Running a reward program or a platform?

Reward programs

Points, airdrops, referral or trading rewards: send us your program or your payout list and we run a free first check for farmed wallets, with the on-chain evidence for each one. If it helps, we check every payout list before it goes out.

What a check finds: 99% of TermiX's job fees came from wallets hiring each other.

Launchpads, wallets and trading bots

Warn your users before they buy. A free first check of your last week of launches: which launch wallets dumped, and which launch dozens of tokens a day. If it helps, get it as a daily feed or through our API.

See it on one token: the free rug check.

How to read a report

Every report opens with one answer: Pay or Hold. If there isn't enough recent history to judge, it says so (Inactive or No track record) instead of guessing. Below the answer: the reason, and what we checked to get there.

Pay means nothing turned up
Pay means we found nothing on-chain against paying in the last 30 days (14 on BNB Chain). It isn't a guarantee, so for a big payment, start small.
Hold means look closer
Hold means something should make you stop, like USDC left sitting in a wallet that has gone quiet. The report names it.
Check it yourself
Every finding links to the on-chain record, so you can see the transactions behind it.
Free and public
Every check on the site is free. The first check of an address files a public report you can share.
What we cannot see
Promises made off-chain, private deals, or what someone intends. We only read what the chain shows.

On the record
  • DefiLlama counts Bankr's fees with the on-chain adapter we wrote.
  • SmartFlow Observatory cited our count of x402 settlements on Base in Weekly #15.
  • PayAPI Market verified our paid check with a settled payment.
  • x402scan lists every payment our checks have taken.

ChainWard reads Base directly and tells you what the chain shows: the answer, the reason, and the evidence. On-chain behavior only, so it can't see promises made off-chain. Free and public.
