BEX pools contain the logic and math for swapping tokens and for liquidity operations. There are several types of pools, each with its own unique characteristics and use cases.

​
Pool types

Weighted pools

Custom weights per token; best for uncorrelated assets.

Stable pools

Pegged or correlated tokens (e.g., stablecoins) with a known exchange rate.

​
Pool differences

​
Pool math

  • Weighted pools use constant product formulas (similar to Uniswap V2) and allow for custom weight distributions between tokens
  • Stable pools use specialized stable swap curves optimized for tokens that should trade near parity

​
Key parameters

  • Weighted pools are configured primarily through token weights (e.g., 80/20, 50/25/25)
  • Stable pools use an amplification coefficient to determine how tightly the prices should be bound together

​
Use cases

  • Weighted pools: Best for uncorrelated assets where price divergence is expected (e.g., HONEY/WETH)
  • Stable pools: Ideal for correlated assets like:
    • Stablecoins (USDC/USDT/DAI)
    • Wrapped/underlying tokens (iBERA/BERA)
