- Replace compile-time `pumpfun-v2` feature flag with runtime
`TradeConfig::use_pumpfun_v2(bool)` for flexible V1/V2 switching
- Fix BUYBACK_FEE_RECIPIENTS pool: replace wrong addresses (was reusing
standard pool + FEE_CONFIG) with official buyback pool from
FEE_RECIPIENTS.md
- Fix legacy buy/buy_exact_sol_in ix data encoding: use 2-byte
Option<bool> (option tag + value) matching official Pump SDK, 26 bytes

- Add `SwapParams.use_pumpfun_v2` field and wire through TradingClient
buy/sell paths
- V2 instructions read `quote_mint` from `PumpFunParams` (not
BondingCurveAccount which lacks the field)
- Fix `fetch_bonding_curve_account` to use BorshDeserialize instead of
non-existent `decode_from_chain_account_data`
- Update all examples with `use_pumpfun_v2: false` field
- Update README with unified V1/V2 section showing both enabling methods
The `effective_pump_mint_token_program` helper was defaulting to
TOKEN_PROGRAM_2022 when `token_program` was Pubkey::default(), causing
Anchor error 0xbbf (account owned by wrong program) for all legacy
PumpFun coins whose ATAs are owned by the original Token Program.
Fall back to TOKEN_PROGRAM (legacy) when no explicit token program is
provided. Token-2022 must be set explicitly for create_v2 coins.

- Pass token_a/token_b program based on swap direction (is_a_in) when

- Always derive bonding curve and associated bonding vault from mint (avoids stale cached PDAs / wrong pool).
- Use non-default fee_recipient from parser/stream as account #2 without extra authorization filtering (addresses Pump 6000 NotAuthorized when event fee was rejected).
- Rework resolve_creator_vault_for_ix: default-creator cases, phantom default PDA, fee-sharing vault; add unit tests.
- PumpFunParams: respect explicit mayhem_mode from events; fallback creator_vault via get_creator_vault_pda when resolve returns None.
- Remove unused lazy_static tip-cache stub and lazy_static dependency.
Made-with: Cursor
- Add get_fee_sharing_config_pda per @pump-fun/pump-sdk (sharing-config + mint under pump-fees)
- resolve_creator_vault_for_ix now takes mint: accept gRPC creator_vault when it matches either
PDA(creator) or PDA(fee_sharing_config(mint)) for migrated / fee-sharing bonding curves
- Mayhem uses the same Pump buy/sell account layout (IDL); Token-2022 + fee pool differ, not creator_vault seeds
Made-with: Cursor
- Add resolve_creator_vault_for_ix: use gRPC creator_vault only when it matches
PDA(['creator-vault', bonding_curve.creator]); on mismatch use derived PDA to
avoid ConstraintSeeds (2006) from stale/wrong stream vaults
- pump_fun_fee_recipient_meta: only use event fee_recipient if authorized for
is_mayhem_mode (avoids 6000 NotAuthorized when standard AMM fee is used on
Mayhem coins)
- Align PumpFunParams::from_trade/from_dev_trade cached creator_vault with the
same resolution logic
Made-with: Cursor
- Use protocol_params.creator_vault for buy/sell when non-default to avoid
ConstraintSeeds (2006) when gRPC/event creator drifts from on-chain bonding curve
- Preserve event creator_vault in PumpFunParams::from_trade/from_dev_trade instead
of always overwriting with PDA(creator)
- Fee recipient: prefer gRPC fee_recipient; else random from CURRENT_FEE_RECIPIENTS
pool (standard) or MAYHEM pool, matching @pump-fun/pump-sdk fees.ts
- Add cold-path helpers: extend_bonding_curve_account_instruction, PUMP_BONDING_CURVE_MIN_DATA_LEN
Made-with: Cursor
- PumpFunParams::from_trade/from_dev_trade: add mayhem_mode Option; infer Mayhem
via is_mayhem_fee_recipient when None (fixes fee recipient / NotAuthorized 6000
when AMM protocol fee pubkey is used).
- Add is_mayhem_fee_recipient and is_amm_fee_recipient helpers in pumpfun utils.
- Bump solana-* crates to 3.1.12; align tonic/prost; use solana-message for
AddressLookupTableAccount; add solana-system-interface 3.0.

主要解决问题：
当 wait_tx_confirmed 参数为 false 时，SUBMIT_TIMEOUT_SECS 等待改为2秒，要么全部提交完成返回，要么不等待提交未返回的交易，方便快速创建交易订单。
#Let the SDK print submit_timing data (SwqosType and submission time) and return it to the buy and sell methods.
Main problems solved:
When the wait_tx_confirmed parameter is false, the SUBMIT_TIMEOUT_SECS wait is changed to 2 seconds. Either all submissions are completed and returned, or the unreturned transactions are not waited for submission, which facilitates the rapid creation of transaction orders.
When using find_by_mint() followed by from_pool_address_by_rpc(), the pool
account is fetched twice via getAccount — once in find_by_mint (which returns
the decoded Pool) and again in from_pool_address_by_rpc.
from_pool_data() accepts a pre-decoded Pool reference and only fetches the
2 token balance RPC calls, saving 1 getAccount per trade.
from_pool_address_by_rpc() now delegates to from_pool_data() internally,
so existing callers are unaffected.

- All 18 examples pass cargo check --workspace
Made-with: Cursor
In v3.5.0, confirmation was split out of execute_parallel into
poll_transaction_confirmation, but it only polled sig[0]. When
multi-channel submit is used, each channel produces a different
signature and only one lands on-chain. If the landed sig is not
sig[0], the poll times out after 15s and reports failure despite
a successful on-chain transaction.
Add poll_any_transaction_confirmation() that passes all signatures
to get_signature_statuses in a single RPC call per poll, returning
the first one that confirms. The executor now uses this instead of
polling a single signature.

When using multiple SWQOS channels with durable nonce, if one channel's
transaction lands on-chain but fails (e.g., ExceededSlippage), the nonce
is consumed and other channels cannot succeed.
Previously, the SDK would wait for all channels to timeout (~15s) before
returning, and would often return a generic "timeout" error instead of
the actual on-chain error.
This fix:
- Adds `landed_on_chain` field to TaskResult to track if tx landed
- Adds `is_landed_error()` to detect on-chain failures vs timeouts
- Adds `landed_failed_flag` to ResultCollector for early exit signaling
- Returns immediately with the actual error when a tx lands but fails
This makes behavior consistent with the success case - both return
immediately once the nonce is consumed.
Benefits:
1. Get the actual error (e.g., ExceededSlippage) instead of timeout
2. Return in ~1s instead of ~15s
3. Enable faster retry logic for callers
