SANDBOX DEMONSTRATION · UPDATED 12 NOVEMBER 2026

A clear agreement for this demonstration.

Fieldproof is a work-in-progress sandbox demonstration. All PayPal activity uses test funds. The fictional Eastside project is not a live fundraiser, school affiliation, charity, or tax-deductible giving program.

What the labels mean

Sample records illustrate a workflow. Live sandbox records come from an actual provider interaction using test funds. A pledge is not a payment, an invoice is not proof of settlement, and a payment is not proof of physical work. Human review is required for claims, evidence, repayment approval, and publication.

Sandbox contributions

The connection test requests a $1.00 sandbox contribution. A purpose contribution shows its exact amount, named purpose and original terms before you choose to approve it in PayPal. A pledge, sponsor agreement or project invitation is not a payment approval. Approving one checkout does not approve future charges. Use only your own authorized sandbox account. Current session, purpose and application limits are checked by the server.

Conditional collection policy

The planned conditional pledge policy asks a supporter to pay only after the relevant package reaches its stated commitment target before its deadline. Collection starts a fixed 48-hour recovery window. An uncertain original payment must be reconciled before an alternative collection route opens. Incomplete collection must not be spent. An extension requires renewed consent.

Saved-wallet collection, recovery invoices and reviewed Payouts have their own runtime qualification gates. The current sample commitment does not charge a saved wallet. UI status must describe what has actually been observed.

Responsible use

Use your own authorized sandbox accounts. Do not upload confidential documents or use this demonstration to make real financial decisions. Fieldproof does not certify building safety, completed construction, charitable status, or legal compliance. Any actual physical signoff needs a qualified reviewer.
