Summer 2025’s Major Altcoin Unlocks: What You Need to Know Before the Floodgates Open

Crypto's ticking time bombs? Billions in altcoin supply set to hit markets this summer—here's how to play it.

Supply shocks incoming. While Bitcoin ETFs grab headlines, smart money's watching the altcoin unlock calendar like hawks. Projects from Arbitrum to Aptos are about to release tokens worth a combined $3.2B into circulation. Some call it inflation. Others see opportunity.

The good, the bad, and the ugly. Not all unlocks are created equal. Protocol treasuries funding development? Bullish. Early investors cashing out? Brace for impact. We break down the five biggest events—including that controversial Solana Foundation release everyone's pretending not to sweat over.

Market mechanics 101. More supply + stagnant demand = basic economics. But crypto's never been about textbook logic. Watch for hidden catalysts: staking yield boosts, exchange listings timed with unlocks, and the classic 'sell the rumor, buy the news' reversal plays.

Wall Street's watching. Traditional finance still can't tell a meme coin from a security, but they've got algorithms primed to arb these liquidity events. Meanwhile, retail traders will FOMO in after the 20% dips—because nothing teaches like repeating history.

Final thought: In a market where 'tokenomics' often means 'how fast can we dump on retail,' summer unlocks separate the builders from the bullshitters. Just remember—when VCs get liquid, someone's always left holding the bag.

The Upcoming Major Coin Unlocks

According to CryptoRank, the schedule kicks off on July 21 with the release of 108.34 million Plume coins ($12.46 million) on the Plume Network. On July 22, 14.03 million HYPER coins ($4.99 million) will circulate within Hyperlane. Avail is set to release 969.6 million coins on July 23, accounting for 9.22% of its supply, with the $19.23 million accounting for 38.1% of the project’s current value.

On July 25, AltLayer will unlock 240.8 million ALT tokens ($9.07 million). The same day will see Humanity Protocol release 91.67 million H coins ($4.96 million). On July 26, 84.29 million SAHARA coins ($7.27 million) will be introduced into circulation.

Potential Market Impact of Coin Unlocks

The total monetary value of the coin unlocks reaches $76.97 million, with Avail’s significant contribution of 38.1% and Hyperlane’s 8.01% share drawing attention. Despite comparable dollar amounts, Ronin faces a relatively low pressure of 4.83%, showcasing the influence of valuation multipliers on altcoins.

AltLayer with 6.41%, PLUME Network with 4.26%, and Sahara AI with 4.13% market ratios indicate that these coin unlocks are within the market’s capacity to absorb.

Conversely, Ronin leads in the proportion of unlocked coins at 62.9%, followed by AltLayer at 37.6%, and Avail at 21.7%.
