SIREN: three pumps, a 92% two-day crash, and another round pushed up and knocked down on perps

Subject: the SIREN contract on BNB Chain 0x997a58129890bbda032231a52ed1ddc845fc18e1 (SirenAI) and the Binance SIRENUSDT perpetual. Times are UK time. On-chain data comes from every BNB Chain transfer, perp data from Binance’s public APIs, and holdings from GoPlus and on-chain nodes.

The short version

1. Today’s drop barely shows up on-chain. From 01:00 on 19 October SIREN slid from 0.0346 to 0.0214 (−38%), back below where it started on 15 October. The largest single on-chain seller today sold only about 1.97 million tokens, about $50,000; net selling into the main PancakeSwap pool for the whole day was about 6.5 million tokens, about $170,000. Binance perps traded about $50 million on the same day. Both the rise and the fall happened on perps.

2. It is not the first time. In early February 2026 SIREN was around 0.08; on 22 March it hit an intraday 4.81 on the Binance perp, roughly 60 times higher. On 13–14 June it fell from 0.474 to 0.039, down 92% in two days. Lookonchain counted one whale selling about 670 million tokens in those two days for about $64.8 million USDT. It is now 99.6% below its all-time high.

3. The June dump used tokens gathered on every earlier pump day. We traced six dormant wallets, each used only once or twice. Their tokens arrived on 6 February (the day before the 7 February surge), 22 March (the all-time-high day), 4 April and 28 April (both pump days) and then sat untouched. After the crash began in the early hours of 13 June, at 05:07–06:36, these six wallets moved 173 million SIREN (about 17% of supply) to fresh addresses; from 08:00 the next morning the tokens were split up and sold into PancakeSwap through aggregator routers, matching the second leg down on 14 June from 0.13 to 0.06.

4. The contract is fine; the problem is who holds the supply and the perp market. The contract is verified, cannot mint, has no owner and charges no tax. Of the 1 billion supply, 27.7% was burned in launch week; 38% now sits in Binance Wallet’s custody contract, where the owners cannot be seen. All spot trading is about $4.3 million a day against about $84 million on Binance perps, roughly 19 times as much.

What SIREN is

SIREN is a BNB Chain token launched on four.meme in February 2025. Its website calls it “the first AI analyst agent deployed on BNB Chain” and promotes an AI trading assistant, a cross-chain AI trading agent and an “AI economy”.

• Product: all three are marked Coming Soon on the website (visited 19 October). Eighteen months after launch we found no product or usage data we could verify.
• Team: the website names no members and no company.
• Endorsements: the website lists a $25,000 SIREN purchase by the BNB Chain Foundation under its $100 million incentive programme, plus listing announcements from Bybit, Bitget, KuCoin, HashKey and others. Binance has no SIREN spot market, only Binance Alpha and the SIRENUSDT perpetual (listed 22 March 2025).
• Contract code: verified, no minting, ownership renounced, no tax and no blacklist (GoPlus).

Price: up 60×, then down 99.6%

• 2025: mostly between 0.04 and 0.2.
• 7 February 2026: from 0.09 to an intraday 0.39 in a day, on $830 million of perp volume, then back to 0.09 the next day.
• 22 March: from 0.94 to an intraday 4.81, on $2.8 billion of perp volume that day, closing at 2.31. Wild swings followed, down to 0.56 by 31 March.
• Late March: on-chain analytics firm Bubblemaps and investigator ZachXBT publicly warned that a cluster of more than 200 wallets controlled about half the supply (CryptoPotato).
• April to early June: two more pumps, to an intraday 2.24 on 17 April and 1.36 on 7 June.
• 13–14 June: from 0.474 to 0.039, down 92% in two days (The Defiant, Lookonchain).
• June to mid-October: sideways between 0.02 and 0.04, with only a few million dollars of perp volume a day.

The June dump: where the tokens came from and how they were sold

The crash began at 01:00 on 13 June; by 05:00 the price had fallen from 0.47 to 0.25, and by 07:00 to 0.11. We pulled every on-chain transfer from 01:00 to 06:37. Those 5.5 hours alone contained more than 400,000 SIREN transfers, and the largest came from one kind of address: dormant wallets used only once or twice, whose tokens had sat untouched for months.

The tokens were gathered on pump days. Tracing each of the six wallets back:

6 February was the day before the 7 February surge, 22 March was the all-time-high day, and 4 April was another pump day. “Exchange hot wallets” are inferred from transaction counts (these three addresses have between 4.6 million and 16 million transactions each); which exchanges they belong to cannot be verified publicly.

Moved mid-crash, sold the next day. At 05:07–06:36 on 13 June, with the price already halved, the six wallets sent a total of 173 million SIREN to new addresses. Those addresses split them into lots of 2–8 million, passed them on to more new addresses, and sold them into PancakeSwap through DEX aggregator routers a few thousand tokens at a time. For example, 0xf416…ca9c received 8 million and sold them in 1,323 transfers between 07:55 and 11:49 on 14 June; 0xcd98…71d4 sold its 7 million in 962 transfers between 08:01 and 08:52. That is exactly the second leg down on 14 June: from 07:00 to 12:00 the price fell from 0.126 to 0.064.

