What makes a corridor "good"
Three properties, in order of impact: destination liquidity (a thin pool on the far side quietly taxes every arrival), bridge competition (corridors with three or more active bridges price near zero), and gas profile (routes avoiding Ethereum mainnet skip its fee entirely). The busiest corridors score well on all three — which is exactly why they're busiest.
The corridor table
| Corridor | Typical Time | Typical All-In Cost | Liquidity |
|---|---|---|---|
| Ethereum → Base | 2 – 10 min | Low (mainnet gas dominates) | Excellent |
| Ethereum → Arbitrum | 2 – 15 min | Low | Excellent |
| Ethereum → Optimism | 2 – 15 min | Low | Very good |
| Arbitrum → Base | 1 – 5 min | Very low | Very good |
| Base → Arbitrum | 1 – 5 min | Very low | Very good |
| Ethereum → Polygon | 3 – 15 min | Low | Good |
| Polygon → Ethereum | 5 – 30 min | Low | Good |
| Optimism → Base | 1 – 5 min | Very low | Good |

Corridor notes
Ethereum → Base
The stablecoin superhighway. USDC flows here are the deepest in the ecosystem, several bridges compete at zero headline fee, and Base's destination liquidity absorbs six-figure arrivals without a blink. The only real cost driver is source gas on mainnet — bridge in the off-peak hours and this is as good as cross-chain gets.
Ethereum → Arbitrum
The DeFi mainstay. Arbitrum's liquidity across ETH, USDC and USDT is the deepest of any L2, which makes this the default corridor for anyone heading to serious trading venues. Slippage at size is the lowest in the industry; the corridor tolerates five-figure transfers without visible impact.
Polygon → Ethereum
The return leg. Cheapest in the reverse direction's shadow — heading into mainnet costs destination gas on the most expensive chain in the ecosystem, and timing matters more. Consolidating funds back to mainnet? Batch it: gas is flat regardless of size, so one $10,000 transfer beats ten $1,000 ones by 90%.
Route selection checklist
- Prefer L2 → L2 when both ends have the apps you need — you skip mainnet gas twice.
- Prefer stablecoin pairs over volatile pairs for the transfer leg; swap after arrival.
- Check the minimum received, not just the headline output — it's the corridor's honest self-assessment.
- If the quote looks too good on a thin corridor, it usually means a thin destination pool — the landing, not the quote, is where you'd feel it.
Timing tip: Ethereum gas bottoms out during US evening hours and Asian mornings. Weekend corridors are calmer still. The aggregator re-prices continuously, but the underlying gas rhythm is predictable enough to plan around.
