Cryptocurrency exchange Coinbase (COIN) bought a minority stake in stablecoin issuer Circle Internet Financial. The two companies also dissolved their Centre Consortium partnership, which issued USD Coin (USDC), the world’s second-largest stablecoin. As part of the move, Circle will bring issuance and governance of USDC fully in-house. Also, six more blockchains will gain native support for USDC, which is pegged at $1, bringing the total number of supported blockchains to 15. Coinbase and Circle, in a blog post and interviews with CoinDesk, did not disclose the size of the stake acquired by Coinbase. Coinbase did not give Circle cash for the stake, according to a person familiar with the matter.
