Pump Developer Updates

Hi! We started extending the bonding curve PDA accounts from 49 bytes to 256 bytes to support future protocol updates. We recommend not depending on the size of the bonding curve accounts for backend logic, but on the Anchor account discriminator. We also suggest prepending extendAccount(bondingCurve) instructions before any Pump buy / sell tx if the bonding curve size is less than 256 bytes. In the future, buy / sell txs on not extended bonding curves will fail unless the bonding curve is extended first to 256 bytes.

The pump bonding curve contract has just been upgraded at: March 18, 2025 17:17:14 UTC. It is also a routine upgrade with no breaking changes.
