Constructors

constructor

+ new Account(nonce: BN‹›, balance: BN‹›, stateRoot: Buffer‹›, codeHash: Buffer‹›): Account

Defined in account.ts:61

This constructor assigns and validates the values. Use the static factory methods to assist in creating an Account from varying data types.

Parameters:

Name	Type	Default
nonce	BN‹›	new BN(0)
balance	BN‹›	new BN(0)
stateRoot	Buffer‹›	KECCAK256_RLP
codeHash	Buffer‹›	KECCAK256_NULL

Returns: Account

Properties

balance

• balance: BN

Defined in account.ts:27

---

codeHash

• codeHash: Buffer

Defined in account.ts:29

---

nonce

• nonce: BN

Defined in account.ts:26

---

stateRoot

• stateRoot: Buffer

Defined in account.ts:28

Methods

isContract

▸ isContract(): boolean

Defined in account.ts:106

Returns a Boolean determining if the account is a contract.

Returns: boolean

---

isEmpty

▸ isEmpty(): boolean

Defined in account.ts:115

Returns a Boolean determining if the account is empty. For more details about account emptiness see EIP-161. Note: The stateRoot is also checked to be empty since in Frontier it was possible to create a contract with no code where nonce remained 0 but some values were written to storage in the constructor (thus stateRoot is not KECCAK256_RLP).

Returns: boolean

---

serialize

▸ serialize(): Buffer

Defined in account.ts:99

Returns the RLP serialization of the account as a Buffer.

Returns: Buffer

---

Static fromAccountData

▸ fromAccountData(accountData: AccountData): Account‹›

Defined in account.ts:31

Parameters:

Name	Type
accountData	AccountData

Returns: Account‹›

---

Static fromRlpSerializedAccount

▸ fromRlpSerializedAccount(serialized: Buffer): Account‹›

Defined in account.ts:42

Parameters:

Name	Type
serialized	Buffer

Returns: Account‹›

---

Static fromValuesArray

▸ fromValuesArray(values: Buffer[]): Account‹›

Defined in account.ts:52

Parameters:

Name	Type
values	Buffer[]

Returns: Account‹›
