Common JSON-RPC calls

Chain ID:

curl -s https://rpc.khromosome.xyz \
  -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}'
# => {"jsonrpc":"2.0","id":1,"result":"0xbdb29"}

Latest block number:

curl -s https://rpc.khromosome.xyz \
  -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

Account balance (wei, hex):

curl -s https://rpc.khromosome.xyz \
  -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","method":"eth_getBalance","params":["0xYOUR_ADDRESS","latest"],"id":1}'

Gas price:

curl -s https://rpc.khromosome.xyz \
  -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","method":"eth_gasPrice","params":[],"id":1}'

Because the EVM is unmodified, the full standard eth_*, net_*, and web3_* method set is available, plus the explorer's ots_* (Otterscan) namespace for rich transaction tracing.
