How Bullrun
works.

Bullrun is designed as a continuous onchain last-buyer game created in partnership with $BULL. When live, players trade RUN/ETH in one permanent Uniswap v4 pool on Robinhood Chain. The last identified qualifying buyer when a 45-minute round expires wins that round's BULL + RUN pot. Leader time also carries into a separate weekly Top 8 race.

The gross ETH leg actually executed by an ETH to RUN buy must be at least the current floor. The floor starts at 0.01 ETH and multiplies by 1.003 after every qualifying buy. A smaller buy can still trade, but it cannot reset the clock, raise the floor, or take the lead.

Every pre-expiry qualifying buy resets the active round to 45 minutes. Sells never reset it. Round one begins at launch, and each successful settlement opens the next round with a fresh 45-minute clock.

The last identified qualifying buyer standing when the clock expires. That leader locks at expiry, anyone can finalize the round, and the next round opens atomically. Winner selection is deterministic. There is no random draw.

The winner receives the round's realized BULL and RUN. ETH reserved for player rewards is shown separately as pending BULL conversion until the protocol swaps it. Pending ETH is not an extra ETH prize and is never multiplied by an ETH price to describe BULL rewards.

The pool charges a static 1.50% LP fee. On buys, the 1.00% player share and 0.10% burn share route from ETH into BULL. On sells, the 1.00% player share stays in RUN, while the 0.10% burn share routes RUN to ETH to BULL. The remaining 0.40% stays as platform revenue in the asset collected. Integer rounding is handled onchain.

The 1.00% player share is split into a nominal 0.80% active-round lane and 0.20% weekly Top 8 lane. Buy-side player ETH converts into BULL for those lanes. Sell-side player RUN remains RUN. That is why reward surfaces show BULL + RUN, plus any ETH still pending BULL conversion.

A nominal 0.10% burn lane buys BULL and sends it through the protocol burn path. Buy-side ETH can route directly into BULL. Sell-side RUN first routes through ETH and then into BULL. Burn accounting is separate from round and weekly player pots.

The protocol records how many seconds each wallet is the identified leader during the UTC week. Time carries across round boundaries and stops when that wallet loses the lead or the round expires. The final eight wallets share the week's BULL + RUN pool pro rata by their Top 8 seconds. Equal times keep the wallet that first became a leader that week ahead.

Every regular week runs from Monday 00:00 UTC to the next Monday 00:00 UTC. If Bullrun launches partway through a week, the first period begins at launch and still closes at the next Monday boundary. Its pool is not prorated.

If an entire closed week has no positive recorded leader seconds, its BULL + RUN pool and any pending BULL conversion move to the active round pot during settlement. It is not assigned to a future weekly leader.

No. The floor measures the gross ETH leg executed by the qualifying buy, not a RUN holding, escrow, or bond. Selling later does not surrender leadership or undo a clock reset. A round trip still carries gas, fee, residual price-impact, and execution risk.

Claims are separated by asset. The Hook can harvest fees, settle ended weeks, finalize an eligible expired round, and pay realized round RUN. The leaderboard pays finalized weekly RUN. The verified fee vault pays all realized BULL owed to the wallet, including round and weekly allocations. Displayed estimates and pending ETH conversion are not claimable as if they were realized BULL.

Two exact approvals: RUN to Permit2, then a short-lived Permit2 allowance to the Universal Router for that amount. The Bullrun interface never asks for an unlimited approval.

Token prices can move sharply. Quotes can fail, transactions can revert, the floor compounds with activity, and defending a lead costs fees, price impact, and gas. Pending conversions can settle at a different execution rate. Robinhood Chain ordering, timestamps, availability, and transaction inclusion can affect the result. Every trade, lead, rank, and claim is public onchain. Read every wallet request before signing.
