On September 15, 2022, Ethereum successfully completed The Merge, transitioning to a more energy-efficient proof-of-stake (PoS) infrastructure, which was a significant milestone for the platform and blockchain technology at large. During this period, Circle paused its minting, redeeming, and sending of USD Coin (USDC) and Euro Coin (EUROC) on Ethereum, but these activities resumed smoothly post-Merge. In the 24 hours following the transition, Circle reported $671 million in USDC minted and $1.1 billion in USDC redeemed without incident, underscoring the seamless integration of their operations with the upgraded Ethereum network. Despite a brief service interruption, The Merge underscored the resilience of blockchain technology and marked USDC as the largest ERC-20 asset, playing a vital role in the DeFi innovation on Ethereum. Circle emphasized the importance of vigilance against scams on the unsupported Ethereum proof-of-work (PoW) chain and highlighted the future potential for innovation and reduced energy consumption on the new PoS network.
