Bitcoin Cash

Endpoint	https://rpc.lab.au.ro/bch
Protocol	BCHN JSON-RPC over HTTPS (POST)
Network	mainnet

Bitcoin Cash Node (BCHN) keeps the bitcoind RPC dialect — the Bitcoin page patterns apply with the /bch path, with the differences below.

Quick test

curl -X POST https://rpc.lab.au.ro/bch \
  -H "apikey: $YOUR_API_KEY" -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"1.0","id":1,"method":"getblockchaininfo","params":[]}'
# {"result":{"chain":"main","blocks":955006,...},"id":1}

BCHN differences (live-verified)

• estimatesmartfee does not exist — BCHN removed it. Use estimatefee (no arguments, returns BCH/kB), and remember BCH blocks are rarely full; 1 sat/byte usually confirms next block.
• Addresses use CashAddr format (bitcoincash:q...). Libraries: @psf/bch-js or bitcore-lib-cash handle CashAddr + signing; the broadcast path is the same sendrawtransaction.

Limitations

Same family limits as Bitcoin; plus the estimatesmartfee gap above.
