FactArbitrum BridgezkSync Bridge
Bridge feeSnapshotArbitrum docs, "Quickstart: Arbitrum bridge" (docs.arbitrum.io/arbitrum-bridge/quickstart.md, fetched 30 September 2026): no bridge fee is stated on that page; the user pays gas - "You’ll need the native currency of the parent chain to bridge your assets to the destination chain." A withdrawal needs a second, parent-chain transaction after the challenge period: "Upon confirmation (about one week later), you can execute them" (docs.arbitrum.io cross-chain messaging page). No dollar cost is published on either page, so the deposit and withdrawal 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.
