet uses chain ID 97, or 0x61. Mainnet uses BNB for gas, while testnet uses test BNB. Your endpoint and chain ID must refer to the same network.
Yes. Add or edit BNB Smart Chain in MetaMask and enter your Chainstack HTTPS RPC URL. For mainnet, use chain ID 56 and the currency symbol BNB. For testnet, use chain ID 97. Keep your endpoint credentials private.
Yes. Chainstack provides BNB Smart Chain WebSocket endpoints for supported subscriptions, including new blocks and smart contract event logs. Use the WebSocket URL from your node’s Access and credentials section with eth_subscribe. WebSocket access is included in the Developer plan.
Global Nodes provide managed, geo-balanced RPC access with automatic routing. Dedicated Nodes reserve infrastructure for your workload and offer deployment-specific configuration options. Choose according to resource isolation, configuration, and workload requirements. Dedicated infrastructure is billed separately from the subscription plan.
A BSC archive node provides historical account and smart contract state. Use it to query past balances, contract storage, and contract calls for analytics, backtesting, and reconciliation. Chainstack archive access is available starting from the Growth plan. Archive access does not mean unlimited request usage.
Yes. Debug & Trace APIs are available on BNB Smart Chain Global Nodes on paid plans. Dedicated full nodes running BSC Geth expose debug methods, while Reth archive nodes also expose trace methods. Availability depends on your node configuration and the historical state required by the request.
Yes. MEV protection is available on BNB Smart Chain mainnet Global Nodes on every plan, including Developer. It uses private routing to reduce exposure to front-running, sandwich attacks, and other MEV risks. Enable the add-on on your node. It does not guarantee inclusion or eliminate every MEV risk.
Warp transactions route BSC eth_sendRawTransaction submissions through bloXroute’s distribution network for faster propagation. Other RPC methods continue through Chainstack. Warp transactions are available on paid plans and consumed transactions are billed separately. This is a different routing option from MEV protection.
Yes. The Unlimited Node add-on provides unlimited RPC requests within your selected requests-per-second tier for a fixed monthly add-on fee. It is available starting from the Growth plan. Your subscription, Dedicated Node infrastructure, and other add-ons are billed separately.
Yes. Chainstack Self-Hosted supports BNB Smart Chain mainnet and testnet deployments on infrastructure you control. The Community edition is free, and you pay for your own servers or cloud resources. Follow the installation guide to set up your deployment.
Open the Chainstack BNB Smart Chain testnet faucet, enter your wallet address and Chainstack API key, and submit a claim. The faucet tops eligible wallets up to 0.5 testnet BNB every 24 hours. Use testnet BNB to pay gas for smart-contract deployments and test transactions through your BSC testnet RPC endpoint. Wallet eligibility requirements are listed on the faucet page.
BNB 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, và 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. Xem BNB Smart Chain API reference và BNB Smart Chain tooling guide for integration examples.
