STRK Explained: Starknet's Volatility, Sessions and Key Levels

STRK is the native token of Starknet, a zero-knowledge (ZK) rollup on Ethereum: it pays transaction fees on the network and is staked to secure it. For a trader, two things define it: it moves far more than most large coins, and part of its supply is still on a published unlock calendar. Over the 90 days to 14 October 2026 STRK's average daily range was 10.49%, 3.83 times Bitcoin's, and its daily returns correlated only 0.40 with BTC. CoinGecko shows 74% of the 10 billion total supply in circulation, and Starknet's docs schedule up to 127 million STRK to unlock on the 15th of each month until March 2027.

Below: what Starknet is and what STRK does, our 90-day hourly and weekday profile, the unlock calendar, where STRK trades, the BTC link and a 1h structure read. Every number is computed from dated data or taken from a source we fetched on 15 October 2026.

What is Starknet and what is STRK used for

Starknet's documentation (docs.starknet.io, checked 15 October 2026) describes STRK as the network's token for staking, and its fees page says that since Starknet v0.14.0 every transaction specifies STRK-denominated fee limits and the fee is charged in STRK. Holders can stake directly as validators, which needs a minimum of 20,000 STRK on Mainnet, or delegate to validators that accept delegation. Staking rewards are paid in newly minted STRK, and funds that signal an unstake stay locked for 7 days on Mainnet.

The tokenomics page says ten billion STRK were created by StarkWare in May 2022 and minted onchain on 30 November 2022. CoinGecko (15 October 2026) ranks STRK 101st by market cap at $0.0874 and files it under Layer 2 (L2), Zero Knowledge (ZK) and Rollup. In trading terms: a mid-cap infrastructure token whose price reflects the market's view of Ethereum scaling, with a large share of its supply held by early backers.

How STRK trades: the 90-day fingerprint

We took every 1h STRKUSDT candle from 17 July to 14 October 2026 (2,160 candles, Binance) and averaged the high-to-low range for each UTC hour.

• Average daily range: 10.49%. Bitcoin's was 2.74% over the same window, so STRK's is 3.83 times wider.
• Busiest hour: 14:00 UTC (17:00 MSK), averaging 2.33% per hour, then 13:00 (2.30%) and 16:00 (2.21%).
• Quietest hour: 06:00 UTC (09:00 MSK), at 1.51%. The peak is 1.5 times wider.
• By session (our UTC buckets): 13:00 to 21:00 averages 2.03% per hour, 00:00 to 08:00 averages 1.80%, 08:00 to 13:00 averages 1.74% and 21:00 to midnight averages 1.73%.

The pattern is a New York afternoon peak on top of a high floor: even the quietest hour moves 1.5% on average. The trading sessions tool shows these windows in your own time zone, and the best time to trade crypto study covers the same method for majors.

Weekdays and wide days

Over the 90 daily candles (17 July to 14 October), STRK's weekend is its widest part of the week. Saturday averaged a 14.53% range and Friday 13.75%, against 7.26% on Tuesday, the narrowest day. Weekend days averaged 12.52% against 9.66% on weekdays, so unlike many majors STRK does not go quiet on weekends.

71 of the 90 days (79%) had a range above 5%, and the median day was 7.91%. The three widest were 18 September (57.0% range, closing 52.6% above the open), 10 October (53.6%, +41.3%) and 9 October (39.3%, +31.5%). We attach no news to those days: we have no dated source that ties them to a specific event, and a story without a source is a guess. The practical point is that these few days lift the averages above. A 5% stop sits inside STRK's ordinary daily noise.

STRK supply and unlocks

CoinGecko on 15 October 2026: 7.42 billion STRK circulating, 10 billion total supply, a $649 million market cap and an $875 million fully diluted valuation (FDV), about 1.35 times market cap.

