FactOptimism GatewayScroll Bridge
Bridge feeSnapshotOP 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.Scroll docs, "ETH and ERC20 Token Bridge" (docs.scroll.io/en/developers/l1-and-l2-bridging/eth-and-erc20-token-bridge, fetched 30 September 2026): no bridge fee is stated on that page; the ETH sent with a deposit pays the L2 execution fee and with a withdrawal the L1 fee, excess refunded - "0.00001 ETH should be more than enough to process a token deposit." and "Fees will depend on L1 activity but 0.005 ETH should be enough to process a token withdrawal." The same page warns: "There is no way to recover bridged ETH, tokens, or NFTs if your transaction reverts on L1."

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.
