描述
Paytree lets a user lock tokenized stock and spend dollars without selling it. The stock stays in the vault as collateral. A funded USDG pool covers the spend. The allowance is 5% of the locked value, so $10,000 of stock opens a $500 paycheck. Spending records a debt. Repaying clears it, and only then can the user withdraw the stock.
It is live on Robinhood Chain testnet, chain ID 46630. The app is at https://paytree-blush.vercel.app and the code is at https://github.com/cipherEncrypt/paytree. Vault: 0x93132433013E92F18F7850B80C4cB31Cd578B048. Testnet uses mock stock and mock USDG. Production would use Robinhood stock tokens and Paxos USDG.
本次黑客松进展
Built the product during this buildathon. Wrote PaytreeVault, MockStock, and MockUSDG, with deposit, allowance, spend, repay, and withdraw. Allowance is fixed at 5%. Added tests for the full flow, overspend, and withdraw-while-in-debt. Deployed to Robinhood Chain testnet and seeded the USDG pool. Shipped a wallet app that reads balances from the contracts and sends real transactions. Recorded a demo of lock, spend, and repay.
融资状态
No funding yet. This is an early testnet product, built for the buildathon. Not raising right now. Next step is a mainnet version on Robinhood Chain with real stock tokens and Paxos USDG, then a small user pilot.
