Compose

Compose is a development framework that brings off-chain computation results on chain. Developers write orchestration logic in TypeScript that runs inside a trusted execution environment, then submit the output together with an execution proof to on-chain contracts. It serves decentralised applications that need external data or multi-step flows.

It addresses the limitation that traditional oracles only relay simple values and cannot carry multi-step external calls or conditional logic. Mechanically it packages off-chain execution into reusable orchestration units, a trusted execution environment produces the execution proof, and the contract only verifies the result without trusting the off-chain executor. A published example covers settlement triggers for Polymarket's 15 minute markets. It belongs to the narrative of off-chain computation and oracle infrastructure.
