pumpfun-bonkfun-bot_github/tools/live_v2_round_trip.py

"""Execute one real buy_v2 + sell_v2 round trip on mainnet.

WARNING: this submits real transactions and spends real funds. It exists to
cover the last gap the simulation scripts cannot reach — actual submission,
confirmation, and the post-trade accounting that parses a confirmed
transaction. Keep BUY_AMOUNT_SOL tiny.

Uses the bot's own PlatformAwareBuyer / PlatformAwareSeller, so a pass here
means the production path works end to end.

Usage:
    uv run tools/live_v2_round_trip.py            # needs confirmation
    uv run tools/live_v2_round_trip.py --yes      # skip the prompt
