What Is STX? Understanding the Token Behind the Stacks Network

STX is the native token of Stacks, the leading Bitcoin layer by BTC deployed. It is the native asset powering the rails that are growing the Bitcoin economy, both literally through Bitcoin yield as staking capacity, and as the underlying fuel for every transaction, financial activity, and agent action on the network.

If you've already read our guide to Stacks, you know what the network does. This piece is about the asset that makes it all work.

What STX Does

STX serves three core functions within the Stacks network.

First, STX is the gas token for the Stacks network. Every transaction on Stacks, whether it's a trade on Bitflow, a loan on Zest, or an AI agent executing a decision through AIBTC, requires STX to process. As more activity flows through the network, more STX gets consumed as fees, creating a direct link between ecosystem growth and demand for the token. The more Bitcoin-native finance matures on Stacks, the more essential STX becomes to the economy running on it.

Secondly, STX is how Bitcoin yield gets generated. Through Stacking (Stacks' version of staking), users lock their STX to help secure the network and earn Bitcoin in return. This yield comes from Stacks miners spending actual BTC to mine blocks and earn the STX used by users and agents on economic activity. The Bitcoin they spend flows to Stackers as native Bitcoin yield. This creates a direct, ongoing economic loop between Bitcoin and STX. Dual Stacking, a Bitcoin staking pilot product that launched in late 2025, takes this further by allowing users to lock both STX and BTC simultaneously for enhanced Bitcoin yield, with over $100M in capital already participating.

Third, core contributors are planning for STX to become Bitcoin staking capacity. An upcoming self-custodial Bitcoin staking product is being researched and developed that will allow BTC holders to earn yield without giving up custody of their Bitcoin. In this model, STX exposure optionally increases the yield a BTC holder can earn. This positions STX as a direct lever for growing your Bitcoin.

Early Investors of STX

Investors of STX during its initial offerings include Union Square Ventures, Harvard Management Company, Y Combinator, Lux Capital, Digital Currency Group, Winklevoss Capital, Blockchain Capital, Foundation Capital, Hashkey Group, Fenbushi Capital, and SV Angel.

Early individual investors are Naval Ravikant, Kal Vepuri, Shana Fisher, Kevin Rose, Qasar Younis, Michael Arrington, with thousands of other individual investors taking part in the Reg A+ SEC-qualified offering in 2019.

Regulatory and Institutional Credibility

STX has one of the strongest regulatory track records in crypto. In July 2019, STX became the first-ever cryptocurrency to receive SEC qualification under Regulation A+, raising $28M in an offering open to both accredited and non-accredited investors in the United States. No other token had achieved this before, and it set a precedent for how blockchain projects could work within US securities law.

Since then, institutional infrastructure around STX has continued to build. The Grayscale Stacks Trust (ticker: STCK), which launched as a private placement in May 2024 and went public on OTCQB in October 2025, is the first publicly quoted US investment product offering direct exposure to STX. For investors in Europe, the 21Shares Stacks Stacking ETP (ASTX) has been live since April 2023, offering a 100% physically-backed, regulated product that automatically compounds stacking rewards. It trades on BX Swiss, Euronext Amsterdam, and Euronext Paris.

Beyond investment products, the broader Stacks ecosystem has secured integrations with Grade-A institutional infrastructure providers like BitGo and Fireblocks for custody. STX is integrated in a wide network of infrastructure providers that institutional capital can use today.

Where to Get STX

STX is one of the most widely accessible tokens in crypto. It is listed on over 59 exchanges globally, including Binance, Coinbase, Kraken, OKX, Upbit, KuCoin, and Bybit, across more than 100 trading pairs. Availability varies by region, so check your local exchange for more information and any applicable restrictions.

For investors who prefer regulated, traditional-finance vehicles, the Grayscale Stacks Trust (STCK) is available through standard US brokerage accounts, and the 21Shares ETP (ASTX) is accessible through European brokerages.

STX Timeline

The Stacks project was founded in 2017, with its mainnet launching in 2018 and the SEC-qualified token offering following in 2019. That gives STX over seven years of continuous development, making it one of the longest-running initiatives in crypto.

During that time, the network has shipped major technical milestones including Bitcoin finality, fast blocks, sBTC, Dual Stacking, and numerous upgrades unlocking new uses cases for a Bitcoin-native digital economy. The ecosystem has built a functioning DeFi ecosystem, integrated with tier-1 institutional infrastructure, and became the #5 fastest-growing developer community according to Electric Capital. The project has also established a long-term governance and treasury structure through the Stacks Endowment.

STX is the asset at the center of a Bitcoin economy using Stacks as the rails to operate on. As the Bitcoin economy on Stacks grows, from DeFi protocols and lending markets to autonomous AI agents and eventually yield-bearing institutional products, STX fuels every economic activity for BTC, and is the asset that generates Bitcoin yield for its holders.
