Examples to zap_in damm v2

  1. User has 1 SOL, and want to add liquidity in pool SOL-USDC, then they will send a batch of transactions (can use jito):
  • Swap 0.5 SOL to USDC in JUP or directly through AMMs
  • Call endpoint initialize_ledger_account to create a ledger account
  • Set balance for token a (SOL) to 0.5 SOL in ledger account through endpoint set_ledger_balance
  • Set balance for token b (USDC) through endpoint update_ledger_balance_after_swap, it will take output USDC from step 1
  • Call zap_in_damm_v2 to add liquidity in damm v2
  • Close ledger account through endpoint close_ledger_account
  1. User has 1 SOL, and want to add liquidity in pool MET-USDC, then they will send a batch of transactions (can use jito):
  • Swap 0.5 SOL to MET in JUP or directly through AMMs
  • Swap 0.5 SOL to USDC in JUP or directly through AMMs
  • Call endpoint initialize_ledger_account to create a ledger account
  • Set balance for token a (MET) through endpoint update_ledger_balance_after_swap, it will take output MET from step 1
  • Set balance for token b (USDC) through endpoint update_ledger_balance_after_swap, it will take output USDC from step 2
  • Call zap_in_damm_v2 to add liquidity in damm v2
  • Close ledger account through endpoint close_ledger_account

Examples to zap_in DLMM

  1. User has 1 SOL, and want to add liquidity in pool SOL-USDC, then they will send a batch of transactions (can use jito):
  • Swap 0.5 SOL to USDC in JUP or directly through AMMs
  • Call endpoint initialize_ledger_account to create a ledger account
  • Set balance for token x (SOL) to 0.5 SOL in ledger account through endpoint set_ledger_balance
  • Set balance for token y (USDC) through endpoint update_ledger_balance_after_swap, it will take output USDC from step 1
  • Call zap_in_dlmm_for_uninitialized_position, that will create position and add liquidity to that position
  • Close ledger account through endpoint close_ledger_account
  1. User has a position (SOL-USDC) that is out of range and they want to rebalance the position to concenstrate around pool price, they they will send a batch of transactions:
  • Withdraw 100% position,
  • Call endpoint zap_out to swap half of SOL to USDC
  • Call endpoint initialize_ledger_account to create a ledger account
  • Set balance for token x (SOL) through endpoint update_ledger_balance_after_swap, delta of SOL changed in user token balance
  • Set balance for token y (USDC) through endpoint update_ledger_balance_after_swap, delta of USDC changed in user token balance
  • Call zap_in_dlmm_for_initialized_position, that will rebalance position with the new balances
  • Close ledger account through endpoint close_ledger_account
