Exceptions

exception eth.exceptions.BlockNotFound: Raised when the block with the given number/hash does not exist. This will happen, for example, if the transactions or uncles are not saved in the database.

exception eth.exceptions.CanonicalHeadNotFound: Raised when the chain has no canonical head.

exception eth.exceptions.CheckpointsMustBeCanonical: Raised when a persisted header attempts to de-canonicalize a checkpoint

exception eth.exceptions.ContractCreationCollision: Raised when there was an address collision during contract creation.

exception eth.exceptions.FullStack: Raised when the stack is full.

exception eth.exceptions.GapTrackingCorrupted: Raised when the tracking of chain gaps appears to be corrupted (e.g. overlapping gaps)

exception eth.exceptions.Halt: Raised when an opcode function halts vm execution.

exception eth.exceptions.HeaderNotFound: Raised when a header with the given number/hash does not exist.

exception eth.exceptions.IncorrectContractCreationAddress: Raised when the address provided by transaction does not match the calculated contract creation address.

exception eth.exceptions.InsufficientFunds: Raised when an account has insufficient funds to transfer the requested value.

exception eth.exceptions.InsufficientStack: Raised when the stack is empty.

exception eth.exceptions.InvalidInstruction: Raised when an opcode is invalid.

exception eth.exceptions.InvalidJumpDestination: Raised when the jump destination for a JUMPDEST operation is invalid.

exception eth.exceptions.OutOfBoundsRead: Raised when an attempt was made to read data beyond the boundaries of the buffer (such as with RETURNDATACOPY)

exception eth.exceptions.OutOfGas: Raised when a VM execution has run out of gas.

exception eth.exceptions.ParentNotFound: Raised when the parent of a given block does not exist.

exception eth.exceptions.PyEVMError: Base class for all py-evm errors.

exception eth.exceptions.ReceiptNotFound: Raised when the Receipt with the given receipt index does not exist.

exception eth.exceptions.ReservedBytesInCode: Raised when bytes for the code to be deployed are reserved for a particular reason.

exception eth.exceptions.Revert

Raised when the REVERT opcode occurred

burns_gas = False

erases_return_data = False

exception eth.exceptions.StackDepthLimit: Raised when the call stack has exceeded it’s maximum allowed depth.

exception eth.exceptions.StateRootNotFound

Raised when the requested state root is not present in our DB.

property missing_state_root: Hash32

exception eth.exceptions.TransactionNotFound: Raised when the transaction with the given hash or block index does not exist.

exception eth.exceptions.UnrecognizedTransactionType

Raised when an encoded transaction is using a first byte that is valid, but unrecognized. According to EIP 2718, the byte may be in the range [0, 0x7f]. As of the Berlin hard fork, all of those versions are undefined, except for 0x01 in EIP 2930.

property type_int: int

exception eth.exceptions.VMError

Base class for errors raised during VM execution.

burns_gas = True

erases_return_data = True

exception eth.exceptions.VMNotFound: Raised when no VM is available for the provided block number.

exception eth.exceptions.WriteProtection: Raised when an attempt to modify the state database is made while operating inside of a STATICCALL context.
