Unleash the simplicity and flexibility of Overledger technology


Overledger is available in a variety of formats to meet enterprise needs across a range of scenarios. The emphasis is always on simplicity, security and performance.

Overledger Enterprise - SaaS Edition

In this, the simplest, scenario, customers use the Quant hosted and managed Overledger gateway. Quant runs Overledger 24x7 and maintains a farm of DLT nodes on different public and private DLTs. We can also run and manage DLT nodes on your own private DLTs, or any regional or global consortia you belong to.

Overledger Enterprise - Customer Cloud Edition

For those who need more control, we also offer Overledger for cloud environments. This provides “one button ” installation on an AWS or Oracle Cloud Infrastructure.

Overledger Enterprise - Customer Server Edition

We can also install Overledger in your own datacentre, with full 24x7 support and extensive testing.

Overledger Enterprise - Marketplace Edition

Development instances of Overledger are available through the AWS Marketplace, Oracle Cloud (early 2021), and will be available through other cloud marketplaces in 2021. Our 24x7 DLT Node Farm provides DLT access.
