Pick where value starts and where it lands. For each pair, this maps the real wallets and venues that connect the two chains, then characterizes which privacy properties survive the journey. Seven corridors are fully vetted (), with deeper signals; one is a preview () of a corridor whose privacy is not yet live; every other pair is provisional (): assembled from verified building blocks, but not individually hand-checked.
Vetted () corridors, marked with the green check above, are researched end-to-end: real venues with fees and timing, the exact mechanism, precise leak points, a Deeper signals read (e.g., anonymity-set size, timing correlation, liquidity and limits), and sources, re-checked as of the date shown.
Preview () marks a corridor whose privacy is not yet live (i.e., Circle Arc↔Solana today). The bridge works now for USDC, but Arc's confidential transactions are still in development, so the breakdown is projected from Circle's published design and labelled as such.
Provisional () pairs are composed from verified building blocks, as route = source × rail × destination; they are accurate as far as the blocks go, but the specific pair has not been hand-vetted.
Caveats throughout: named venues are examples and their support shifts weekly; verdicts describe the strongest honest case for each route. Verify before moving funds.
