Constant pools operate similarly to Uniswap V2, using the constant product formula: 𝑥 × 𝑦 = 𝑘. Where: • 𝑥 and 𝑦 are the reserves of two assets in the pool, • 𝑘 is a constant that remains unchanged during trades, ensuring that price adjustments happen algorithmically. **What assets does STEAMM support?** At launch, STEAMM Beta supports the following asset pairs and fee tiers: * SUI-USDC (0.3%) * SEND-SUI (2%) * wBTC-USDC (0.3%) * wBTC-SUI (0.3%) **What fees does STEAMM have?** When swaps are made via STEAMM, a protocol fee of 20% is incurred. For example, if a swap is made from a pool with a fee tier of 0.3%, 80% of the fee (0.24%) is distributed to liquidity providers (LPs), while the remaining 20% (0.06%) is reserved as the protocol fee.
