Liquidity Providers: Centralised and decentralised exchanges provide interfaces and use standards to make it easier to trade security tokens.
Validator System: The issuer must enforce KYC/AML and other regulatory rules. These restrictions can all be managed and validated with a compliance platform such as Tokeny.
Token Standards: So far the most adopted token standards are ERC20, ERC 725/735, and ERC1400. All of these standards work with Tokeny’s T-REX infrastructure.
Blockchain: Ethereum is currently the blockchain with the most complete ecosystem but there are other blockchain options such as Stellar and EOS.
