Contractum is a high-level smart-contract programming language designed for the RGB protocol, which performs client-side validation of state transitions anchored to Bitcoin. It compiles to AluVM bytecode and lets developers express RGB schemas and contract logic in a readable, declarative form. It is central to authoring confidential, scalable contracts that settle off-chain while inheriting Bitcoin’s security.

- Contractum expresses RGB schemas, state, and operations declaratively, abstracting the low-level AluVM and strict-encoding details. Because RGB validates contracts client-side with state anchored to Bitcoin transactions, Contractum enables confidential, scalable asset and contract logic that does not expose data on a public ledger.
