Bonus abusers look like ten new players. Sameveil looks at what they share — device, card, mailbox, network, timing — and hands your team the links and the reasons, in a few milliseconds, at signup, bonus claim and withdrawal.
Advisory, never blocking. Hashes in, decisions out. Runs in our cloud or inside your network.
What you get
"Same device as six other accounts. Email is a plus-tag variant of one you already have." Sentences your analysts can act on and your regulator can read — not a probability.
Signup is where it starts, not where it ends. Sameveil scores the bonus claim and the withdrawal too, because the payout card is where a ring finally shows its hand.
Confirm one account as fraud and every account linked to it scores higher from then on. One click, the rest of the ring surfaces. No model to train.
Integration
It computes a device fingerprint in the browser and puts it in a hidden field. No cookies, no third-party calls, 150 readable lines.
Your backend sends POST /v1/score with hashed email, phone and card, plus IP, device and country. We never see raw PII.
allow, review, block_bonus or block, with reasons and linked accounts. Timeout 200 ms, fail open. We advise, you decide.
Send three months of hashed history. We send back a report: linked clusters, bonuses paid to them, and which ones nobody closed. Free, under NDA, no commitment.
