The OpenFinance Network was created as a response to a fragmented alternative asset market, in which the lack of standardization and interoperability create a burdensome environment for issuers and investors alike. By creating a uniform protocol across the market, we are able to bring down clearing and settlement friction to a matter of seconds. It is with this intent that we are proud to announce our own security token contract, the Smart Securities Standard (S3) to the market.

When issuing new securities or tokenizing existing assets, the OpenFinance Network S3 token contract library allows for companies to issue security tokens in a compliant and streamlined fashion.

Smart Securities Standard (S3)

You can find the full S3 specifications on the OpenFinance Network Github page.

This library contains a series of modular contracts, meant to build off of each other, and fit the needs of specific regulation. You will find all the requirements of a compliant transfer, AML/KYC, investor accreditation, and bad actor checks. Our library will encompass all offerings of registered & restricted securities, including Regulation D, Reg S, Reg A+, & Reg CF. These offerings will allow an issuer to easily and compliantly create a security token capable of utilizing the full benefit of the OFN ecosystem.
