Blockchain Developer


Lisbon, Portugal

AppCoins, as a project developed by Aptoide, aims to revolutionise app economy with the currency for App Stores.

The app economy has three main inefficiencies which are (1) lack of transparency or trust, (2) advertising inefficiency, (3) costly and inaccessible in-app purchases. AppCoins is the solution. It is an open and distributed protocol for app stores based on the Ethereum blockchain, using the ERC20 standard. It proposes to move the following three critical flows to the blockchain: advertising, in-app billing, and app approvals to allow transactions to occur through a blockchain-supported cryptocurrency in a decentralised, neutral and open system.

We are looking for a Software Developer to work in a multi-functional team dedicated to the AppCoins project. The challenge is ambitious, large-scale and provides almost unlimited opportunities for personal and professional growth.
