Automated settlement infrastructure for contract manufacturing. Escrow, verification, quality credentials. Open source.
The FairFoundry Fabric consists of a settlement engine and a quality credential system, connected by an automated verification layer.
Manages escrow, service orders, automated verification, credit ledger, and automatic payment release.
Non-transferable quality certificates issued on validated completion. Each credential is permanent, auditable proof of service delivery.
Automated inspection of factory artifacts 24/7 against acceptance criteria, triggering settlement on verified completion.
Every manufacturing service progresses through a standardized lifecycle, each stage generating its own verified record.
Five capabilities that power the settlement pipeline.
OEM deposits funds into a neutral escrow account before work begins. Funds are automatically released upon successful verification. Eliminates payment disputes and factory cash flow risk.
Fairbuild's verification layer monitors production artifacts 24/7 via direct API hooks to factory test stations. Equipment provenance — firmware hashes and bench IDs — is captured automatically to ensure data integrity.
Non-transferable quality certificates issued on validated completion. Each certificate carries permanent metadata: order ID, development stage, verifier identity, and timestamp. Certificates accumulate as a portable factory quality record.
Manufacturing partners can accumulate credits across orders instead of direct payment. Credits are redeemable on-demand, reducing cash flow friction for multi-order relationships.
48-Hour Objection Window
OEM has 48 hours after verification to raise objections. No objection means automatic settlement.
Deterministic Re-Inspection
Random sample selection that neither side controls. Rate-limited. Resolution within 96 hours.
Governance
ERS and pricing updates require multi-party approval with minimum 1-hour delay. All state changes are tamper-proof and auditable.
Automatic payment release after verification. 96 hours if OEM objects, with deterministic resolution.
Settlement engine and quality credential system. Open source, fully tested, independently auditable.
EVT, DVT, PVT, MP, and Sustaining. Each stage generates its own verified credential, building a permanent quality record.
Key public functions available on the settlement contract.
How Fairbuild integrates from first conversation to production settlement.
OEM shares ERS document. Fairbuild encodes acceptance criteria (MTF thresholds, SFR specs, cosmetic limits) as verification logic. Factory confirms test data format and upload path.
Fairbuild connects to factory's ATE logs (direct API or OEM database access). Verification logic tested against sample data. Both parties review the settlement terms encoded in the contract.
OEM creates service order and deposits escrow. Factory accepts. EVT build proceeds. On completion, factory uploads test artifacts. Verification runs automatically.
Verification passes. OEM doesn't object within 48 hours. Payment releases to factory. Quality credential issued. Total time from completion to payment: 2 days.
Each development stage creates new service orders with updated acceptance criteria. Same escrow-verify-settle cycle. Factory accumulates quality credentials across stages. OEM can engage different factories per stage.
Automated verification passes — factory's test data meets the encoded acceptance criteria.
OEM's incoming inspection shows different MTF results. They raise an objection within the 48-hour window. Escrow is frozen. Dispute resolution fee deducted from both sides.
Fairbuild engineers review both test data sets remotely. In this case: the factory's test bench was calibrated, but the OEM's reference standard had drifted. Root cause identified without a site visit.
Factory work confirmed valid. Full payment released. OEM updates their reference standard. Acceptance criteria revised for future orders to account for measurement uncertainty budget. Total dispute time: 3 days (not 3 months).
5 service orders, $150K total escrow. All verified and settled within 48 hours each. Factory A earns 5 quality credentials.
Different factory, same contract. OEM creates new service orders with DVT-specific acceptance criteria. Factory B uses different test equipment — Fairbuild reads the data regardless.
Volume production. 50+ micro-settlements per quarter. Factory C accumulates credits and redeems monthly. Quality credentials build a verifiable track record across the full program.
All three factories have auditable quality credentials. OEM compares verified completion records — not slide decks — when planning next year's program. Factory C's 50+ credentials speak louder than a reference call.
