On the Fastest cross-chain bridge quote API, live ms ranking benchmark, Relay leads at 953 ms versus Socket Protocol at 1.76 s. Live measurement is updated continuously by the OpenChainBench harness.
On the Cheapest cross-chain bridge for USDC at $300 notional benchmark, Socket Protocol leads at 0.33% versus Relay at 2.61%. Live measurement is updated continuously by the OpenChainBench harness.
Every benchmark on this page uses the same open methodology, published at https://openchainbench.com/methodology. Data is CC-BY-4.0. Measurement harnesses are MIT-licensed.
A pair is published when all four conditions hold. Both providers run in the same OpenChainBench benchmark for at least seven consecutive days. Each provider has at least 1000 samples in the measurement window. The head to head query has observable third party search demand. Both providers have a public /products/[slug] page on OCB. The full pair ledger is versioned in the public repo so the methodology is externally verifiable.
