Relay vs. SwapKit

TLDR: Relay is a cross-chain intents and payments protocol. SwapKit is a native cross-chain aggregator. Consider Relay when you need fast small-to-mid transfers and payments across many networks. Consider SwapKit when you want one interface over several native cross-chain protocols. 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.

SwapKit. SwapKit aggregates native cross-chain protocols (THORChain, Chainflip, Mayan, Garden, NEAR Intents and others) plus same-chain DEX routing, behind one API and SDK. Official docs: SwapKit Docs. App: swapkit.dev.

Short version

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

SwapKit may fit when:

• You want THORChain, Chainflip, Garden, Mayan and NEAR Intents behind one quote
• Native settlement is a hard requirement
• You are integrating a widget or Partner API rather than a single venue

Key differences

Relay and SwapKit 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 SwapKit when you want one interface over several native cross-chain protocols.
• 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 SwapKit?

Neither has a universal price advantage. Relay: Solver spread plus small protocol components, quoted per order. SwapKit: SwapKit fee band of 0.15% / 0.12% / 0.10% by size, 0.01% stable-to-stable, plus the underlying venue fee. 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 SwapKit?

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 between Relay and SwapKit. It brings routes from both together with additional venues on supported pairs, comparing available quotes to find the best net execution for your order. You get the strengths of both through one API.

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.
