ethereum-abi

Fully-tested, lightweight Ethereum ABI encoder/decoder (ethereumjs-abi comes to 500k+ in browserify)

Currently supports:

• all uint/int types
• string
• bytes
• bool

To do:

• Fixed-size arrays
• Dynamic arrays of all types

Usage

const abi = require("ethereum-abi");

• Get a method signature

abi.methodID("test", [ "uint" ]);

• Encode arguments

abi.rawEncode([ "uint", "int32" ], [ 12, 300 ]);

• Decode arguments

abi.rawDecode([ "int64" ], Buffer.from("ffffffffffffffffffffffffffffffffffffffffffffffffffffb29c26f344fe", "hex"));
