The original chain for USDC. Best for high-value transactions where security and liquidity matter most. Customers must already hold USDC. PYMSTR does not convert fiat.
Why Ethereum?

Gas fees of $2-10 are negligible on $1,000+ transactions. The security trade-off is worth it for high-value payments.
