Composability
technology · defi
The ability of applications and protocols to combine compatible interfaces and state into larger workflows.
Composability lets one application call, route through, or interpret another system's contracts and data. Some interfaces are permissionless, while others depend on allowlists, governance, upgrade keys, proprietary APIs, or off-chain operators.
Composition can reduce duplicated work and create useful workflows, but it also imports dependencies. An oracle failure, contract upgrade, liquidity shortage, or governance action in one component can cascade into every product built on it.
