//Why USDC on Ethereumoverview

Why Ethereum?

USDC on Ethereum is the most liquid and widely held version of USDC. Ethereum mainnet has the highest security guarantees and deepest DeFi ecosystem.

Ethereum is the most battle-tested blockchain with the highest total value locked. Gas fees ($2-10) make it ideal for larger transactions where security is paramount.

USDC on PYMSTR.

Maximum Security

Ethereum has the highest validator count and longest security track record of any smart contract platform.

Deepest Liquidity

Most USDC exists on Ethereum mainnet. Your customers likely already hold USDC here.

Best for Large Transactions

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

1% Flat Fee

PYMSTR charges 1% regardless of chain. Network gas fees are separate and paid by the customer.

Yes. PYMSTR supports USDC on Base ($0.05), Polygon ($0.01), and Arbitrum ($0.10). Offer multiple chains and let enforced payments ensure customers use the right one.

About 15 seconds for transaction confirmation. Funds arrive in your wallet immediately after confirmation.

USDC is issued natively on each supported chain by Circle. The value is identical ($1). The difference is gas fees and confirmation speed.
