Astroport Review 2026: Passive Liquidity on Cosmos

Astroport is a decentralized exchange and automated market maker built for the Cosmos ecosystem. DefiLlama calls it the meta AMM of Cosmos, and the homepage describes a permissionless liquidity network where users swap tokens and provide liquidity.

DefiLlama lists it on Terra (terra2), Injective, Osmosis, Neutron and Sei, with about $2.7 million in TVL. It has been tracked since June 2023 and has the ASTRO token. The listing shows two audits.

The pitch is passive liquidity: pools designed so providers do not need to rebalance positions often. Other Cosmos projects build on top, including lending and auto-compounding services.

This review draws on public data and the project's own homepage, not hands-on use.

Astroport is an automated market maker. Instead of an order book, traders swap against pools of two or more tokens that liquidity providers have deposited. The pool's pricing formula sets the exchange rate, and providers earn a share of the trading fees.

According to the homepage, Astroport uses algorithmic pools that it says are up to three times more efficient than traditional pools. The aim is to give traders better prices and providers better returns without active position management, which it calls passive liquidity.

Pools and incentives are permissionless, so anyone can create a pool or direct incentives to attract liquidity. Liquidity positions are fungible tokens, so other protocols can use them. The homepage names Mars, which lets users borrow against liquidity positions, and Apollo, which offers auto-compounding vaults. It also names Eclipse Equinox for meta-governance and NCoS for community vxASTRO voting.

Astroport's fees are not published. Trading fees on an AMM like this are usually set per pool and charged on each swap, with most of the fee going to liquidity providers. Users should see the fee, the expected price impact and the network gas cost in the app before approving a swap, and should check the documentation for the pool types in use.

Providing liquidity also carries costs that are not fees, mainly impermanent loss and chain gas costs. The homepage says its pool design minimises impermanent loss, but public sources give no figures.

DefiLlama lists two audits, but the project does not name the auditors or the findings. Like any DEX, Astroport is non-custodial: you keep your tokens in your own wallet and interact with smart contracts. The main risks are smart-contract bugs, risky or illiquid pools, and the chains and bridges involved.

Permissionless pool creation means some pools may hold low-quality tokens. Check the token pair, liquidity depth and incentives before depositing. No incidents are mentioned publicly, and none should be assumed either way. The homepage links terms of use and a privacy policy, which are worth reading. Check that using DeFi services is permitted where you live.

Astroport is for users of Cosmos-ecosystem chains such as Terra, Neutron, Injective, Osmosis and Sei who want to trade or earn from liquidity provision. It also suits protocols and treasuries wanting permissionless pools for their tokens. Newcomers should be comfortable with wallets, gas fees and impermanent loss before depositing.
