Blueprints

Blueprints is an open-source framework for building financial products, built on the idea of decomposing financial contracts into composable code primitives so that a developer only writes the product's interface rather than rebuilding the underlying ledger and settlement logic. The framework ships with base building blocks: tokens described as ERC-20s, oracles priced by a multisig, and position types such as linear payoffs, where a position is itself a token and can nest other tokens as parameters.

The practical effect is that a newly described position can be traded in a unified liquidity venue right after it is created, without first standing up a pool or recruiting market makers. The framework encodes settlement, margin and liquidation constraints as mathematically verifiable rules that are claimed to hold in all cases. The goal is to let structured products, option-like payoffs and custom collateral arrangements ship at low engineering cost while reusing existing liquidity, instead of rebuilding a market for every new instrument.
