After two rounds of rigorous controlled testing, USDFC—the first stablecoin backed by native FIL—will officially open to the public next week. In this article, you will find:
• How the Alpha → Beta timeline unfolds, and why the peg is rock solid.
• How USDFC actually operates (110% collateralization rate),
• The tools you can now leverage, as well as
• Our next step is to make lending simpler.
From Alpha to official release.
USDFC has been operating under controlled conditions for several weeks, with a 24/7 arbitrage bot guarding the peg. After a comprehensive testing program, we are confident the stablecoin is ready for public use.
Alpha — March 2025.
• External security audits and adversarial attack simulations.
• Swap pool deployment and intensive internal 'dogfooding' trades.
• Listed on CoinGecko, DeFiLlama, GLIF Explorer, and other analytical dashboards.
Beta version — From April 2025 to present.
• Vulnerability bounty program: we received 36 reports from 19 white hat participants; no high severity issues found.
• Crypto Econ Lab (CEL) led comprehensive stress testing: liquidation, redemption loops, and extreme scenarios.
• Peg-monitor bot running in real-time for continuous fine-tuning.
Key beta metrics so far.
• SushiSwap trading volume: weekly > 100k USD.
• Cumulative lending limit: > 250k USD.
• USDFC annual yield: 8–10%, targeting iFIL/pFIL collateral, with its own staking yield close to the same range.
Official launch — Next week at FIL Dev Summit 6.
With the peg stabilization, practical testing of code, and real liquidity flowing, we can easily transition to a full public launch. Starting from block 1, every Filecoin wallet will be able to mint, swap, lend, and bridge USDFC.

USDFC in simple English.
1. Lock FIL in the vault.
2. Mint USDFC with a collateralization rate of up to 110%.
3. Redeem at any time by burning USDFC and withdrawing the same FIL.
4. If your ratio falls below 110%, the stability pool will repay debts and liquidate the vault—now our bot will immediately arbitrage this event.
Since users do not need to sell FIL to unlock liquidity, USDFC helps mitigate the extreme price volatility that still characterizes the Filecoin market.
You can now use USDFC.
Swap
SushiSwap V3 is live, allowing exchanges between FIL/USDFC and USDFC/axlUSDC.
Payment
Lighthouse now accepts USDFC as long-term storage fees, marking Filecoin's first true USD checkout.
No slippage exchange.
Filecoin provides native USD liquidity for everyone. Mint ↔ No slippage exchange. FIL holders can mint USDFC as operational costs, then burn tokens to retrieve their original FIL—no off-exchange platforms, no price impact.
In our lending application.
Using liquid-staked FIL for lending, iFIL and pFIL (≈10% staking yield) serve as collateral. Their yields effectively offset 8-10% borrowing costs, creating a balanced market where lenders earn dollar annual interest rates far above the DeFi average.

USDFC will move to any EVM with one click, enabling additional yield strategies on DeFi platforms.
Why high-yield dollars matter.
The Filecoin ecosystem lacks seamless on-chain USD liquidity. USDFC bridges this gap while offering attractive yield conditions. By enabling users to lend rather than sell, it helps stabilize prices; by providing double-digit USD yields and cross-chain transfers in a single hop, it attracts new capital to Filecoin—driving ongoing demand for network growth.
Next steps
Q4 2025
Launch a pool-based lending market alongside the current order book, providing passive users with one-click deposits. A dedicated market-making vault will provide additional liquidity for both lending venues, narrowing spreads and simplifying the lending experience.
