Exchanges use it for deposit tagging, dapps use it for on-chain messages and protocol metadata, and some people just use it as a free public notes field attached to a payment. I wanted a tool that treats memos as first-class: paste an address, and watch every note it's ever attached to a transaction stream in, already decoded, searchable, and filterable by date — all without sending a single byte to a server I control, because there isn't one!</p> <h2> Demo </h2> <p>Run it locally in under a minute:<br> <a href="https://xrplmemoscanner.netlify.app/" rel="noopener noreferrer">https://xrplmemoscanner.netlify.app/</a></p> <h2> Code </h2> <p>Visit the open source repo:<br> <a href="https://github.com/Ghostrayu/xrplmemoscanner" rel="noopener noreferrer">https://github.com/Ghostrayu/xrplmemoscanner</a></p> <h2> How I Built It </h2> <p>It's a TypeScript single-page app, using the official<br> <a href="https://www.npmjs.com/package/xrpl" rel="noopener noreferrer"><code>xrpl.js</code></a> client library — and nothing else on the backend, because there is no backend. Everything <code>account_tx</code> returns is public ledger data; any node will answer the same query for anyone, so running it entirely client-side means no server to host, no API keys to manage, and no data ever leaves the visitor's browser!</p> <p><strong>The passion part: Xahau support.</strong> Xahau is a rippled-derived sidechain (same <code>account_tx</code> RPC shape, same address format, its own native asset and public nodes) built around the Hooks amendment — programmable smart-contract-like logic directly on a ledger descended from XRPL. I wanted this tool to work there too, so the network became a config object (<code>lib/networks.ts</code>: endpoints + explorer URL per network) instead of a hardcoded constant, with a toggle next to the address field. Because Xahau is protocol-compatible with XRPL at the RPC level, the entire scan/decode/reconnect pipeline needed zero changes — only the endpoint list and explorer link differ per network. Your last-picked network persists across reloads via <code>localStorage</code>.</p> <p>For Dev Inquiries, please email: <a href="mailto:ghostrayu@protonmail.com">ghostrayu@protonmail.com</a></p> devchallenge weekendchallenge xrpl webdev
