On the Ethereum platform, some smart contracts represent and manage tokens. The Dai token contract, for instance, manages the accounting for external Dai balances and issues approvals for transfers. Like many other tokens on Ethereum, Dai was created according to a widely-accepted standard called ERC-20. WPSmartContracts is an easy way to deploy and manage Ethereum and xDai Smart Contracts from WordPress.. Our version 1.1 was a successful Proof of Concept that allowed end-users to deploy ERC-20 Standard and Advanced Tokens, Crowdfundings, and Initial Coin Offerings (ICOs).

An Ethereum smart contract is bytecode deployed on the Ethereum blockchain. There could be several functions in a contract. An ABI is necessary so that you can specify which function in the The EVM, in turn is the part of the Ethereum protocol that actually runs the code in Smart Contracts and determines their outputs. So if you wanted to run an Ethereum node in Python, Pyethereum is a good place to start. Ethereum Real Estate Contracts Are Flexible There is no limit to the number of contingencies a smart contract may include. An Ethereum real estate contract may be written so that any number of final sales prices, reductions in price, or increases, can be triggered based on specific events agreed to by the parties.
