Sending GLM from the Ethereum Mainnet to Polygon and back.
Since the Beta.4 release of Golem, Polygon network became the default platform for payments between Golem requestors and providers.
While Polygon itself offers countless opportunities in the form of distributed exchanges and other DeFi platforms, one might still want to move their hard-earned GLM tokens to the safety of the Ethereum Mainnet, or conversely, get their mainnet GLMs to Polygon to pay for tasks on Golem.
Whatever your need, there may come a time when you'd like to send your GLMs one way or the other and the instructions below will serve as your guide.
Configure the Metamask wallet extension for Chrome / Firefox / Opera and add your wallet.
Choose the required amount (Minimum = 1 MATIC) and follow the instructions (See the image below)
3. You can check how much MATIC you have using the "Assets on Polygon" tab
Just for reference, currently (as of March 23rd, 2022), the transaction fees for an ERC-20 transfer on Polygon oscillate around slightly above 0.001 MATIC so converting even the minimal value of 1 MATIC will get you enough to pay gas fees of hundreds of GLM transfers.
