How to Purchase Cardano (ADA) Using Optimism (OP) in China

To buy Cardano using Optimism, first, find a cryptocurrency exchange that supports the ADA/OP trading pair, such as YouHodler. Create an account, complete the KYC process to verify your identity, and deposit your OP into your exchange wallet. Locate the ADA/OP pair on the trading platform and place an order to exchange your Optimism for Cardano. If the ADA/OP pair is unavailable, you can first exchange Optimism for a stablecoin like Tether (USDT) or a fiat currency such as CNY, then trade that for Cardano. Be mindful of potential exchange fees, which vary by platform and can impact the overall cost of your transaction.
