RPC for Wallets & Frontends
A wallet or dapp frontend that falls back to a flaky public RPC shows users failed balances and stuck transactions. Public endpoints often end up in a frontend's fallback list via chainlist — quietly rate-limiting your users mid-session.
Where public RPC falls short
- Public RPCs in your fallback path rate-limit mid-session, so users see failed balance loads and pending sends.
- Managing a different provider per chain is operational overhead.
- A single upstream failing takes your whole frontend's reads down.
How NodeFlare handles it
One key, all chains
A single endpoint pattern across all 22 chains — just swap the chain slug.
Automatic failover
Multi-region nodes with failover keep balances, reads, and sends reliable.
Drop-in replacement
Same JSON-RPC URL shape as a public endpoint — a one-line swap for the fallback you're already on.

FAQ
Can I use NodeFlare directly in the browser?
The public endpoint is CORS-enabled for browser use. For keyed requests, route them through your backend (keyed endpoints aren't CORS-open, to keep your key private).
Is one key enough for a multi-chain wallet?
Yes — one key works across all 22 chains; you only change the chain slug in the URL.
Is there a free tier for wallets?
Yes — 2,000,000 compute units per month, no credit card. Higher plans add rate limit and CU headroom as you grow.
Free key, first call in under a minute
Every chain, multi-region failover, no throttling — no credit card.
