Tentang Last USD
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.
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.
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.
