Synapse scores 8.2 out of 10 and ranks #6 of 8 in the best cross-chain bridges table, strongest on coverage (8.8) and weakest on trust assumptions (7.8).
Broad coverage including smaller chains that better-secured bridges skip, using a liquidity-pool model with an optimistic verification layer. Useful reach, average trust assumptions.

Covers many smaller chains that canonical routes do not reach.
Synapse covers many smaller chains that better-secured bridges skip, which is a real service: an asset stranded on a network nobody bridges to is an asset you cannot use. Transfers are backed by liquidity pools with an optimistic verification layer, and no major protocol exploit appears on its record.
Its validator and verification setup is less robust than the leaders in this table, and its permissioned validator set is the trust assumption to weigh. On the routes where Across or Hop reach, they are the better choice; Synapse earns its place on the routes where they do not.
Delivery is fast and fees are published per route, with costs rising on thin routes where pool liquidity is shallow. Check the quote for the specific route rather than assuming a headline fee applies everywhere.
Users with assets on smaller networks, moving amounts sized to the pool depth on that route rather than to the protocol's total liquidity.
On routes served by Across, Hop or CCIP, those are better-secured choices. Synapse's value is coverage — it reaches networks the others have not deployed to, and that is worth having when the alternative is stranded assets.
No major protocol exploit appears on its record, and transfers are backed by liquidity pools with an optimistic verification layer. Its verification model is weaker than the leading bridges', and its validator set is permissioned.
When the route you need is not served by better-secured bridges — its coverage of smaller chains is the reason it exists.
Because pricing depends on pool depth for the specific route. Thin routes cost more, so check the quote for your pair rather than a headline rate.
