The Singapore High Court has allowed financial investigation firm Intelligent Sanctuary (iSanctuary) to attach nonfungible tokens (NFTs) containing a legal document to cold wallets associated with a hack, according to United Kingdom-based iSanctuary and local press accounts.
A court-issued worldwide freeze order was tokenized as soulbound NFTs and attached to the wallets in question. The NFTs will not prevent transactions with the wallets but will serve as a warning to counterparties and exchanges that the wallets were involved in a hack. In addition, iSanctuary claimed it has devised a means of tracking funds leaving the wallets, thanks to the NFTs. The NFTs will be permanently attached to the wallets.
