Quick facts
At a glance
FactSynapseBungee
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.Bungee's documentation link (docs.bungee.exchange) now resolves to Socket's docs. Socket, "Fees & Monetization" (docs.socket.tech/about/fees-monetization, fetched 30 September 2026): "For users, Socket does not charge any additional fees. All onchain execution costs are covered within the quoted fees. Socket does not add any markup or hidden fees to transactions." Integrators may charge their own fee ("integrations are free to implement fee charging for their own services"). The Bungee front end (bungee.exchange) renders client-side and now titles itself "Bungee | Infinite ways to play the market", so no live Bungee quote was read.

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.
