Brook is a Uniswap v4 hook that turns swap fees into steady, paycheck-style LP yield. This page walks you through providing liquidity and claiming real yield on Unichain Sepolia — entirely from your own wallet.
Most LP income is volatile: big fees one week, nothing the next. Brook smooths it. A slice of every swap fee goes into an epoch buffer instead of paying out instantly. When the epoch ends, that buffer becomes the next epoch's payout pool, streamed to LPs and weighted by how long each stayed in range. Predictable income that committed liquidity can plan around.
Click Connect Wallet. The app switches you to Unichain Sepolia automatically.
Click Mint tokens to get demo tokens (DTA and DTB) sent to your wallet. These are free, open-mint test tokens.
Click Approve so the router can move your tokens when you provide liquidity and swap. Two quick approvals, one per token.
Click Add liquidity. You provide full-range liquidity, and your position is keyed to your address — so only you can claim its yield.
Click Swap. Twenty percent of the swap output skims into the epoch buffer. Watch the buffer figure climb on the main page.
Once the epoch timer reaches 100%, click Swap to roll — this moves the buffer into the payout pool. Then Claim yield sends your vested share to your wallet.
