When your transactions fail to process due to the “Internal JSON-RPC error, the RPC used in your wallet is causing the issue.
To address the issue, using Arbitrum as an example, you can go to Wallet Settings > Networks > Arbitrum > Change “New RPC URL.”
You can use https://chainlist.org/chain/42161 as a reference and try different listed RPC URLs until your transaction can be processed.
If you trade on DEXes frequently, it’s recommended to use high-performance RPC from https://www.alchemy.com/ or https://rpc.ankr.com/arbitrum for a stabler experience.
When the error details is empty, it’s usually indicating RPC issue as well. Please follow the Internal JSON-RPC error fix on how to address this issue.
This issue is caused by the gas fee limit you set in the wallet being too low. Please try to increase the gas limit and try the transaction again.
This error means you currently have insufficient gas in your wallet to process any transactions. Please transfer more gas tokens (like $ETH on Arbitrum) to your address and then proceed with the transaction.
This error means Gains liquidity becomes insufficient to support your position after placing the order. Please try lowering the position size and then open the position again.
