USDC Contract Address: Official Addresses for Every Blockchain

• New to USDC? Read our complete USDC stablecoin guide.
  

• USDC is a fully collateralized stablecoin issued by Circle, always redeemable 1:1 for US dollars.
• Every blockchain has its own unique USDC contract address — using the wrong one can result in permanent fund loss.
• Always verify any USDC address against Circle's official developer documentation before sending funds.
• Testnet USDC addresses carry no real financial value and should only be used for development and testing.
• When adding USDC to MetaMask, make sure the contract address matches the network you are connected to.
• You can verify any USDC contract address on-chain using block explorers like Etherscan, PolygonScan, or Solscan.

How to Add USDC Token Address to MetaMask

• Open MetaMask and make sure you're connected to the correct network (e.g., Ethereum Mainnet or Polygon).
• Click "Import tokens" at the bottom of the Assets tab.
• Paste the correct USDC contract address for your chosen network — for Ethereum, use 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48.

• MetaMask will auto-fill the token symbol (USDC) and decimals (6) — verify these match before confirming.
• Click "Add Custom Token," then "Import Tokens" to complete the process.
• If you're on Polygon, use the Polygon PoS USDC address 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359 instead of the Ethereum one.
• Never use an address from unofficial sources — always verify against Circle's documentation or CoinGecko's token page.

Common USDC Wallet Address Mistakes to Avoid

• Sending ERC-20 USDC to a Solana address will result in permanent loss of funds, since the two networks are not cross-compatible by default.
• Using an old bridged USDC address (like USDbC on Base) instead of the native USDC address can cause transaction failures or send funds to the wrong contract.
• Confusing a USDT address with a USDC address is an easy mistake — always verify the token symbol before confirming any transaction.
• Sending USDC on the wrong network (e.g., Polygon USDC to an Ethereum wallet expecting ERC-20) may result in unrecoverable funds.
• Copy-paste errors are more common than you think — always verify the first and last 4–6 characters of a USDC wallet address before sending.
• Never trust a USDC contract address shared via social media, Discord, or email — scammers frequently impersonate Circle and other official sources.
