BNB Smart Chain RPC Endpoint

Flat-rate BNB Smart Chain RPC provider and BNB Smart Chain RPC node access: free tier, no KYC, HTTP & WebSocket. BNB Smart Chain mainnet chain ID 56.

BNB Smart Chain is a high-throughput EVM-compatible Layer 1 launched and operated by Binance. With sub-second block times and gas fees typically under a cent, BSC is a popular destination for retail DeFi, GameFi, and memecoin activity.

About BNB Smart Chain

BSC launched in September 2020 as a parallel chain to Binance Chain (now BNB Beacon Chain) to add EVM compatibility. It uses a Proof-of-Staked-Authority (PoSA) consensus with 41 active validators, producing a block roughly every 0.45 seconds (measured September 2026, over 10,000- and 100,000-block windows).

BSC is the second-largest EVM chain by daily transactions after Ethereum mainnet, driven by extremely low fees, PancakeSwap and other major DEXes, and a massive memecoin ecosystem. Smart contract semantics are identical to Ethereum — anything written for ETH compiles and deploys on BSC unchanged.

Common Use Cases on BNB Smart Chain

• Retail DeFi and yield farming (PancakeSwap, Venus)
• Memecoin and token launches
• GameFi and high-frequency dApps
• Cross-chain bridging origin/destination
• Stablecoin payments (BUSD legacy, USDT, USDC)

BNB Smart Chain Ecosystem

PancakeSwap is the dominant DEX. Other notable projects include Venus (lending), Trust Wallet, Biswap, and a deep memecoin scene. BSC processes consistently 3-5M transactions/day, more than most L2s combined.

Bridging to BNB Smart Chain

Use the official Binance Bridge or third-party bridges like Stargate, Multichain successors, and Squid for cross-chain transfers. Stablecoins typically use Wormhole or LayerZero variants.
