Type-safe abstractions for interacting with Ethereum smart contracts

Interacting with a smart contract requires broadcasting carefully crafted transactions where the data field contains the function’s selector along with the arguments of the called function.

This module provides the Contract and ContractFactory abstractions so that you do not have to worry about that. It also provides typesafe bindings via the abigen macro and the Abigen builder.

Proc macro to generate type-safe bindings to a contract(s). This macro accepts one or more Ethereum contract ABI or a path. Note that relative paths are rooted in the crate’s root CARGO_MANIFEST_DIR. Environment variable interpolation is supported via $ prefix, like "$CARGO_MANIFEST_DIR/contracts/c.json"

Structs

Abigenabigen

Builder struct for generating type-safe bindings from a contract’s ABI

BaseContract

A reduced form of Contract which just takes the abi and produces ABI encoded data for its functions.

Contract

A Contract is an abstraction of an executable program on the Ethereum Blockchain. It has code (called byte code) as well as allocated long-term memory (called storage). Every deployed Contract has an address, which is used to connect to it so that it may be sent messages to call its methods.

ContractDeployer

Helper which manages the deployment transaction of a smart contract.

ContractFactory

To deploy a contract to the Ethereum network, a ContractFactory can be created which manages the Contract bytecode and Application Binary Interface (ABI), usually generated from the Solidity compiler.

LogMeta

Metadata inside a log

MultiAbigenabigen

Collects Abigen structs for a series of contracts, pending generation of the contract bindings.

Multicall

A Multicall is an abstraction for sending batched calls/transactions to the Ethereum blockchain. It stores an instance of the Multicall smart contract and the user provided list of transactions to be made.
