Across vs. Hyperliquid
Rift Research
Last updated
TLDR: Across is an intent-based interoperability protocol. Hyperliquid is an onchain L1 orderbook for spot and perps. Consider Across when you are moving canonical USDC or ETH between major chains and care about speed. Consider Hyperliquid when you are trading spot or perps once assets are on Hyperliquid.

What each protocol is
Across. Across is an intents protocol for bridging and cross-chain swaps. Relayers front destination liquidity. Across advertises approximately two-second fills on supported mainnet routes; actual timing depends on the route. Its intent settlement and refund mechanisms are separate from that initial fill. Official docs: Across Docs. App: across.to.
Hyperliquid. Hyperliquid is an L1 with an onchain central-limit orderbook (HyperCore) and a general-purpose EVM (HyperEVM). It is a destination trading venue. Bridging assets onto it is a separate step. Official docs: Hyperliquid Docs. App: app.hyperliquid.xyz.
Short version
| Dimension | Across | Hyperliquid |
|---|---|---|
| Role | Intent-based interoperability protocol | Onchain L1 orderbook (spot and perps) |
| Fee | Market-quoted relayer spread and LP fee; no separate flat protocol toll | Spot and perp maker/taker schedule on Hyperliquid |
| Coverage | Supported mainnet networks, with availability determined by the exact token pair and route | Hyperliquid L1: HyperCore spot and perps, plus HyperEVM (EVM chain ID 999) |
| Settlement | Canonical assets delivered by bonded relayers | On the Hyperliquid orderbook / HyperEVM |
| Trust model | Relayer-funded fills and the settlement and dispute mechanisms of the deployed Across contracts | HyperBFT validator set |
| Good fit for | Canonical USDC and ETH transfers between supported chains | Trading spot and perps once assets are on Hyperliquid |

Where each fits
Across may fit when:
- You are moving USDC or ETH between major supported chains
- Fast destination fills matter; confirm the estimate for your route
- You want a dedicated intent rail rather than a meta-aggregator
Hyperliquid may fit when:
- You are already on Hyperliquid and want the orderbook
- The job is trading perps or spot, not bridging
Key differences
Hyperliquid provides spot and perpetual orderbooks on its own chain. Across may handle a swap, transfer or composed action that overlaps with part of that journey. Reaching Hyperliquid and trading there are separate costs unless included in one quote. Compare the full route and spot trading fee; a swap router is not a replacement for every perpetuals or order-management feature.
When to use which
- Use Across when you are moving canonical USDC or ETH between major chains and care about speed.
- Use Hyperliquid when you are trading spot or perps once assets are on Hyperliquid.
- If both can quote the same route, take the better net output after fees, time and settlement type. Check that print on rates.gg.
FAQ
Which is cheaper, Across or Hyperliquid?
Neither has a universal price advantage. Across: Market-quoted relayer spread and LP fee; no separate flat protocol toll. Hyperliquid: Spot and perp maker/taker schedule on Hyperliquid. Compare executable quotes for the same size, destination and time window, including gas, underlying venue costs and any extra transfer. Expected output and minimum received are different figures; compare like with like.
Is Across a substitute for Hyperliquid?
They can overlap on parts of a spot-trading journey. Hyperliquid also offers native orderbook and perpetuals features that a transfer or aggregation API does not replace. Compare the full deposit, trade and withdrawal workflow.
