Ratchet
Every trade buys it back. Then locks it.
Half of the creator's fee share on $RATCHET buys the coin back off the market and locks it in a five-year vest. The pons contract runs it on every sweep.
Enforced, not promised
The launch sets the pons buyback flag. On each fee sweep the contract spends the earmarked slice buying $RATCHET and hands the tokens to the buyback vault. You can read every BuybackLocked event on Blockscout.
What the slice is
Every trade pays a 1% base fee plus a 3% creator tax. Half of the creator's share of the base fee, 0.35% of each trade, is the buyback. The tax is separate and stays with the creator.
Five-year vest, not a burn
Bought tokens are locked in PonsV2BuybackVault and vest linearly over five years, released to the creator and the protocol on the launch's fee split. Nothing is burned; supply leaves the market now and trickles back over five years. If the curve is too thin to absorb a buyback, that sweep pays the creator instead and the next one tries again.
