Which blockchains does SwiftNodes support?
SwiftNodes provides RPC endpoints for 125+ chains including Ethereum, Solana, Base, BNB Smart Chain, Arbitrum, Optimism, Polygon, Avalanche, Linea, Scroll, zkSync, Polygon zkEVM, Cosmos, Polkadot, TRON, Sui, Aptos, and many more EVM and non-EVM networks. One API key works across all of them.
How does SwiftNodes pricing work?
SwiftNodes uses flat-rate monthly pricing with no per-request fees. Plans range from a free tier (2 HTTP req/s, capped at 250,000 requests/month) through Starter ($49/mo, 50 req/s), Growth ($89/mo, 150 req/s), Scale ($149/mo, 300 req/s), and Pro ($249/mo, 500 req/s). Paid plans have no monthly request cap — just the flat rate limit. Prepay 6 months for 5% off, or 1 year for 10% off.
Is KYC required to use SwiftNodes?
No. You can sign up with either an email (one-time PIN, no password) or a crypto wallet. We never ask for ID documents and we never store passwords.
How can I pay for a plan?
Paid plans accept either a credit or debit card, or cryptocurrency — ETH, BNB, USDT, and USDC on any supported chain. The free tier needs no payment method at all.
Does SwiftNodes support WebSocket RPC?
Yes. Every supported chain exposes both an HTTP endpoint (https://rpc.swiftnodes.io/rpc/<chain>) and a WebSocket endpoint (wss://rpc.swiftnodes.io/ws/<chain>) for real-time subscriptions and streaming.
Do paid plans include archive node access?
Yes. Archive node access is included on every paid plan for supported chains — there's no separate, more expensive 'archive tier' to upgrade to.
