House rules
Short on purpose. The split, the minimums, and what happens when a swap fails. The machine's pinned addresses live in the rail.
Every bid credits its full amount to the coin's rank. A 10% platform fee comes off the top, and the remaining 90% splits evenly: half market-buys the coin and burns the tokens, half market-buys MEMEBID and burns it.
Minimum bid is 0.1 SOL. Outbidding a coin requires exceeding its total by at least 0.05 SOL.
All bids are final. No refunds under any circumstances.
If a coin cannot be bought after three attempts, that half of the bid buys and burns MEMEBID instead. No funds are ever stuck.
Tokens, on chain, forever. After the 10% platform fee, half of what remains buys the coin you bid on and sends every purchased token to the incinerator, a Solana address nobody can spend from. The other half does the same with MEMEBID. Both burn transactions carry public signatures, linked on the transparency page.
To the engine wallet, which buys and burns within seconds of confirmation. The engine's pubkey is pinned in the rail; every transfer to it is public.
A bid intent stays open for 30 minutes. If no transfer lands inside that window the intent expires and nothing is owed. Paying after expiry does not credit a rank; that SOL is held for manual review and refunded by hand.
Only the exact amount (or more) credits a bid. An underpayment or a transfer from a different wallet than the one that opened the intent does not credit; it lands in the review queue and is refunded by hand. Overpayments credit in full.
Rarely, a Solana transaction that reads as confirmed later rolls back in a fork. The engine re-checks finalization before spending anything, so no SOL is ever spent behind a rolled-back bid. The bid is marked reverted and the rank credit is removed.
Confirmed bids, yes: the SOL is already bought and burned, and a burn cannot be undone. The exception is money that never became a bid, like the wrong-amount and late transfers above. That SOL never burned anything, so it goes back.
The engine retries three times with rising slippage. If the coin still cannot be bought, that half of the bid buys and burns MEMEBID instead, and the job is marked redirected on the transparency page. Funds never sit idle in the engine wallet past the retry window.
Every confirmed bid on the transparency page links its four signatures on Solscan: your transfer, the coin-side swap, the coin-side burn, and the MEMEBID-side pair. The incinerator address is public and its holdings can be checked directly.
