🏄🏽♂️ Best Use Case of Unlimit Crypto ⸺ $10,000
Up to 4 teams will receive $2,500
Inspiration:
Imagine the power of AA wallets with their smart contract execution functionalities. Now, pair that with Unlimit's capability to onramp into any cryptocurrency from any fiat currency or vice versa for offramps. An example could be a dapp where users utilize Unlimit's onramps to acquire a specific token, and upon receipt in their AA wallet, a predefined logic they created and manage initiates an NFT purchase. But that's just one example. The real magic lies in bridging the DeFi/Web3 Gaming/NFT world with the traditional banking/fiat realm through your innovative, “non-custodial dapp”. The possibilities are endless.
Qualification Requirements
Develop an app that seamlessly integrates Unlimit’s on/off ramps with combinations of the following:
-Account Abstraction Wallets (AA wallets)
-Dapps from the DeFi/NFT/Gaming/Web3 ecosystem
-Integration with web2 technologies to expand utility and accessibility
