Devs deploy a permanent pool, buyback or refund at a rate they fix at deploy. Holders redeem against the pool's SUI reserve in one signed transaction. Once it's live, the terms are locked on-chain. No admin override.
Pick a coin, set a rate (mist per token), choose the recipient (burn or buyback), seed the reserve with SUI. One transaction, one shared pool object.
Anyone can deposit more SUI into the reserve — typically the dev as redemptions happen. The pool's terms never change; only the depth changes.
Holders burn (or transfer) their coins via the pool, receive SUI at the fixed rate minus the platform fee, all in a single signed transaction.
