Synthetic Pairs on Kraken Pro changes that.
The problem with two-hop routing
When native order books are thin or missing entirely, traders have historically routed through an intermediary (typically USD, USDT, or another liquid asset) to get where they need to go. Two orders, two execution windows, two fees.
The operational overhead is manageable. The execution risk is not. Between the first and second leg, the market moves. Slippage compounds. And the trader absorbs the cost of a structural gap that shouldn’t exist.
This isn’t a niche problem. Altcoin-to-altcoin conversions, AUD corridors, low-liquidity local fiat pairs: these are everyday routing challenges for active traders operating outside deep USD books.
What Synthetic Pairs do
Synthetic Pairs route both legs of the trade through Kraken’s deepest underlying order books and execute them atomically inside the matching engine. From the trader’s perspective, it looks and behaves like a single native trade: one order, one fill, one position, one fee.
The routing, sequencing, and liquidity aggregation happen behind the scenes. Traders interact with a unified market surface; no asset switching, no intermediate positions, no second confirmation.
An “S” indicator appears next to any pair drawn from a synthetic market, and each synthetic trade is recorded as a single entry in account history.
How it works in practice
Say you want to trade SOL for DOGE. There’s no native SOL/DOGE order book with meaningful depth. With Synthetic Pairs, Kraken routes the order through SOL/USD and DOGE/USD (the two deepest underlying books) and settles it as a single SOL/DOGE transaction. You see one trade. You pay one fee.

Order types and price protection
Synthetic Pairs support both market and limit orders.
Market orders carry the same Market Price Protection (MPP) as the base asset’s native pair. If you trade BTC/AUD synthetically, the same MPP threshold applies as BTC/USD; your order won’t execute beyond that threshold, protecting against excessive price impact during volatile conditions.
Limit orders work differently from native pairs: synthetic limit orders don’t rest in the order book. Instead, the engine continuously monitors the underlying books and executes when there’s sufficient depth to fill at your limit price or better.
Trade smarter, route less
Synthetic Pairs is now live on Kraken Pro. Active traders who regularly navigate fragmented liquidity (whether in altcoin corridors, local fiat markets, or cross-asset conversions) now have a structurally cleaner way to execute.
One trade. One fee. No manual routing required.
