Bitlayer RPC Endpoint

Flat-rate Bitlayer RPC provider and Bitlayer RPC node access: free tier, no KYC, HTTP & WebSocket. Bitlayer mainnet chain ID 200901.

Bitlayer is a Bitcoin layer 2 with an EVM-compatible execution layer, using BTC (with 18-decimal precision) as its gas token. Its live network is Bitlayer PoS (V1), while a BitVM-based rollup (V2) is under development.

About Bitlayer

Bitlayer PoS (Mainnet-V1) launched in early April 2024, alongside the project's technical white paper. Bitlayer shipped a BitVM bridge to mainnet beta in July 2025, but disabled bridge-in on May 28, 2026 and gave YBTC holders until June 3, 2026 to bridge back; no relaunch has been announced. The chain itself continues to produce blocks.

Bitlayer is EVM-compatible, so Solidity contracts and standard Ethereum JSON-RPC tooling work. BTC on Bitlayer uses 18 decimals rather than Bitcoin's 8, and the network enforces a minimum priority fee of 0.025 gwei; use eth_gasPrice or eth_maxPriorityFeePerGas to estimate fees. BTR is the project's separate token.

Common Use Cases on Bitlayer

• BTC-denominated DeFi
• Deploying existing EVM contracts with BTC gas
• Bitcoin asset indexing and wallets
• Testing BitVM-related applications
