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.
