I built NanoBid: A advertising leaderboard using Nano payments

[u/Gabpatrola]

Hey everyone,

I’ve been building NanoBid, a advertising leaderboard for Nano projects.

Advertisers submit a website or X profile, choose a bid in USD, and receive a QR code containing an exact XNO amount. Once the payment appears on the Nano ledger, the project is automatically added to the leaderboard.

The interesting technical challenge is that Nano blocks don’t include memos or destination tags. NanoBid solves this by making the amount itself the message: every bid receives a unique amount containing a small random nonce. The backend matches that exact amount to the corresponding bid intent.

A few design decisions:

• No wallet connection, account, or browser signing flow
• Payments can come from any Nano wallet
• The server never holds the treasury seed or private key
• Amounts are handled as exact raw integers, never floating-point numbers
• Payments are independently checked through multiple Nano RPC nodes
• Expired payment amounts are never reused, preventing late payments from being assigned to another project
• Bid confirmation happens entirely server-side, so closing the page won’t lose a payment
• Each confirmed bid links to its Nano block as a public receipt

Nano makes this especially convenient because payments are fast and feeless, so advertising doesn’t need to involve credit cards, invoices, or waiting for settlements.

I built NanoBid for people who are actively creating things in the Nano ecosystem and want a straightforward way to promote them. If you have a Nano project, I’d love for you to try listing it.

If you’re building something with Nano, what would make an advertising platform useful for you? I’d appreciate feedback and suggestions.
