Exchange identify MYKEY transaction

Use Parity / Geth to configure tracing to identify contract internal transactions. Take Parity as an example, you can use trace_transaction to get all traces of a transaction.(https://wiki.parity.io/JSONRPC-trace-module#trace_transaction)

Parity parameters example:

parity --cache-size=1024 --max-peers 100 --db-path /root/.parity --jsonrpc-interface "0.0.0.0" --jsonrpc-port 7001 --tracing on --jsonrpc-apis eth,net,personal,web3,traces
