Proof
Read the engine's page: what Vlaander measured and on which hardware, what it has not measured, and the open review findings. Nothing runs before purchase.
Verified businesses only. Place the order, give your company's details, have your authorised signatory sign the Sale and Assignment Agreement, then pay the invoice in naira by bank transfer, or in USDC on Polygon. Once the payment is verified, your account shows Paid.
We confirm the funds and release the source tarball to you. Delivering, then Download ready. Check it against the SHA-256 in Schedule 1, then rerun the tests and benchmarks yourself.
Each figure is labelled as measured by Vlaander or stated in the catalogue. Measured figures come with the date, hardware, compiler and source archive fingerprint, and the benchmark tools ship with the source so you can rerun them after delivery. Stated figures are not promised.
Every asset has been through Vlaander's own review. Open findings, untested paths and gaps are listed on its page, next to what is fixed in the source you receive.
Nothing runs before purchase. The source is released only after your authorised signatory has signed the Sale and Assignment Agreement and your payment is confirmed, through a link that expires. Releases are not signed: check the source tarball against the SHA-256 in Schedule 1 of your agreement. No refund is available after delivery, except where a remedy cannot lawfully be excluded.
