On Nov. 11, an Argentine court froze Libra tokens belonging to Hayden Davis—the central figure in the Libra scandal—and two alleged intermediaries, citing suspicions that the assets were used to bribe public officials. The decision follows Circle’s earlier move to freeze USDC linked to the Libra team.
In recent years, token issuers have occasionally frozen funds tied to flagged addresses, typically after hacks or scams, as a way to curb illicit activity. Yet the fact that issuers can unilaterally lock holders’ assets clashes with one of crypto’s foundational principles: “not your keys, not your coins.” The question now is whether this power serves as a necessary safeguard for public integrity—or a dangerous precedent that undermines financial sovereignty.
Hayden Davis’ Tokens Frozen
Davis, a twenty-something crypto entrepreneur, was influential enough to reportedly draw in figures like Argentine President Javier Milei, U.S. First Lady Melania Trump, and even Kanye West to promote his memecoins—Libra, Melania, and YZY. While Davis now faces legal trouble, none of his ventures have resulted in a conviction. For retail investors, however, the damage has already been severe, with losses reaching into the hundreds of millions.
Launched on February 14 with Milei’s endorsement, the Libra token had no underlying utility—a textbook memecoin. Its price collapsed soon after launch, wiping out investor funds. Through his firm Kelsier Ventures, Davis reportedly pocketed around $100 million from Libra—mirroring profits from his earlier Melania token. Combined investor losses across his projects are estimated at roughly $250 million.
Davis’s gains stemmed from “crypto sniping,” a high-frequency trading tactic that exploits early access to token launches or price movements. His insider knowledge of upcoming listings allowed Kelsier Ventures to act seconds before public announcements, securing enormous early profits.
In Libra’s case, Davis allegedly used a “one-sided liquidity” setup to mask sell orders while leaving buy data visible—creating the illusion of market momentum. Investors, seeing strong upward movement, were unaware of massive sell-offs occurring behind the scenes. A similar technique was reportedly used in March to offload Melania tokens.
In May, a U.S. judge ordered the freezing of $57 million in USDC tied to Libra. Circle, the stablecoin’s issuer, complied, locking the funds. But by August 20, those assets were reportedly unfrozen, giving Davis and his associates access once again.
Exactly how the Libra tokens are being frozen remains unclear. Built on the Solana blockchain, Libra can use a “freeze account” function that halts token issuance. Circle likely relied on this mechanism to freeze USDC linked to Libra addresses on Solana. However, there’s no direct evidence it was employed in this case. Chainalysis notes that authorities can also “freeze” crypto simply by transferring assets into a government-controlled wallet—effectively seizing them without modifying the underlying token code.
Blockchains Can Freeze Tokens
While the exact method used to freeze Libra tokens remains uncertain, it’s no secret that centralized stablecoin issuers possess the power to halt user funds. That authority was further cemented by the GENIUS Act, signed into law by President Trump on July 18, which requires both U.S. and foreign stablecoin issuers to freeze assets when deemed necessary. The rationale: stablecoin issuers operating in the U.S. are legally recognized as financial institutions and must comply with all applicable regulations.
Even before the GENIUS Act, issuers routinely froze funds in response to hacks or scams. Circle’s action against Libra-linked USDC is far from unique. Following the Cetus Protocol hack on May 22, 2025—which drained $200 million in crypto—the Sui Foundation froze $162 million in stolen tokens. While the intervention helped recover most of the funds, it also reignited debate over the dangers of concentrated control in decentralized systems.
The incident prompted Bybit’s Lazarus Security Lab to conduct a deeper analysis of blockchain-level asset control. Their study, “Examine the Impact of Fund Freezing Ability in Blockchain,” released on Nov. 12, 2025, examined the codebases of 166 blockchains. Researchers found that 16 networks can already freeze holders’ funds without consent, and another 19 could implement such capabilities in the future.
According to the report, these mechanisms take several forms—hardcoded blacklists (public freezes), config file–based blacklists (private freezes), and on-chain smart contract freezing. The blockchains confirmed to have active or potential freezing functions include BNB Chain, Sui, VeChain, Cosmos, and twelve others.
Lazarus researchers warn that these mechanisms effectively reintroduce centralized control, running “counter to the core principle of decentralization.” Their goal, however, is transparency: to help token holders understand the risks of fund-freezing systems and take proper precautions. After all, unexplained freezes are becoming increasingly common—and risk awareness may be the only real safeguard left.
