Ethereum Smart Contract

Smart contracts are the fundamental building blocks of Ethereum's application layer. They are computer programs stored on the blockchain that follow "if this then that" logic, and are guaranteed to execute according to the rules defined by its code, which cannot be changed once created.

Smart contracts allow secure and trusted transactions between anonymous parties without consulting a central authority.

The Listener allows you to listen for an event fired by an Ethereum Smart Contract.

The Action Agent allows you to fire Ethereum Smart Contract functions.
