Circle has launched Paymaster, a stablecoin payment solution, on Ethereum's Arbitrum and Base, allowing $USDC payments for gas fees. This eliminates the need for native tokens like $ETH, enhancing user experience and reducing transaction failures. Circle plans to expand Paymaster to other blockchains like Ethereum, Polygon PoS, and Solana. A 10% gas fee charge is temporarily waived until June 30 to encourage adoption. Additionally, Circle acquired Hashnote, focusing on integrating traditional finance with blockchain technology, highlighting its growth strategy in the digital asset market.
