Sellers vet402 paid on Solana, Tempo and Base

Are you a seller listed here?

• Your page (click your name) shows every purchase vet402 made from you, with its tx, and which failures count against you and which do not.
• A seller who thinks a row is wrong opens a GitHub issue with the URL or tx. vet402 checks it against the chain and the raw result; a wrong row is fixed and the fix is noted in the change log. How corrections work
• Signed records of failed purchases, and the Robinhood Chain and Arbitrum results, are published only after the seller is told. The tables here count every purchase as it happened.
• It costs the seller nothing, and there is nothing to sign up for.

Came back with an answer = vet402's payment settled, then the seller answered 2xx with a non-empty body. vet402 did not check that the answer is what the listing promised; whether its keys matched what the seller declared is a separate column.

Solana: 1944 tried, 1835 settled, 1776 came back. Tempo: 380 tried, 377 settled, 281 came back (for 73 of these 380 the runner kept no body, so for them "came back" means settled, then 2xx; the other 307 were tested for an empty body). Base: 8 tried, 7 settled, 7 came back.

A grade needs 10 counted purchases on 2 different days; 111 sellers on this page have one. Rebuy plan from UTC day 2026-09-29, with no end date: two runs a day on Solana and one on Tempo, each buying again from the Solana and Tempo sellers whose earlier payment settled, to the same payTo and at no more than the earlier price. Spending is capped per calendar month (70 USDC on Solana, 30 USDC.e on Tempo); a chain that reaches its cap buys nothing more until the next month. The ledger allows one purchase per recipient per slot per UTC day, so where several sellers share one payTo, one of them is bought. Which sellers were bought again is decided by the rows in data/remeasure/, and a correction can change them. Through 2026-10-09, the data holds 2045 purchases bought again from 132 sellers on 11 UTC days (Solana 1739, Tempo 306).

Undecided (1): enough purchases, but the interval is too wide for a grade

A grade is not the verdict on the Check page. A grade (A to D) orders sellers and needs 10 counted purchases on 2 days; the verdict (pay, avoid, unknown) answers one question before paying, and can be given from 4 counted purchases on 2 days. What the verdict means

Jump to: Solana (141) · Tempo (73) · Base (8)

Solana: 141 sellers

Tempo: 73 sellers

Base: 8 sellers

payTo changed for 2 sellers between runs or at payment. Shown on their pages; no effect on the grade.

How vet402 pays for this

Grades come only from vet402's own purchases. vet402 also sells paid checks (paid in USDC on Algorand or Base); a paid check is a separate report and never moves a grade. Every purchase file the grades read is in data/ with its sha256.
