The math
Five Swaps vs. One Multi Swap
Building a five-token basket the old way means five approvals, five transactions, and five gas fees. Multi Swap collapses that into a single signed transaction on Base.

Questions, answered
What is Multi Swap on Base?
Multi Swap is a MasterDEX flow on the Base network that lets you spend one input asset and receive up to five different tokens in a single transaction. It's a one-click way to build a basket, rebalance, or top up several positions without doing five separate swaps.
Why only Base?
Base offers fast finality and low fees, which makes bundled multi-output swaps cheap and snappy in practice. We're starting on Base so the basket UX feels instant; additional chains are on the roadmap.
How much gas do I actually save?
Combining five separate swaps into one bundled transaction typically saves around 70–80% of the gas you'd pay doing them individually. The exact savings depend on the routes used per output and current Base network conditions.
Is Multi Swap non-custodial?
Yes. MasterDEX never holds your funds. You approve the input token (if needed), preview each output's quote, and sign the transaction yourself from your own wallet. The basket settles directly to your address.
Can I adjust how much of each output I get?
Absolutely. Every output has its own percentage slider. Move one and the others rebalance so the basket always sums to 100% of your input amount.
What if a single output's route fails?
Each leg shows a live quote and a minimum-received estimate before you sign. If a route can't satisfy your slippage tolerance for an output, the UI flags it so you can adjust the allocation or swap that token for a different one.
