Polygon Labs has deprecated the ‘Polygon Edge’ used to build Dogechain, which uses Dogecoin as gas.

This was presented as a way to add support for Ethereum-style smart contracts, which could in turn facilitate new DeFi protocols as well as NFTs. The original Dogecoin blockchain lacked smart contract support. It was an early clone of Bitcoin as it was a fork of Litecoin. Bitcoin launched in 2009, a few years before Ethereum, ushering in a new era of smart contracts. .
