9 providers. One SDK.
Every capability mapped.
chainkit routes between providers per-operation. Pick the operations your app needs — the
matrix below shows which providers cover them, so you can plan a routing policy that tolerates
any one of them going down. Generated from the SDK on 2026-05-22 (c3fd1b1).

Why this matters
Plan the routing policy from the matrix.
If your app calls GetBalance and PushTx, pick three providers
that both support both — that's your fallback chain. chainkit's routing engine handles the
rest: priority order, retries, scoring, circuit breakers.
For the truly curious
The data behind this page.
Every row is generated at build time from the SDK's own GetCapabilities() reflection. The drift check in CI fails if this page falls behind a new SDK release, so what
you see here is always what the SDK actually does.
