Stablechains Raise $1 Billion, But Deposits Lag Behind

The category has a cautionary example. Terra was the first purpose-built stablecoin chain. It collapsed in May 2022, erasing roughly $40 billion from the market, because its stablecoin UST was algorithmic and unsound. The collapse cut the crypto industry, but also catalyzed development of sound stablecoin infrastructure.

Together, the four new stablechains hold just under 0.3% of the $310 billion stablecoin market. Ethereum and Tron still control 78%.

The launch curves have been brutal. Plasma attracted $6.35 billion in stablecoins within two weeks of launch, then bled roughly 85% as incentives expired. Stable fared worse: despite $2 billion in pre-deposit commitments, its on-chain supply peaked at $706 million eight days after launch, then collapsed 96% to $27 million. Its stablecoin TVL has been ticking up since May 2026.

Supporters of the new chains counter that parked supply is the wrong metric for a payment rail. Velocity matters more than balances. A chain processing salaries does not need dollars sitting idle on it.

Plasma is the easiest test drive. Users can bridge in USDT and send it for free, no gas token required, or download Plasma One for a neobank-style experience. Stable works similarly with USDT0 as gas, but with fewer incentives available. Tempo takes one extra step: add the network via Chainlist, then bridge USDC or pathUSD in via Relay. Because Tempo has no token, airdrop hunters are farming a potential drop with daily check-ins and .tempo domain registrations. Arc is testnet-only, but Circle runs builder programs and is launching a fund to back early-stage teams.

Whether any of this farming pays off is speculation. The data is clear: the challengers have over $1 billion to spend closing the gap with Tron and Ethereum.
