Reference

JSON-RPC reference

REST API reference

The block explorer's own HTTP API. Lightweight JSON endpoints for stats, blocks, transactions, addresses, validators.

Smart contracts

Hardhat and Foundry configs, deployment notes, and KXCO-specific quirks (negligible gas, finality, allowlist).

Connect in 60 seconds

# Verify you can reach the network
curl -s -X POST https://chain.kxco.ai/rpc \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}'
# → {"jsonrpc":"2.0","id":1,"result":"0x10F447"}   (0x10F447 = 1111111)

# Latest block
curl -s https://chain.kxco.ai/api/stats
# → {"blockNumber":106500,"avgBlockTime":"5.0"}

Only the observer node is publicly reachable. Validator RPC ports are restricted to the internal network. Read-only methods work for everyone; writes require a funded account on a permissioned chain.
