Quick facts
At a glance
FactRelayzkSync Bridge
Bridge feeSnapshotRelay docs, "Cost & Fee Structure" (docs.relay.link/references/api/api_core_concepts/fees, fetched 30 September 2026): four components - Execution Cost ("$0.02 flat fee - always included" plus a destination fill-gas estimate), Swap Cost (payments to liquidity providers, DEX fees and solver rebalancing; no rate published), Platform Fees, and integrator App Fees. The Platform Fee table reads "Token Bridge & Same-Chain Wrap/Unwrap Stablecoin Swap Major Swap Minor Swap Platform Fees charged to end users 0.00% 0.01% 0.06% 0.15%", so a same-token bridge carries a 0.00% platform fee. "For regular (non-gasless) transactions, the user pays origin gas directly from their own wallet to the network".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.

How you can lose money here, and what the ranking scores
Verification failure: an invalid state or transfer is accepted.
Not assessed by this ranking: Contract failure, Control failure, Liveness failure, Custody failure, Regulatory failure, Execution failure, Exit failure. A high place says nothing about these; the Methodology tab says what each means.
Also scored, as cost, quality or a summary of several families: Route coverage (28%), Route clarity (24%), Execution speed (22%).
