Composable money is like financial building blocks

Composability is presented as a major value of open, permissionless money systems, letting financial products be built like modular Lego bricks rather than rigid, siloed services. The article says composability lowers the cost and capital needed to launch financial products, and it cites token standards ERC-20 and ERC-721 on Ethereum as building codes that expand what can be built. It also gives examples including yield farming and liquid staking, tokenization of real-world assets such as real estate and fine art, decentralized exchanges, interoperable NFTs, and DAOs.
