PricingSnapshotRe-read 28 October 2026 (docs.debridge.com/dln-details/overview/fee-structure): "Flat fee – a fixed amount in the source‑chain native token paid to deBridge validators for processing the eventual unlock message."; "Taker margin (≈ 4 bps) – the solver’s profit."; worked example "Flat fee: 0.001 ETH Variable fee: 0.04 % × 1 000 = 0.40 USDC Taker margin: 0.40 USDC Operating expenses: ≈ 0.03 USDC". Earlier read: deBridge docs, "Fee Structure" (docs.debridge.com/dln-details/overview/fee-structure, fetched 30 September 2026): two order-creation fees - "Flat fee - a fixed amount in the source-chain native token paid to deBridge validators for processing the eventual unlock message." and "Variable protocol fee (4 bps) - deducted from the input token." - plus runtime costs built into the spread, "Taker margin (≈ 4 bps) - the solver's profit." and the solver's gas for fulfil, unlock and claim; "Both fees are fully refunded if the order is cancelled." The per-chain table (docs.debridge.com/dln-details/overview/fees-supported-chains.md) lists a flat fee of "0.001 ETH" on Ethereum, Arbitrum, Optimism, Base and Linea and warns "Protocol fees can be changed." On-chain the same day: eth_call DlnSource 0xeF4fB24aD0916217251F553c0596F8Edc630EB66 globalFixedNativeFee() at Ethereum block 26,086,358 returned 1000000000000000 wei (0.001 ETH) and globalTransferFeeBps() returned 4.No 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.

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.
