Consider we have a ETH keypair in the keystore inserted using this command
curl -H "Content-Type:application/json" -d '{"jsonrpc":"2.0","id":1,"method":"author_insertKey","params": ["eths","0x606640b4efd5a1a0bc9839dfce7a7bb5a0c1402d8d02cbee9dabe5d88f977640","0x0209bb17d85c86ad4812103248b6b73e67f96ea66829c3b18f4d1b5df2c72cab63"]}' http://127.0.0.1:9936
How we can access this keystore in a substrate pallet to sign an Ethereum transaction?
You can not sign from your on chain code. Your on chain code needs to be deterministic. If you don't provide your private key to every node in the network, they could not import the block and while doing this, running the signing code again.
