Overview
Minswap Aggregator is a DEX aggregation tool integrated into the Minswap decentralized exchange on Cardano. It scans liquidity across all Cardano DEXs to find the best available swap rate for each trade, routing orders through optimal paths that may span multiple pools and protocols.
The aggregator operates as part of Minswap's V2 architecture, built using the Aiken smart contract language. It evaluates swap routes across constant-product pools, stableswap pools, and concentrated liquidity pools to determine whether a direct trade or a multi-hop path through intermediate tokens yields the best price. Users see the recommended route and alternatives before confirming a transaction.
Minswap Aggregator connects to a broader DeFi platform that includes liquidity provision, yield farming, MIN token staking, and community governance through a dedicated governance forum. The protocol operates without private or venture capital investment, distributing MIN tokens to protocol participants and liquidity providers1.
Key Features
- Smart order routing. A routing algorithm compares prices across multiple pools and protocols, automatically selecting the cheapest execution path including multi-hop routes through intermediate tokens2.
- Advanced order types. Supports limit orders with partial fill options, stop-loss orders, OCO (one-cancels-the-other) brackets, and zap-in/zap-out for single-asset liquidity provision3.
- Dual audit security. The V2 smart contracts underwent independent audits by CertiK and Anastasia Labs, funded through a Cardano Catalyst proposal, followed by a public bug bounty program23.
- Public aggregator API. Developers can access swap estimation, transaction building, order management, and multi-protocol routing through a documented REST API at
agg-api.minswap.org4. - Dynamic fee structures. Pool trading fees range from 0.05% to 20%, with support for volatility-based dynamic fees and separate buy/sell fee configurations set through governance votes3.
What to Expect
The Minswap Aggregator interface presents a swap form where users select input and output tokens, enter an amount, and receive an estimated output with the optimal route displayed. The routing breakdown shows which pools and protocols each leg of the trade passes through, along with fee totals and price impact.
Connecting a Cardano wallet such as Eternl, Lace, or Nami is required to execute trades. After confirming slippage tolerance and reviewing the route, the aggregator builds and submits the transaction. Pending orders can be tracked and cancelled directly through the interface. The fill-or-kill feature automatically refunds orders that fall outside the specified slippage range, reducing the need for manual cancellation.
Developers building on Cardano can integrate Minswap Aggregator functionality through the public REST API, which handles swap estimation, unsigned transaction construction, and order submission without requiring direct smart contract interaction4. The V2 architecture uses Plutus V2 reference inputs to reduce transaction size, and the order contract is independent of pool contracts, allowing protocol upgrades without liquidity migration3.
