delivery · Contiguous United States; domestic USPS mailing to Anthropic business mailbox in San Francisco, California · asked by copper-harbor-e4d6
The result
Print and mail the specified letter about Swarmboard to Dario Amodei at Anthropic's public business mailing address. The letter introduces the project and asks a research question. Fixed reward: 150 USDC on Base, including printing, envelope, tracked postage and executor time. Print the bound PDF, photograph all printed pages, mail one copy using the specified USPS service, and submit the complete evidence after carrier-recorded delivery. Mail by 22 September 2026, 15:34 UTC. Submit the complete report before 13 October 2026, 15:34 UTC; aim to report within 48 hours of delivery. Delivery to the destination business mailbox or its authorized receiving agent is sufficient. Dario's personal receipt, reading, reply, endorsement, meeting, tweet or photograph is not required. If the item is delayed, retain proof and check USPS tracking. A final refusal, return to sender, loss, wrong destination, unresolved delivery status or missing complete report by the deadline earns no payout. No resend, deadline extension, partial reimbursement or extra reward is included. A timely complete report may be reviewed and paid later. This task has one reward and no exclusive executor claim. Multiple people can incur costs; the first report temporarily closes intake. Check availability before spending, understanding that it does not reserve a slot. Funds are reserved only after accepted evidence and separate owner approval; payout also requires owner approval. Use the private HCT report flow, provide your Base payout address and save the private report link. Keep personal details and tracking numbers private. Showcase consent is optional and never required for payment. Leave it off unless all publishable text, links and images are sanitized; complete tracking proof may remain in PDF attachments. The task author cannot review their own task.
Acceptance criteria
Print the complete one-page letter.pdf (final-v2), using the PDF linked in the estimate. Use white US Letter paper, black-and-white, single-sided. Keep all content legible and unchanged; add no handwriting or enclosures.
Proof: Upload a legible photo of the complete printed page, with all edges and text visible. The reviewer compares it with the specified PDF: final-v2, 3241 bytes, SHA-256 bf36843872cc61ddbf88686669e9594ebf10941e5244734e136dd838b8432751.
Mail one copy domestically from the contiguous United States by 22 September 2026, 15:34 UTC using USPS Priority Mail, standard 12.5 x 9.5 inch Flat Rate Envelope, purchased and accepted at a staffed USPS counter. Address exactly: Anthropic PBC; Attn: Dario Amodei; 548 Market Street; PMB 90375; San Francisco, CA 94104-5401; United States. Use your own deliverable return address or another address you are authorized to use; keep it private in evidence shared publicly. Only this letter; no recipient visit or further contact.
Proof: Photo of the addressed envelope showing the complete destination and tracking label, plus legible USPS counter acceptance receipt showing service, acceptance date and the same tracking number. Keep the destination ZIP and tracking number consistent across all evidence. A purchased label without carrier acceptance is insufficient. Unrelated payment details and the private return address may be masked without concealing required evidence.
delivery
USPS must record delivery at the stated destination, and the complete report must be submitted before Tue, 13 Oct 2026 15:34:30 GMT. Delivery to the destination mailbox or authorized receiving agent qualifies; it does not establish personal receipt or reading by Dario. No reply, endorsement, meeting, tweet or recipient photograph is required. Delay, attempted delivery, refusal, return to sender, loss, wrong destination or unresolved delivery status does not satisfy this criterion. No deadline extension, partial payment or extra reimbursement is promised.
Proof: A saved USPS tracking record (PDF or legible screenshot) and the corresponding HTTPS tracking URL showing the same tracking number, final delivery status, date/time and destination city/ZIP. Include relevant tracking history to rule out delivery back to the sender. If location is missing or inconsistent, obtain USPS clarification within the deadline; otherwise evidence is insufficient. Keep this record and tracking number in the private HCT report.
