1. Verify the Mint before reading supply
Supply data belongs to a specific Mint address. If you inspect the wrong Mint, a correct supply number is still the wrong answer for the token you intended to verify.
- Copy the full Mint from a trusted source.
- Cross-check it on an explorer.
2. Understand raw supply and decimals
Token programs store supply as an integer. The decimals field tells interfaces where the decimal point belongs when displaying the amount to people.
For example, a raw amount and six decimals are displayed by dividing the raw integer by 10^6.
- Read supply and decimals together.
- Do not compare raw integers across tokens with different decimals.
3. Check whether supply can change
The current supply is only one part of the supply model. Mint Authority determines whether the configured authority can create additional units for a standard SPL Mint.
A revoked Mint Authority answers that permission question, but existing vesting, treasury or locked allocations still need separate review.
- Check Mint Authority.
- Read published token allocation and vesting rules.
- Separate total supply from circulating supply.
4. Separate total supply from market float
A project's total issued supply can be much larger than the amount actively circulating in public markets. Treasury, vesting, liquidity and reward allocations may not all be part of the immediate float.
Use on-chain data and published allocation information together instead of assuming total supply equals circulating supply.
- Total supply ≠ public float.
- Allocation ≠ immediate circulation.
- Verify market liquidity separately.
