StableSwap-NG: Overview

Contract Source & Deployment

Source code is available on GitHub. The following documentation covers source code up until commit number 5f582a6.

All stableswap-ng deployments can be found in the "Deployment Addresses" section.

For an in-depth understanding of the StableSwap invariant design, please refer to the official StableSwap whitepaper.

The Stableswap-NG AMM infrastructure represents a technically enhanced iteration of the previous stableswap implementation. It comprises the following key components:

  • AMM Blueprint Contracts

    Stableswap-NG has two main implementations:

    • Plain Pools
    • Metapools

    The admin controls for pools are documented separately.

  • Pool and Gauge Factory

    The Pool Factory is used to permissionlessly deploy new plain and metapools, as well as liquidity gauges. It also acts as a registry for finding the deployed pools and querying information about them.

  • Math Contract

    Contract which provides mathematical utilities for the AMM blueprint contracts.

    CurveStableSwapNGMath.vy

  • Views Contract

    Contract targeted at integrators. Contains view-only external methods for the AMMs.

    CurveStableSwapNGViews.vy

  • Liquidity Gauge Blueprint Contract

    A liquidity gauge blueprint implementation which deploys a liquidity gauge of a pool on Ethereum. Gauges on sidechains must be deployed via the RootChainGaugeFactory.

  • Oracles

    Exponential moving-average oracles for the D invariant and for the prices of coins within the AMM.
