Describe your question in detail.

Is there any good example on how to manage payment in Smart Contract?
I wonder if I should use coin or FA.

Questions:

• How to find the address of APT token object or coin?
• How to find the address of USDC token object FA?

Use cases:

• Users send APT tokens and in return, the SC sends an NFT.
• Users send USDC tokens and the SC sends an NFT.

What error, if any, are you getting?

1. APT FA metadata object address is 0xA
2. I believe zUSDC / whUSDC is Coin standard -- here's an explorer link with relevant info

Ideally, since we're in the middle of migration, you'd support both Coin and FA. Find more details about the migration in the docs.

Although, you want to verify if there's sufficient liquidity or CEX support before converting coins to FA on mainnet.
