The implementation

add a new mutation type to wrap the other mutation

Lines 72 to 78 in 0a95405

    
           enum PayloadType { 
        
               QuerySessionPayload =0; 
        
               DatabasePayload = 1; 
        
               MintCreditsPayload = 2; 
        
               // a evm chain request 
        
               TypedDataPayload = 3; 
        
           }

the types of typed data

           let json = serde_json::json!({ 
        
             "EIP712Domain": [ 
        
             ], 
        
             "Message":[ 
        
             {"name":"payload", "type":"bytes"}, 
        
             {"name":"payloadType", "type":"string"}
