LABtrade — Insider OTC/Vesting/Supply Manipulation — 2026-05-14

Loss
Retail investors in $LAB token. Market cap crashed after insiders extracted via private OTC deals, vesting changes, and CEX deposits. FDV at peak: $6B.
OAK Techniques observed
OAK-T3.006 (Insider Multi-Vector Supply Extraction — the canonical anchor; the LABtrade team deployed four simultaneous extraction mechanisms — private OTC/loan deals, unilateral vesting changes, market maker coordination, and CEX deposit dumping — that individually appeared benign but collectively formed a coordinated retail extraction architecture. See techniques/T3.006-insider-multi-vector-supply-extraction.md). OAK-T3.004 (Influencer Amplified Promotion and Dump — secondary; the TGE and public promotion provided the demand-side amplification for the multi-vector extraction architecture).
Attribution
confirmed — Vladimir "Vova" Sadkov (co-founder), Mark (co-founder), and connected insider wallets. On-chain links to RIVER token manipulation ($12M+ received by same insider).
Key teaching point
The LABtrade case demonstrates multi-vector insider extraction — the team deployed four simultaneous extraction mechanisms (private OTC/loans, vesting cliff changes, MM coordination, CEX deposit dumping) which individually appear as separate activities but collectively form a coordinated retail extraction strategy. Detection requires cross-referencing: (1) off-chain governance actions (vesting terms), (2) on-chain insider wallet clustering, (3) CEX deposit timing vs. price action.

Summary

On May 14, 2026, ZachXBT published a 9-part investigation into LABtrade ($LAB), a trading platform co-founded by Vova Sadkov and Mark that TGE'd in October 2025. Despite reaching a $6B fully diluted valuation, the token exhibited a pattern of coordinated insider extraction across four vectors:

  1. Private OTC/Loan deals: Loan contracts offered privately at 7.5%/month for 6 months via a BVI shell company (The Lab Management Ltd., signed by Vladimir Sadkov as director). On default, repayment was in $LAB at "market price" — allowing insiders to extract value regardless of token performance.

  2. Unilateral vesting changes: The Legion public sale terms were changed from a 3-month cliff to a 9-month cliff without community consent. Other creators reported months-long delays in marketing campaign payouts.

  3. CEX deposit dumping: 226M LAB (a large percentage of the float) was deposited to Bitget deposit addresses by insiders in March-April 2026. The deposits sat dormant until 100M LAB was withdrawn, generating significant social media coverage, then potentially dumped.

  4. Supply opacity: No clear token distribution was available — CoinGecko, RootData, and CoinMarketCap all reported different supply figures. The team controlled >95% of supply.

  5. RIVER connection: One of the signers for several LAB team multisigs (0xcEA722a1A812EbDFA5BBD8130531cF1D1956eBC9) was funded by an insider linked on-chain to RIVER token manipulation. The same insider received $12M+ of RIVER tokens to two CEX deposit addresses.

The borrower wallet from the LAB loan contract (0xf09c...) was the same wallet used for public LAB buybacks, blurring the line between treasury management and insider extraction.

Timeline

When Event OAK ref
2025-10 LABtrade TGE. Vova Sadkov & Mark co-founders. Prior project Eesee ($ESE) abandoned — investors left with losses (background)
2025-10~2026-04 Private OTC/loan deals offered via BVI shell. Vesting terms changed unilaterally (3-month → 9-month cliff). MM coordination established T3 insider positioning
2026-03~04 226M LAB deposited to Bitget deposit addresses by insiders. Deposits sit dormant T3 CEX staging
2026-04~05 LAB price pumps to $6B FDV. Retail buys based on public information. Insiders, OTC buyers, and MMs have different (private) information sets T3 information asymmetry
2026-05-14 ZachXBT publishes investigation: opaque loans/OTC, vesting changes, MM coordination, unknown float, >95% supply control (public disclosure)

What defenders observed

  • Governance actions without community process: Vesting terms changed from 3-month to 9-month cliff unilaterally. No governance vote, no community discussion. The change was discovered via leaked email screenshot.
  • BVI shell structure for insider loans: The Lab Management Ltd., a BVI corporation, was the borrower on private LAB loan contracts. The director was Vladimir Sadkov (co-founder). Loan terms (7.5%/month, repayment in LAB at "market price") were structured to benefit insiders regardless of token performance.
  • Borrower wallet = buyback wallet: The loan contract borrower address (0xf09c...) was the SAME wallet used for public LAB buybacks — making treasury outflows indistinguishable from insider extraction.
  • CEX deposit cluster: 226M LAB deposited to Bitget from insider-linked addresses that sat dormant, then were withdrawn with social media amplification before potential dump.
  • Multi-project pattern: The co-founders' prior project Eesee ($ESE) left investors "feeling abandoned after the team moved on" — the extraction pattern was not a one-off.

What this example tells contributors writing future Technique pages

  • Multi-vector extraction is T3's most sophisticated form. Individual vectors (OTC, vesting, MM, CEX dump) are each covered by existing T3 sub-techniques, but the coordinated use of all four simultaneously — with the structural opacity to hide each from investors seeing only one — is not yet explicitly modelled. A T3.006 (Insider Multi-Vector Supply Extraction) sub-technique may be warranted.
  • The borrower-wallet = buyback-wallet pattern is a specific detection signal. When the address receiving loan proceeds is the same address executing buybacks, treasury and insider flows are commingled by design. This is detectable on-chain: the same address both receives from the protocol treasury and sends market-buy transactions.
  • CEX deposit dormancy + withdrawal + social amplification → dump is a timing signal. 226M LAB sat dormant on Bitget for weeks, then 100M was withdrawn with significant CT coverage, enabling a dump while retail attention was on the "bullish" withdrawal narrative.
  • Cross-project pattern (Eesee → LABtrade) is an attribution signal. Founders who abandoned a prior project with investor losses are more likely to repeat the pattern. OAK actor profiles should track serial founders across projects.
