Quant’s Overledger is the world’s first blockchain-agnostic API gateway. In version 2.2.1, we have added support for Polygon, an Ethereum-compatible network, providing faster transactions and lower costs for users. The full, standardised Overledger API is now supported on the Polygon scaling solution.
Polygon solves common blockchain pain points, offering low gas fees and high speeds without sacrificing security. To date, there are more than 6,000 dApps already using this system. In numbers, a transaction that costs traders USD 50 and takes minutes on Ethereum, now costs less than a cent and is instantaneous on Polygon.
All Overledger functions available for Ethereum can now be performed on Polygon testnet, such as creating a MATIC transaction, searching, monitoring an address and more. Support for Polygon mainnet will be available shortly.
Polygon integration is part of Quant’s product roadmap for Overledger, providing seamless interoperability of smart tokens across multiple DLTs and blockchains.
Please see the Release Notes for full details of the changes in version 2.2.1.
