Question 1

What is Last USD (USDXL)?

Accepted Answer

Last USD (USDXL) is a synthetic USD stablecoin designed for deployment across EVM-compatible blockchains. It is issued on Last Network, a platform built on HyperEVM, and is backed by over-collateralised crypto assets. USDXL aims to function as a fully decentralised digital dollar, combining transparency, collateral efficiency, and protocol-driven financial engineering.

The stablecoin is further supported by protocol-generated revenue, which is used to acquire tokenised U.S. treasury products. This creates a layered reserve model: collateral secures user redemptions while treasury assets provide additional liquidity depth and stability assurance. Last USD is optimised for DeFi use cases and functions as a composable stable asset throughout the broader Last ecosystem and compatible platforms.

Question 2

What is Last USD (USDXL) used for?

Accepted Answer

USDXL is primarily used as a decentralised, on-chain dollar alternative for DeFi ecosystems. It serves as:

- **Stable collateral**: Users can mint, borrow, and lend against USDXL within DeFi protocols.
- **Liquidity medium**: It can be deployed in decentralised exchanges, automated market makers, and cross-chain swaps.
- **Yield strategy base**: USDXL supports recursive borrowing, liquidity provision, and structured yield farming strategies.
- **Treasury-backed peg instrument**: A hybrid design allows USDXL to maintain stability even in volatile market conditions through dual reserve systems.

Question 3

Technical Architecture

Accepted Answer

- **Minting and Collateralisation**  
  USDXL is minted by depositing over-collateralised assets such as ETH or blue-chip tokens into smart contracts. Minting parameters are governed by risk thresholds and price oracles to ensure safety.

- **Revenue-Driven Backing**  
  Beyond user-supplied collateral, the protocol generates ongoing revenue which is directed into tokenised U.S. treasury assets. These serve as a secondary layer of backing and enable a soft floor for redemption liquidity.

- **Peg Stability**  
  USDXL uses algorithmic constraints and treasury inflows to keep its value aligned with the U.S. dollar. If deviations occur, arbitrage incentives and liquidity injection mechanisms work to restore parity.

- **Cross-Chain Compatibility**  
  Deployed on HyperEVM, USDXL is transferable across EVM networks through bridging layers and liquidity hubs, enabling multi-chain interoperability without compromising security.

- **Smart Contract Safeguards**  
  Mint/redeem functions include per-block rate limits, collateral health checks, and emergency pause mechanisms. Delegated access and admin-controlled risk parameters ensure responsible scalability.

Question 4

Who created Last USD (USDXL)?

Accepted Answer

Last USD was created by the team behind Last Network, an infrastructure-focused organisation developing scalable DeFi products on HyperEVM. The protocol is governed and maintained by a core development group specialising in synthetic asset issuance, decentralised monetary tools, and cross-chain liquidity infrastructure.
