Tangent Opens Pre-Deposits Next Week with frxUSD as Default Stablecoin

**frxUSD caps on Aave V4 are set to double** following a proposal from LlamaRisk. The stablecoin's initial $10M limit filled quickly after incentives launched last week, prompting the proposed increase to $20M. **Key developments:** - frxUSD would become the largest stablecoin by cap on Aave V4 if approved - Currently ranks as third most borrowed stablecoin on the platform, behind USDC and USDT - Borrowing rates start at 1.5% APY The rapid cap fill demonstrates demand for frxUSD in the lending market. The proposal reflects Aave V4's security-first approach, gradually expanding limits as the protocol proves stable.

**Tangent, a new DeFi protocol, has officially launched with frxUSD as its core default stablecoin.** The protocol offers liquidity providers up to **30% APR plus future $TAN token allocations** through its PegKeeper pool integration with Curve Finance. Unlike other stablecoins that only use frxUSD for secondary market liquidity, Tangent's USG stablecoin relies on frxUSD as its primary mechanism for maintaining its peg. This launch follows a pre-deposit phase where frxUSD was selected as one of only two default stablecoins (alongside USDC) to secure $TAN allocations.

Frax, Curve, Polygon, and DFB have launched onchain foreign exchange markets on Polygon, pairing frxUSD with five non-USD stablecoins. **Available Trading Pairs:** - BRZ (Brazilian Real) - tGBP (British Pound) - AUDF (Australian Dollar) - KRWQ (Korean Won) - IDRX (Indonesian Rupiah) - frxUSD-USDT0 (dollar liquidity) The collaboration addresses traditional FX market limitations including high fees and fragmented liquidity. DFB provides market-making services while incentives are currently active. [Access pools](https://www.curve.finance/dex/polygon/pools?search=frxusd&sort=-tvl)
