Bridge USDC to Native Tokens

With your bridge fully configured and collateralized, you can now transfer your 1 USDC from Fuji to your L1, where it becomes native gas tokens.

Reminder: You received 1 USDC from the Circle Faucet at the start of this chapter.

Connect to Fuji C-Chain

Switch your wallet to Fuji C-Chain (the source chain).

Verify you have:

1 USDC (from Circle faucet)
Test AVAX for gas fees

Bridge using the Token Transfer tool

Use the tool below to bridge your USDC:

Select your ERC20TokenHome as the source bridge contract
Select your NativeTokenRemote as the destination bridge contract
Enter 1 as the amount (or less if you want to keep some USDC)

Make sure you have:

Successfully registered and collateralized your bridge
USDC tokens in your wallet
AVAX for gas fees on Fuji

Switch to your L1 and confirm

Switch your wallet to your L1 and check your native token balance.

You should now have native tokens on your L1! These are backed 1:1 by the USDC locked in the ERC20TokenHome on Fuji.

What Happened

Your 1 USDC was locked in the ERC20TokenHome on Fuji
An ICM message was sent to your L1 via the relayer
NativeTokenRemote called the Native Minter precompile to mint native tokens
1 native token was credited to your address on your L1

Bridging Back

To bridge native tokens back to USDC:

Switch to your L1
Use the Token Transfer tool with reversed source/destination
Native tokens will be burned and USDC released on Fuji

Summary

You've successfully:

Got 1 USDC from the Circle faucet
Created an L1 with Native Minter enabled
Deployed ERC20TokenHome on Fuji for USDC
Deployed NativeTokenRemote on your L1
Registered and collateralized the bridge
Bridged 1 USDC → 1 native token

Your L1 now uses USDC as the native gas token!

Next Chapter

In Chapter 2, you'll learn the reverse: exporting your L1's native token to C-Chain as an ERC-20.
