| 7001 | InvalidInputsMint | The mint account input is invalid. |
| 7002 | InvalidVersion | The on-chain state has a version number higher than expected or zero (uninitialized) when it shouldn't be. |
| 7003 | FeeTokenMismatch | The fee token doesn't match the minted token used for the transfer. |
| 7005 | ReachedMaxSequenceNumber | The sequence number cannot be incremented further (u64 overflow). This is very unlikely. |
| 7006 | InvalidInputsTokenIndices | The sub-slice token index calculations are invalid, or token_indexes.len() doesn't match the number of tokens. |
| 7007 | InvalidInputsPoolAccounts | The passed "pool sub-slice" accounts do not match the expected PDAs for the token pool's configuration. |
| 7008 | InvalidInputsTokenAccounts | The user token or pool token account is invalid (wrong ATAs or minted by a different token). |
| 7009 | InvalidInputsConfigAccounts | The required config PDAs do not match (e.g., the "billing" config or the "pool chain config" for that chain). |
| 7010 | InvalidInputsTokenAdminRegistryAccounts | The token_admin_registry passed does not match the expected PDA. |
| 7011 | InvalidInputsLookupTableAccounts | The Address Lookup Table (ALT) provided is invalid or does not match what the token_admin_registry expects. |
| 7012 | InvalidInputsLookupTableAccountWritable | One or more accounts in the lookup table are incorrectly marked as writable / non-writable. |
| 7013 | InvalidInputsTokenAmount | An attempt was made to send a token amount of zero. |
| 7015 | InvalidInputsAtaAddress | The associated token account address does not match what was expected. |
| 7016 | InvalidInputsAtaWritable | If the user's fee-token ATA is not flagged as writable, we need to debit it. |
| 7018 | InsufficientLamports | Users paying with native SOL have insufficient lamports to cover the required fee transfer. |
| 7019 | InsufficientFunds | Insufficient funds in a token account. |
| 7020 | SourceTokenDataTooLarge | The returned "dest_pool_data" from lockOrBurnOut is larger than the allowed CCIP_LOCK_OR_BURN_V1_RET_BYTES, or larger than the dest_bytes_overhead. |
| 7023 | SenderNotAllowed | The sender (caller) is not in the allowed_senders list for that destination chain, and the allow-list is enabled. |
