Polygon (MATIC) is a scaling solution for the Ethereum blockchain that aims to provide faster and cheaper transactions. It is a parallel blockchain that users can "bridge" their tokens to and interact with through compatible wallets such as MetaMask or Coinbase Wallet. The network is secured by a Proof-of-Stake consensus algorithm and its native currency, MATIC, is used to pay for transaction fees and can be staked to earn rewards. Polygon was launched in 2020 by Ethereum developers and has attracted several leading DeFi applications to its network, including Uniswap, Aave, and PoolTogether.
