Overledger 2.2.0 improves performance and data quality across APIs
17 February 2022
Quant’s Overledger is the world’s first blockchain-agnostic API gateway. In Overledger 2.2.0, we enhanced the performance of the gateway and improved data consistency across our APIs. There are no new features added within this release.
Quant has a steady product roadmap for Overledger to enable customers to create enterprise-grade smart contracts that function across blockchains, smart tokens for digital asset management and tools to analyse multi-DLT transactions.
Developers should note that due to Overledger’s APIs changing in this release, any mDapps created in earlier versions of Overledger should be retested.
Please see the Release Notes 2.2.0 for full details of the changes in version 2.2.0.
