FactArbitrum BridgeBase 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.Base docs (fetched 30 September 2026): the canonical deposit path pays gas only - "They buy their L2 gas on L1 and, as such, the L2 gas is not refundable." (docs.base.org/specifications/base-protocol/bridging/deposits). Base no longer runs its own bridge interface: its "Bridge to Base" page (docs.base.org/base-chain/network-information/ecosystem-bridges) sends Ethereum users to "Superbridge or Brid.gg" and Coinbase-account holders to "Withdraw directly to Base (no bridge)". The previous pricing page, docs.base.org/use-base/bridge, now returns HTTP 404. No bridge fee is stated on the pages 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.
