DeFi operations on Stacks — ALEX DEX token swaps and liquidity pool queries, plus Zest Protocol lending (supply, withdraw, borrow, repay, claim rewards). All operations are mainnet-only. Write operations require an unlocked wallet.

DeFi Skill

Provides DeFi operations across two protocols:

  • ALEX DEX — Automated Market Maker (AMM) on Stacks for token swaps. Uses the alex-sdk for routing and price discovery. Mainnet-only.
  • Zest Protocol — Lending and borrowing protocol on Stacks. Supply assets to earn interest, borrow against collateral. Mainnet-only.

Write operations (swap, supply, withdraw, borrow, repay, claim-rewards) require an unlocked wallet (use 

bun run wallet/wallet.ts unlock
first). Read operations (get-swap-quote, get-pool-info, list-pools, list-assets, get-position) also require an unlocked wallet for routing context.

Usage

bun run defi/defi.ts <subcommand> [options]

Notes

  • ALEX DEX and Zest Protocol are mainnet-only. Calls on testnet will return an error.
  • For ALEX swap quotes, you can use token symbols (
    STX
    , 
    ALEX
    ) or full contract IDs. Use 
    alex-list-pools
    to discover available pairs.
  • For Zest operations, you can use asset symbols (
    stSTX
    , 
    aeUSDC
    , 
    sBTC
    ) or full contract IDs. Use 
    zest-list-assets
    to discover supported assets.
  • Wallet operations require an unlocked wallet (use 
    bun run wallet/wallet.ts unlock
    first).
  • Borrow operations require sufficient collateral in the protocol. Ensure you have supplied assets before borrowing.
