Payments on the autonomies marketplace are made with USDC, a cryptocurrency that keeps the peg against the U.S dollar. You can read more about how USDC works here.
Once installed and set up, open the MetaMask application directly from your browser. To load your account with USDC on Polygon, you can proceed as follow:
There you go, the transaction is on its way and should appear in your MetaMask wallet in a few minutes.
MATIC and other Polygon based assets can be purchased the same way.
MATIC is similar to Gas in Ethereum and is needed to execute transactions on Polygon. The difference being that it’s (very) cheap as opposed to gas on Ethereum. 5 MATIC should let you execute around five thousands transaction - enough to start a proper collection on Autonomies!
If you already hold USDC on Polygon, you can visit https://wallet.polygon.technology/gas-swap to top up your wallet with MATIC using USDC.
Polygon’s technology allows you to exchange USDC and other tokens in exchange for MATIC without having to pay any gas fees.
Within a few seconds some MATIC tokens should be visible from your MetaMask account. You’re all set!
