Counterparty warning: Token Metrics recommends enhanced due diligence before giving Nguyen Van Thanh, also known as Thành Nguyễn, access to source code, credentials, wallets, smart contracts, trading systems, or other sensitive infrastructure.
Thanh completed a Token Metrics contractor/work trial from December 5–16, 2025. In February and March 2026, Token Metrics’ administrative/deployer key was used to remove approximately 2.11 billion TMAI from three Base contracts. The tokens were transferred to a Gnosis Safe and sold through CoW Protocol. Token Metrics traced at least 42,094.28 USDC in four cash-outs from the incident-linked Safe and cash-out infrastructure.
The $42K+ figure describes documented traced cash-outs, not the complete market value of the 2.11 billion TMAI removed.
Token Metrics’ investigation identified Thanh as a specific attribution lead. This was not based on a random name or wallet adjacency.
Why Token Metrics identified Nguyen Van Thanh
- Wallet
0x4BA938F3541191A824A71198B9DFAD464C27338cwas cryptographically linked to the Polymarket username thanh081101. - The username matches Thanh’s name and the November 8, 2001 date of birth in his Token Metrics onboarding record.
- Drain-linked infrastructure sent approximately 10 USDC to that wallet after the incident.
- The wallet repeatedly transferred assets to Binance deposit address
0x8Aa6e8A46B458d15702E1Ea120D6A7Fd11daCce1. - Thanh later confirmed in writing that he owns both the personal wallet and the Binance deposit address.
- His own Binance export corroborated his control of that deposit endpoint.
