The problem indiefi.xyz solves

Pain: Idle Revenue, Zero Yield and DeFi Complexity Wall

Money stuck in the payment processor

• Stripe balance earns 0 % while founders pay cloud bills
• Lost opportunity: even 3% APY on recurring revenue compounds fast

Too many clicks and contracts

• Swap tokens, approve vault, sign transactions, track gas
• Moving funds manually to DeFi takes hours per month
• Founders prefer shipping features, not learning Solidity

Solution: AI chat-based assistant that generates yield on autopilot

Higher conversion and passive yield with zero extra effort

• After each sale, a user-defined % is sent to curated ERC-4626 vaults
• Revenue earns while they sleep → extended runway
• All in a clean dashboard and chat-based assistant “Ginga”

Challenges we ran into

The first hurdle was unifying Web two authentication with wallet based identity (inside Supabase).

Supabase expects a user id while MetaMask only proves address ownership. I solved this by signing a nonce, verifying it in an edge function, then minting a Supabase session tied to the wallet address.

A second challenge was the lack of testnet yield. Aave on Sepolia gives near zero interest, so I mocked an annual rate through Chainlink Functions and updated values hourly, which let the demo show realistic growth without mainnet gas costs.

Finally, aligning the correct token contract for each strategy was confusing because Aave accepts only its testnet USDC and WETH addresses. Mismatched tokens caused silent reverts. I solved this by storing the precise token address in the vault metadata and validating the asset before signing any transaction.
