Greenback lets anyone launch a memecoin that is economically tied to real Robinhood stock tokens (TSLA, NVDA, AMD, COIN, GOOGL, and more) on Robinhood Chain — one stock, an Absorb shield on that stock, a small basket of stocks, or Direct (no-feed names like BA locked into a Uniswap book at launch).

Each launch creates a fair-launch ERC-20 and a bonding curve. Traders push the curve forward by buying with the underlying (or ETH, when a liquid route exists). When the curve holds $6,000 of backing value, it graduates into a permanently locked Uniswap V4 pool — with the same fee rules enforced by a hook. Direct skips the curve and uses that same 1% stock-leg hook plus optional holder tax from block 0.

• Creators — launch a ticker-backed coin, earn creator fees on every trade (curve and post-grad), optionally enable holder tax.
• Traders — buy early on the curve, exit anytime (subject to liquidity), track live price and 24h change from on-chain + indexed history.
• Holders — if a launch enables holder tax, claim accrued underlying stock from the dashboard or token page.
• BACK holders — deposit BACK, earn NVDA.

1. You pick a listed stock — or Absorb, or a basket of 2–5 stocks — and launch. The factory deploys your coin + curve and charges a small ETH creation fee.
2. People buy on the bonding curve. Fees are paid in the underlying (stock or basket shares), not in your meme ticker.
3. Price and “progress to graduation” track how much stock value sits in the curve (oracle-priced).
4. At $6,000 backing, liquidity moves to Uniswap V4 and locks. Trading continues on the pool with that launch type’s hook skimming the same fee schedule (plus Absorb’s extra 1% on Absorb markets).

Single-stock launches go through the StockBack factory. Absorb launches use a dedicated factory — your wallet will show that address as the spender. Verify you’re interacting with the right one before signing. Full list: Contracts.
