What's inside Astroport

  1. Overview of ASTRO and ASTROC tokens

    ASTRO (on Terra 2) and ASTROC (on Terra Classic) are the native tokens of the Astroport ecosystem. They serve as the primary tools for coordinating and aligning incentives among stakeholders, allowing users and builders to own, control, operate, maintain, and update the Astroport smart contract system on their respective blockchains.

  2. Overview of the Astroport Maker contract

    The Maker contract is responsible for collecting a portion of Astroport's pair fees (defined by the factory's maker_fee). These accrued fees are swapped into ASTRO and distributed to stakers and governance based on the governance_percent configuration.

  3. Overview of Emissions Voting with vxASTRO

    The vxASTRO contract allows xASTRO token holders to lock their tokens to participate in Emissions Voting, which directs ASTRO emissions. vxASTRO holders can allocate their voting power to a maximum of five pools once per epoch. Once votes are cast, they cannot be changed until the next epoch.

    Key characteristics of vxASTRO include:

    • Non-Transferable: Tokens cannot be swapped or transferred between addresses.
    • Governance: Holders retain their standard Astroport Governance voting power while tokens are locked.
    • Emissions Interaction: The contract interacts with the Emissions Controller to update a user's contribution to Emissions Voting whenever their balance changes.

  5. Overview of Astroport's role in the Cosmos ecosystem

    Astroport is designed as a next-generation Automated Market Maker (AMM) serving as the underlying liquidity layer for the Cosmos ecosystem. Its primary objective is to provide deep liquidity pools and high trading volumes to support various DeFi primitives, including:

    • Liquidity mining programs for new Cosmos tokens (including dual rewards).
    • Price oracles and data for credit protocols (e.g., Mars Protocol).
    • Infrastructure for index products and token baskets.
    • Liquidity sourcing for wallets and trading aggregators.
    • The base liquidity layer for yield farming protocols.

  6. Overview of the Astroport Router contract

    The Router contract facilitates multi-hop swaps for Cosmos native and CW20 tokens. It allows users to route trades through multiple pools to optimize for the best output.

  8. Overview of the Astroport Factory contract

    The Factory contract creates and manages Astroport pair contracts and associated LP token contracts. It maintains a registry that serves as a directory for all pairs. Supported pair types include constant product (XYK) and stableswap, with the possibility for governance to add custom pool implementations.

  11. Overview of the Native Coin Wrapper

    The Native Coin Wrapper converts native coins into equivalent CosmWasm (CW20) tokens. This allows native coins to be used for deploying proxy rewards and connecting with reward generators within the Astroport ecosystem. Native coins are held in escrow by the contract while the equivalent CW20 tokens are minted. Users can later burn these CW20 tokens to release the original native coins from escrow.

  12. Overview of the Astral Assembly contract

    The Astral Assembly contract enables xASTRO holders and Initial Astroport Builders to create and vote on on-chain proposals that can execute arbitrary logic.
