Fiet is a decentralised liquidity commitments protocol that transforms decentralised finance (DeFi) by enabling market makers to provide liquidity to automated market makers (AMMs) without locking funds on-chain. Using cutting-edge zero-knowledge proofs (zkTLS), Fiet verifies liquidity held in banks, exchanges, or wallets, creating deeper, more cost-efficient markets for trading, foreign exchange, and real-world assets.

Fiet empowers secure, capital-efficient markets, reducing trading costs and enabling new opportunities in DeFi.

Why Fiet?

DeFi markets often face liquidity challenges, leading to high slippage and costly trading. Fiet solves this by allowing market makers to commit verified reserve liquidity — funds held off-chain or on-chain without locking them in AMM pools. Through instruments, akin to a hybrid standby letter of credit and warehouse receipt, ensures traders access deep liquidity while market makers retain flexibility.

  • For Traders: Enjoy low-cost, low-slippage trading in markets like local stablecoins (e.g., AUD, BRL) or tokenised RWAs (real estate, private credit, etc.).
  • For Market Makers: Commit dynamic liquidity now, settle later — earning fees without capital lockup or impermanent loss risks.
  • For DeFi Ecosystems: Enable totally new and lower cost liquid markets without bootstrapping retail liquidity with absurd incentives and requiring upfront total value locked (TVL).

How It Works

Fiet integrates traditional finance (TradFi) and DeFi through a simple, secure process:

  1. Liquidity Verification: Market makers use zkTLS to verify reserves in banks or exchanges, ensuring trust without exposing sensitive data.
  2. Liquidity Commitment Certificates (LCCs): Protocol-bound non-transferable tokens represent committed liquidity, traded only in Fiet’s integrated decentralised exchanges (DEXs).
  3. Dynamic Settlements: Liquidity is settled on-chain only when market demand requires it, guided by the Value-to-Signal (VTS) model.
  4. Guaranteed Continuity: Settlement Guarantors step in if market makers fail to deliver, ensuring market stability.

Fiet is built on Arbitrum, with plans for cross-chain expansion, making it accessible across DeFi ecosystems.
