A developer exploring Solana's Token-2022 Program discovered that tokens can function as interest-bearing savings accounts, enforce compliance through frozen states, and serve as revocable digital credentials. These capabilities go far beyond simple value transfer, reshaping how blockchain assets can be used.
Interest-Bearing Tokens
Using the Interest-Bearing Extension, the developer created a token whose displayed balance grows over time without changing the raw on-chain balance. Instead of minting new tokens, wallets calculate the interest-adjusted balance using the interest rate and elapsed time. This mirrors how modern banking apps show accrued interest.
Compliance by Default
Another extension, Default Account State, sets new token accounts to a Frozen state by default. No one can receive or transfer tokens until the account is explicitly approved. This aligns with regulated financial systems and KYC workflows, making tokenized assets compliance-ready.
Non-Transferable Credentials
By combining Non-Transferable, Permanent Delegate, and Metadata extensions, the developer built a revocable digital credential. The credential stays in one wallet, cannot be transferred, but can be revoked by the issuer. This models real-world certificates, employee badges, and professional licenses.
The developer concluded that blockchain tokens are programmable digital assets capable of representing financial products, regulated assets, memberships, and digital identities—a shift from viewing them as mere on-chain balances.
