Somnia

Somnia is supported in Frax Mesh as a standard EVM deployment in the Fraxtal hub model. It uses the same deterministic 0x000000... OFT address set as Tempo, but it does not use Tempo's TIP-20 extensions or stablecoin-denominated gas flow. On Somnia, bridge fees are paid in native gas and routing uses the standard OFT and HopV2 contracts.

Network Constants

Required Contracts

Somnia is fully wired into the Fraxtal hub with the complete Frax OFT set plus the HopV2 relay contracts.

For the complete crosschain address matrix, including Fraxtal lockboxes and all remote Hop contracts, see Addresses.

Routing Model

• Fraxtal is the hub chain for Somnia.
• Somnia -> Fraxtal and Fraxtal -> Somnia are the direct routes.
• Somnia -> other EVM chains relays through Fraxtal with HopV2.
• Somnia uses standard OFT fee quoting and native gas. There is no Somnia-specific TIP-20 fee token path.

HopV2 Admin Configuration

The Somnia deployment in hop-v2 (opens in a new tab) includes a dedicated DeployRemoteHopV2Somnia script and a Fraxtal-side SetSomniaExecutorOptions admin script.

The required Fraxtal-side executor option is setExecutorOptions(30380, options) with a 1_000_000 receive gas budget. That is the deployed configuration used for composed Fraxtal to Somnia deliveries.

Deployment Coverage

The canonical Somnia implementation lives in these scripts:

• DeployRemoteHopV2Somnia.s.sol (opens in a new tab)
• SetSomniaExecutorOptions.s.sol (opens in a new tab)
• SetupSourceFraxOFTFraxtalHubSomnia.s.sol (opens in a new tab)
• SetupDestinationFraxOFTFraxtalHubSomnia.s.sol (opens in a new tab)
• SendFraxOFTFraxtalToSomnia.s.sol (opens in a new tab)
• SendFraxOFTSomniaToFraxtal.s.sol (opens in a new tab)

The OFT setup scripts cover all six deterministic OFTs on Somnia, and the destination setup script narrows the pairing to the required Fraxtal and Somnia configs for hub routing.

Verified Routes

The Frax team has already recorded successful send transactions in both directions:

That means the required Somnia surface area is in place: deterministic OFTs, HopV2 relay, RemoteAdmin, executor options, and tested Fraxtal hub routes.
