DoodleCoin integrates advanced smart contract features, including liquidity pools and token scarcity mechanisms like burning or locking main wallet tokens. The DDM NFT store is a cornerstone, offering a marketplace for unique, collectible doodle characters that embody the project's black and white aesthetic and provide holders with benefits such as in-game utility, community governance, and exclusive access to features. This sets a stage for active community involvement and enhances the value of the NFTs within the ecosystem.

The DoodleCoin ecosystem also boasts Doodle Match, a Play-to-Earn game that uses Match-3 or puzzle mechanics to engage a broad audience. This game integrates NFTs as playable characters, adding personalization and strategy, and includes leaderboards and tournaments to encourage a competitive community spirit. The seamless swap system within DoodleCoin allows for easy exchange of DDM tokens with other cryptocurrencies, enhancing liquidity and facilitating user participation in a growing digital economy.
