Overview
What Get Berrier is
A plain-language tour of the product, its two legs and the modules behind them.
The product in plain terms
A note is a fixed agreement about one stock over thirteen weeks. If the stock keeps closing at or above a barrier, the cash side earns a coupon every week. If it rallies to the autocall level, the note ends early and everyone goes home with what they put in plus what they earned. Only a final close below the barrier changes the outcome: the cash side then receives the stock at its starting price.
The two legs
| CARRY | GUARD | |
|---|---|---|
| Deposits | USDG | Stock Tokens plus a USDG prefund |
| Receives | Weekly coupons | Its stock back, unless the barrier breaks at maturity |
| Gives up | Upside above the coupon; takes stock at S0 on a breach | The coupons it funds |
| Holds | A short put struck at S0, paid for by the coupon | A long put struck at S0 |
Both legs are ERC-1155 tokens minted by BarrierLegs, so either can be held, transferred, used as collateral in Credit or moved to another chain with Omni.
What the protocol does not do
- It does not lend. No position carries debt, so nothing is ever liquidated.
- It does not quote prices. Coupons clear from the deposits on each side.
- It does not hold custody off-chain. Every token sits in escrow contracts on Robinhood Chain.
- It does not observe intraday. Only the scheduled official close counts.
