New release of Quant’s blockchain gateway introduces smart contract creation

Quant, a provider of enterprise-grade interoperability for the secure exchange of information and digital assets across any network, platform, or protocol, announced newly announced a new release for its Overledger blockchain gateway, which provides interoperability between blockchains with a single API.

Overledger 2.1.7 lets users create smart contracts for payments using tokenized money with an API. Additionally, Overledger natively supports twelve programming languages, so no additional programming or blockchain language is required. Also, QRC20 smart contracts can be deployed straight to the Ethereum Ropsten testnet directly by the UI.

This new smart contract functionality in Overledger is an important milestone…

QRC20 smart contracts can act as programmable money in an interoperable blockchain payment system.

v2.1.7 allows customers to deploy smart money and perform basic payment operations with REST/JSON APIs, including:

• ‍Create a QRC20 smart contract on the Overledger User Interface (UI) – Developers can set the attributes of their smart contract on the UI. Overledger will then generate the smart contract byte code to deploy the smart contract via Metamask.
• ‍Make a credit transfer to initiate a QRC20 token payment – Developers can use a dedicated API to create a QRC20 token payment. With this API, developers can set their token unit and payee address. Overledger then issues the request payload for signing and execution.
• ‍Initiate a debit transfer to pull a payment of the QRC20 token – Developers can apply a dedicated API to generate a QRC20 token payment. Then, developers can input their token unit and payee address with this API. Overledger will then convert the request payload for signature and execution.
• ‍Pre-approve a debit transfer to pull a payment of the QRC20 token – Developers can use a dedicated API to create a QRC20 token payment. Then, developers can easily input their token unit and payee address. Finally, Overledger will convert the request payload for signing and execution.

Once the QRC20 contract is deployed, a new set of QRC20 APIs will be automatically updated on Overledger to support the newly generated QRC20 token.

“Quant’s enterprise-grade smart contracts are highly secure and tested, developed by our team of PhDs and verified with external experts. They conform to the ERC20 standard for smart contracts and are production-ready for financial services applications. Quant is building additional smart contract templates and functionality in upcoming Overledger releases for payment and non-payment use across multiple blockchain platforms.”
