Split decision: Relay leads on Fastest cross-chain bridge quote API, live ms ranking (339 ms vs 1.50 s); Socket Protocol leads on Cheapest cross-chain bridge for USDC at $300 notional (0.012% vs 0.058%).
Cross-chain intent network from Reservoir. Users sign an intent, relayers compete to fill on the destination, settlement is typically sub-30 seconds.
Cross-chain interoperability protocol and bridge aggregator. The Socket API routes bridging and swap transactions across major EVM chains via underlying bridges including Across, Stargate, and CCTP.

On the Fastest cross-chain bridge quote API, live ms ranking benchmark, Relay leads at 339 ms versus Socket Protocol at 1.50 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 0.012% versus Relay at 0.058%. 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.
Auto-generated pairs require: both providers in the same benchmark for seven consecutive days, at least 1000 samples per provider, observable third-party search demand, and a public /products/[slug] page on OCB. Editorially curated pairs (like this one) may publish early when search demand is high and data is accruing — panels with fewer than 100 samples are shown as provisional. The full pair ledger is versioned in the public repo.
