Ulysses Review: Is This Cross-Chain Protocol Worth Using?
Ulysses is described as a cross-chain liquidity and swap protocol, but its app is branded Hermes and publishes little about fees or safeguards. Treat it as a cautious, verify-each-transaction option rather than a proven bridge.
By the SkyBitcoins review team · Updated
Quick take
Ulysses may suit experienced DeFi users looking for cross-chain swaps or liquidity, but the app is branded Hermes and its public details are sparse. The main reason to consider it is its stated focus on omnichain liquidity across a broad set of networks. Before depositing, confirm the app, route, fees, destination and contract details; two listed audits are not enough without their reports and scope.

What can you do with Ulysses across chains?
Ulysses is described as an omnichain liquidity protocol intended to support cross-chain swaps and liquidity deployment. In practical terms, a bridge or cross-chain swap can let you move an asset from one network to another without handling every step manually. The app’s own title and description use the name Hermes Protocol, however, so the connection between Ulysses and Hermes is not clearly presented. Confirm you are using the intended product before connecting a wallet.
The listed networks are Ethereum, Metis, Optimism, BNB Chain, Base, Avalanche, Sonic, Arbitrum, Berachain, Fraxtal, Swellchain and Polygon. That list does not guarantee every token or route is available at any given time. Check the exact source asset, destination asset and receiving address in the app. The available information does not establish the protocol’s current route coverage, liquidity depth or transfer times, so avoid assuming a route will complete simply because both chains appear on the list.
How much could a Ulysses swap cost?
Ulysses does not publish a clear fee schedule in the available project details. Before confirming a swap or transfer, inspect the quote for any protocol charge, exchange rate, slippage allowance and minimum received amount. Cross-chain transactions can also involve network gas, including gas on the source chain and, depending on how the route works, costs or fees on the destination side. These are separate from any protocol fee.
Do not judge a route by its headline exchange rate alone. Compare the amount you will actually receive with the amount sent, and check whether the displayed quote can change before execution. If the app does not show the full cost or the destination amount in a way you understand, stop rather than approving. Liquidity-pool returns, if offered, should also be checked for pool fees and any incentives or conditions; no current reward rate or pool terms are established here. Because costs and route availability can change, verify them in the app immediately before each transaction.
What do the audits tell you about Ulysses?
Two audits are listed for Ulysses, but the audit firms, dates, reports and covered contracts are not specified. An audit is useful only when you can confirm which version and components it assessed, and it does not guarantee that a protocol is free of bugs or that funds can always be recovered. Look for the actual reports and check whether they match the contracts you are about to use.
The available details do not establish whether Ulysses is non-custodial, how it handles failed or delayed transfers, or what security monitoring and incident history it has. Do not treat the term “permissionless” as proof of safety. Verify contract addresses through the project’s official channels, read wallet prompts carefully and begin with an amount you can afford to lose. If a transaction asks for an unexpected token approval or permissions broader than the swap requires, reject it until you understand why.
What should you check before using the Hermes app?
The app is presented as Hermes Protocol, while Ulysses is described as the cross-chain liquidity protocol. That naming difference makes it especially important to verify that the interface you opened is the intended app before connecting a wallet. The project lists twelve networks, but the current wallet support, mobile experience, route speed and transaction-status tools are not specified.
A cross-chain transfer usually requires you to select a source network and token, choose a destination network and asset, then review a quote and approve the required transaction in your wallet. The exact steps and approvals can differ by route. Check that your wallet is on the correct source chain, that you have enough native gas, and that the destination address and received asset are right. Keep your transaction hash and do not repeat a transfer just because a cross-chain message takes longer than expected. Check the app’s route and status information first; transfer times are not published.
Who should use Ulysses—and who should look elsewhere?
Ulysses may be worth investigating if you already understand wallet approvals, bridges and the risks of cross-chain transactions. Its stated purpose is relevant to users who want to swap or deploy liquidity across networks, and its chain list is broad. But the project does not publish enough detail to compare its fees, execution quality, custody arrangements or recovery process confidently.
Pick another bridge if you need a published fee schedule, independently verifiable audit reports, clear support and refund procedures, or a well-documented custody model before you move funds. Liquidity providers should verify current pool depth, terms and any rewards directly; none are established by the details here. A broad chain list is not a substitute for checking liquidity on the specific route you need. Until the app makes the key costs and safeguards easy to verify, treat Ulysses as a higher-caution option and avoid transferring an amount that would create a serious loss if the route failed.

How to start with Ulysses
