Kyvro Developer Platform

Build on Kyvro

SVM-compatible infrastructure for applications, markets and autonomous agents. Standard Solana JSON-RPC, standard tooling and 0.4-second slots with fast finality.

Connect to Kyvro Testnet

Everything below comes from the canonical network configuration.

Network name: Kyvro Testnet
CAIP-2: solana:A8qzbNkAdT1GsqmyKTifWnTgS7Puqqmn
Genesis hash: A8qzbNkAdT1GsqmyKTifWnTgS7PuqqmniwdsGeaPc5Jo
Native token: tKYV · 9 decimals
HTTP RPC: https://rpc-testnet.kyvro.si
WebSocket RPC: wss://rpc-testnet.kyvro.si
Block explorer: https://explorer-testnet.kyvro.si

Verify before you trust

A wrong RPC URL looks exactly like the real network until you check. Compare getGenesisHash against the canonical value before sending value.

Quickstart

Connect and read the current slot.

import { Connection, clusterApiUrl } from "@solana/web3.js";

const connection = new Connection("https://rpc-testnet.kyvro.si", "confirmed");
console.log("slot:", await connection.getSlot());
console.log("genesis:", await connection.getGenesisHash());
// Expected genesis: A8qzbNkAdT1GsqmyKTifWnTgS7PuqqmniwdsGeaPc5Jo

Common requests

Copy, paste, and run against the public endpoint.

Current slot

curl -s https://rpc-testnet.kyvro.si -H 'content-type: application/json' -d '{"jsonrpc":"2.0","id":1,"method":"getSlot","params":[]}'

Account balance

curl -s https://rpc-testnet.kyvro.si -H 'content-type: application/json' -d '{"jsonrpc":"2.0","id":1,"method":"getBalance","params":["<PUBKEY>"]}'

Block with parsed transactions

curl -s https://rpc-testnet.kyvro.si -H 'content-type: application/json' -d '{"jsonrpc":"2.0","id":1,"method":"getBlock","params":[<SLOT>,{"encoding":"jsonParsed","maxSupportedTransactionVersion":0}]}'

Public endpoint limits

Enforced by the RPC gateway in front of dedicated RPC nodes. Validators are never exposed.

Methods: standard read methods (getSlot, getBlock, getTransaction, getAccountInfo, token and stake methods), sendTransaction, simulateTransaction and requestAirdrop. Node-admin methods are not available.
Batches: at most 50 requests per batch; request bodies up to 512 KB.
History windows: getSignaturesForAddress returns at most 1,000 signatures per request; getBlocks spans at most 500 slots.
WebSocket subscriptions: account, block, logs, program, root, signature, slot, slotsUpdates and vote subscriptions; up to 10 connections per IP and 50 messages per second per connection.

Rate limits: requests are weighted by cost (for example getSlot = 1, getBlock = 5, getProgramAccounts = 10). Anonymous callers get 50 units per second and 1,000,000 units per UTC day per IP. Exceeding a limit returns JSON-RPC error -32005.
API keys: for higher limits, keys are issued on request to projects building on Kyvro. Pass a key in the path (https://rpc-testnet.kyvro.si/v1/<key>) or in the x-api-key header. Keys can be restricted to origins, IPs and methods.

Kyvro Testnet is a development network

It may be reset. Do not rely on its state for anything of value. tKYV has no monetary value. Transactions are viewable at explorer-testnet.kyvro.si .
