Relay vs. Socket (Bungee)
Rift Research
Last updated
TLDR: Relay is a cross-chain intents and payments protocol. Socket (Bungee) is a multi-bridge and swap routing engine. Consider Relay when you need fast small-to-mid transfers and payments across many networks. Consider Socket (Bungee) when you need embedded cross-chain UX and multi-bridge coverage.

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.
Socket (Bungee). Socket is the routing engine. Bungee is the product surface (app, widget, API) built on Socket. Together they quote same-chain and cross-chain routes across bridges and DEXs, including deposit-address flows for non-EVM destinations. Official docs: Socket Docs. App: bungee.exchange.
Short version
| Dimension | Relay | Socket (Bungee) |
|---|---|---|
| Role | Cross-chain intents and payments protocol | Multi-bridge and swap routing engine |
| Fee | Solver spread plus small protocol components, quoted per order | Route quote includes underlying venue costs and any affiliate / integrator fee |
| Coverage | Networks and assets supported by the selected Relay route | Supported Bungee/Socket routes, including selected non-EVM deposit flows |
| Settlement | Solver fronts destination liquidity; protocol settles after proof | Depends on the selected bridge or DEX route |
| Trust model | Non-upgradable Depository contracts; Allocator-authorised withdrawals; audited settlement stack | Socket contracts plus each underlying bridge |
| Good fit for | Fast small-to-mid transfers and payments across many networks | Embedded cross-chain UX and multi-bridge coverage |

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
Socket (Bungee) may fit when:
- You want a widget, link or API embed rather than a single bridge
- The route is EVM-to-EVM or a supported deposit-address flow
- Destination payload execution after the bridge is useful
Key differences
Relay and Socket (Bungee) 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 Socket (Bungee) when you need embedded cross-chain UX and multi-bridge coverage.
- 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 Socket (Bungee)?
Neither has a universal price advantage. Relay: Solver spread plus small protocol components, quoted per order. Socket (Bungee): Route quote includes underlying venue costs and any affiliate / integrator 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 Socket (Bungee)?
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.
Where are the official Relay and Socket (Bungee) docs?
Relay: Relay Docs. Socket (Bungee): Socket Docs. Live rate comparison: rates.gg.

Get the Best of Both With Rift
Rift is a strong alternative to choosing between Relay and Socket (Bungee). 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.
