Audit-ready guide to modular DeFi lending: Morpho Blue singletons, Euler V2 vault kits, EIP-4626 standards, oracle risk, and MiCA compliance for July 2026.
Frequently Asked Questions
- Modular lending isolates risk into pair-based markets, specifically Singleton and Vault Kit architectures, preventing a single asset failure from draining the entire protocol's liquidity.
- The July 1 deadline ends the MiCA transitional period, requiring protocols with identifiable centralized touchpoints to be fully authorized under EU law. The Travel Rule applies to all VASP-to-VASP transfers with no de minimis threshold.
- ERC-7201 isolates storage slots across delegation boundaries, preventing storage collisions in protocols implementing EIP-7702 or ERC-4337 accounts. Without it, mandated security upgrades can cause permanent capital loss through slot overwrite.
