Automatic fee-funded buyback
Every trade fee routes into an on-chain buyback of $HPERP. No treasury discretion, no manual trigger: code, not a promise.
- Fees accumulate as USDG in the BuybackVault
- Keeper swaps USDG → WETH → $HPERP on Uniswap v3
- Purchased tokens burn to 0x…dEaD. Supply only shrinks.
