One key for 24 chains, flat request-unit pricing, and failover you never notice. In production since 2021, ISO 27001 certified.
2-week trial · no credit card · API key in under 60 seconds
Keys you can lock down, usage you can see, and costs that never surprise you. All self-serve, right from the dashboard.
Scope every key to chains, IP ranges, origins and methods. Set its own rate limit and daily cap. Rotate it with a grace period, so deploys never break.
Explore access control →Every method has a published request-unit weight, so you can estimate costs before you ship. Alerts at every threshold, a forecast of your run rate, and an overage cap you set yourself.
Get every new block, transaction verdict or address transfer as a signed webhook. Confirmed and reorg-aware, with retries and a delivery log per attempt. No polling loops to babysit.
Explore webhooks →Point your client at one URL and swap the chain slug. Standard JSON-RPC 2.0, so ethers, viem, web3.py and Foundry work unchanged. No SDK, no per-chain billing.
Browse all 24 networks →// connect to Ethereum
const eth = new ethers.JsonRpcProvider(

);
// same key, different chain
const base = new ethers.JsonRpcProvider(
'https://endpoints.boltrpc.io/rpc/KEY/base'
);Plumbing you stop thinking about, run by the team that keeps Chainlink oracle nodes online.
Requests reroute across regions in under a second. WebSocket subscriptions survive the switch with no gaps and no duplicate events.
Historical queries go to archive nodes, trace calls to nodes that support them, finalized reads to nodes that are caught up. Automatically.
External probes hit every chain each minute, and on-call engineers respond 24/7. Every deploy is smoke-tested across all networks.
No compute-unit surprises, no per-second caps inside your quota. Pay by card or crypto, cancel anytime.
Yearly billing saves 17% · 2-week free trial, no credit card
