Fiatsend Resolver SDK

Overview

The Fiatsend Resolver SDK allows developers to retrieve encrypted phone numbers linked to Fiatsend NFTs. Similar to how ENS resolves addresses, this SDK enables users to set and query a primary mobile number stored as NFT metadata.

Features

• Resolve Mobile Numbers: Retrieve encrypted phone numbers associated with Fiatsend NFTs.
• Set Primary Number: Users can set a primary NFT that resolves their phone number.
• ENS-Like Resolution: Works similarly to ENS by mapping wallet addresses to phone numbers.
• Supports Multiple NFTs: Users can own multiple NFTs but set only one as primary.

Installation

To install the Fiatsend Resolver SDK, run:

npm install @fiatsend/resolver

or with Yarn:

yarn add @fiatsend/resolver

Usage

Importing the Resolver

import { resolver } from "@fiatsend/resolver";

Initialize the Resolver

const provider = new ethers.providers.JsonRpcProvider("https://your_rpc_url");
const contractAddress = "0xYourNFTContractAddress";
const resolverInstance = new resolver(provider, contractAddress);

Get Encrypted Phone Number by Token ID

const tokenId = 1;
const phoneNumber = await resolverInstance.getEncryptedPhoneNumber(tokenId);
console.log("Encrypted Phone Number:", phoneNumber);

Get Primary Phone Number for a Wallet Address

const userAddress = "0xUserWalletAddress";
const primaryPhoneNumber =
  await resolverInstance.getPrimaryEncryptedPhoneNumber(userAddress);
console.log("Primary Encrypted Phone Number:", primaryPhoneNumber);

Set Primary NFT for a User

const signer = provider.getSigner();
await resolverInstance.setPrimaryToken(tokenId, signer);
console.log("Primary NFT set successfully");

Smart Contract Reference

Ensure the Fiatsend NFT contract implements the following functions:

• getEncryptedPhoneNumber(uint256 tokenId) view returns (string memory)
• getPrimaryEncryptedPhoneNumber(address user) view returns (string memory)
• setPrimaryToken(uint256 tokenId)
