PRIVACY FIRST · ONE REAL OWNER · SOURCE AVAILABLE
Original open-source tools for developers handling difficult CSV exports, Base USDC payments, and x402 payment challenges. Start with verifiable free examples; optional paid reports require a separate agreement.
무료 브라우저 CSV 검사와 x402 결제 견적 확인을 제공하고, 별도 합의 시에만 유료 기술 리포트를 작성합니다. 지갑 서명은 견적 조회에 필요하지 않습니다.
ACTUAL ORIGINAL PROJECT TOOLS
For an unsupported export, explicitly map its real source columns into documented Simple, Trades or Universal Koinly headings. Your file stays in the browser, rows and values are retained. An independent structure checker helps flag formatting issues; a pass is not proof of Koinly acceptance or tax correctness.
Free local Koinly header mapper ↗ · Optional 5 native Circle Base USDC / 10-row HashN manual mini-review (buyer-initiated) ↗ · Separate free structure check ↗Inspect fictional duplicate export records, missing acquisition references and unmatched transfer sides. Not tax advice; no cost basis invented.
Free fictional CSV demonstration ↗Review input-only Base Circle USDC transaction-to-invoice candidates. Similar amounts do not establish payment, wallet ownership or onchain finality.
Free invoice exception demonstration ↗View an unsigned quote's real network, token, price and recipient. A 402 response alone does not mean a customer paid.
Inspect the public challenge ↗The free price check sends only fictional rows. A separate user-approved paid request can transmit their own non-sensitive CSV after signing.
Check price without payment ↗INDEPENDENT MERGED SOURCE CONTRIBUTION + REAL NANO MAINNET PAYOUT
The original developer fixed a real wallet-lock reaper race in pursekeeper/api PR #94. The independent sponsor merged the tested code and sent 5 XNO on Nano mainnet, with a public payment block and ledger entry 441. At the original public verification, the send was confirmed but the recipient still had 5 XNO receivable / 0 XNO spendable. This is one completed paid bounty, not a new USDC customer, tax advice, or a cash withdrawal.
ACCURATE COMMERCIAL BOUNDARIES
AI-assisted source is developed for one human economic owner. VM1, VM2, VM3 and VM5 are development environments, not customers or external endorsements. We do not claim unverified paid purchases, financial expertise or professional accounting, tax, legal or security certifications.
A smaller, optional original HashN 5 native Circle Base USDC / maximum 10-row Koinly mapping mini-review is separately available only after a buyer voluntarily contacts the original seller and both agree on written scope, legal data rights, safe delivery, cancellation/refunds and native Base payment. HashN listing publication is not proof of escrow, paid client or Koinly acceptance.
A proposed $49 USD private CSV source review or USDC invoice exception report is not an automatic purchase. A real customer must agree scope, deliverables, privacy, lawful payer/payee, refund and acceptance terms before sharing any sensitive information or spending money. Never post private wallet keys, tax data, invoices or customer credentials to a public form.
Email links create a draft in your own email app; nothing is transmitted until you choose Send. The separate consent-based form may require an anti-spam check. The proposed US$49 manual pilot is not a fixed checkout, guarantee, order, customer testimonial or tax service.
