PricingSnapshotScroll 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."Symbiosis docs, "Symbiosis & Fees" (docs.symbiosis.finance/main-concepts/symbiosis-and-fees.md, fetched 30 September 2026): the user pays source-chain gas - "The user signs and submits this transaction on the source blockchain (where their assets are held) and covers the gas fee for this transaction." - and the gas that Symbiosis relayers spend on the S-chain and the destination chain is withheld from the swapped tokens as a stablecoin-equivalent estimate; the FAQ (docs.symbiosis.finance/faq.md) puts it as "relayers pay for the gas, which is deducted from users swaps". Octopool swap fees and slippage apply on top. No percentage fee is published on either page, so the percentage the previous note carried is not repeated.

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.
