Pump.fun defaults to V3 with per-request V1/V2/V3 overrides. See version configuration, multi-hop examples and simulation limits.
Examples are updated for the current Python SDK API. Basic protocol demonstrations contain synthetic accounts and are intentionally dry-run only; setting RUN_LIVE_EXAMPLES=1 makes them fail closed.
Official Pump.fun/PumpSwap multi-hop buy and sell: pump_multi_hop; python -m examples.pump_multi_hop --help. Four workflows and settlement.
cached_trade accepts optional pump_route JSON settings for Auto / Official / Sequential; see execution selection. It reports aggregate metadata when official execution is selected.
pip install -e .
python examples/trading_client.pyFor a live bot, start from low_latency_bot.py, read ../docs/USAGE.md#low-latency-bot, and provide real parser, balance, quote, and state-refresh adapters. PRIVATE_KEY accepts a base58 64-byte secret key or a JSON array containing 64 bytes.

fixtures/batch2_cpmm_buy_20261003.json 和 batch2_cpmm_sell_20261003.json 是完整冷启动快照，可交给本仓 cached_cpmm 示例离线构建独立买入/卖出；三语言 wire 一致。对应 batch2_cpmm_simulations_20261003.json 保存两笔成功主网模拟，可供 parser 的 simulation_routes 示例读取。没有真实发送。保存快照仅供复现，执行新交易前须由冷启动/订阅提供当前状态；构建与报价不调用 RPC。
缓存 CPMM 现检查 vault 的 token authority，prepare 拒绝零最小到账。CLMM/DLMM 可扫描完整合法稀疏范围；bitmap 证明空区间不需要虚构账户，已初始化 array 缺少订阅数据仍明确拒绝。实时账户输入通过 sol-parser-sdk 的 gRPC 接入；见 ../docs/USAGE.md#grpc-cache。新 array 发现、静态账户 freshness 和分叉一致性仍由 gRPC 订阅集成策略处理。
当前银行模拟与跨语言成交检查见 ../docs/USAGE.md#simulation-matrix，包含 --simulation-out 保存证据和 parser 离线验收流程。