The unlock calendar comes from the Starknet documentation's STRK page. It splits the allocation into Early Contributors (20.04%) and Investors (18.17%), which are locked, and groups such as StarkWare (10.76%), Grants (12.93%), Community Provisions and Rebates (9.00% each), Foundation Strategic Reserves (10.00%) and Foundation Treasury (8.10%). Investor and Early Contributor tokens unlock monthly on the 15th, in two phases:

• Phase 1: up to 0.64% of total supply (64 million STRK) a month, 15 April 2024 to 15 March 2025.
• Phase 2: up to 1.27% (127 million STRK) a month, 15 April 2025 to 15 March 2027.
• What is left: 15 October 2026 is itself an unlock date. After it, five more monthly unlocks remain (15 November to 15 March), up to 635 million STRK in total, or 8.6% of today's circulating supply.
• Our sum of both phases: up to 3.816 billion STRK, 38.16% of total supply, close to the 38.21% the docs allocate to the two locked groups.

At $0.0874, one 127 million tranche is roughly $11 million, against $28 million of 24-hour spot volume on Binance alone. The docs say "up to", and that locked holders cannot transfer, sell or pledge; an unlocked token is not necessarily a sold token, and we do not publish a recipient breakdown because the page states none.

Where STRK trades

We read 24-hour spot volume from the public tickers of nine venues on 15 October 2026 at about 10:10 UTC.

Binance printed $28.3 million and OKX $27.3 million, together 56% of the $98.7 million across the nine. Coinbase (about $10.3 million, converted from STRK volume at the last price), Gate ($9.0 million), Bybit ($8.3 million) and Kraken (about $6.0 million) follow, with KuCoin, MEXC and Bitget smaller. Derivatives dwarf spot: Binance's STRKUSDT perpetual traded $245 million, 8.7 times its spot volume, and Bybit's perpetual traded $89.6 million against $8.3 million spot.

STRK vs BTC

Over the 90 days, STRK's daily returns correlated 0.40 with Bitcoin's. In our SUI post the same calculation gave 0.68, so STRK is much less BTC-led and has more of its own noise. 0.40 squared is 0.16: only about a sixth of STRK's daily variance lines up with BTC.

The rolling 30-day correlation started at 0.32 on 16 August, touched 0.22 on 18 August, climbed to 0.65 by 21 August and peaked at 0.71 on 20 September. It dropped to 0.48 the next day, then drifted down to 0.38 on 10 October and ended at 0.45. A reading that moves this much means the BTC link is not stable, so recheck it before using BTC as a proxy. The Bitcoin guide covers the benchmark.

Reading STRK's structure

The chart shows STRKUSDT on the 1h timeframe from 12 to 15 October 2026, with the BiasNex engine's structure events and the previous-day high (0.0866) and low (0.0751).

Price fell from 0.107 on 12 October. The engine marked a bearish change of character at 0.0820 and a bearish break of structure at 0.0826, both at 05:00 UTC on 14 October, and a second bearish BOS at 0.0751 at 04:00 UTC on 15 October. At 07:00 UTC price wicked to 0.0718, below the previous-day low, and was back at 0.0874 by the 09:00 UTC close, above the previous-day high. In market structure terms that is lower lows followed by a liquidity sweep-style probe of the low and a sharp recovery; at 10:12 UTC the engine read bias as bullish in a pullback context. The live read is on the STRK markets page, where you can also add STRK to your watchlist and get structure alerts on Telegram. The chart is a snapshot of 15 October.

Risks

• Supply keeps arriving. Up to 127 million STRK is scheduled to unlock on the 15th of each month until March 2027.
• Very wide range. At 10.49% a day, a tight stop is taken out by ordinary movement. Size from the stop with the position size calculator.
• Spike days. Three days in 90 closed 31% to 53% above the open; the move can be as sharp in the other direction.
• Derivatives-heavy. Perpetual volume is roughly 9 to 11 times spot on the two venues we checked, so funding and liquidations can drive moves that spot volume does not explain.
• Unstable BTC link. The correlation ranged from 0.22 to 0.71 in two months.
• Browse the category. See other coins in the Coin Library.
