fUSD v3

A Fuse native stablecoin
The latest upgrade to our Fuse native stablecoin, addresses the challenges of liquidity fragmentation and systemic risks associated with stablecoins. It is a USD-pegged token backed by the two most popular stablecoins by volume: USDT v2 and USDC v2.

Technical Innovations in Minting/redeeming

  • Dynamic Weight System: The pool now operates with a minimum of 10% and a maximum of 65% for either underlying asset.
  • Pool Equilibrium: To ensure stability, minting/redeeming rates consider the pool weights. Transactions that risk unbalancing the pool will not be processed.

Migrate to fUSD v3 (fUSD v2 Holders)

The migration process from fUSD v2 to fUSD v3 is straightforward:
  1. 1.
    Remove any existing liquidity from fUSD v2 or pools involving fUSD v2.
  2. 2.
    Swap USDT v1 and USDC v1 for their v2 counterparts.
  3. 3.
    Add liquidity to fUSD v3 with USDC v2 and USDT v2 in the newly flexible ratio.

Minting fUSD v3


Minting fUSD v3 offers more flexibility compared to the previous version:
  • Single Mint: Get fUSD v3 by minting it with either USDC v2 or USDT v2.
  • Multi Mint: Provide USDC v2 and USDT v2 to mint fUSD v3. The updated process allows for different amounts of each asset.

Redeeming fUSD v3

Redeeming fUSD involves exchanging fUSD for an equivalent amount of underlying pool assets (USDC v2 or USDT v2) or both.
When users interact with the pool, the system automatically checks for equilibrium within these set parameters. If a redeeming transaction threatens to disrupt the pool's balance, it won't be processed, and the UI will prompt the user to adjust their asset ratio.
For instance, the transaction will be halted if a user wants to redeem fUSD for USDC but the pool's current USDC allocation is already at the 65% maximum. The user will then need to adjust their redemption request, perhaps by opting for USDT v2 or modifying the USDC v2 amount to align with the pool's current parameters.

  6. 6.

Depeg Protocol

In case of a depeg event, the isolateAsset function isolates the affected asset, putting the pool in depeg mode. This restricts swapping and adding liquidity, permitting only the withdrawal of balanced liquidity for security reasons.
