To use LinQup as a supporter, you need USDC on the Polygon network. This guide covers all methods.

What is USDC?

USDC is a stablecoin - cryptocurrency that's always worth $1.

Why USDC?

✅ Stable ($1 = 1 USDC always)
✅ No crypto price volatility
✅ Easy to understand
✅ Widely supported
✅ Backed by real USD reserves

Different from:

Bitcoin - Price fluctuates wildly
Ethereum - Price changes daily
Other cryptos - Too volatile for subscriptions

Step 3: Bridge USDC

From: Select your current network (e.g., Ethereum)
To: Polygon

Step 4: Wait

Ethereum → Polygon: ~7-10 minutes

Gas fees: Depends on source chain. Ethereum is expensive ($5-20), other chains cheaper.

How Much USDC Do I Need?

Calculation

For streaming $X/month:

1 month = $X
3 months = $3X
6 months = $6X

Example: $10/month stream

$10 USDC = 1 month
$30 USDC = 3 months
$60 USDC = 6 months

Recommendations

💡 Start small: $10-20 to test

💡 Budget monthly: Add $X every month

💡 Multiple creators: $X × number of streams

Don't Forget: MATIC for Gas

You also need tiny amount of MATIC (~$0.50) for transaction fees.

Getting MATIC:

Same methods as USDC
Polygon faucet (free small amount)
Swap USDC → MATIC on QuickSwap

Verifying You Have USDC

Check in MetaMask

Open MetaMask
Switch to Polygon Mainnet
Look for USDC in token list

Don't see USDC? Add it manually:

Token address: 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359
Symbol: USDC
Decimals: 6

Check on Polygonscan

Visit polygonscan.com
Enter your wallet address
Click "Token" dropdown
Look for USDC

Next Steps

Now that you have USDC:

Convert to USDCx - For streaming
Start Supporting - Use it!

Common Issues

"Insufficient funds" error

You need MATIC for gas fees, not just USDC.

USDC on wrong network

Make sure it's on Polygon, not Ethereum. Check network in MetaMask.

Can't find USDC in wallet

Add the token manually (see "Verifying You Have USDC" above).

Bridge taking too long

Ethereum → Polygon can take 10-20 minutes during high traffic. Be patient.

Safety Tips

⚠️ Always verify:

You're on Polygon network
Correct USDC contract address
Website URLs before connecting wallet

⚠️ Start small:

Test with $10 first
Make sure everything works
Then add more

⚠️ Beware of scams:

Only use official bridges/exchanges
Never share your seed phrase
Double-check all addresses
