FRAX vs DAI (2026)

Where FRAX and DAI actually differ

The table above is the short version. Each row is a design decision with consequences, and the rows that matter most are the ones describing what happens when something goes wrong rather than what the protocol does on a normal day.

DAI remains the decentralised stablecoin benchmark; FRAX evolved toward full collateralisation with a broader Frax ecosystem.

How to compare two stablecoins

Every stablecoin quotes at a dollar in calm markets, so the quote tells you nothing. What distinguishes them is the mechanism holding the peg and what that mechanism does when it is tested — and those differ far more than the shared $1.00 suggests.

• Backing. Cash and Treasuries with a custodian, crypto collateral in over-collateralised positions, or a hedged derivatives position. Each fails in different conditions.
• Redemption. Who can redeem at par, in what size, and how quickly. A peg defended only by secondary market trading is weaker than one defended by redemption.
• Depeg history. Whether it has broken before, how far, and whether it recovered on its own or because someone stepped in.
• Censorship surface. Whether the issuer can freeze addresses. A feature for compliance, a risk if you assumed the asset was unseizable.
• Yield source, where it pays yield. Reserve interest, borrower demand and funding-rate capture are three different risks wearing the same label.

What goes wrong with either choice

• Depeg. A stablecoin at $0.97 has lost 3% of principal, and some breaks have been permanent.
• Reserve or counterparty failure for fiat-backed designs — custodian, bank, or redemption policy.
• Collateral and liquidation failure for crypto-backed designs during fast moves.
• Regulatory action, including address freezes on centralised issuers.
• Contagion: stablecoins are collateral throughout DeFi, so a break propagates well beyond its holders.
