Crypto currencies and blockchain is the core of DeFi market where the investors and traders try to get opportunities of Crypto currencies price volatility in order to make profits. However, this volatility in the prices can lead to economic risk for the traders.

The purpose of this thesis is to design and implement a proof-of-concept for a bot-based trading system that works on the decentralized finance (DeFi) ecosystem on Binance Smart Chain, in order to gather the token pairs prices and take advantage from the trading strategies to place, sell and buy orders automatically. This system aims to give permission for the bot to be able to access the owner’stokens in Metamask digital wallet. Furthermore, it aims to make the bot able to run and interact with the users' wallet 24/7 regardless if the users are online or not.

The results of designing and implementing this proof-of-concept shows that the system meets the requirements. It is possible to build an automated trading system on the decentralized finance market. However, there are some financial and trust issues to be solved before it would be feasible launched on the market.
