ACCESSRPC that routes around failure.
One Base JSON-RPC endpoint across multiple HTTPS providers. KOVA failovers on rate limits, cools down sick endpoints, and never returns provider URLs to callers.

Explore API ONCHAIN INFRASTRUCTURE, SIMPLIFIED
The reliable edge
for onchain business.
KOVA is a Base-first gateway: resilient JSON-RPC, payer-bound USDC invoices, and Ed25519-signed webhooks — without holding customer keys.

/ ONE GATEWAY, THREE PRODUCTSEverything between your app
Everything between your app
and the chain.
Use the complete stack or start with one API. Every layer is designed to run lean, fail gracefully, and scale with actual usage.

OBSERVEInvoice events, delivered with a signature.
Register an allowlisted HTTPS callback. KOVA challenges ownership, then signs every invoice update with Ed25519. Redirects and private IPs are rejected.

SETTLEUSDC invoices without custody.
Create a payer-bound invoice for Circle’s canonical Base USDC. KOVA confirms the exact transfer and confirmation depth. Funds never enter a KOVA wallet.

No infrastructure maze.
Your shop creates a USDC invoice. KOVA routes the chain requests, catches the transfer, waits for finality, then calls your application. Four moving parts become one predictable workflow.
