Buy and burn
How $PLINK leaves circulation.
The burn share of every round's fee is set aside in SOL. Once it reaches 0.005 SOL, the keeper buys $PLINK on the open market through Jupiter and burns everything it bought in a second transaction.
Both transactions are public. The Explore page lists every burn with links to the buy and the burn on Solscan.
Until $PLINK is live, the burn share keeps building in SOL and is spent on the first burn after launch.
