# xroot.dev

> xroot.dev publishes on-chain research and builds the tools it leads to — wallet and token checks on Solana and Robinhood Chain, and the operations to act on what they find. Nothing to connect to check, nothing to sign until you decide.

Research and tools for what is actually on-chain. The research is published here; the tools built from it run on https://app.xroot.dev. Checking reads public chain data — there is no wallet to connect and nothing to sign until you decide to act on a finding. Your own wallet signs every operation and receives whatever comes back; nothing is ever held on your behalf.

## Research

- [How to Claim SOL From Empty Solana Token Accounts](https://xroot.dev/blog/claim-sol): Each empty Solana token account holds a refundable ~0.002 SOL deposit. What 'claim SOL' means, why the SOL is there, how the 2026 rent cut changes it, and how to reclaim it.
- [Permissioned Tokens on Solana: How Token ACL Works — and How to Tell It From a Honeypot](https://xroot.dev/blog/solana-permissioned-tokens-token-acl): Solana's sRFC-37 Token ACL standard makes regulated tokens start frozen and unlock through a published gate — the exact on-chain shape of a honeypot scam. How the standard works, what's really live on mainnet, and the structural check that tells them apart.
- [Solana's 4,096-Byte Transactions: What v1 Breaks and How to Fix It](https://xroot.dev/blog/solana-transaction-v1): SIMD-0296 raises Solana transaction size from 1,232 to 4,096 bytes via the new v1 format. What breaks for RPC readers, indexers, and senders — error -32015, zero default limits, new priority-fee units — and the exact fix for each.
- [Robinhood Chain: Three Things the Docs Don't Say](https://xroot.dev/blog/robinhood-chain-read-directly): Reading Robinhood Chain with eth_call turns up an active transaction filterer, an undocumented token blocklist, and an identity check that actually holds.
- [Solana's 90% Rent Cut: The Economics of SIMD-0437](https://xroot.dev/blog/solana-rent-cut-simd-0437): SIMD-0437 cuts Solana rent 90% in five feature-gated steps — but accounts funded at the old rate keep every lamport. What the cut changes for reclaims, airdrops, compression, and mints.
- [Zero-Latency DeFi: Parsing Raw Solana AMM Accounts in Rust](https://xroot.dev/blog/zero-latency-defi-parsing): Bypass SDK abstraction entirely. Reverse-engineer Solana AMM account layouts, strip the Anchor discriminator, and deserialize raw pool state with zero-copy bytemuck casting at microsecond speed.
- [Zero-Data-Loss Analytics: Scaling NATS and ClickHouse for Web3 (Part 3)](https://xroot.dev/blog/solana-pipeline-part-3): NATS JetStream persistence, a production ClickHouse MergeTree schema for billions of swap rows, batch ingestion with tokio::select!, and a decoupled Axum WebSocket fanout layer.
- [Ingesting the Solana Firehose: High-Throughput Decoding with Rust (Part 2)](https://xroot.dev/blog/solana-pipeline-part-2): Connection resilience with exponential backoff, zero-copy transaction decoding with the carbon crate, and bounded mpsc channels for backpressure-safe NATS publishing.
- [Architecting a Solana Data Pipeline: Economics & System Design (Part 1)](https://xroot.dev/blog/solana-pipeline-part-1): Why REST polling fails at Solana scale, the RPC math for the Helius Professional Plan, and designing a zero-latency VPC topology for a real-time swap indexer.

## Tools

- [Solana wallet check](https://app.xroot.dev/unclaimed): Paste any Solana address and run eleven read-only checks — unclaimed fees, rent locked in empty accounts, the surplus left by the rent cut, dead liquidity positions, abandoned programs, wrapped SOL, and standing approvals. No wallet connection.
- [Token audit](https://app.xroot.dev/token-audit): Check any Solana or Robinhood Chain token for rug and honeypot risks — who controls it, hidden taxes and traps, and holder concentration.
- [Solana tools](https://app.xroot.dev/solana): Every operation available on Solana — reclaim SOL from empty accounts, take back the rent surplus, unwrap wrapped SOL, revoke authorities, create and manage tokens, liquidity and fees.
- [Robinhood Chain tools](https://app.xroot.dev/robinhood): Rug check, wallet check, token approvals, and a live list of new and trending tokens on chain 4663.
- [Solana upgrade timeline](https://app.xroot.dev/upgrades): What changes next on Solana and when, read from the chain rather than from announcements.

## For AI agents and developers

- [Markdown for any page](https://xroot.dev/): Send `Accept: text/markdown` to any URL on this site and the markdown version is returned instead of HTML, with `x-markdown-tokens` and `x-original-tokens` headers reporting what that saved. A page with no markdown variant answers in HTML rather than failing.
- [Content policy](https://xroot.dev/robots.txt): `Content-Signal: ai-train=no, search=yes, ai-input=yes`. Quoting this content in an answer is expected; training on it is not.
- [Tools index for models](https://app.xroot.dev/llms.txt): The same treatment for the application — every service with a URL and a one-line description.
- [MCP server card](https://app.xroot.dev/.well-known/mcp/server-card.json): The tools are callable over MCP. Agents bring their own funded wallet, receive unsigned transactions, sign locally and submit.
- [Agent skill](https://app.xroot.dev/.well-known/agent-skills/xroot-token-ops/SKILL.md): How to drive the token operations end to end.
- [Feeds](https://xroot.dev/feed.xml): RSS, [Atom](https://xroot.dev/atom.xml) and [JSON Feed](https://xroot.dev/feed.json), all full-content.
