Recently, a leading exchange's Web3 wallet launched the 44th IDO project (ZTC token) with a participation threshold of 241 points. The event is scheduled for January 7th from 4:00 PM to 6:00 PM. For friends who want to rush to sell right when it opens at 6 PM—advance authorization is key.
What are the benefits? Simple: after receiving the token at 6 PM, you can exchange it directly in the wallet without waiting for on-chain confirmation. In other words, you're seizing those few seconds of time difference.
How do you do it? The steps are actually straightforward.
First, you need to find the ZTC contract address: 0x87033d521f1a5db206860f2688ca161719f85187. Open this contract, click "Contract" in the menu bar, then switch to the "Write Contract" page. Next, click "Connect to Web3" and use your wallet to scan the QR code to log in.
Then find the approve function. In the spender field, enter the authorization address: 0xb300000b72DEAEb607a12d5f54773D1C19c7028d (a leading exchange's DEX). The key is the value field—fill in 0xffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff, which means unlimited authorization. Click Write, and you're done after spending a few cents in gas fees.
Once the authorization is approved, when you receive the token at 6 PM, you can immediately swap it in the wallet with a smooth process. When selling, it's recommended to set slippage around 20% to handle market volatility.
One reminder: when scanning the QR code to log in, you may need to open relevant tools to connect. This trick is quite useful for traders who want to capture the opening day profits.
