Relay vs. 1inch
Rift Research
Last updated
TLDR: Relay is a cross-chain intents and payments protocol. 1inch is a DEX aggregator and execution stack. Consider Relay when you need fast small-to-mid transfers and payments across many networks. Consider 1inch when you want onchain liquidity aggregation across supported sources. Confirm the live winner on rates.gg.
What each protocol is
Relay. Relay is a cross-chain intents protocol. Users deposit into a per-chain Depository; solvers fill on the destination; a dedicated settlement chain and oracle reimburse the solver. Official docs: Relay Docs. App: relay.link.
1inch. 1inch is a long-running DEX aggregator. Pathfinder splits routes across on-chain liquidity. Fusion and Fusion+ add intent-style and cross-chain execution. The business portal exposes swap, orderbook and fusion APIs. Official docs: 1inch Portal Docs. App: app.1inch.io.
Short version
| Dimension | Relay | 1inch |
|---|---|---|
| Role | Cross-chain intents and payments protocol | DEX aggregator and execution stack |
| Fee | Solver spread plus small protocol components, quoted per order | Path-dependent: underlying pools plus any interface or Fusion components |
| Coverage | Networks and assets supported by the selected Relay route | Major EVM chains plus Solana on current 1inch portal docs |
| Settlement | Solver fronts destination liquidity; protocol settles after proof | On-chain via the 1inch router, or Fusion resolvers |
| Trust model | Non-upgradable Depository contracts; Allocator-authorised withdrawals; audited settlement stack | 1inch router and limit-order contracts plus underlying pools |
| Good fit for | Fast small-to-mid transfers and payments across many networks | Onchain liquidity aggregation across supported sources |

Where each fits
Relay may fit when:
- Speed on a small or mid-size transfer matters most
- You need a long list of networks from one integration
- The job is a payment or simple transfer, not a multi-step DeFi action
1inch may fit when:
- The supported same-chain or cross-chain product fits your route
- Split routing across DEXs reduces impact on a large ticket
- You already integrate 1inch Fusion or the Pathfinder API
Key differences
Relay and 1inch should be compared on the job you need to complete: the input asset, destination asset and chain, trade size, execution method and custody assumptions. They may overlap on some routes and complement each other on others. A broader chain list or faster advertised fill does not establish a better net rate. Compare executable quotes in the same window, including gas and every underlying step.
When to use which
- Use Relay when you need fast small-to-mid transfers and payments across many networks.
- Use 1inch when you want onchain liquidity aggregation across supported sources.
- 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, Relay or 1inch?
Neither has a universal price advantage. Relay: Solver spread plus small protocol components, quoted per order. 1inch: Path-dependent: underlying pools plus any interface or Fusion components. 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 Relay a substitute for 1inch?
Only on overlapping pairs and chains. When both can quote the same route, take the better net output after fees and time. When only one supports the asset or chain, that one is the only option.

Get the Best of Both With Rift
Rift is a strong alternative to choosing a single provider. Its rate comparison includes Relay and 1inch alongside additional venues, while the Rift API routes orders across its supported execution integrations. You can compare both approaches and get one execution flow for the available route.
Rift adds no router fee and uses secure hardware enclaves to enforce noncustodial execution. Underlying venue fees, spreads and network costs still apply, and availability depends on the asset, chain and order size. The live quote shows the route and expected output.
