Plan a useful feed

Decide what your feed should price and which application could use it.

For example: “My application needs a reference for this token,” or “I want one price for this specific combination of assets.”

Choose the definition

1. Identify the asset. Use its Solana mint, not just a name or ticker.
2. Choose the quote. Is the price expressed in USDC, SOL, or another supported quote?
3. Check the sources. The relevant pools must be supported and admitted, with suitable liquidity.
4. For a composite, choose quantities and conversions. Components can start in different quotes. Include the conversion feeds Mimir needs to express them in the composite's quote, such as SOL/USDC for an input priced in SOL.

For a composite, write down the exact tokens, quantities and quote. A name such as “AI Chips” describes the idea; the composition defines the price.

Give it a unique ticker

Your feed gets a short, unique ticker so people can recognize it quickly in the Mimir terminal. For a feed named AI Chips, you might choose CHIPS, if it is available.

Choose 2 to 6 letters or digits. Letters are converted to uppercase, and Source and Composite Feeds share the same ticker namespace. A ticker already assigned to another feed cannot be reused within the same Mimir deployment.

The ticker identifies your feed, not a token. It does not have to match an underlying asset's symbol, and it does not replace the mint addresses or composition that define the feed.

Plan how it stays useful

Which application needs this reference? It can refresh the feed and consume the result in the same transaction, without relying on a keeper to update it continuously. Plan who covers the applicable SOL fees and what source quality the application requires.

Applications select feeds according to their source coverage, liquidity, freshness and risk policy. Designing for a clear use case helps your feed meet those needs.

Understand the costs

Feed creation uses $COLA, which is permanently burned. Paid updates use SOL. Solana transaction fees and the SOL needed to create accounts are separate costs. Review the amounts before signing.

Feed activity and fees depend on how applications and other feeds use it. Read fees and claims →

Before you confirm

Check the mint, quote, sources and component quantities carefully. Finalized source bindings are immutable; a different definition requires a new feed.
