Summary

Adds direct Morpho Blue lending-market support for the USDC ARM.

  • Adds an ERC-4626-compatible MorphoBlueMarket wrapper around a single Morpho Blue market.
  • Uses one shared implementation with a separately configured proxy for each market.
  • Projects pending interest and protocol-fee dilution when valuing Morpho supply shares.
  • Limits withdrawals and redemptions based on available market liquidity.
  • Restricts position movement to the linked ARM.
  • Supports token-agnostic reward collection:
    • USDC rewards return to the ARM.
    • Other reward tokens are sent to the harvester.

Deployment

Adds deployment 043, which deploys and registers wrappers for:

Market Market ID
OETH/USDC 86% 0xb8fef900b383db2dbbf4458c7f46acf5b140f26d603a6d1829963f241b82510e
WBTC/USDC 86% 0x3a85e619751152991742810df6ec69ce473daef99e28a64ab2340d7b7ccfee49
cbBTC/USDC 86% 0xba3ba077d9c838696b76e29a394ae9f0d1517a372e30fd9a0fc19c516fb4c5a7
cbBTC/USDC 86% 0x64d65c9a2d91c36d56fbc42d69e979335320169b3df63bf92789e2c8883fcc64

The deployment:

  • Verifies each configured parameter set against its expected Morpho market ID.
  • Uses the 5/8 multisig as wrapper owner.
  • Uses the buyback operator as harvester.
  • Registers all four wrappers with the USDC ARM.
  • Does not activate a market automatically, allowing the operator to select one later.

Testing

Adds unit coverage for:

  • Proxy initialization and market configuration.
  • Multiple proxies sharing one implementation.
  • Deposits and complete position redemption.
  • Pending interest and protocol-fee accounting.
  • Liquidity-constrained withdrawals and redemptions.
  • ARM-only position movement.
  • Token-agnostic reward routing.
  • Harvester authorization.
  • Rejection of unknown Morpho markets.
