FactOptimism GatewayzkSync 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.ZKsync docs, "Bridging assets" (docs.zksync.io/zksync-protocol/rollup/bridging-assets, fetched 30 September 2026): no bridge fee is stated on that page; withdrawals carry a time cost - "To provide additional security, withdrawals in ZKsync Chains are delayed for 3 hours" - and the finality page (docs.zksync.io/zksync-protocol/rollup/finality) adds that proof generation "typically takes about an hour". The ZKsync Bridge front end (portal.zksync.io/bridge, titled "ZKsync Bridge | Transfer funds between ZKsync and Ethereum") renders client-side, so no live 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.
