sns-resolution-snap

This repo includes the npm package to install as a snap on MetaMask to resolve SNS - Sonic Name Service.

Overview

The Sonic Name Service (SNS) is a naming system for the Sonic chain (ID: 146) that allows users to register human-readable names (e.g., name.s) that resolve to Ethereum addresses. SNS is implemented as an ERC721 NFT, with each name represented by a unique tokenId.

This MetaMask Snap enables name resolution for SNS names directly within MetaMask, allowing users to:

• Type .s domains directly into MetaMask's address field
• Have the addresses automatically resolved to the correct Ethereum address
• Use SNS names for sending transactions and interacting with dApps

Features

• Resolves .s domain names to Ethereum addresses
• Performs reverse lookup to get SNS names from addresses
• Works on the Sonic chain (ID: 146)
• Seamlessly integrates with MetaMask's interface
• Provides additional RPC methods for dApps to interact with

RPC Methods

The snap exposes the following RPC methods for dApps to use:

1. reverseLookup - Get the SNS name for a given address

   const name = await ethereum.request({
     method: 'wallet_invokeSnap',
     params: {
       snapId: 'npm:sonic_resolver',
       request: {
         method: 'reverseLookup',
         params: {
           address: '0x123...'
         }
       }
     }
   });

2. getTokenIdForName - Get the tokenId for a given SNS name

   const result = await ethereum.request({
     method: 'wallet_invokeSnap',
     params: {
       snapId: 'npm:sonic_resolver',
       request: {
         method: 'getTokenIdForName',
         params: {
           name: 'example.s'
         }
       }
     }
   });
   console.log(result.tokenId);

3. getNameForTokenId - Get the SNS name for a given tokenId

   const result = await ethereum.request({
     method: 'wallet_invokeSnap',
     params: {
       snapId: 'npm:sonic_resolver',
       request: {
         method: 'getNameForTokenId',
         params: {
           tokenId: '123456'
         }
       }
     }
   });
   console.log(result.name);
