kh read

Read a smart contract view function

Synopsis

Call a read-only smart contract function via eth_call.

The function signature should be in Solidity format (e.g. "balanceOf(address)"). Arguments are positional and must match the function signature types.

Supported argument types: address, uint256, bool, bytes32.

No auth required. The RPC endpoint is yours to supply, via --rpc-url, the KH_RPC_URL env var, or an rpc. entry in the config file.

kh read <contract-address> <function-signature> [args...] [flags]

Examples

  # Read USDT total supply
  kh read 0xdAC17F958D2ee523a2206206994597C96e3cFa0e "totalSupply()" --chain 1

  kh read 0x6B175474E89094C44Da98b954EedeAC495271d0F "balanceOf(address)" 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 --chain 1

  # Read token decimals
  kh read 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 "decimals()" --chain 1

  # Use a custom RPC endpoint
  kh read 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 "decimals()" --chain 1 --rpc-url https://eth.llamarpc.com
