DeFi Money Legos

DeFi Money Legos is a metaphor for the open-source, permissionless nature of decentralized finance protocols that allows them to be combined like modular building blocks. Because most DeFi protocols are built on the same blockchain and use standard token interfaces, developers can easily integrate external protocols into their own.

This allows for the rapid creation of complex financial products by layering existing services. A user can create a position that borrows assets, swaps them, and deposits them into a yield farm, all in a single transaction.

This modularity accelerates innovation but increases the technical complexity of the overall system. It is the fundamental architectural principle behind the rapid growth of the decentralized finance sector.
