KYC Select

Built-in optional regulatory compliance into open trading infrastructure

Within the Swarm Market's dOTC v2 trading infrastructure, offer makers can now require counterparties to be qualified and limit offers to only be taken by qualified counterparties. Offer makers can now choose from a selection of KYC/AML service providers.

This feature provides an additional compliance layer that sits on top of open and permissionless infrastructure, to provide fully regulatory institutional trading.

Qualifiers and KYC providers can very simply implement their own Authorization smart contract interface (requiring just one function) in order to provide their own qualification graph for offer makers to select from. See the technical implementation below.

Technical implementation:

The dOTC platform simply requires the presence of a single function isAccountAuthorizedto which a wallet address is passed, returning a true or false response, indicating whether the wallet address has been qualified. The Authorization contract can further interact with any other on-chain or off-chain logic to check the status of the wallet address.
