TerraClassicUSD (USTC) is a decentralized, algorithmic stablecoin built on the TerraClassic blockchain, originally launched as TerraUSD (UST). Designed to power scalable DeFi solutions across chains, USTC serves as the native token of the TerraClassic ecosystem. While traditional stablecoins like USDT and USDC are backed and managed by centralized entities, USTC operates under a fundamentally different model—one rooted in decentralization and algorithmic supply control.
Unlike asset-collateralized stablecoins, USTC relies on an algorithmic mechanism tied to another native cryptocurrency: Luna Classic (LUNC). This design aimed to create a self-sustaining financial system without reliance on fiat reserves, positioning USTC as a bold experiment in decentralized finance innovation.

How USTC Maintains Its Peg
The core mechanism behind USTC’s price stability involves a dynamic mint-and-burn system connected to LUNC. When users want to mint 1 USTC, they must burn $1 worth of LUNC. Conversely, they can always burn 1 USTC to receive $1 worth of LUNC, regardless of the market price of either token.
This arbitrage-friendly structure creates economic incentives for traders to act when USTC deviates from its $1 peg. For example:
- If USTC trades below $1 (e.g., $0.95), arbitrageurs buy it cheaply and redeem it for $1 worth of LUNC, locking in risk-free profit.
- If USTC trades above $1 (e.g., $1.05), users mint new USTC using LUNC and sell it on the open market for immediate gain.
In theory, these actions stabilize USTC’s price around $1. However, this model depends heavily on market confidence and sufficient liquidity in LUNC.
Despite these mechanisms, USTC lost its dollar peg in May 2022 amid a rapid loss of investor trust and spiraling sell-offs in LUNC. Since then, USTC has continued trading on the original TerraClassic blockchain but remains unpegged, with its value fluctuating based on market dynamics rather than algorithmic stability.
The Evolution of Terra: From UST to USTC
Following the collapse of the original Terra ecosystem, the community made a critical distinction between legacy and new assets:
- UST was rebranded as USTC (TerraClassicUSD), remaining on the old chain.
- A new version of the protocol, Terra 2.0, launched without an algorithmic stablecoin.
- The original LUNA became Luna Classic (LUNC), while the new chain introduced a fresh LUNA token.
Do Kwon, co-founder of Terraform Labs, confirmed that there are no plans to migrate USTC to the new Terra blockchain or reintroduce algorithmic stablecoins on Terra 2.0. As a result, USTC exists today primarily as a remnant of the pre-crash ecosystem, traded by speculative investors and long-term believers in its potential revival.
Multi-Currency Stablecoin Ecosystem
Before its depegging event, Terra envisioned a global network of algorithmic stablecoins pegged to various fiat currencies. These included:
- TerraKRW (KRT) – pegged to the South Korean won
- TerraMNT – linked to the Mongolian tögrög
- TerraEUR – designed for the euro
These stablecoins allowed users to swap between different fiat-pegged tokens with minimal fees, enabling seamless cross-border transactions and hedging against local currency volatility. The interoperability between Terra’s stablecoins was one of its most innovative features—offering a glimpse into a decentralized, multi-currency digital economy.
While many of these projects are now inactive due to the collapse of the ecosystem, they demonstrated the potential for blockchain-based financial inclusion on a global scale.

USTC Supply and Economic Model
One defining feature of USTC is its uncapped supply. New tokens enter circulation whenever users burn LUNC to mint them. Conversely, when USTC is burned, an equivalent value of LUNC is created.
This circular economic model was designed to balance supply and demand dynamically. However, after the depegging event, this mechanism broke down due to collapsing confidence in LUNC’s value and insufficient arbitrage activity.
Today, USTC circulates independently of active minting or redemption mechanisms. Its market price is determined purely by trading activity across decentralized and centralized exchanges.
Founding Team and Development Background
Terraform Labs was founded in 2018 by Daniel Shin and Do Kwon, combining expertise in fintech, e-commerce, and software engineering.
Daniel Shin, a Wharton School alumnus, had already made a name for himself in Korea’s tech scene before Terra. He founded:
- TMON, one of South Korea’s leading e-commerce platforms
- Fast Track Asia, a startup incubator supporting early-stage ventures
- Chai, a mobile payment app that gained widespread adoption
His vision was to build a decentralized payment network that could rival traditional financial infrastructure—driven by low fees and high scalability.
Do Kwon, a Stanford graduate, brought deep technical experience from his time at Microsoft, where he worked on natural language processing systems. He left to focus full-time on blockchain innovation and quickly became a prominent figure in the crypto space.
In 2019, Do Kwon was named to Forbes’ 30 Under 30 list for his contributions to financial technology.
Funding and Institutional Support
Terra attracted significant investment during its rise:
- Raised $58 million by January 2021
- Secured an additional $150 million in July 2021 during a major funding round
Key investors included top-tier firms such as:
- Pantera Capital
- Galaxy Digital
- Coinbase Ventures
This institutional backing underscored the market’s belief in Terra’s potential to disrupt traditional finance through scalable DeFi applications.
Frequently Asked Questions (FAQ)
Q: What is the difference between UST and USTC?
A: UST was the original name of the TerraUSD stablecoin. After losing its peg in 2022, it was renamed USTC (TerraClassicUSD) and continues to trade on the legacy TerraClassic blockchain.
Q: Is USTC still pegged to the US dollar?
A: No. USTC lost its $1 peg in May 2022 and currently trades at a fraction of that value. It no longer maintains algorithmic stability.
Q: Can I still use USTC for DeFi applications?
A: Limited DeFi activity exists on the TerraClassic chain, but most projects have migrated to Terra 2.0 or other ecosystems. Use caution due to low liquidity and high volatility.
Q: Will USTC ever be revived or re-pegged?
A: There are no official plans from the core team or Terraform Labs to re-peg or upgrade USTC. Any revival would require community-led efforts.
Q: How is USTC different from USDT or USDC?
A: USDT and USDC are backed by real-world assets (like cash or bonds) and managed by centralized companies. USTC was an algorithmic stablecoin relying on code and tokenomics instead of reserves.
Q: Where can I buy USTC today?
A: USTC is available on select centralized and decentralized exchanges. Always verify contract addresses and exchange reputation before trading.

Final Thoughts
TerraClassicUSD (USTC) stands as both a cautionary tale and a landmark experiment in decentralized finance. Its ambitious attempt to create a fully algorithmic, scalable stablecoin captured global attention—and investment—but ultimately collapsed under pressure from market forces and structural vulnerabilities.
Yet, its legacy endures. The ideas pioneered by Terra—cross-chain stable payments, low-cost currency swaps, and community-driven monetary policy—continue to influence next-generation DeFi protocols.
For investors and enthusiasts alike, understanding USTC’s history offers valuable insights into the risks and rewards of innovation in the rapidly evolving world of cryptocurrency.
