Descripción de la oferta

Satoshis Games is a high growth startup founded in 2018 with the goal of leading the application of decentralized technologies (mostly blockchain) to the gaming industry.

After developing the first gaming plataform with Bitcoin micropayments as a proof of concept in 2019 (, we began winning our first international hackathons and got our first funding rounds from US investors and crypto world celebrities to advance product development.

We've since developed Light Nite, a Battle Royale game featuring in-game cyrpto rewards and NFT skins. At the same time we started and launched Elixir, what is called to be the Steam of the crypto games. This product was again awarded with a Hackathon 1st prize and is focused on being the first platform with an SDK that allows safe distribution of crypto-games, minting and integration of NFTs in games and launching of new crypto-games to the market, which are currently banned from traditional game stores. We released an Alpha version in June '21 along with an NFT marketplace, won the 1st prize at Bitcoin 2021 startup contest in Miami, and is steeply growing in new pc and mobile crypto games to launch and distribute.

We're also currently developing our second game for mobile and desktop using Binance Smart Chain, and are ready to enter the decentralized finance (DeFi) scene with more exciting projects in the very near future. Satoshis Games has been selected by Binance as one of the 7 startups to participate at its "Most Valuable Builder" Accelerator Program.
