Wrapped TON (Tonco) wallet

What is Wrapped TON (Tonco) (WTTON)?

On TON, the native Toncoin and the jetton standard are two different things. Contracts built to receive jettons cannot take Toncoin directly, so a wrapper mints a jetton that represents it one for one. WTTON is that wrapper as used by the TONCO exchange, which runs concentrated-liquidity pools on TON and needs a jetton on both sides of a pair.

One consequence is worth stating plainly: TON has more than one Toncoin wrapper in circulation, issued by different protocols. They are separate jettons. A pool or contract expecting one will not recognise another, even though both describe themselves as wrapped TON.

Holding a jetton on TON also has its own shape. Your balance does not sit in a shared contract ledger; every holder gets their own small jetton wallet contract, deployed the first time the token reaches your address. Deploying it costs a little Toncoin, transfers carry Toncoin forward for gas, and contracts on TON pay storage rent, so leaving some Toncoin in the wallet keeps everything responsive.

Supported networks in Tangem (1): TON. The key that controls that jetton wallet is created inside the card's secure chip and never comes out of it, and a second card holding the same key is the whole backup procedure; writing down a seed phrase is available but not required. Storage that quiet suits a wrapped position you open once and leave in place.
