suix_resolveNameServiceAddress{deprecated} - Sui

Example code for the suix_queryTransactionBlocks JSON-RPC method. Complete guide on how to use suix_queryTransactionBlocks JSON-RPC in GetBlock Web3 documentation.

This method resolves a SuiNS (Sui Name Service) name to its corresponding SUI address. SuiNS provides human-readable names like example.sui that map to SUI addresses, similar to ENS on Ethereum. This method enables wallet applications and dApps to accept user-friendly names instead of hex addresses.

This method is deprecated

Parameters

Parameter	Type	Required	Description
name	string	Yes	The SuiNS name to resolve (e.g., "example.sui")

Request Example

cURL

curl -X POST https://go.getblock.io/<ACCESS-TOKEN>/ \

-d '{
  "jsonrpc": "2.0",
  "id": "getblock.io",
  "method": "suix_resolveNameServiceAddress",
  "params": ["example.sui"]
}'

JavaScript (Axios)

example.js

const axios = require('axios');

const payload = {
  jsonrpc: '2.0',
  id: 'getblock.io',
  method: 'suix_resolveNameServiceAddress',
  params: ['example.sui']
};

axios.post('https://go.getblock.io/<ACCESS-TOKEN>/', payload)
.then(response => console.log(response.data));

Python

example.py

import requests

payload = {
    "jsonrpc": "2.0",
    "id": "getblock.io",
    "method": "suix_resolveNameServiceAddress",
    "params": ["example.sui"]
}

response = requests.post("https://go.getblock.io/<ACCESS-TOKEN>/", json=payload)
print(response.json())

Rust

example.rs

use reqwest::Client;
use serde_json::json;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = Client::new();
    let payload = json!({
        "jsonrpc": "2.0",
        "id": "getblock.io",
        "method": "suix_resolveNameServiceAddress",
        "params": ["example.sui"]
    });
    let response = client.post("https://go.getblock.io/<ACCESS-TOKEN>/")
        .json(&payload).send().await?;
    println!("{}", response.text().await?);
    Ok(())
}
