AMM Pool Mapping

Below table maps the pool listed on https://app.alexlab.co/pool to smart contracts with the relevant parameters

Pool Types

We have three smart contracts in production that provide AMM.

Trading Pool

Trading Pool is the latest AMM smart contract that developers should use whenever possible.

Trading Pool implements Generalised Mean Equation and, with a suitable parameterisation, supports both risky pairs (i.e. x y=L), stable pairs (i.e. x +y=L) and any linear combination in-between (i.e. Curve).

Trading Pool is parameterised with a single parameter t. t can be between 0 and 1, with t=1 being equivalent of constant product formula (i.e. Uniswap V2) and t=0 being equivalent of constant sum formula (i.e. mStable). 0<t <1 then gives a Curve-like formula.

Fixed Weight Pool

Fixed Weight Pool is based on Balancer and allows to create AMM pools with custom (i.e. non equal-weight), fixed-weight, pools.

Fixed Weight Pool has been deprecated since the introduction of Trading Pool.
