Pump.fun's BOOST Mode Turns Dead Liquidity Into Automatic Buybacks
Every pump.fun coin that migrates after 10:23 EST July 21 now recycles the ~$100M lost yearly to dead liquidity into five minutes of buybacks and burns.
Pump.fun changed how every new coin goes public. As of 10:23 EST on July 21, the Solana launchpad turns on what it calls BOOST mode for every token that migrates off its bonding curve, spending the liquidity that normally dies at migration on five minutes of automatic buybacks and burns. There is no switch to flip and no way to opt out. It is now the default for every bonded coin.
The framing is unusually blunt for a launchpad. Pump.fun is telling traders it had been quietly losing their capital at the exact moment a coin was supposed to grow up, and that it built a mechanism to claw that money back.
The dead liquidity problem
When a pump.fun token graduates, its pooled liquidity moves to a live market. Historically about 20% of that liquidity got stranded on the way: capital locked in the LP that no trader can ever pull out, even after everyone has sold. Pump.fun calls it dead liquidity. By its own accounting, more than $100 million of it disappears this way every year, money the platform argues could have gone back into the very coins traders worked to migrate.
How the buybacks work
BOOST redirects that stranded capital instead of letting it sit. For five minutes after a migration, the platform uses the freed liquidity to buy the token on the open market: 17.6 SOL for coins paired against SOL, or $2,516 for USDC pairs. Each purchase runs through a TWAP, spreading the buys across the window, and every token it picks up is burned on the spot. Pump.fun says the trading experience is unchanged for users. The difference sits under the hood: a coin's first minutes now carry a built-in bid and a supply that ticks down, instead of a pool quietly bleeding value.
Who gets it
The configuration is automatic and near-universal, with two carve-outs. Coins that migrated before the 10:23 EST cutoff keep their old setup, and anything launched via Mayhem is excluded. Everything else that bonds from here forward ships with BOOST built in. Whether five minutes of forced, burning demand actually changes how a coin trades right after it graduates is the thing the next batch of launches will settle.
