Sandbox Migrated from Solana Testnet to Devnet

We've migrated our Sandbox from Solana Testnet to Solana Devnet. Our change to Devnet should minimize outages and provide a seamless testing experience.



We are excited to announce Flow USDC is officially here! With Circle APIs there is no easier way to on ramp fiat into Flow USDC, off ramp Flow USDC to fiat or swap Avalanche, Algorand, Ethereum, Hedera, Solana, Stellar, and TRON USDC to Flow USDC.
