Just over a day ago, the crypto world witnessed the launch of Plasma, a fresh Layer 1 blockchain that's already making waves. According to a recent post from Castle Labs on X, Plasma has amassed around $3.5 billion in Total Value Locked (TVL)—that's the total amount of assets deposited into the protocol for lending, borrowing, or other DeFi activities. This rapid growth positions Plasma as Aave's second-largest instance, right behind the Ethereum mainnet itself.

For those new to the scene, Aave is one of the leading decentralized finance (DeFi) protocols where users can lend and borrow cryptocurrencies without intermediaries like banks. Plasma's integration with Aave means users can tap into these services on this new chain, benefiting from potentially lower fees and faster transactions compared to congested networks like Ethereum.

What's turning heads is Plasma's USDT lending vault, which is still dishing out yields north of 20% on more than $2 billion in deposits. USDT, or Tether, is a stablecoin pegged to the US dollar, making it a go-to for investors seeking stability. These high yields are likely fueled by launch incentives, such as token rewards or boosted rates to attract liquidity early on. But as one reply to the post pondered, will these eye-popping returns hold up over time?

Plasma's mainnet beta went live on September 25, 2025, backed by Bitfinex and integrated with protocols like Ethena for USDe and sUSDe assets across Aave, Curve, Balancer, and Fluid. This setup kicked off with over $1 billion in USDT TVL on Aave, quickly ballooning thanks to strong investor interest. The native XPL token has also seen a surge, reflecting the hype around the launch.

In the broader context, Plasma's success defies the odds for new Layer 1 chains, which often struggle to gain traction. Here, it hit $2 billion TVL in stablecoins at launch, vaulting into the top 10 blockchains by that metric. This isn't just about numbers—it's a sign of shifting dynamics in DeFi, where new networks can rapidly capture market share with smart integrations and incentives.

If you're a blockchain practitioner eyeing meme tokens or DeFi opportunities, Plasma's story underscores the importance of monitoring launches like this. High yields can be enticing, but always do your due diligence—check for risks like smart contract vulnerabilities or market volatility. For more details, head over to the original post on X.
