Changes

  • Add multiple curve possibilities on top of the traditional constant product / Uniswap curve
    • constant price: price fixed at pool creation
    • constant product with offset: adds a faked amount of liquidity on one side of the pool, useful for new coin offerings
  • Add ability to deposit and withdraw a single token type, instead of both at once
  • Improve calculations

Build

The token swap program contains hard-coded constraints on fees and fee account owners. For this build, available at program id SwaPpA9LAaLfeLi3a68M4DjnLqgtticKg6CnyNwgAC8 on devnet, testnet, and mainnet-beta, the fee account for any pool must be owned by HfoTxFR1Tm6kGmWgYWD6J7YHVy1UwqSULUGVLXkJqaKN.

Run the build command from token-swap/program:

SWAP_PROGRAM_OWNER_FEE_ADDRESS=HfoTxFR1Tm6kGmWgYWD6J7YHVy1UwqSULUGVLXkJqaKN cargo build-bpf --features=production
