FactOptimism GatewaySymbiosis
PricingSnapshotOP docs, "Using the Standard Bridge" (docs.optimism.io/app-developers/guides/bridging/standard-bridge, fetched 30 September 2026): no bridge fee is stated on that page; the cost is gas, set per transfer as "_minGasLimit : Gas to use to complete the transfer on the receiving side." Deposits "are usually completed within 1-3 minutes" and withdrawals "are completed in 7 days as a result of the withdrawal challenge period", with a prove and a finalize transaction on Ethereum. No dollar cost is published on the page, so the dollar ranges the previous note carried are not repeated.Symbiosis docs, "Symbiosis & Fees" (docs.symbiosis.finance/main-concepts/symbiosis-and-fees.md, fetched 30 September 2026): the user pays source-chain gas - "The user signs and submits this transaction on the source blockchain (where their assets are held) and covers the gas fee for this transaction." - and the gas that Symbiosis relayers spend on the S-chain and the destination chain is withheld from the swapped tokens as a stablecoin-equivalent estimate; the FAQ (docs.symbiosis.finance/faq.md) puts it as "relayers pay for the gas, which is deducted from users swaps". Octopool swap fees and slippage apply on top. No percentage fee is published on either page, 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.
