Quick facts

FactSynapseSquid Router
PricingSnapshotNo Synapse price could be read on 30 September 2026. The Synapse REST API (api.synapseprotocol.com), which its docs page docs.synapseprotocol.com/docs/Bridge/REST-API describes as the way to "retrieve quotes", returned "No bridge routes found" for USDC Ethereum to Arbitrum, Ethereum to Optimism and Arbitrum to Base and for ETH Ethereum to Arbitrum and Arbitrum to Optimism, and its /bridge/v2 endpoint returned "An unexpected error occurred in /bridge/v2. Please try again later." The Synapse docs pages read (Bridge, REST API, Supported Routes, Synapse Intent Network, contract pages) publish no fee rate, so the percentage the previous note carried is not repeated.Squid docs, "Transaction times and fees" (docs.squidrouter.com/additional-resources/architecture/transaction-times-and-fees, fetched 30 September 2026; the page reads "Last updated 6 months ago"): "Squid currently charges no fees. The user will only pay gas fees on source and destination chains." Integrators may add their own fee: "Partners can elect a % fee they would like to charge, and Squid will receive a portion of this fee." Routes with a destination swap also pay Axelar relayer gas in the source-chain token ("This fee is paid to Axelar's relayers, who trustlessly pass messages and proofs across chains."). Squid's homepage (squidrouter.com) advertises "Avg total cost $0.02 $0.10" (Squid versus others), "Based on a $100 ETH transaction from Ethereum mainnet." The swap-leg percentage and relay-cost range the previous note carried are on neither page.

Score dimensions
weights sum to 86
The published score is five dimensions, each weighted for the category. "Published criteria" is the criteria block above; the other four are the engine's own terms — availability, friction, trust record, measured data. Each bar is one side's points out of that dimension's maximum; the weight beside the name is its points of the 86-point weighted total. The published criteria above can fill 24 of the block’s 30. A weight marked “constant here” belongs to a dimension every ranked product in the category holds at the same value: it still counts in the total, and it orders nothing here.
