Set token display interest rate on Solana
Change the display interest rate of an eligible Solana Token-2022 token. This changes its displayed amount calculation, not its raw token balance.
Service fee: 0 SOL
Token controls
Actions depend on this token’s current permissions. Removed authorities cannot be restored.
Project page & links
Publish a public project page or update its links. Approve edits with the project owner’s wallet message. This does not change on-chain metadata.
Contract source
Before you start
A Token-2022 mint created with the interest-bearing extension and its rate-authority wallet.
How to use this tool
- Inspect the current display-rate configuration.
- Enter the supported display interest rate in percent.
- Review and approve the new rate with its controlling wallet.
What changes
The extension changes how token amounts are displayed over time. It does not mint rewards, increase raw balances or promise yield.
A changed display rate does not deposit extra tokens into a holder’s account.
Common problem
Why did my raw token balance not increase?
This extension changes the display calculation. Raw token units and actual transfers remain distinct from the interest-adjusted presentation.
Network and protocol costs are separate. Your transaction review shows the current amounts.
