LetsBonk (Bonk.fun)
Bonk.fun (formerly LetsBonk.fun) is a Solana memecoin launchpad from the BONK community, built on Raydium's LaunchLab infrastructure and launched in April 2025. Nasdaq-listed Bonk, Inc. holds a 51% revenue interest in the platform.
Cost: BONK Classic launches (introduced 2026-01-14) charge a 0.30% swap fee with no creator fee. BONKERS launches cut swap fees by up to 50% but let creators add higher creator fees. Bonk.fun does not publish its own platform cut; its terms say fees are shown before confirmation. The 0.30% is the launch's total swap fee, not a published Bonk.fun app fee, so no platform-only round-trip cost is stated. Trading both ways on a BONK Classic launch costs about 0.6% in swap fees.
