Private financial workflows, proven.
Weld is a shielded payment pool where every regulated party proves that its private policy permits each transition, and a Noir framework that makes writing such a policy feel like writing a React component. The protocol is shaped so the framework has almost nothing dangerous to do.
Judge typed, already-anchored values. Return a verdict. The framework owns the lifecycle, the anchoring, the witness plumbing, packaging, registration, and testing.
Initiate spends inputs into a hold. Accept and reject publish identical records, so the chain learns that a hold closed and never how.
Records with signatories and observers, choices with controllers, and fragments joined by one proof. Sub-transaction privacy enforced cryptographically.
Every value a rule judges is welded to a public root. The build fails on a policy that cannot prove on a golden payment shape.
