0x0debb5b45680834ad97e99f6a4730791f5cf731237ac1bcf9fb1247254998322 Swaps.xyz is a cross-chain routing API built by Decent (acquired by MoonPay in mid-2025) that aggregates best-execution quotes across 200+ blockchains. As a Polymarket builder, swaps.xyz lets users seamlessly fund and trade on prediction markets directly from their wallet using any token on any supported chain, not just USDC on Polygon. On the Polymarket Builder leaderboard it sits at #18 by 30-day volume with $5.12M routed, #23 all-time at $14.35M cumulative, and serves 577 monthly active users (2,687 lifetime) — placing it in the strong-retail tier. Decent was founded in 2021 by Charlie Durbin, Will Collier, Will Kantaros, and Xander Carlson, backed by Y Combinator, Archetype, and Circle (~$5M raised). MoonPay acquired Decent in May 2026 for a 'high eight-figure' sum and folded the routing engine into MoonPay Trade. There are no end-user fees layered on top of underlying network and venue costs.
Swaps.xyz is the user-facing brand of Decent's cross-chain routing infrastructure: 'the cross-chain decent API: 200+ chains and best quotes in all of crypto,' as the site puts it. The product is a single API that abstracts away bridging, swapping, and execution across 200+ blockchains, so a user holding any token on any chain can fund a Polymarket trade — settled on Polygon USDC — without manually bridging.
On the Polymarket Builder leaderboard, swaps.xyz currently ranks #18 by 30-day volume ($5.12M routed) and #23 all-time ($14.35M cumulative). It is one of the few builders in this tier with a genuinely retail-shaped user base: 577 monthly active users and 2,687 lifetime users — orders of magnitude higher than the institutional-flow builders ranked above it, which suggests swaps.xyz is doing what the Polymarket Builder Program was designed for (lowering the funding-friction barrier for marginal traders).
Decent was founded in 2021 by Charlie Durbin, Will Collier, Will Kantaros, and Xander Carlson and went through Y Combinator. Investors include Archetype, Circle, AngelDAO, and CoinList, with roughly $5M raised. In May 2026 MoonPay acquired Decent for a 'high eight-figure' sum and rolled the routing engine into the newly launched MoonPay Trade platform, which targets banks and institutions integrating onchain liquidity across more than 200 chains.
For Polymarket itself, swaps.xyz matters because it's one of the few builders whose product has been independently validated by an institutional acquirer — MoonPay didn't buy Decent for its prediction-market footprint, but the same cross-chain rails that power swaps.xyz now sit inside MoonPay Trade.
Verification: URL redirects to decent.xyz on its homepage, which carries the same exact tagline; Decent's docs at docs.swaps.xyz confirm the prediction-market integration. Acquisition confirmed via The Block, PitchBook, and PRNewswire.
