Plasma
A Tether-backed, Bitcoin-anchored Layer 1 purpose-built for zero-fee USDT payments and stablecoin DeFi.
Plasma is a fully EVM-compatible Layer 1 launched in September 2025, backed by Tether, Bitfinex, and Founders Fund. It runs PlasmaBFT consensus with sub-second finality, anchors state to Bitcoin, and offers zero-fee USDT transfers via a paymaster underwritten by Tether. Mainnet beta opened with $2B+ in stablecoin liquidity and 100+ DeFi partners including Aave, Ethena, Fluid, and Euler.
- TVL reported around $18.7B in Q2 2026 per DeFiLlama, though figures have been highly volatile since launch — treat snapshots as directional rather than stable.
- Not related to the 2017 Plasma scaling proposal by Buterin and Poon — this is an independent Layer 1 that reuses the name.
- PlasmaBFT consensus with sub-second block times and sub-second finality; state anchored to Bitcoin.
- Fully EVM-compatible with the ability to pay gas in USDT via a Tether-underwritten paymaster; XPL is the underlying settlement token.
- Aave, Ethena, Fluid, Euler, and Pendle integrated at or shortly after launch, giving Plasma one of the deepest stablecoin DeFi ecosystems from day one.
Frequently asked questions
How can USDT transfers be zero-fee?
A paymaster contract subsidizes gas for basic USDT transfers, funded by Tether. Complex transactions still cost gas, and users can choose to pay in USDT (converted under the hood) or XPL. Because Tether's commercial interest is USDT usage, the subsidy is expected to be sustainable, unlike similar features on smaller chains that ran out of runway.
How does Plasma anchor to Bitcoin?
Plasma commits state hashes to Bitcoin, giving it a censorship-resistance and reorg-resistance anchor on top of its own PlasmaBFT consensus. This is a weaker guarantee than a full Bitcoin L2 that inherits Bitcoin's security, but stronger than a standalone L1 with no external anchor.
Is Plasma safe for large stablecoin deposits?
Plasma is new (mainnet late 2025) and its TVL is heavily concentrated in USDT. The main structural risks are (a) reliance on Tether's continued underwriting, (b) young validator set relative to Ethereum or Tron, and (c) DeFi protocol risk on its integrated apps. Size positions to account for the chain's operating track record rather than treating the $18B+ TVL as a stability signal on its own.
