Solana Under Fire Again — Expert Reveals Why It Isn’t Out Of Beta Yet

A fresh bout of public scrutiny has erupted around Solana which still labels its mainnet “beta” more than five years after launch. The latest flashpoint unfolded on X, where Helius Labs chief executive Mert Mumtaz sparred with pseudonymous critic Balarchrex over the meaning of the beta tag, the opacity of Foundation wallets and the true extent of client diversity on SOL’s validator network.

Why Is Solana Still In Beta?

The exchange began when Balarchrex accused Mumtaz and Solana co-founder Anatoly Yakovenko of avoiding three contentious topics: “Solana still being in beta, Solana foundation wallets not being public, [and] Solana having one single client.” He dismissed Firedancer—the validator client under development by Jump Crypto—as little more than vaporware. Mumtaz, who leads a prominent Solana infrastructure company, replied that the beta label “is arbitrary and meaningless,” arguing that the chain already “does more scale and revenue than all chains combined while in ‘beta.’”

Pressure quickly shifted to transparency. Balarchrex demanded an on-chain accounting of the Solana Foundation’s holdings, warning that “no institution will ever take SOL seriously as an investment when they have no idea how much SOL is dumping on them.” Mumtaz countered that market behavior suggests otherwise: “Then why are they buying it and expanding to it? Curious.” He added that observers can “easily figure out a range of how much the foundation holds,” but stopped short of providing wallet addresses or precise balances.

Client diversity became the third rail of the conversation. Mumtaz listed three clients already running on mainnet—“agave, jito-agave, frankendancer”—and noted that Firedancer “is already being tested extensively and will be live Q3/Q4.” In his view, the presence of multiple independent teams contributes to code quality: “jito/anza routinely discover new bugs before they make it to production; having 2 independent teams working on same core code and fixing it is now randomly an issue?”

Balarchrex dismissed agave and jito-agave as “just forks of the original Solana code” and pressed for statistics on validator adoption. Mumtaz pointed critics to publicly accessible dashboards such as Solanabeach and validators.app, insisting that the data “is not hidden.”

The beta label, however, refused to fade from the discussion. Balarchrex resurfaced a recent status-update screenshot that still includes “beta” in the mainnet build name and asked why the term resurfaces “every time Solana goes down.” Mumtaz replied that Balarchrex had “hallucinated that entirely,” asserting that the chain has gone down once in over 2 years (and that was due to a devops issue) and that he has “already said the name should be removed several times.”

As tempers frayed, the debate devolved into personal barbs. Balarchrex summarized his position: “Solana is still in beta… The validator clients are the same original code with minor changes… you have still not addressed my points.” Mumtaz dismissed the critique as “grasping at straws,” reiterating that nomenclature has no bearing on the network’s production readiness and suggesting that anyone worried about token supply should “sell your SOL if you’re concerned, I will happily buy it.”

At press time, SOL traded at $148.
