You MUST use a web-enabled Ethereum wallet to make payments using ERC-20 tokens. Metamask is highly recommended.
You MUST have enough ETH tokens in the Ethereum wallet from which you will be making a payment to cover the required gas fees.
Gas fees on Ethereum can be VERY expensive. There is nothing Splinterlands can do about this. Please make sure you understand the fees required to make your payment.
The FIRST TIME you make a payment with the specified ERC-20 token, you will be asked to submit a transaction to approve payments using that token in Splinterlands. This transaction will also require gas fees paid in ETH.
If you receive an error making the payment, please check the following:
You have Metamask or another web-enabled browser wallet available, unlocked, and connected to the Splinterlands website.
Your wallet is connected to the Ethereum Mainnet and not another network like Binance Smart Chain.
You have enough ETH tokens in your wallet to cover the required gas fees.
You have enough of the specified ERC-20 token required to make the payment.
