Error reference

Each program returns Anchor errors with the messages below, exactly as written in the source. The number is the error's position in its enum, offset by Anchor's 6000 base.

floor_venue

Code	Name	Message	What to do
6000	NotAuthority	Signer is not the venue authority	Admin call from the wrong key.
6001	ZeroKey	Key must not be zero	Pass a real authority or fee recipient.
6002	FeeTooHigh	Fee above 10% or venue share above 100%	`fee_bps <= 1000`, `venue_share_bps <= 10000`.
6003	NoChange	Nothing to change	The flag already has that value.
6004	EmptySymbol	Symbol must not be empty	First byte of the symbol must be set.
6005	StockNotToken2022	Stock mint must be a Token-2022 mint	Qualifying shares are Token-2022.
6006	NoIssuerGate	Stock mint has neither a transfer hook nor frozen-by-default accounts with a freeze authority (no issuer allowlist)	The order needs issuer-controlled access; FWDI and GLXY pass through frozen-by-default accounts that Superstate thaws.
6007	SymbolNotListed	Symbol is not listed in the caps program	Call `floor_caps::list_symbol` first.
6008	DecimalsMismatch	Caps listing decimals differ from the mint	Relist with the mint's decimals.
6009	NotAdmitted	Wallet is not an admitted participant	Ask the venue to admit the wallet.
6010	VenuePaused	Venue is paused	Wait for `VenuePaused { paused: false }`.
6011	PoolPaused	Pool is paused	Wait for `PoolPaused { paused: false }`.
6012	Halted	Symbol is halted on its primary listing market	Wait for the resume event.
6013	NoticeNotOpen	Issuer notice period not over, or an objection is on file	Third-party token before day 30, or barred.
6014	ZeroAmount	Amount must be positive
6015	DepositTooSmall	Deposit too small for the pool	Raise the deposit so it mints at least one LP unit.
6016	Slippage	Output below the minimum asked	Re-quote and lower `min_out`, or raise `min_lp` tolerance.
6017	BadQuote	Quote impossible: empty reserve, zero output or pool would be drained	The pool has no liquidity on one side, or the trade is too large.
6018	Insolvent	Vault holds less than the venue fees owed	Should not happen; report it.
6019	Overflow	Arithmetic overflow

6022	Throttled	Near the cap, a single fill may be at most 1% of the cap
6023	Overflow	Arithmetic overflow

A swap that fails with a caps error surfaces it through the CPI; the transaction log names floor_caps and the message above.

Issuer gate failures

A transfer into a token account the issuer has not thawed (FWDI and GLXY accounts are frozen by default) fails inside Token-2022 with its frozen-account error, before any venue error. In the local harness the stand-in hook refuses with a plain Custom error; on mainnet the message is the issuer's.
