Overview
Minswap Aggregator is a price-finder for Cardano token swaps that is built straight into the Minswap trading app. It checks every Cardano exchange at the same time and picks the route that gives you the most tokens back, sometimes splitting a trade across several pools to do even better.
Under the hood, it looks at three kinds of pool (the technical names are stableswap, constant-product, and concentrated liquidity, all just different ways exchanges run their pricing) and works out whether a direct swap or a two-step path through a middle token will get you a better deal. You see the chosen route on the screen before you confirm.
Minswap Aggregator is part of a larger Cardano DeFi platform that also lets you supply tokens to liquidity pools, earn yield, stake the MIN token, and vote on changes through a community governance forum. The project runs without venture-capital backing; MIN tokens are distributed to the people who use and support the protocol.1
Key Features
- Best-price search across exchanges. A routing engine compares prices across every Cardano pool it can see and picks the cheapest path, including two-step swaps through a middle token when that helps.2
- Advanced order types for active traders. Set a target price with a limit order (and let it fill in pieces), pair a take-profit with a stop-loss so one cancels the other, or add and remove liquidity with a single click. New traders can ignore these; they are there for the people who want them.3
- Two independent security audits. Minswap's smart contracts were reviewed by CertiK and Anastasia Labs, paid for through a community Catalyst grant, followed by a public bug bounty before launch.23
- Public API for developers. Other apps and bots can use Minswap Aggregator's routing through a documented connection at agg-api.minswap.org, with endpoints for getting a quote, building a transaction, and managing orders.4
- Adjustable trading fees. Pool fees range from 0.05% to 20% depending on the pool, and the community can vote to change them. Some pools can also adjust their fees automatically when the market is volatile.3
What to Expect
The swap screen is the centerpiece. You pick a token to sell, a token to buy, and enter an amount. Minswap Aggregator shows the estimated tokens you will receive, which pools and exchanges your trade will pass through, and how much of the price is fees vs. slippage (slippage is when a trade fills at a worse price than the screen quoted, usually because the trade is large enough to move the market).
You will need to connect a Cardano wallet such as Eternl, Lace, or Nami to actually trade. After you confirm slippage tolerance and review the route, the app builds the transaction and sends it. Open orders sit on a separate screen where you can cancel them. A fill-or-kill option lets you say: if the trade cannot finish at the price I want, give me my tokens back instead of half-filling.
For developers, the public API gives the same routing power Minswap uses on its own site. The smart contracts use a modern Cardano feature (reference inputs) to keep transactions smaller, and the part of the system that handles your order is kept separate from the part that holds pool funds, so upgrades can happen without anyone having to move their liquidity.3
