Blockchain has received a lot of attention for multiple use cases and applications since the first works emerged about 15 years ago, with its use targeting cryptocurrencies. During this period, a wide variety of platforms (e.g. Ethereum, web3), tools, programming languages and other resources such as smart contracts were proposed. With the aim of better understanding the use of smart contracts in Blockchain-based systems, this article presents a systematic review of the literature on Blockchain application architectures that make use of smart contracts, applied in different areas. It is expected to bring together approaches for the design and implementation of smart contracts on the Blockchain.
