Every crypto transaction starts from one of two places: you either already hold a token and want to turn it into another one, or you're starting from regular money, dollars, euros, pounds, and want to get into crypto for the first time. These sound similar, but under the hood they're solved by completely different plumbing. That's why Edge Rates is split into two sections, Swap and Matrix, instead of trying to force both journeys through a single form.
What Swap actually compares
Swap is for the case where you already hold a crypto asset and want to convert it, same chain or a different one entirely. Under the hood it queries live route quotes across decentralized exchanges and bridges, then lines up two things side by side: the route that gets you the most tokens back, and the route that gets there fastest. Those aren't always the same path. A route through more hops might squeeze out a slightly better rate but take several minutes longer; a direct route might be near-instant but leave a bit more on the table.
Because this side of the tool is non-custodial by nature, comparing routes never requires connecting a wallet, you only need one when you're ready to actually execute a route on Edge Swap. The number that matters most here is the minimum received: the worst-case amount you're guaranteed to get once slippage and the platform's visible 0.25% fee are accounted for.
What Matrix actually compares
Matrix solves the opposite problem: you're holding fiat, not crypto, and want to know which on-ramp provider gives you the most coin for your money. Rather than showing a single rate, it compares live quotes across providers for the same fiat amount and the same target coin, so the difference in the final crypto amount you'd walk away with is visible upfront, not buried in a rate you'd only discover at checkout.
Just like Swap, no wallet connection is needed to compare quotes on Matrix. The actual purchase happens on the provider's own checkout once you pick a result, which is also where any KYC requirements come in, usually only above certain purchase thresholds, and it varies provider by provider.
A simple way to decide
The fastest way to know which section you need is to ask what's sitting in your wallet right now. If it's already crypto and you want a different crypto, same chain, different chain, doesn't matter, that's Swap. If what you're holding is fiat currency and crypto hasn't entered the picture yet, that's Matrix. Plenty of people end up using both in the same session: buying an entry asset through Matrix, then using Swap to route it into whatever token or chain they actually needed in the first place.
Why this split replaced Edge Bridge and Edge Fees
Swap and Matrix aren't new ideas, they carry forward exactly what Edge Bridge and Edge Fees did separately. Splitting cross-chain comparison and fiat on-ramp comparison into two standalone tools made sense when they were simpler, but it also meant checking two different pages for what is, at the end of the day, the same underlying question: "what's the best way to get from what I have to what I want?" Merging them into Edge Rates keeps both comparisons live, side by side, without asking you to remember which tool did which job.
