##  Let's go! First, we create wallets.

printf 'done!\nWallet 2 = %s\n\n' "$WALLET2"
sleep "$WAITING_TIME"

##  Then, we start instances.

printf 'Start two corresponding instances... '

readonly INSTANCE1=$(start_instance "$WALLET1")
readonly INSTANCE2=$(start_instance "$WALLET2")

printf 'done!\n  Instance 1 = %s\n  Instance 2 = %s\n\n' "$INSTANCE1" "$INSTANCE2"

sleep "$WAITING_TIME"

##  Then, we lock the secret word.

printf 'Lock secret word "%s" in instance 2... ' "$SECRET_WORD"

curl -H "Content-Type: application/json" \
  --request POST \
  --data '{"amount":{"getValue":[[{"unCurrencySymbol":""},[[{"unTokenName":""},90]]]]},"secretWord":"'$SECRET_WORD'"}' \

printf 'done!\n\n'

##  Finally, we guess the secret word.

if $GUESS_RIGHT; then
    right=right
    prefix=
else
    right=wrong
    prefix=not
fi

printf 'Guess %s in instance 1... ' $right
