This annex provides additional information about Third Party service providers integrated with VaultBridge and the Katana ecosystem, as referenced in the main Terms and Conditions.

Third Parties provide integrated functionality within the VaultBridge and Katana ecosystem, including:

Third-Party Vaults

Vaults are on-chain smart contract systems that receive bridged assets from the Protocol and deploy them into predefined yield strategies. When a user bridges assets, the Protocol deposits them into vaults on Ethereum to generate yield, which accrues to vbToken holders on the destination network. These vaults are operated by independent protocol teams, and neither Polygon Labs nor Katana control the vault strategies. Assets remain in the third-party vault smart contracts.

Morpho

VaultBridge deposits are routed into smart contract vaults deployed by the Morpho protocol. These vaults implement yield strategies on Ethereum and are subject to Morpho's smart contract parameters, governance, and associated risks. Deposits made into Morpho vaults are non-custodial and governed by the Morpho terms of service and risk disclosures. Further information is available at: www.morpho.org/vaults/ and docs.morpho.org/overview/resources/risks.

Curators

Steakhouse Financial

Steakhouse Financial serves as a curator for vaults accessible via VaultBridge. It contributes to vault design, risk modeling, asset selection, and strategy optimization. Steakhouse does not custody user funds and does not guarantee yield outcomes.

Gauntlet

Gauntlet acts as a curator for vaults accessible via VaultBridge. It contributes to vault design, monitoring, and optimizing risk-adjusted yield strategies, allocating capital across markets and managing risk parameters on behalf of users. Gauntlet does not custody user funds and does not guarantee yield outcomes. Gauntlet's Terms of Service can be reached at https://www.gauntlet.xyz/tos

Vault Provider

In some cases, Katana Interface may integrate with third party vaults, hosted and managed by third party vault providers and curators. Yearn is one example of that.

Bridging Aggregators

Trails

Trails powers Katana's cross-chain bridge, swap, and deposit flows so users can fund opportunities or enter vaults from any EVM chain, wallet, or token in 1-click. Trails handles intent orchestration, routing, and settlement behind the scenes.
