What is Soulbound NFT (SBT)?

NFT on TON can work with the Soulbound NFT (SBT) standard. What is it? This is a special kind of unique token that cannot be transferred or sold, as it remains forever tied to the wallet. Its purpose is, for example, to display the achievements of a particular wallet, confirm certain statuses (KYC, ownership of a temporary subscription, etc.) and so on.

This standard works on the principle that an NFT has only one owner and cannot be transferred anywhere. This expands the ways in which artists and developers can use NFT on TON.

An SBT can also be burned by its owner. The standard itself is described in TEP-85: https://github.com/ton-blockchain/TEPs/blob/master/text/0085-sbt-standard.md
