How it works
Three moves.
One of them pays you.
-
01
Buy
Swap into Stock Tokens through the Backspin router on Uniswap v4. A per-trade price-impact guard stops a large order before thin liquidity gives you a bad fill.
-
02
Hold
Your holdings are valued every hour. Your 30-day average decides your cashback tier, so steady holders aren't outranked by a one-day spike.
-
03
Claim
Cashback builds up each epoch and vests over time. When the epoch closes, your share lands in a claim root — one transaction and it's yours.
Cashback
Hold more, longer.
Get more back.
Your tier comes from your average holding over the last 30 days. Cashback is capped per trade and scaled to the remaining budget, so the program can't promise more than it holds.
Tier levels shown are illustrative. Final thresholds are set at launch.

The engine
One buy starts
a chain of work.
Every number is counted the same way, every time. Nothing is typed in by hand.
1
Indexer
Records every router buy and sell. Keyed by transaction hash and log index, so one transaction can hold several trades.
2
Valuer
Writes an hourly snapshot of what each wallet holds.
3
Tier engine
Measures the 30-day average and assigns the tier.
4
Accrual
Applies the high-water mark, per-trade cap, budget scale and vesting.
5
Epoch builder
Prepares the claim root at the end of each epoch.
Contracts
No upgrade button.
On purpose.
The code at each address stays fixed. A change means a new deployment you can see — never a silent swap.
BackspinRewards
Holds epoch claim roots and pays out cashback that has finished vesting.

CashbackBudget
Caps what the program can pay. When the budget runs low, rewards scale down — they don't overdraw.

Precision
Counted in micro-units.
Shown in dollars.
Trades, grants, claims, budgets and holdings are stored as whole numbers of USDG micro-units. The ledger keeps the exact amount; the app is just where it becomes a familiar dollar figure.
