Vault Takes
Deposit a bag + ETH, take at random.
Open Vault Takes. Depositors lock a Greenback launch token with ETH backing within ±50% of bag fair value. Pricing uses the bonding curve before graduation and the Uniswap V4 meme↔stock pool after — bags listed pre-grad auto-switch if the token graduates mid-life. Takers pay the pool’s average backing plus a surcharge; a position is drawn with inverse-weight odds from a frozen snapshot (lighter bags are more likely). Then keep the tokens or take the cash bid.

No instant exit
Withdraw is two-step: request → delay (still take-eligible) → finalize. Takes form a FIFO queue so the desk stays under continuous demand.
Pricing hygiene
Graduated deposits require minimum V4 pool liquidity and a fresh stock oracle. Thin or stale books cannot pass the backing band.
Randomness
v1 uses delayed blockhash entropy on Robinhood Chain (no Chainlink VRF on 4663 yet). L2 sequencers can bias blockhashes — treat as interim.
Rules
The desk has one job: match ETH bids to Greenback bags under clear constraints. Everything else follows from that.
- Band first. Every deposit locks launch tokens with ETH inside ±50% of on-chain bag fair value (curve spot before graduation, Uniswap V4 after). Outside the band, the deposit reverts.
- Pay the pool. Takes cost average active backing plus the surcharge. Protocol cut and fee drip settle at request; remaining bags earn equal per-seat drip while they sit.
- Lighter is likelier. When a take activates, the vault freezes the eligible set and ETH weights. Inverse-weight draw favors light bids; later rebalances cannot rewrite those odds.
- Settle once. On reveal, the taker keeps the tokens (lister gets most ETH back) or takes the cash bid (~88% of that bag’s ETH; tokens return). Timeout defaults to cash bid.
- Exit slow. Withdraw is request → delay (still takeable) → finalize. Graduation does not move your tokens — only the pricing path switches curve → V4 for the band.
