Will it slow my pages down?

No. A request takes about 200ms and the SDK fails open. If a request errors or finds no match, your page renders as it would without us.

What creative formats do I need to support?

Three standard formats, rendered with a normal image tag (creatives may be GIFs): landscape 16:9 (640×360) for hero and featured slots, long banner 8.09:1 (1456×180) for headers and leaderboards, and short banner 16:5 (640×200) for inline, sidebar, and mobile slots. Each SDK call requests one format and returns at most one ad.

Does this conflict with my existing ad stack?

No. Specify sits above your stack at first-look priority. We fill when a visitor matches a campaign and return no-fill otherwise, and your existing network proceeds. No exclusivity, no minimum volume.

Do my users need to connect a wallet on my site?

No. If they do, pass the address through the SDK for the most matches. If they do not, Specify ID recognizes visitors who connected a wallet on another site in the network.

When and how do I get paid?

Monthly. A payment slip arrives by email and in your dashboard at the end of each period, and we pay within 30 days by bank transfer or crypto.

Can I control which ads appear?

Yes. Allow lists, block lists, and category controls are in the dashboard. We never serve filler, so an empty slot is the worst case.

Quality

Relevant to what your users already do.

We show an ad only when the wallet’s history matches the advertiser. Coin98 runs our placements as a recommendations card.

When nothing matches, we return no ad.

Trust & privacy

For your privacy review.

Consent first

The SDK sets the identifier only after consent. Without it, we fall back to plain wallet matching.

Wallet-anchored identities

Each identity starts with a wallet the user connected themselves. We add only public onchain data.

What leaves the page

The ad request and, with consent, the Specify identifier. We do not read page content or browsing history, and we do not fingerprint.

Measured onchain

We count conversions from onchain data, so no tracking script runs on your pages.

Brand controls

Allow lists, block lists, and category controls, all in the dashboard.

GDPR documentation

Ask and we send the full pack.
