The fastest path to the Base sequencer.
Every transaction rides the same fast inclusion path, free tier or paid. The tiers differ in data access, not speed.
Plans
Free
For wallets and developers. No key, no signup, no billing.
- Fast inclusion and a smaller sandwich window, hand-tuned for Base
- All standard eth_*, net_*, web3_* methods
- 100 req/s per IP, batches up to 50, 5,000-block eth_getLogs
- No logs: no IPs, no bodies, no headers, no cookies
- Community support, email us
Edge
For trading desks. Everything in Free, plus the data that pays for itself on the first recovered fill.
Limited seats, by application, we qualify on a short call.
See Edge- Pre-confirmation Flashblocks feed (early access)
- Live transaction & log stream (early access)
- Custom revm engine (early access)
- eth_getLogs: 100,000 blocks per call (20× public)
When do I need a key?
Sustained > 100 req/s, eth_getLogs beyond 5,000 blocks, or you need debug_* / trace_*. A request is one JSON-RPC call, a batch of 50 counts as 50.
Free key
for production apps · still $0Outgrowing the anonymous defaults but not a trading desk? Ask for a free key, issued by hand, higher limits, your IP still never logged.
by request, hand-issued
Every tier rides the same engine: the same fast inclusion and the same tuning, anonymous through Edge.

Azul’s p50 is measured live from its own /public-stats; every other latency is a published estimate from US East, rounded. Competitor rate-limit numbers are from published docs as of 2026-05; subject to change. We do not audit third-party providers, verify current policy before relying on it.
One region, tuned by hand, and we say so.
Everything above runs from us-east-1 (Virginia). It is fastest from US-East, not a global anycast SLA. If your fleet needs multi-region or a signed SLA, that’s an Edge conversation.
