TON Jetton

A Jetton is the fungible token standard on TON, realized as a master contract plus a separate wallet contract holding each owner's balance.

TON implements fungible tokens as Jettons using a sharded design: a master contract defines the token, and each holder has a dedicated Jetton wallet contract that stores their balance. Transfers pass asynchronous messages between wallet contracts rather than updating one shared ledger, which scales across TON's sharded architecture but changes how you index balances. You resolve a holder's wallet contract address to read their balance. Our TON archive API decodes Jetton transfer messages and resolves wallet contracts, so you can track balances and flows across the standard's distributed layout.
