This strategy lets users perform minting using Reservoir rUSD and take it a step further by depositing to a Morpho position on Katana. Route Mechanics: This bundle facilitates stablecoin diversification across chains through a the following process:
  • Convert USDC to wsrUSD_ETH on Ethereum using Enso’s routing
  • Bridge the newly minted rUSD from Ethereum to Katana chain via Stargate
  • Check wsrUSD balance on Katana after bridge completion
  • Deposit wsrUSD to wsrUSD/vbUSD Morpho position
The strategy enables users to access Katana’s DeFi ecosystem while starting with familiar USDC on Ethereum and relying on Reservoir Stablecoin.

Important Considerations
  • Bridge operations execute sequentially - Katana operations only proceed after successful Ethereum minting
  • LayerZero bridge fees apply for transfers between Ethereum and Katana
  • Gas costs for both chains are paid from the originating Ethereum transaction
