Why we publish this
SwapZilla is a crypto swap aggregator. We integrate with multiple exchange providers and earn a fee on every swap routed through them. Because we monetize the providers we compare, neutrality matters — the only way our comparisons are useful is if the data behind them is traceable and verifiable.
This page explains exactly how we measure each provider, where the numbers come from, and how often they refresh. Every comparison post on the blog links back here.
What we measure
For each (provider × supported coin) pair, we track these attributes:
- Average execution time — measured median time from deposit confirmation to payout for completed swaps in the trailing 30-day window.
- Rate spread — percentage by which the provider's quoted rate deviates from the cross-aggregator mid-market rate at the moment of quote.
- Min / max swap size — limits as advertised by each provider, expressed in USD-equivalent.
- Account requirement — whether the provider requires registration, KYC, or operates as no-account.
- Supported networks — exact networks each provider supports for the given coin (e.g. ERC-20, TRC-20, BEP-20).
Data sources
Provider lists, supported assets, and KYC flags come directly from each provider's public API and from the SwapZilla quote engine, which queries every provider in real time for every user request.
Performance metrics (execution time, spread) come from the SwapZilla aggregator's own swap history. We do not source these from the providers' marketing pages, because those numbers are commonly out of date or idealized.
We currently track 6 providers. The active list is synced from our backend on every site build, so when a provider is added or paused, comparison pages update automatically on the next deploy.
Refresh cadence
Provider availability and supported coins refresh on every site build (typically several times per week, more often around feature releases). Performance metrics refresh weekly. Each comparison post shows the date its underlying data was last refreshed — this date is separate from the post's publish or edit date.
How we pick winners
Comparison posts label a winner per category — "fastest", "best rate", "no account", "large amounts". These labels are derived algorithmically from the data, not chosen by editors:
- Fastest = lowest
avgTimeMin - Best rate = lowest
rateSpread - No account = lowest spread among providers with no account requirement
- Large amounts = highest
maxSwapUsd
If two providers tie within rounding, we list both as winners.
Disclosure
SwapZilla earns a fee on every swap routed through any of the providers listed in our comparisons. This fee is a flat percentage of the executed swap volume and is the same regardless of which provider the user picks. SwapZilla has no equity stake or revenue-share arrangement that varies by provider.
Providers do not pay to be ranked higher, and we do not exclude providers based on commercial relationships. A provider is listed if and only if it is integrated with the aggregator and currently enabled.
Corrections
If you spot a number that looks wrong on a comparison page, write to [email protected]. We publish corrections within the same week and update the data refreshed date so the change is visible.
