# Post-diabetes

### Abstract:

Post-diabetes is a secondary marketplace that runs on top of Pre-diabetes' tokenized vaults. Because collateral is locked up throughout the vault cycle, this secondary market allows for real-time position entry and exit via an order bookkeeping system. Transactions are carried out by signed transactions from the taker and are carried out on-chain utilizing contracts from 0x Protocols after being finalized by the taker. These contracts are tried and tested, guaranteeing that users have a pleasant trading experience.
