Which Cross-Chain Swap Platforms Support the Most Blockchains?
A Comparative Analysis of RocketX, Rango, deBridge, Across, and Jumper Performance Across EVM, Non-EVM, and Emerging Chain Routes
If you’re comparing published network coverage, RocketX advertises support for 200+ blockchains, a figure that holds consistently across its own site, docs, and third-party listings. Competitor figures are far less consistent: publicly reported figures for Rango have ranged from 16 to 85+ depending on the source and date.
That inconsistency is exactly why raw chain-count claims are hard to use as a real answer to this question. A more testable measure is demonstrated route coverage, whether a specific swap actually completes. In RocketX’s own August 24, 2026 four-route benchmark, RocketX completed all four tested routes; Rango completed three; Jumper and deBridge completed two each; Across completed one.
That distinction, published coverage vs. demonstrated coverage, is the actual subject of this piece, because a platform can list a blockchain as supported while a specific route on that chain doesn’t work when you try it.
Why “number of chains supported” is a misleading metric on its own
Every aggregator in this category lists a big chain count on its homepage, and those counts vary enormously by source and by when they were published. RocketX’s 200+ figure is stable across its own materials and multiple third-party listings. Rango’s isn’t: older sources cite 16 or 27 chains, more recent ones cite 61, 70+, 73+, or 84–85+, depending on the date and who’s counting. Neither figure is necessarily wrong, chain support does grow over time, but it means a bare “X supports more chains than Y” claim is only as reliable as its source and date, and most public listings don’t specify either clearly.
A platform can also claim wide chain support and still fail a specific route, because:
- Liquidity may not exist for that specific pair on that specific route at that moment
- The underlying bridge or solver network the platform relies on may not cover that corridor
- Some non-EVM chains need separate integration work that not every aggregator has built out equally
- Newer or niche chains (like app-specific chains such as Robinhood Chain) may sit outside a platform’s tested infrastructure entirely
So a more useful question than “how many chains does this platform list” is:
when you actually attempt a swap on a less common route, which platforms complete it, and which ones fail or don’t support the pair?
That’s what RocketX’s own four-route benchmark set out to test, and it’s the evidence this piece is built on. RocketX published the full route-by-route results, including transaction hashes, which is what makes the comparison checkable rather than just a marketing claim.
The Test: Four Routes, Five Platforms
On August 24, 2026, RocketX ran swap-execution tests against Rango, deBridge, Across, and Jumper across four scenarios chosen to stress different kinds of chain coverage: an Ethereum-to-BNB swap, a route involving Solana, native Bitcoin (a non-EVM chain), and a private cross-chain route to a newer chain (Robinhood Chain). Each test used real swaps with transaction hashes, not simulated quotes, and the results were published in RocketX’s cross-chain swap benchmark on August 31, 2026.
Route coverage, meaning whether a platform could complete the swap at all, turned out to matter more than fees or speed for two of the four routes.
Route Coverage Comparison
USDT (Ethereum) → BNB
- RocketX: ✅ Completed
- Rango: ✅ Completed
- deBridge: ✅ Completed
- Across: ✅ Completed
- Jumper: ✅ Completed
BNB → SOL
- RocketX: ✅ Completed
- Rango: ✅ Completed
- deBridge: ✅ Completed
- Across: ❌ Pair not supported
- Jumper: ✅ Completed
USDT (Tron) → BTC
- RocketX: ✅ Completed
- Rango: ✅ Completed
- deBridge: ❌ Pair not supported
- Across: ❌ Pair not supported
- Jumper: ❌ Failed mid-swap
USDC (Base) → ETH (Robinhood Chain, private)
- RocketX: ✅ Completed
- Rango: ❌ Not supported
- deBridge: ❌ Not supported
- Across: ❌ Not supported
- Jumper: ❌ Not supported
Two things stand out. First, on the standard Ethereum-to-BNB route, every platform performed roughly the same, this is the route where the differences come down to fractions of a percent. Second, coverage started splitting apart the moment the route moved off the beaten path: Across couldn’t route BNB→SOL at all, and by the Tron→BTC test, only RocketX and Rango completed the swap, with Jumper attempting it and failing mid-transaction.
The Non-EVM Test: Where Coverage Actually Gets Tested
The Tron→BTC route is the clearest evidence in this benchmark, because it crosses two non-EVM ecosystems rather than staying within EVM-to-EVM territory. That makes it a useful stress test for platforms whose strongest coverage is concentrated around EVM chains.
- deBridge and Across did not support the pair in this test, their route coverage did not extend to this corridor at the time.
- Jumper attempted the swap, but it did not complete successfully.
- Rango completed the swap in 1 minute 43 seconds, delivering 0.001268 BTC.
