Collection Handbook is a very unique system that allows players to collect specific NFTs on different blockchains as collectibles to earn benefits in the game without pledging.
For instance, you will get a +30% ATK buff in the Godland if you have a CryptoPunk in your Ethereum wallet. You don't have to send your precious NFT to any address or pledging it to any smart contract, reducing unnecessary gas fee and more importantly keeping your assets safe.
Collection Handbook is based on a completely original system that we called Non-pledge Cross-chain Mechanism.
More details will be revealed as the game processes.
