[smypmsa]

Hey there. Pump.fun is shipping a breaking program upgrade on 2026-04-28, 16:00 UTC — new fee recipient account on the bonding curve, two new accounts on PumpSwap. Details from the pump team:

https://t.me/pump_tech_updates/40
https://github.com/pump-fun/pump-public-docs/blob/main/docs/BREAKING_FEE_RECIPIENT.md

The bot is already up to date:

• IDL refreshed
• Listeners + decoders updated
• Bonding curve buys/sells now ship the 18 / 16-17 account layout
• PumpSwap learning-examples send the +2 breaking-fee accounts after pool-v2
• src/ core mirrors all of the above

Pull main and you're good. If anything misbehaves on mainnet post-cutover, let us know.

"Good news, everyone!"
