# Program Upgrade

Hi. We will be doing a breaking program upgrade on April 28th, 16:00 UTC, to both the pump bonding curve program and the pump swap amm program. In order to make sure your integrations do not break please see the instructions below:

## These are 8 new fee recipients ( common for both programs )

## As part of this change,

- Bonding curve: A new account is required to be added in buys and sells
- AMM: 2 new accounts required to be added in buys and sells

All accounts till bonding-curve-v2 and pool-v2 remain the same, no change needed

## Bonding Curve

- Add any one of the 8 new fee recipients at the end of the buy and sell instructions.
- This new account should be added AFTER the bonding-curve-v2 account for both buys and sells.
- Account needs to be mutable
- Buy instructions should have 18 accounts in total
- Sell instruction should have 16 accounts for non cashback coins
- Sell instruction should have 17 accounts for cashback coins

## Pump swap ( AMM )

- Add 2 new accounts in this order at the end:
  - One of the 8 fee recipients. ( Second last account, readonly)
  - Quote mint ATA for fee recipient. ( Last account, mutable )

- These 2 new accounts should be added AFTER the pool-v2 account for both buys and sells for coins that graduate from bonding curve.
- Even if the coin is not a bonding curve coin, the 2 new accounts are necessary to be added.
- Buy instructions should have 26 accounts for non cashback coins.
- Buy instructions should have 27 accounts non cashback coins
- Sell instructions should have 24 accounts for non cashback coins.
- Sell instructions should have 26 accounts for cashback coins.
