This release unlocks access to Polygon mainnet, increases API support for Polygon Mumbai testnet and provides new APIs for tier-two QRC-20 smart contract functions.
04 April 2022
Overledger 2.2.3 provides new access to Polygon mainnet and increases API support for Polygon Mumbai testnet. It also introduces new APIs for tier-two QRC-20 smart contract functions to issue payments and easily retrieve a list of supported tokens from Overledger.
As part of this release, we have extended ERC-20 token support for the top five tokens on Polygon mainnet, including:
- Wrapped Ether (WETH)
- USD Coin (USDC)
- Tether USD (USDT)
- Wrapped Matic (WMATIC)
- Dai Stablecoin (DAI)
Developers will also be able to use our API for QRC-20 smart contract invoke to interact with smart contracts on the Polygon Mumbai testnet and mainnet networks. This release completes support for all available Ethereum-based functions for Polygon.
This release also includes two new APIs on Overledger; the first makes a QRC-20 payment as a secondary account owner on behalf of the account owner. The second API enables developers to retrieve a list of supported ERC-20 and QRC-20 tokens and their supported functions.
