Jup Swap with Compressed Tokens - Demo

• Creates a single swap transaction with additional instructions: createInAtaIx, decompressIx, closeInAtaIx
• Accepts compressed tokens as tokenIn.
• Cleans up ATA for tokenIn after swap.
• Does not clean up nor compress tokenOut. (Enable this via CPI)

Notes

• Demo requires directSwapsOnly=true to avoid occasional tx size overrun (+ ~300 bytes overhead). This can be fixed by integrating natively in Jup's API for setupInstructions and cleanupInstructions.

• Further optimization paths:

  • Add compressTokenOut option. Requires invocation via CPI to get exactOut.
  • Enable use of sharedTokenAccounts to avoid opening and closing ATAs for tokenIn/tokenOut.

Setup

1. Create .env from .env.example
2. Fund FILE_WALLET at SWAP_USER_KEYPAIR_PATH with small amount of INPUT_MINT.
3. May require large slippage/priority fee to land. you can change configs in src/constants.ts.

Run

yarn

# get quotes, see tx size
ROUNDS=5 yarn dryrun    # runs 5 rounds
yarn dryrun            # runs 1 round (default)

# also send and confirm
ROUNDS=5 yarn send      # runs 5 rounds
yarn send              # runs 1 round (default)

No safeguards. Use at your own risk. Set small amounts. ensure your INPUT_MINT tokenBalances are small.
