Lookup Address

Coming Soon - Email, Twitter, etc

Currently the Node identity service only handles phone numbers. Node is actively working on supporting email and social media handles

An address can be looked up through the lookup method exposed from the NodeIdentityKit.

Lookup

Looks up the address associated with the given phone number.

Parameters

Name	Type	Default	Description
identifier	string		Phone number to look up
identifierType	IdentityType	"phone"	Type of identifier to look up. Currently, only "phone" is supported.

Returns

Name	Type	Description
address	string	Address associated with the phone number
attestor	string	Address of the attestor that attested the association between the phone number and address
issuedOn	number	Unix timestamp of when the attestation was issued

Handling Multiple Attestations

If there are multiple attestations for the given phone number, they are sorted based on the mergeStrategy specified in the constructor. If mergeStrategy is set to "latest", the most recent attestation will be used. If mergeStrategy is set to "earliest", the earliest attestation will be used.

If there are multiple attestations from different attestors, the _trustFactor object is used to determine which attestation to use. Attestations from trusted attestors (as specified in the trustedAttestors array passed to the constructor) are given a higher priority, with the priority being determined by the index of the attestor in the trustedAttestors array. If an attestation is from Node, it is given a priority equal to the length of the trustedAttestors array (i.e. the lowest priority).

Example

import { NodeIdentityKit, Attestor } from "@node-fi/identity";
import { getApiKey, TokenAmount, Wallet } from "@node-fi/sdk-core";

const kit = new NodeIdentityKit(
  getApiKey(),
  Attestor.fetchByNames(["node", "valora", "kaala"])
);

const sendToPhoneNumber = async (
  from: Wallet,
  amount: TokenAmount,
  recipientPhoneNumber: string
) => {
  const { address } = await kit.lookup(recipientPhoneNumber);
  return from.send(amount, address);
};
