Plant2Earn is a Defense strategy game built on the Binance Smart Chain platform.
Once upon a time, the Plant spirits lived happily in the garden of EDEN, until one day a treacherous Plant spirit opened the door of the demon world, allowing Youkai to invade the garden of EDEN. To protect the land of EDEN, the Plant Warriors must gather together to build defensive walls against the invasion of Youkai.
Planting Warrior from Seed, battling invading Youkai, collecting solar energy, and earning P2E tokens are indeed part of the game. Players can engage in EDEN Garden and obtain P2E tokens by battling Youkai with their Plant Warrior NFT assets. Player-owned NFTs issued to the ERC-721 standard that can be exchanged on the Plant2Earn marketplace
