stx.fan

For fans of Stacks, and for that link you needed to find.

stx.fan is a curated entry point into the Stacks ecosystem and a home for practical, resilient tools: reliable fallbacks, replacement frontends, and new ways to use the network.

Start here

Stacks is a Bitcoin layer for smart contracts. It settles to Bitcoin, is secured by its own proof-of-transfer consensus, and lets BTC and STX holders earn by helping run the network.

Learn

The official documentation covers how the chain works, from block production to sBTC. stacks101.com is a gentler community-made introduction.

Get a wallet

Leather and Xverse are the two main self-custodial wallets. Asigna provides native multisig.

Explore the chain

The Hiro Explorer shows transactions, accounts, and contracts. STXER adds transaction analysis and simulation.

Stake

Lock STX, or pair BTC with STX, to support consensus and earn rewards. The staking section below covers what changed with PoX-5.

Build with Clarity

Clarity is the decidable smart contract language of Stacks. Start with the Clarity Book, the docs, and Hiro Platform.

Tools hosted on stx.fan

Independent, static, wallet-signed apps. Nothing to operate, no backend, keys stay in your wallet. This is the kind of tool stx.fan exists to host: fallbacks and replacement frontends the network can rely on.

flagship

Zero to Signing

One guided page that takes a signer operator from nothing to a registered, staked, signing signer. Prefilled where possible, post-conditions on every transaction, and the URL is the state: reload or share a link and the flow resumes.

toolset

Signer Sidekick

The eight-step toolset Zero to Signing grew out of: preflight, key helper, contract deploy, registration, staking, rewards, and management as separate single-purpose dapps. Still maintained, still useful when you want one step at a time.

More zero_to apps are planned. If a contract you rely on lost its frontend, open an issue.

Staking after PoX-5

On July 30, 2026, at Bitcoin block 960230, the Epoch 4.0 hard fork activated PoX-5, the first of the Satoshi Upgrades. It introduces Bitcoin staking: BTC held on Bitcoin L1 (or sBTC), paired with locked STX, earning self-custodial BTC yield. STX-only staking continues, and what older material calls stacking lives on under that name.

Read the primary sources

The Bitcoin Staking on Stacks whitepaper (PDF), the staking docs and what changed in PoX-5, and the pox-5 contract itself.

Participate

Bitcoin staking rolls out in phases, starting with the institutional Genesis Bond and expanding through selected pools. For STX-only staking today: Leather Earn, Xverse Pool, or liquid via StackingDAO. Track cycles at Stacking Tracker.

Documentation is in transition. The ecosystem is still updating docs and interfaces to Epoch 4.0 and PoX-5 terminology, so expect a mix of old and new wording for a while. The history page keeps the old terms and their current equivalents.

About and contribute

stx.fan is a community site. It links to what is valuable, hosts tools the network needs as reliable fallbacks or backups of existing alternatives, and keeps frontends alive for contracts whose original deployers no longer maintain one.

The site is a public repository: github.com/wmnonstx/stx-fan. Comment, open issues, or push changes. Older material lives on the history page.

No financial advice. Tools on this site construct transactions that your own wallet reviews and signs. Verify contract addresses and amounts before signing, here and everywhere else.
