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

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