STEPN, the world’s first move-to-earn game, was launched in late 2021 by FindSatoshi Lab. Running on Ethereum’s biggest competitor Solana, STEPN has low gas fees and carbon footprint.  Players can try the game mechanics for free, but to start earning native tokens GST and GMT, one must buy NFT sneakers with varying stats determining their value. The more one moves, the more they earn. Sneakers can also be traded on NFT marketplaces.
