CryptoWave

Addressing current challenges in crypto adoption, our team has developed a Webapp to streamline payments using cryptocurrencies through innovative solutions. We recognize the concerns around initial gas fees, KYC processes, and the complexity of onboarding with seed phrases.

To tackle these issues, our Webapp introduces a unique approach. We've implemented a voucher system and NFC payments to eliminate the burden of gas fees for users receiving payments. Internally, we handle gas deductions, ensuring a seamless experience for both parties involved.

Security is a top priority. We've incorporated spending limits for NFC cards to mitigate the risk associated with traditional wallets. This ensures that the entire wallet balance is never exposed, providing users with enhanced peace of mind.

Our system operates on a paychain (base chain) model, streamlining the payment process on behalf of users. To enhance user accessibility, we support web3auth as a sign-in provider. This allows individuals unfamiliar with seed phrases or cryptographic keys to leverage their existing email accounts for creating crypto wallets.

In summary, our Webapp addresses key challenges in crypto adoption, offering a user-friendly and secure platform for crypto payments through vouchers and NFC technology.

Also inconsistent blockscan providers made it hard to verify contracts on each chain even with foundry
