Our verdict on SYNO Finance
SYNO Finance was a cross-chain lending money market built on Wormhole, spanning Ethereum, Arbitrum, Optimism, Base and Scroll. The project has shut down, and its homepage says remaining funds were returned to users, so it should not be used for new deposits or borrowing. Its main strength on paper was a single market across several networks. The main caveat is that public sources show no audits, no published fee schedule and a very small total value locked before closure. For a reader researching the project, the shutdown is the key fact. Anyone looking at similar cross-chain lending apps should check their live status, audits and fee terms first.

What is SYNO Finance?
SYNO Finance was a lending protocol described as a cross-chain money market, built on the Wormhole xChain technology stack. Listing data placed it across Ethereum, Arbitrum, Optimism, Base and Scroll, with its own SYNO token and a listing date of February 2024.
The project is no longer operating. Its homepage states that SYNO Finance has shut down and that all remaining funds have been returned to users. Users should not expect to deposit, borrow or withdraw through the protocol.
The project does not include a team, detailed documentation, a fee schedule or audit reports, so this review is limited to what the project and listing data state.
How SYNO Finance works
A lending money market pools deposits from many users into shared pools. Lenders earn interest paid by borrowers, and borrowers post collateral worth more than the amount they take out. Rates typically move with how much of each pool is borrowed.
SYNO Finance described itself as a cross-chain money market built on Wormhole's xChain technology. Wormhole is a messaging layer that lets applications on different blockchains communicate, so a single market could in principle span several networks. The project does not describe how SYNO's pools, collateral or rate settings were configured.
Because the protocol has shut down, these mechanics are background only. The homepage says remaining funds were returned to users.
Pros and cons
What we like
- It was designed as one money market spanning several networks rather than a single chain.
- It was built on Wormhole, a messaging layer with a public track record.
- The homepage says remaining funds were returned to users after the shutdown.
Watch out for
- The protocol has shut down, so new deposits and borrows are not possible.
- No audits are listed, and no audit reports are cited publicly.
- Listing data showed a total value locked of about $983 at the time it was recorded, a very small balance.
- Fees, interest rate models and collateral terms are not published publicly available.
SYNO Finance fees
SYNO Finance does not publish fee details available. Since the protocol has shut down, no current fees apply, and readers should not expect to find active fee schedules on the site.
Is SYNO Finance safe?
Public sources list zero audits for SYNO Finance and do not cite any audit reports. Lending protocols depend on smart contracts, and cross-chain designs add the risk that messages or bridged assets fail to match on each network. The Wormhole layer carries its own counterparty and smart contract risk.
The project has shut down. The homepage says remaining funds were returned, but the project does not describe the process, timing or any incidents that led to the closure. Regulatory status is not stated.
Crypto lending carries the risk of total loss. Check whether a protocol is live and audited before depositing, and check that such activity is legal where you live.
