Relay vs. Bebop
Rift Research
Last updated
TLDR: Relay is a cross-chain intents and payments protocol. Bebop is an RFQ and solver-auction DEX. Consider Relay when you need fast small-to-mid transfers and payments across many networks. Consider Bebop when you want tight same-chain RFQ execution or solver-auction coverage. 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.
Bebop. Bebop is on-chain trading infrastructure. The RFQ API returns firm quotes from private market makers. The Aggregation API runs a solver auction across DEXs. Settlement is atomic in audited contracts; Bebop does not custody funds. Official docs: Bebop Docs. App: bebop.xyz.
Short version
| Dimension | Relay | Bebop |
|---|---|---|
| Role | Cross-chain intents and payments protocol | RFQ and solver-auction DEX |
| Fee | Solver spread plus small protocol components, quoted per order | Priced into the RFQ or auction quote (spread / solver pricing) |
| Coverage | Networks and assets supported by the selected Relay route | EVM networks plus Solana on the trading APIs |
| Settlement | Solver fronts destination liquidity; protocol settles after proof | On-chain through Bebop settlement contracts |
| Trust model | Non-upgradable Depository contracts; Allocator-authorised withdrawals; audited settlement stack | Audited settlement contracts; signed orders settle through the deployed contracts, with maker liquidity and contract assumptions |
| Good fit for | Fast small-to-mid transfers and payments across many networks | Tight same-chain RFQ execution and solver-auction 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
Bebop may fit when:
- You need a firm RFQ from market makers on a supported pair
- The trade is same-chain and price impact on an AMM would be high
- You want solver-auction coverage for longer-tail tokens
Key differences
Relay and Bebop 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 Bebop when you want tight same-chain RFQ execution or solver-auction 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 Bebop?
Neither has a universal price advantage. Relay: Solver spread plus small protocol components, quoted per order. Bebop: Priced into the RFQ or auction quote (spread / solver pricing). 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 Bebop?
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 Bebop 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.
