Iban

Converts Ethereum addresses to IBAN or BBAN addresses and vice versa. For using Iban package, first install Web3 package using: npm i web3 or yarn add web3 based on your package manager, after that ENS features can be used.


import { Web3 } from 'web3';
 const web3 = new Web3('https://mainnet.infura.io/v3/<YOURPROJID>');

 const iban = new web3.eth.Iban("XE81ETHXREGGAVOFYORK");
 console.log(iban.checksum());

For using individual package install web3-eth-iban packages using: npm i web3-eth-iban or yarn add web3-eth-iban.

import {Iban} from 'web3-eth-iban';

 const iban = new Iban("XE81ETHXREGGAVOFYORK");
 console.log(iban.checksum());

Constructors

publicconstructor

  • new Iban(iban: string): Iban

  • Construct a direct or indirect IBAN that has conversion methods and validity checks. If the provided string was not of either the length of a direct IBAN (34 or 35), nor the length of an indirect IBAN (20), an Error will be thrown ('Invalid IBAN was provided').

    @example
    const iban = new web3.eth.Iban("XE7338O073KYGTWWZN0F2WZ0R8PX5ZPPZS");
    > Iban { _iban: 'XE7338O073KYGTWWZN0F2WZ0R8PX5ZPPZS' }

    Parameters

    • iban: string

      a Direct or an Indirect IBAN

    Returns Iban

    • Iban instance

Methods

publicchecksum

  • checksum(): string

  • Returns the IBAN checksum of the early provided IBAN

    @example
    const iban = new web3.eth.Iban("XE81ETHXREGGAVOFYORK");
    iban.checksum();
    > "81"

    Returns string

publicclient

  • client(): string

  • Should be called to get client identifier within institution

    @example
    const iban = new web3.eth.Iban("XE81ETHXREGGAVOFYORK");
    iban.client();
    > 'GAVOFYORK'

    Returns string

    the client of the IBAN instance.

publicinstitution

  • institution(): string

  • Returns institution identifier from the early provided IBAN

    @example
    const iban = new web3.eth.Iban("XE81ETHXREGGAVOFYORK");
    iban.institution();
    > 'XREG'

    Returns string

publicisDirect

  • isDirect(): boolean

  • An instance method that checks if iban number is Direct. It actually check the length of the provided variable and, only if it is 34 or 35, it returns true. Note: this is also available as a static method.

    @example
    const iban = new web3.eth.Iban("XE81ETHXREGGAVOFYORK");
    iban.isDirect();
    > false

    Returns boolean

    • true if the provided iban is a Direct IBAN, and false otherwise.

publicisIndirect

  • isIndirect(): boolean

  • check if iban number if indirect It actually check the length of the provided variable and, only if it is 20, it returns true. Note: this is also available as a static method.

    @example
    const iban = new web3.eth.Iban("XE81ETHXREGGAVOFYORK");
    iban.isIndirect();
    > true

    Returns boolean

    • true if the provided iban is an Indirect IBAN, and false otherwise.

publicisValid

  • isValid(): boolean

  • Should be called to check if the early provided IBAN is correct. Note: this is also available as a static method.

    @example
    const iban = new web3.eth.Iban("XE81ETHXREGGAVOFYORK");
    iban.isValid();
    > true

    const iban = new web3.eth.Iban("XE82ETHXREGGAVOFYORK");
    iban.isValid();
    > false // because the checksum is incorrect

    Returns boolean

publictoAddress

  • toAddress(): string

  • This method should be used to create the equivalent ethereum address for the early provided Direct IBAN address. If the provided string was not a direct IBAN (has the length of 34 or 35), an Error will be thrown: ('Iban is indirect and cannot be converted. Must be length of 34 or 35'). Note: this is also available as a static method.

    @example
    const iban = new web3.eth.Iban("XE7338O073KYGTWWZN0F2WZ0R8PX5ZPPZS");

    const iban = new web3.eth.Iban('XE7338O073KYGTWWZN0F2WZ0R8PX5ZPPZS');
    iban.toString();
    > 'XE7338O073KYGTWWZN0F2WZ0R8PX5ZPPZS'
