16 / Builder challenge

Build one integration another developer can verify.

The PactVerity Integration Challenge is accepting proposals for three independent reference integrations. Selection, implementation and acceptance are separate evidence gates.

ApplicationsOpenReference awards3 × 1,000 USDCPool statusCommitted, not escrowed
Funding boundary:PactVerity has committed a 3,000 USDC maximum reward pool, subject to eligibility and written award terms. Funds are not yet publicly escrowed. No applicant should begin paid work until selected in writing.

01 / Challenge

Three useful integration tracks.

Each entry must use a real public or test service, call the operational Receipt API beta and disclose where its evidence originates.

Public questions and independent review

Use the GitHub work items for scope questions that benefit every applicant. Qualified security reviewers can also respond to the separate independent review request . Do not post secrets, private customer data or vulnerability details in a public issue.

02 / Required deliverables

Acceptance requires working public evidence.

  • A public source repository with an open-source licence and setup instructions.
  • A working integration that calls the PactVerity Receipt API beta; a mock-up alone does not qualify.
  • A recorded demonstration and a machine-readable sample assurance receipt.
  • A reproducibility guide with test inputs, expected outputs and known limitations.
  • No secrets, customer data, misleading adoption claims or token-price promotion.
  • Disclosure of employment, investment, sponsorship or other material connection to PactVerity.

03 / Public judging

A 100-point evidence rubric.

Submissions must score at least 70 overall and cannot pass with a zero in technical correctness, reproducibility or security.

CriterionPointsWhat is evaluated
Technical correctness30Real API use, valid receipt construction and accurate status boundaries.
Reproducibility25A second developer can run the project and obtain the documented result.
Evidence quality20Measurements are relevant, traceable and not presented as independently true when caller-supplied.
Security and privacy15No exposed secrets, unsafe wallet requests or unnecessary personal data.
Clarity10Concise documentation, useful demo and explicit limitations.

Reward terms

Three accepted reference integrations may each earn 1,000 USDC. Payment becomes due only after the public repository, working demo, sample receipt and limitations pass the rubric and are accepted in writing. Payment is targeted within seven days of acceptance, subject to lawful eligibility and receipt details. No PVTY purchase, holding or promotion is required.

04 / Apply

Propose a reference integration.

Applications are reviewed for fit before implementation. An application is not acceptance, endorsement, employment or a promise of payment.
