SegMint

SegMint grew out of VanEck's digital asset research and uses a Lock and Key model to split rights over self-custodied assets. Assets sit in a contract vault, the lock, and the holder issues ERC-1155 keys to others that map to view, use, transfer or income rights; keys trade separately and can be revoked at any time.

Supporting features include the Safes multisig vault, an NFT minting tool that lets a creator attach usage terms, and token-gated permissions built on delegation. The platform first launched in February 2024 as a fractionalisation marketplace for collectibles, then shifted toward supplying other institutions with backend infrastructure for tokenising, authenticating and trading physical collectibles; the original fractionalisation contracts keep running and listings from several real-world asset issuers are aggregated alongside them.
