swaps.xyz

swaps.xyz, branded on its own site as MoonPay Trade, is the routing infrastructure behind apps that let a trader open a Polymarket position from any token on any chain in a single call. It doesn't run as its own trading terminal or wallet; instead it's an API and set of contracts that other wallets and apps, such as Trust Wallet, integrate to expose Polymarket order placement without first requiring the trader to hold Polygon-native USDC.

Its documentation describes it as the execution layer for swaps, bridges, cross-chain contract calls, and prediction market trading behind one API, with a dedicated integration path that collapses the usual swap-then-bridge-then-trade sequence into a single call from any source token to a placed order. A trader typically meets it inside whichever app has integrated it rather than on swaps.xyz itself.

A trader doesn't connect to swaps.xyz directly; they meet it inside an integrating wallet or app, such as Trust Wallet, that has wired up the Polymarket flow. The trader picks a source token on whatever chain they already hold it on, and the app calls Swaps' getAction endpoint to build a single transaction.

That transaction can swap, bridge, and place the Polymarket order in one broadcast. The documentation calls this a destination action, meaning the mint, deposit, or order lands on the target chain inside the same flow rather than as a separate step the trader has to trigger afterward. Gasless execution on supported chains means the trader doesn't need to hold a separate gas token before the trade goes through, and stablecoin legs route through Swaps' own stable-pair liquidity rather than a general-purpose automated market maker.

The infrastructure itself never takes custody. Transactions are constructed for the trader's own wallet to sign and broadcast, and the deposit addresses it issues are described as persistent, with no exchange sitting between the trader and the destination chain.

• Any-token entry to Polymarket

  One getAction call swaps, bridges, and places the order together, so a trader can open a position from a token on another chain without a separate bridge step first.

• Gasless trade execution

  Trades go through without the trader holding a separate gas token, removing a step that otherwise blocks a first-time cross-chain trade.

• Destination actions in one transaction

  Minting, depositing, or placing the order on the destination chain happens inside the same transaction as the swap or bridge, instead of a manual follow-up step.

• Persistent deposit addresses

  Addresses are dedicated per trader with no exchange step in the middle, which shortens the path funds travel before reaching the destination chain.

Traders holding assets off Polygon

Lets them open a Polymarket position straight from a token on another chain, skipping a manual bridge and swap first.

Traders without gas on hand

Gasless execution covers the trade even when the trader hasn't set aside a separate token to pay for it.

Mobile wallet users

Reaches Polymarket through whichever wallet has integrated the flow, such as Trust Wallet, rather than a standalone terminal.

Traders opening from stablecoins

Stablecoin legs route through dedicated stable-pair liquidity, useful for a trader moving in and out of cash-like assets.

Traders tracking bitcoin markets

The largest routed category is bitcoin, and Will the price of Bitcoin be above $66,000 on August 19 drew the largest share of routed volume over the last month.

Traders entering more than exiting

Buy share of routed volume sits at 87%, so the flow skews toward opening positions rather than closing them.

swaps.xyz doesn't publish a fee schedule; the operator states no rate for what routing an order through it costs beyond the mechanics its documentation lays out. Because a trade here often bundles a swap or bridge leg into the same call that places the Polymarket order, a trader should check that leg's pricing before signing, since moving value across chains and through a stablecoin pair can add a spread on top of whatever the destination market charges. Polymarket's own trading fee is set per market and applies the same way no matter which builder routes the order, so it isn't a cost this tool sets and not a point of difference against another builder. Absent a published number, the only way to know the all-in cost of a trade is to read the quote before confirming it.

• Lets a trader open a Polymarket position directly from a token on another chain, cutting the manual bridge-then-swap sequence to one call.
• Removes the need to pre-fund a wallet with a separate gas token, since execution is gasless on supported chains.
• Bundles the deposit or order placement into the same transaction as the swap or bridge, rather than leaving it as a follow-up step.
• Never takes custody of trader funds, since transactions are constructed for the trader's own wallet to sign and broadcast.
• Has logged 140 of routing history since its first attributed fill, long enough to have crossed more than one market cycle.
• Holds a verified profile on Polymarket, adding a basic layer of platform-side transparency.

• Publishes no fee schedule, so the all-in cost of a cross-chain entry only shows up in the quote at the moment of the trade.
• Runs as infrastructure rather than a standalone app, so a trader depends on whichever wallet or product has integrated it, such as Trust Wallet, for the interface.
• Recent daily trader counts sit at 2 against a thirty-day cohort of 20 wallets, a narrow base for judging how crowded the flow is.
• Weekly routed volume (-92.1%) shows how quickly activity can thin out from one week to the next.
• Buy share of 87% means the flow leans toward opening positions, so a trader planning to exit through it should expect thinner support.

The infrastructure itself never holds trader funds; transactions are built for the trader's own wallet to sign and broadcast, and the deposit addresses it issues are described as persistent, with no exchange sitting between the trader and the destination chain. It carries a verified profile on Polymarket, a basic layer of platform-side transparency. The operational exposure sits in the routing itself: a single call can chain a swap, a bridge, and an order placement together, so a trader's actual exposure depends on the cross-chain contracts and the integrating wallet, such as Trust Wallet, that surfaces the flow, not on swaps.xyz alone.

swaps.xyz suits a trader who holds funds outside Polygon USDC and wants one transaction that swaps, bridges, and opens a Polymarket position together, especially through an integrated app like Trust Wallet. The case for it rests on that cross-chain convenience and on gasless, non-custodial execution rather than on a published price, since the operator states none. A trader already sitting on Polygon with USDC ready has less to gain from the extra routing layer, and anyone who wants a fee number before committing should read the quote closely first. It currently ranks #30 by attributed volume, averaging $730 per fill.

• Is swaps.xyz a Polymarket wallet or trading app?

  No. It's routing infrastructure that other wallets and apps, such as Trust Wallet, integrate to let a trader open a Polymarket position from any token on any chain.

• Does swaps.xyz charge a fee?

  The operator states no rate for using it. A trader should read the quote an integrating app shows before confirming, since a swap or bridge leg can add its own cost.

• Does swaps.xyz hold my funds?

  No. Transactions are constructed for the trader's own wallet to sign and broadcast, and it describes its deposit addresses as persistent with no exchange in the middle.

• Can I trade Polymarket without gas or Polygon USDC?

  Yes, on supported chains. Gasless execution and one-call routing let a trader enter a position from a token on another chain without pre-funding gas or bridging first.

• How does swaps.xyz differ from trading on Polymarket directly?

  It adds a cross-chain routing step ahead of the order rather than replacing Polymarket's own order book, useful mainly when a trader's funds sit on a different chain.

• Where does swaps.xyz rank among Polymarket builders?

  It sits at #30 by all-time attributed volume, having routed $28.7M since its first attributed fill on 2026-04-28, with the index's figures current through 2026-09-14.
