Quick facts
At a glance
FactAcrossBase Bridge
PricingSnapshotAcross Docs, "Fees in the System" (docs.across.to/introduction/fees, fetched 30 September 2026): the whole fee is the spread, "totalFee = inputAmount - outputAmount", split into an LP Fee (utilization-based, Aave-style two-slope curve, per route) and a Relayer Fee covering destination gas, capital opportunity cost and capital at risk; "If the relayer takes repayment on the origin chain (same chain as the deposit), no crosschain rebalancing is needed, so LP fees are zero." No headline percentage is published. Integrators may add an app fee on top ("Set appFee (a decimal from 0 to 1 , e.g. 0.01 = 1%) and appFeeRecipient on your Swap API request."). Measured the same day on app.across.to/api/suggested-fees for 1000000000 USDC base units (six decimals) Ethereum to Arbitrum: "outputAmount":"999892297", "capitalFeeTotal":"100000", "relayGasFeeTotal":"7703", "lpFeePct":"0", "estimatedFillTimeSec":2 (arithmetic: 1000000000 - 999892297 = 107703 base units, about 1.08 bps of the amount sent, plus origin-chain gas that the endpoint does not return).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.
