Check balance of Alice

mesg-cli service:execute plasma-watcher getUTXOs --data address=$ALICE_ADDRESS

Alice has no UTXO to spend

Alice deposit

node scripts/deposit.js 100000

Wait for utxo to be added on the childchain

mesg-cli service:execute plasma-watcher getUTXOs --data address=$ALICE_ADDRESS

Alice has one UTXO

Prepare to exit

Now you will try to exit the first UTXO that you had after your deposit. You already spent this UTXO and send all the amount to Bob so this is an invalid exit.

mesg-cli service:execute plasma-watcher getUTXOs --data address=$ALICE_ADDRESS | jq ".utxos[0]" > utxo.json
mesg-cli service:execute plasma-watcher getExitData --json utxo.json > exit.json

Transfer some value to BOB

mesg-cli service:execute plasma-watcher sendTransaction --data from=$ALICE_ADDRESS --data to=$BOB_ADDRESS --data amount=100000 --data privateKey=$ALICE_PRIVATE_KEY --data utxos="[$(cat utxo.json)]" 

Wait for transaction

Check Alice UTXO

mesg-cli service:execute plasma-watcher getUTXOs --data address=$ALICE_ADDRESS

Alice has no UTXO to spend

Exit the initial UTXO

Now you will try to exit the first UTXO that you had after your deposit. You already spent this UTXO and send all the amount to Bob so this is an invalid exit.

node scripts/exit.js "$(cat exit.json)"

Wait for it

After few seconds/minutes, the plasma-watcher should emit a new event invalid_exit and the application should catch this event and automatically create and submit a challenge to the root chain
