Depending on which cryptocurrency or wallet you're using, follow these steps:
For Ethereum-based transactions (USDC, PYUSD, ETH): Use www.etherscan.io. Enter your Ethereum wallet address in the search bar, locate the relevant transaction, and find the transaction hash (TXID).
For Bitcoin transactions (BTC): Use www.Blockchain.com. Enter your BTC wallet address to find the transaction and its corresponding hash.
In your wallet or exchange (Binance, Coinbase, MetaMask): Navigate to your wallet’s transaction history or activity page. Locate the transaction you want to trace, and you'll see the "Transaction ID" or "Hash" labeled for each transaction.
