Why does IOB circulating supply differ from the locked amount Vestream shows?▼
Circulating supply is the amount of IOB that is freely tradable on the open market. Total supply includes every token ever minted – including amounts still locked in vesting contracts, team allocations, treasury reserves, and other non-circulating pools. Vesting unlocks move tokens from the "locked" bucket into circulating supply on a predetermined schedule, which is what Vestream tracks.

IOB is deployed on Arbitrum. The contract address is 0xc720…134d (full address: 0xc720d3a15e97347ec501fd3011613c5b9337134d). You can verify it on Arbiscan: https://arbiscan.io/token/0xc720d3a15e97347ec501fd3011613c5b9337134d
