Why BoltRPC

Built for teams that ship on zkSync.

Reliable RPC as the ZK ecosystem matures

zkSync Era's DeFi TVL is growing as more protocols deploy. Reliable infrastructure becomes more critical as the value of assets depending on your RPC increases. BoltRPC provides dedicated capacity with flat pricing that does not scale against you as your usage grows.

Native account abstraction multiplies RPC calls

zkSync Era has native account abstraction built into the protocol. AA-powered dApps generate more RPC calls per user interaction than standard EOA wallets: fee estimation for paymasters, validation calls, and signature verification all add up. BoltRPC handles the higher call volume without degradation.

ZK rollup infrastructure demands more from nodes

zkSync Era's proving pipeline means nodes process significant data alongside standard JSON-RPC requests. BoltRPC's infrastructure is sized for this load, not just for standard EVM traffic.

EVM-compatible tooling with minimal adjustments

zkSync Era is EVM-compatible. Most Ethereum code deploys with minor adjustments, and the same JSON-RPC methods apply. Teams migrating from Ethereum or other EVM chains can connect in minutes.

WebSocket for real-time zkSync events

Subscribe to account changes and new blocks via WebSocket. Essential for account abstraction wallets tracking session key states and paymaster events.

Full zkSync Era JSON-RPC surface

BoltRPC supports the complete zkSync Era JSON-RPC specification including all eth_* methods and zkSync-specific extensions like zks_getBlockDetails and zks_getTransactionDetails.
