Gacha Galaxy

Certified value for graded cards on Robinhood Chain. Gacha Galaxy prices PSA-graded cards privately, publishes a price certificate onchain that anyone can check, and lets you borrow against the card at 50% loan to value. Same model as Stock Tokens, new asset.

Sự miêu tả

Graded trading cards are a $1B+ asset class with no liquid way to borrow against them. Gacha Galaxy fixes that on Robinhood Chain. How it works: 1. A private pricing engine values each PSA-graded card from real sales data (example: Rayquaza VMAX #218, PSA cert 109308847, $2,900, confidence 86, risk tier A, 20 price points). 2. The price certificate is written onchain to the AppraisalRegistry, so anyone can verify it. 3. The card is tokenized as a GradedCard and deposited into the CardLendingVault. 4. The owner borrows up to 50% loan to value against a conservative floor. Example: $2,587 floor, $1,293 max loan, liquidation line $1,552. In the demo we borrow $1,000. Same model as Stock Tokens, new asset class. Live on Robinhood Chain testnet now, moving to mainnet at the end of this month. We do not use Robinhood's tokens and are not a Robinhood partner.

Tiến độ hackathon

Built and deployed AppraisalRegistry, GradedCard (v2), CardLendingVault (v2) and a test dollar on Robinhood Chain testnet. Connected the private pricing engine to the chain with a bridge, built the live web app, and completed full deposit and borrow flows onchain, including a $25 test loan and a $1,000 demo loan.
