Supported DEX's
5. Swap across Cardano DEXes to choose a DEX or use the aggregator.
Surge trades on four Cardano DEXes: Minswap, SundaeSwap, WingRiders and Splash. They behave differently in ways that matter to you. Only Minswap automatically refunds an order that cannot fill.

Batcher fees and deposits are the values Surge uses when it quotes and records fees; the DEX may change its actual fee. [VERIFY: Minswap's documentation states its batcher fee was removed in 2025; Surge still quotes and records 2 ADA. Confirm against a live swap.]
MuesliSwap appears in some lists but is not tradeable; selecting it fails.
What “parks until you cancel” means
On SundaeSwap, WingRiders and Splash, if the market moves past your order's minimum before the batcher gets to it, the order simply stays open at the DEX's order address with your funds inside. Nothing bad happens to the funds, but they are locked until you sign a cancel transaction that returns them to your wallet. Surge:
offers a cancel automatically for grid, rule-based and arbitrage orders that have been open for more than 5 minutes (a "Cancel ready" prompt appears on the strategy page);
shows a Cancel & reclaim funds button on manual swaps and in the wallet detail page once an order has been open for more than 3 minutes.
How Surge picks a DEX
Manual swap: you choose one DEX, or let the aggregator split the swap across several. See Manual swap.
Grid: you choose which DEX's are allowed; Surge prices and trades on the deepest eligible pool among them.
Rule-based: you choose which DEX's are allowed; for each order Surge quotes every allowed venue's deepest pool at your size and fires on the one that pays the most after batcher, network and Surge fees.
Arbitrage: you choose at least two DEX's to monitor; Surge buys on the cheaper and sells on the dearer of any pair.
DCA, Cadence: you choose one DEX.
A pool is only eligible if it holds at least a minimum amount of ADA — 1,000 ADA for price feeds and 5,000 ADA for grid, rule-based and arbitrage trading — so a thin or dust pool is never used.
Token naming
Token symbols and logos come from the DEX token registries. A "verified" badge in the pair picker means the token appears in Minswap's verified-token list. Tokens whose decimal places are unknown are shown but their value is not counted in your portfolio total.
