Launched in 2020, Sperax is headquartered in NYC. After envisioning a Sperax Layer 1 blockchain, the team transitioned to building the first auto-yield-bearing stablecoin: Sperax USD (USDs).
In December 2021, Sperax released USDs on L2 Arbitrum. Residing on-chain, USDs is backed by collateral and algorithmically by the protocol’s ability to mint $1 worth of SPA when redeeming $1 of USDs. USDs combine the scalability benefits of algorithmic stablecoins with the stability benefits of collateralized stablecoins.
USDs holders benefit from native auto-yield, meaning that holders automatically earn yield without having to stake or claim. The yield is generated organically from the collateral deployed on external Defi protocols like Curve Finance.
Sperax’s roadmap is to construct a full-stack Defi ecosystem based on USDs. As the USDs ecosystem expands through organic and partnership growth, the team plans to vitalize the L1 conceived during the company’s incipient stage.
Sperax has received $7 million in early funding. Sperax is backed by Polychain Capital, Jump Trading, Alameda Research, Amber Group, and DJ Steve Aoki.

What is the meaning of Layer 2?
Layer 2 in the context of cryptocurrency and blockchain technology refers to a secondary framework or protocol that is built on top of an existing blockchain system (the main chain or Layer 1)
The primary purpose of Layer 2 solutions is to solve the scalability and speed issues that many blockchains face, especially those that have become popular and heavily used, like Ethereum
Here are the key aspects of Layer 2 solutions:
- Scalability Enhancement: They help in scaling the main blockchain by handling transactions off the main chain. This reduces the burden on the main chain, allowing for faster and cheaper transactions.
- Types of Layer 2 Solutions: There are various forms of Layer 2 solutions, including state channels, sidechains, plasma chains, and rollups. Each has its own mechanism for interacting with the main chain and handling transactions.
- State Channels: These involve two parties engaging in numerous transactions outside of the main chain, which are then consolidated into a single transaction. This is especially useful for situations where multiple transactions occur between the same parties.
- Sidechains: These are separate blockchains that are connected to the main chain via a two-way peg. They operate independently and can have their own consensus mechanisms but are secured by the main chain.
- Plasma Chains: Plasma chains are similar to sidechains but with a more hierarchical structure. They report back to the main chain regularly and are optimized for mass transaction handling.
- Rollups: Rollups process and store transaction data on a sidechain but post transaction data to the main chain. They come in two varieties: optimistic rollups and zk-rollups, each with its own method of transaction verification.
- Security Considerations: While Layer 2 solutions are generally secure, they can have different security models compared to the main chain. This is an important consideration for users and developers.
- Impact on User Experience: For end-users, Layer 2 solutions can greatly improve the experience by reducing transaction fees and increasing transaction speeds.
- Adoption and Development: Many blockchain projects are actively developing Layer 2 solutions to enhance their networks. This is an ongoing area of innovation in the blockchain space.
