I’m getting the same error. This is what I got while doing a transaction with MUMBAI testnet.
`MetaMask - RPC Error: [ethjs-query] while formatting outputs from RPC ‘{“value”:{“code”:-32603,“data”:{“code”:-32000,“message”:“transaction underpriced”}}}’
How do I increase the gas price?
creation of XCy errored: [ethjs-query] while formatting outputs from RPC ‘{“value”:{“code”:-32603,“data”:{“code”:-32000,“message”:“replacement transaction underpriced”}}}’
This could happen if somehow the nonce of the transaction you’re trying to perform got to be the same as your last transaction’s nonce. If that’s the case, the solution would be incrementing the nonce for your current transaction by 1.
i m getting same error today on mumbai polygon even increasing nonce. gas fee also not returning properly. please suggest someone if any found solution. i waste a lot of time on it for found solution
