SiliconRelay is a real-time advertising exchange connecting advertisers with independent publishers through direct, first-price auctions. The platform emphasizes transparency, publishing a flat 20% take rate and using a shared event log so both sides can verify how traffic is counted, filtered, and billed. Advertisers can run direct-served campaigns across independent websites, fund accounts in USDC, and set daily, weekly, or monthly budget caps.

Reconciliation is based on the same event log used for billing, helping advertisers track campaign activity and spending. Publishers can add a single tag to their sites to access direct demand and retain the remainder of each dollar after the published fee. SiliconRelay also provides plain-language receipts for traffic that does not qualify for payment.

Publisher earnings are paid monthly in USDC once balances meet the applicable threshold, with payouts sent on the fifth. The service includes help resources for campaign setup, creatives, funding, publisher zones, tag installation, and payments, as well as a public traffic-counting policy and security vulnerability disclosure information
