Jetton
Token standard on the TON network — TON's analogue of Ethereum's ERC-20. Used for USDT, NOT, and thousands of other fungible tokens.
Aliases: ton token, fungible token
Jetton is the fungible-token standard on the TON blockchain. Functionally it plays the role ERC-20 plays on Ethereum — issuance, balances, transfers — but the implementation is fundamentally different.
Architecture
Unlike ERC-20, where every balance is stored inside one smart contract, jettons use a separate contract per holder:
Jetton Master— the master contract describing the token (name, symbol, total supply).Jetton Wallet— a dedicated contract for each holder. Every user has their own wallet contract.
The advantage is parallelism: a transfer between two users does not write to a shared state, so transfers can be parallelised across shards. This is what gives TON its throughput edge.
Major jettons
- USDT (TON) — Tether’s native USDT issuance on TON, launched in 2024. Most stablecoin volume on the chain runs through it.
- NOT (Notcoin) — token from the Notcoin mini-app, listed on major exchanges.
- DOGS, HMSTR, X, BOLT — tokens from other large-audience mini-apps.
Using jettons
All major wallets (Tonkeeper, MyTonWallet, Wallet) support jettons out of the box. When receiving an unknown jetton, the wallet labels it “unverified” — that’s expected; verification happens through TON Foundation’s reference list.
