Expand description

An invalid transaction validity.

Variants§

§

Call

The call of the transaction is not expected.

§

Payment

General error to do with the inability to pay some fees (e.g. account balance too low).

§

Future

General error to do with the transaction not yet being valid (e.g. nonce too high).

§

Stale

General error to do with the transaction being outdated (e.g. nonce too low).

§

BadProof

General error to do with the transaction’s proofs (e.g. signature).

Possible causes

When using a signed extension that provides additional data for signing, it is required that the signing and the verifying side use the same additional data. Additional data will only be used to generate the signature, but will not be part of the transaction itself. As the verifying side does not know which additional data was used while signing it will only be able to assume a bad signature and cannot express a more meaningful error.

§

AncientBirthBlock

The transaction birth block is ancient.

Possible causes

For FRAME-based runtimes this would be caused by `current block number

  • Era::birth block number > BlockHashCount. (e.g. in Polkadot BlockHashCount` = 2400, so a transaction with birth block number 1337 would be valid up until block number 1337 + 2400, after which point the transaction would be considered to have an ancient birth block.)
§

ExhaustsResources

The transaction would exhaust the resources of current block.

The transaction might be valid, but there are not enough resources left in the current block.

§

Custom(u8)

Any other custom invalid validity that is not covered by this enum.

§

BadMandatory

An extrinsic with a Mandatory dispatch resulted in Error. This is indicative of either a malicious validator or a buggy provide_inherent. In any case, it can result in dangerously overweight blocks and therefore if found, invalidates the block.

§

MandatoryValidation

An extrinsic with a mandatory dispatch tried to be validated. This is invalid; only inherent extrinsics are allowed to have mandatory dispatches.

§

BadSigner

The sending address is disabled or known to be invalid.
