EXAMPLES

  1. Call a function on a contract:

    cast call 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 \
  "balanceOf(address)(uint256)" 0x...

  2. Decode raw calldata:

    cast --calldata-decode "transfer(address,uint256)" \
  0xa9059cbb000000000000000000000000e78388b4ce79068e89bf8aa7f218ef6b9ab0e9d0000000000000000000000000000000000000000000000000008a8e4b1a3d8000
