Version 0.3.0.
Verified with unit tests, surfpool, and mainnet buy-and-sell round trips on every venue.
Adds Raydium LaunchLab and CPMM support for buy, sell, and info. Routing selects LaunchLab or CPMM based on pool and migration status, and supports Token-2022 transfer fees.
Updates bonding-curve trading to cap sells at the amount payable from real reserves and report tokens remaining when a buy exceeds the curve’s supply.
Updates migrate_v2 instruction construction with PumpSwap’s boost-vault authority and quote-token account. The added protocol test checks the 29-account instruction.
Separates protocol instruction construction, core RPC and trade orchestration, and command-level routing and output.
Funds and transaction paths
This PR changes code paths that construct and send Solana transactions for LaunchLab and CPMM swaps, curve trades, and migrations. It also changes account derivation and account ordering for migration instructions. No wallet credential-handling change is described in the supplied evidence.
Verification
Tests and Surfpool integration tests were added. Completed test or CI results are not available.

PumpSwap creates the pool's boost vault during the migration and reverts

Walkthrough
This update adds Raydium LaunchLab and CPMM protocol and trading support. It changes trade routing and token information output, adds PumpSwap migration accounts, and caps bonding-curve sells at available real reserves.
Adds LaunchLab and CPMM address derivation, account parsing, fee calculations, and swap instruction builders. The migration instruction adds the boost-vault authority and quote-token account. Protocol tests and fixtures cover these changes.
Adds pool discovery, buy and sell operations, dry-run quotes, and pool information for LaunchLab and CPMM. The code handles quote assets, transfer fees, balances, slippage, and graduated pools.
Caps sells at the amount payable from real quote reserves and reports retained tokens. Buys that exceed remaining curve tokens return exceeds_curve.
Venue routing and token information src/pumpfun_cli/commands/trade.py, src/pumpfun_cli/commands/info.py, src/pumpfun_cli/core/info.py, src/pumpfun_cli/core/pumpswap.py, tests/test_commands/test_trade_cmd.py, tests/test_commands/test_human_output.py, tests/test_core/test_info.py, tests/test_core/test_pumpswap.py, README.md, CLAUDE.md, pyproject.toml, src/pumpfun_cli/__init__.py
Routes trades through the bonding curve, PumpSwap, LaunchLab, and CPMM based on lookup results and --force-amm. Token information and text output include venue, pool, reserve, and fee details. The project version changes to 0.3.0.

end
With --force-amm on a graduated LaunchLab coin, a CPMM trade can be sent but fail to confirm. The CLI then reports that no pool exists and hides the transaction signature. The user may retry and trade twice. Fix this before merging; the rest of the change looks sound.

Full details: Linked Issues check
Explanation
Issue #26 is the only active directly linked issue. Its coding requirement is that build_migrate_v2_instruction append two accounts after the 27 IDL accounts: the pool's boost vault authority (PDA, seeds ["boost_vault", pool]) and that authority's writable quote-mint token account. The summary shows instructions.py now derives the authority with derive_amm_boost_vault_authority(pool) (protocol/address.py) and appends the authority and its quote-token ATA as the final two accounts. Tests cover this: test_extras_instructions.py checks the appended accounts and compares the full account keys, including writable flags, against a recorded mainnet SOL-priced migration. test_instructions.py expects 29 accounts for migrate_v2. The acceptance criterion to run a migration on a real local validator is covered by tests/test_surfpool/test_extras.py::test_migrate_a_completed_curve, which migrates a completed curve and checks that the PumpSwap pool exists. Limit of evidence: the summary does not state explicitly that the quote-token ATA uses the quote mint's token program. The mainnet fixture covers only a SOL quote, which uses the standard token program. A non-SOL (Token-2022) quote migration is not shown to be tested. The core failure in #26 (missing two accounts) is addressed.
Full details: Description check
Explanation
The description covers the main changes: LaunchLab and CPMM trading, the migrate boost vault fix, bonding-curve sell capping, buy-over-curve messaging, and the version bump. It states verification methods and links issue #26. It does not fill the template's Summary heading format, the Layers touched section, the transaction construction or signing question, or a detailed Test Plan. These gaps are non-critical but the transaction construction question matters for this protocol-layer change.
Resolution
Add the template sections that are missing or incomplete: (1) Under "Layers touched", list commands/, core/, and protocol/ as they apply, or delete the lines that do not apply. (2) Answer "Does this affect transaction construction or signing?" with Yes, because the change adds swap instructions for LaunchLab and CPMM and changes the migrate instruction account list. Describe those changes and how correctness was checked, such as the account list tests and the IDL comparison. (3) Expand the Test Plan with the specific unit test files, the surfpool test cases, and the mainnet round trips that were run, including which venues were covered.
Full details: Out of Scope Changes check
Explanation
Issue #26 covers only the two missing migrate_v2 accounts. The PR includes large changes that do not implement #26 and are not needed for it: (1) new Raydium LaunchLab trading in core/launchlab.py, protocol/launchlab.py, and the buy, sell, and info routing in commands/trade.py and core/info.py; (2) new Raydium CPMM support in core/cpmm.py and protocol/cpmm.py, including graduated-coin routing and --force-amm CPMM fallback; (3) Token-2022 transfer-fee handling for LaunchLab; (4) bonding-curve sell capping via max_sell_within_real_reserves, curve_short, and tokens_kept in core/trade.py and protocol/curve.py; (5) the exceeds_curve error and remaining-token reporting for buys; (6) the version bump to 0.3.0 in pyproject.toml and __init__.py; and (7) README and CLAUDE.md documentation for these features. Their tests and fixtures (test_launchlab.py, test_cpmm.py, test_trade_cmd.py, test_trade.py, surfpool LaunchLab, CPMM, and trade tests) support those same features. The PR description also states Closes #26 while presenting these features as its main content. No linked issue covers them in the provided context.
Resolution
Split the unrelated work into separate pull requests, each linked to the issue that requests it: LaunchLab and CPMM trading, transfer-fee handling, bonding-curve sell capping, the exceeds_curve buy error, and the version bump with its docs. Keep in this PR only the migrate_v2 change: instructions.py, protocol/address.py (derive_amm_boost_vault_authority), the migrate test updates in test_extras_instructions.py and test_instructions.py, and the test_migrate_a_completed_curve surfpool test. Update the PR description to remove the unrelated items and keep Closes #26. If the author intends to ship these features together, link the issues they implement and confirm that each one is in scope.

Preserve CPMM confirmation failures in --force-amm routing.
If confirmation fails after a CPMM trade is sent, _route discards the signature-bearing cpmm_error and reports that no PumpSwap pool exists. The trade may have landed; a retry can execute it again.
Use a distinct exception for confirmation failures so both CPMM trades can return an error that routing preserves. Do not classify every RuntimeError from send_tx as post-send: the call also performs work before sending.

@smypmsa Thanks. I inspected #34. It preserves the signature for CPMM buys and sells on v3-next.
The fix is not yet on main. The new regression tests cover buys, but not sells. Please bring the fix to main and add sell coverage for CPMM and --force-amm output. I did not run the tests.