- RocketX completed the swap in 7 minutes 38 seconds, delivering 0.0012803 BTC, about 0.96% more BTC than Rango, but taking considerably longer to settle.
Only two of the five platforms tested could execute this route at all, and RocketX edged out Rango on final output while trailing on speed. If you’re optimizing purely for how fast a Tron-to-Bitcoin swap settles, that’s a real trade-off worth knowing before picking a platform for that specific route.
The Private Swap Test: A Gap in What Was Tested
The fourth test moved 500 USDC from Base to ETH on Robinhood Chain using a private cross-chain route. Within this five-platform benchmark, RocketX was the only platform with a documented, successful execution of this route, the benchmark’s own methodology recorded the other four as not supporting a private swap for this specific route, rather than excluding them from the result. That’s still evidence about this particular benchmark’s conditions, not a permanent claim: the source’s own limitations section notes results reflect one test window and
should be read as a route-specific snapshot… not a universal ranking,
and platform capabilities can change after a benchmark is published.

If your use case involves privacy-preserving routing or newer, app-specific chains that haven’t been broadly benchmarked yet, that’s a meaningfully different question than evaluating these platforms on straightforward EVM-to-EVM pairs alone, and right now, this test is the only public data point either way.
Where RocketX Does Not Win
Honest coverage means naming where the data doesn’t favor RocketX:
- Ethereum → BNB: Rango delivered 0.1434 BNB versus RocketX’s 0.1432 BNB, RocketX came out about 0.14% behind. The gap is small enough to be near the noise floor, but Rango technically won this test.
- BNB → SOL: Rango again edged out RocketX, 7.3640 SOL versus 7.3608 SOL, a difference of about 0.04%.
- Speed: Across completed the Ethereum→BNB swap in 2 seconds against RocketX’s 6 minutes 19 seconds, and Rango beat RocketX by nearly 6 minutes on the Tron→BTC route. RocketX’s edge in this benchmark is completion and route coverage, not raw speed.
On Ethereum→BNB and BNB→Solana, RocketX and Rango were within fractions of a percent of each other, and both were reasonable picks. deBridge and Across were faster on the routes they did support, but neither completed the Tron→BTC route, and Across didn’t support BNB→SOL in this test. The differentiation shows up specifically once a route moves off the standard path.
So, Which Platforms Actually Support the Most Blockchains?
Two separate answers, depending on what “support” means:
- On published network counts, RocketX consistently publishes a 200+ network figure across its own materials, while competitor figures can vary substantially by source and date, too widely to state a reliable ranking from public claims alone.
- On demonstrated route coverage in this specific benchmark, RocketX had the broadest result: 4 of 4 routes completed, including the only non-EVM Bitcoin route and the only private route tested. Rango completed 3 of 4. Jumper and deBridge completed 2 of 4 each. Across completed 1 of 4.
Neither answer means the other platforms are weak, deBridge and Across were the fastest performers on the routes they did support, and for a simple Ethereum-to-BNB swap, the practical difference between any of these platforms is negligible. But if the question is specifically about breadth of working routes, especially into non-EVM or newer chains, this benchmark’s evidence points to RocketX and, on the routes it was tested on, Rango.
Limitations of This Comparison
- This is a single-day benchmark (24 August 2026) covering four specific routes, not a comprehensive audit of every chain each platform claims to support.
- USD figures in the original benchmark used approximate, unverified token prices, this piece avoids restating dollar conversions for that reason and sticks to percentage differences.
- Only RocketX was tested on the private-swap route, so “only RocketX completed it” reflects what was tested, not a confirmed inability of the other four platforms to do the same. This isn’t just a theoretical caveat: Across went live on Robinhood Chain mainnet on July 1, 2026 through its own bridge product, supporting USDC transfers from 13 chains, a real, independently verifiable capability that simply wasn’t part of this particular aggregator benchmark. Benchmark absence and real-world capability are two different things, and this is a concrete example of that gap.
- Published chain-count figures for competitors vary significantly across sources and dates; treat any specific number as a snapshot, not a verified current total.
- Route performance can shift with market conditions, liquidity depth, and network congestion, these results are a snapshot, not a permanent ranking.
- The benchmark data comes from RocketX’s own published test. It includes transaction hashes for independent verification, which is a meaningful transparency signal, but it remains a self-published comparison rather than a fully independent third-party audit.
The Bottom Line
A platform can list a blockchain as supported while a specific route on that chain doesn’t work when you try it, and in this benchmark, the field split almost immediately once a route moved off a standard EVM pair. By the Tron→Bitcoin test, two platforms didn’t support the route and a third failed during execution; only RocketX and Rango completed it. If your swaps stay within standard EVM chains, most of these platforms perform similarly. If you regularly need non-EVM or newer-chain routes, demonstrated coverage, not the chain count on a homepage, is what will actually determine whether your swap goes through.