Address poisoning appeared at the same time. Next to these new addresses, look-alike addresses with identical first and last characters appeared and sent them zero-value transfers (for example 0x4c0efa73…9f52 next to 0x4c0e6736…9f52). It is a common scam: someone copying an address from their history sends funds to the fake.

What third parties say. Lookonchain counted this whale selling about 670 million SIREN in two days for about $64.8 million USDT, of which $25.7 million went to exchanges. ZachXBT said the wallets were linked to several projects backed by DWF Labs; that is his inference from on-chain links, DWF Labs has not confirmed it, and we cannot verify it (CryptoPotato). The chart and table show only what we could verify transfer by transfer; we did not re-check the full 670 million ourselves.

October: pushed up on perps, knocked back down on perps

• Take-off: volume jumped from 13:00 on 15 October, taking the price from 0.021 to 0.032 in three hours. As it happens, AGT also doubled on perps that same afternoon.
• Peak: an intraday 0.0414 on 17 October, about twice the starting level.
• Today: in the 01:00 hour the price went from 0.0346 to 0.0290, and by 15:00 it was 0.0211, below where it started on 15 October.
• Open interest: from $8.1 million to $15.9 million on 16 October, now back to about $9.1 million.
• Retail account long/short ratio: 4–5 for a long time before the move, meaning about 80% of accounts were long; it dropped to 1.66 during the pump (retail shorting the rally) and rose back to around 4 as the price fell (retail buying the dip). The top-trader position ratio stayed between 1.3 and 1.7.
• Funding: settled every four hours and mostly within ±0.1%, apart from one −0.16% print at 13:00 on 16 October.

The driving force does not show up on-chain. From 12:00 on 15 October to 09:00 on 16 October, net outflow from the main PancakeSwap pool (that is, net buying) was only about 3.76 million tokens, about $100,000; the largest single buyer bought about 5.11 million. Over the same period Binance perps traded $290 million across two days. Today was the same: the largest single seller sold about 1.97 million tokens, while perps traded about $50 million.

For a token with only a few million dollars of daily spot trading and perp volume ten to fifty times that, the price is mostly set by perp money. Neither the rise nor the fall needs anyone to buy or sell much on-chain.

Supply: where the 1 billion SIREN sit now

• 27.7% burned, all in launch week. On 9–11 February 2025 one address bought 198.6 million from the PancakeSwap pool and burned them all on 14–15 February; the deployer also burned the 60.98 million it received at launch on 15 February.
• 38% in Binance Wallet’s custody contract: 0x73d8…46db holds users’ tokens in Binance Wallet / Binance Alpha, and the individual owners cannot be seen. Third parties say the whale still held several hundred million tokens after June; some of that may sit here, but we cannot verify it.
• About 6.4% in exchange hot wallets: two of the three hot wallets mentioned above, plus their linked contracts.
• 3.2% in the main PancakeSwap pool: V3 SIREN/WBNB, 1% fee tier.
• 1.3% with one steady buyer: 0xeb20…a5b has bought in at least 2,000 small transfers through a router since 5 September, and was still buying on 15 October and today. Its identity is unknown.

Scorecard

Possible paths from here

• Sideways between 0.02 and 0.03 (about 50%): perp volume returns to a few million dollars a day, as from June to mid-October.
• Another perp-driven pump (about 30%): spot is so thin that perp money can easily double the price and knock it back again, as this round just showed.
• The cluster sells the rest (about 15%): third parties say several hundred million tokens remained with the same cluster after June. If that starts moving, today’s depth would struggle to absorb it.
• The project ships a real product or names its team (about 5%): the website’s products have been Coming Soon for 18 months.

What to watch

1. Binance perp data: a sudden jump in open interest while the retail long/short ratio drops fast (retail shorting) is the classic precursor of a pump in tokens like this; open interest falling while the ratio rises again usually marks the end.
2. New addresses on the June dump path: if “dormant wallet → fresh address → split → sold through routers” appears again, the cluster is selling.
3. SIREN balance in the Binance Wallet custody contract: large withdrawals on-chain may mean big holders are moving tokens out of Binance Wallet to sell on-chain.
4. The steady buyer 0xeb20…a5b: if it stops buying or starts selling, that is a signal.

Closing

SIREN’s contract has no back doors; everything in this issue happens outside it: no product after 18 months, supply held by a cluster, and a price set by the perp market. In June the tokens had been quietly gathered on every pump day, moved to new addresses as the crash began and sold in bulk the next day. In October nobody even needed to trade much on-chain: perps alone doubled the price and then put it straight back.

For tokens like this, headlines and calls tell you little. Watching when those dormant wallets wake up, and when perp open interest suddenly jumps, is a more reliable signal.
