The Problem It Solves

EaseNow addresses several key challenges faced by users wanting to make on-chain purchases but hindered by the complexities and limitations of current systems:

1. Lack of Immediate Funds: Users often need to buy extra tokens from centralized exchanges if they lack enough funds for a purchase.
2. Cold Wallet Transfers: Many users keep their tokens in cold wallets, requiring inconvenient transfers to hot wallets for transactions.
3. Insufficient Funds for Transaction Fees: Even with exact tokens for a purchase, users might not have enough left for transaction fees.
4. Delayed Salaries: Users may need to make a purchase but lack on-chain funds, especially when awaiting salary credits.
5. Centralized Exchange Dependence: Users accustomed to centralized exchanges may find on-chain shopping cumbersome and unfamiliar

How EaseNow Makes It Easier

EaseNow is designed to provide a smooth and hassle-free on-chain shopping experience by addressing the above problems:

• Pay Later Flexibility: Users can purchase items without immediate on-chain funds or transaction fees. EaseNow allows deferred payments, eliminating the need for immediate token availability.
• Non-Locking Collateral: EaseNow uses Real World Assets (RWA) as collateral in a non-locking manner, simplifying the onboarding process without locking users' on-chain assets.
• Credit Score Integration: Utilizing a Trusted Execution Environment (TEE), EaseNow assesses user credit scores from various third-party sources. Based on this score, users are granted appropriate credit on-chain.
• Identity Verification: To participate, users must verify their identity through personal documents and facial verification, sent securely to the TEE. This information is encrypted and stored on IPFS, ensuring confidentiality.
• Lender Security: While not collateralizing on-chain assets, EaseNow ensures lender security through DeFi mechanisms that support the pay

Challenges I ran into

Building the TEE in Golang was a challenging task. Fortunately, a library called Ego simplified the process. Additionally, since it was my first time using Golang to interact with EVM chains, there was a learning curve involved. I had to create a pipeline from Hardhat to Golang to utilize the latest ABI and scaffold code for easy on-chain execution and queries. Integrating Coinbase Smart Wallet and implementing ERC-1271 proved to be particularly tricky.
