Volume Bubbles Chart (1h)
Each 1-hour candle's volume is signed by its direction (up candles count as net buying, down candles as net selling) and drawn as a bubble at the closing price, green for buying and red for selling. Bubble size and colour intensity show how strong that flow is compared with the last 300 candles: the strongest 30% get full bubbles with their USD value, the rest stay as small dots. Unusually large bubbles flag aggressive buying or selling worth a closer look, often near breakouts, reversals or key levels.Seasonal Chart
Plots one line per calendar year showing the % change since the start of that year, with the current year highlighted against up to four previous years. Lining the years up on the same calendar shows whether the price tends to rise or fall in the same months, helping you spot recurring seasonal patterns. Treat it as context rather than a forecast: past seasonality does not guarantee future moves.Stacks Markets
Stacks Historical Data
About Stacks (STX)
Stacks (STX) is a blockchain that brings smart contracts and apps to Bitcoin without changing Bitcoin itself. Its blocks are anchored to the Bitcoin chain, and its consensus method, Proof of Transfer, runs on BTC that miners spend. STX is the network's native token. It rewards miners and gives signers their voting weight. Every STX price on this page comes from FMchart's composite, which merges market data from a handful of large venues into one dollar quote.
How Proof of Transfer works
Bitcoin miners spend electricity to win blocks, while Stacks miners spend BTC instead. In each round, miners commit BTC in a Bitcoin transaction, and a weighted random draw picks a winner. The winner produces that period's Stacks blocks and earns newly minted STX plus fees. The committed BTC is not burned. It pays the people who stake STX or bond BTC. Signers holding at least 70% of the weight must approve each block.
Faster blocks since Nakamoto
The Nakamoto upgrade, a hard fork in the fourth quarter of 2024, changed how blocks are made. A winning miner can now produce many Stacks blocks during one Bitcoin block, so confirmations take seconds instead of tens of minutes. Signers must approve every block, which stops miners from creating forks. After confirmation, reversing a transaction is meant to be at least as hard as reversing one on Bitcoin.
sBTC brings BTC into apps
sBTC is a token on Stacks that represents BTC one-to-one. A holder deposits BTC on the Bitcoin chain and receives sBTC, which can then be used in Stacks apps. The deposited BTC sits in a Bitcoin address controlled by a group of signers rather than a single company. Converting sBTC back returns BTC on Bitcoin. Deposits take about three Bitcoin blocks and withdrawals about six.
Staking under PoX-5
In late July 2026, the Epoch 4.0 hard fork activated PoX-5, the fifth version of Proof of Transfer. STX holders now stake by locking tokens in their own account and naming a signer-manager contract. Rewards arrive as sBTC by default, and there is no slashing. An STX-only position can be unstaked at any time and unlocks when the next cycle starts. BTC can also be paired with STX in a protocol bond, though during the current bootstrap phase that capacity goes mainly to partners chosen by the Stacks Endowment. A single staking transaction can cover anywhere from 1 to 96 reward cycles.
Issuance and risks
Stacks keeps minting new STX for miners, so the circulating supply grows over time. That issuance is separate from staking rewards, which come from the BTC miners commit. When STX prices or network activity drop, miners may commit less BTC and rewards shrink. Stacks also competes with other Bitcoin layers and sidechains. sBTC depends on its signer group, and any smart contract can contain bugs.

Stacks (STX) FAQ
What is Stacks (STX)?
Stacks is a blockchain that adds smart contracts and decentralized apps to Bitcoin. Its blocks are anchored to Bitcoin, and miners spend BTC to earn the right to produce blocks. STX is the native token: it rewards miners and can be staked to earn rewards paid out in Bitcoin terms.
Is Stacks a Bitcoin layer 2?
Stacks describes itself as a Bitcoin layer. It does not modify Bitcoin, but it records its consensus on the Bitcoin chain. Since the Nakamoto upgrade, a confirmed Stacks transaction is designed to be as hard to reverse as a Bitcoin one. Unlike some layer-2 designs, Stacks has its own token and its own miners.
What is sBTC?
sBTC is a token on Stacks backed one-to-one by BTC. Users deposit BTC on Bitcoin and receive sBTC, which they can use in Stacks apps, then convert back later. The BTC is held in a Bitcoin address controlled by a group of signers. Deposits take about three Bitcoin blocks, while withdrawals take about six.
How much is STX worth right now?
At the moment, STX is valued at roughly $0.3014 by FMchart's composite, which merges a handful of large venues into one dollar quote. Daily trading reached nearly $2.29M across the exchanges in FMchart's composite. Expect small differences between this merged quote and the price on any single venue.
What is the circulating supply of STX?
About 1,878,076,148 STX circulate, and that number rises because the protocol keeps minting STX for miners. Multiply by the current price and Stacks is worth around $566.0M, good for rank 102. Staking rewards add no STX, since miners' BTC pays for them.
What is the all-time high of Stacks?
STX's highest price so far is $3.86, from Apr 1, 2024. Since the Stacks 2.0 mainnet launched in January 2021, the token has seen big rallies and deep drops, so its distance from that peak has varied widely. Treat the record as history, not a prediction. Price Statistics also tracks STX's lowest price and today's position between the two.
What were STX's best and worst months?
In FMchart's composite price history (since January 2022), STX's top month is February 2023 (+222.0%), while April 2024 (-40.9%) is its bottom one. All other months fill the Monthly Returns (USD) table, and yearly moves sit in Annual Price (USD) Change. Large monthly swings are typical for STX, and none of them predict the future.
How do you earn Bitcoin by staking STX?
Under PoX-5, a holder locks STX in their own account and names a signer-manager contract. Miners' BTC commitments fund a reward pool, which pays protocol bonds first, then STX-only stakers from what remains. Rewards arrive as sBTC by default, and there is no slashing. Each signer-manager needs at least 50,000 STX in total stake to receive rewards.
Is Stacks a good investment?
FMchart does not provide investment advice. Stacks offers a way to use BTC in apps and to earn Bitcoin-denominated rewards. It also faces competition from other Bitcoin layers, depends on miners committing BTC, relies on sBTC signers and keeps issuing new STX. Its price has historically been very volatile.
What influences the STX price?
STX often tracks Bitcoin and overall crypto sentiment. Network-specific factors include demand for sBTC and Stacks apps, how much BTC miners commit, which shapes staking rewards, protocol upgrades such as Nakamoto and PoX-5, and new STX issuance. Competition from other ways to use BTC in DeFi also matters.
