  • PancakeSwap code dispute – Curve flagged unauthorized use of StableSwap code

FastBridge: Instant L2-to-Ethereum crvUSD Transfers

The biggest infrastructure release of the month was FastBridge, which removes the seven-day withdrawal delay for crvUSD bridging from L2 networks back to Ethereum.

Using LayerZero cross-chain messaging combined with canonical bridge settlement, FastBridge enables crvUSD to move from Arbitrum, Optimism, or Fraxtal to Ethereum in roughly 15 minutes. An Ethereum-side vault releases pre-minted crvUSD upon receiving the LayerZero confirmation, while the canonical bridge settles in the background and replenishes the vault.

This is critical infrastructure for cross-chain peg stability. When L2 prices drift from mainnet, arbitrageurs can now respond immediately rather than waiting a week which helps keeping crvUSD closer to mainnet peg everywhere.

Safety mechanisms include debt ceilings per vault, daily bridge limits per L2, minimum bridge amounts, and an Emergency DAO kill switch.

FastBridge: Bringing Fast L2 Withdrawals to crvUSD
FastBridge removes the seven-day withdrawal delay for crvUSD bridging from L2 networks to Ethereum. Using LayerZero messaging and a vault-based design, it enables very fast transfers while preserving canonical bridge security and strengthening the crvUSD peg across chains.

GHO PegKeeper: Curve x Aave Integration

Governance approved the creation of a new crvUSD PegKeeper for Aave's GHO stablecoin (Vote 1358), with a 3M crvUSD debt ceiling.

This initiates another cross-protocol milestone, linking crvUSD's peg defense infrastructure directly with Aave's GHO stablecoin liquidity. The PegKeeper can mint and deposit crvUSD into GHO/crvUSD pools to support peg stability for crvUSD.

crvUSD Borrow Rate Easing

Following the monetary policy changes introduced in January and the peg defense measures from February, March saw further easing of crvUSD borrow rates through Vote 1364 in order for the markets to stay competitive within DeFi.

Average borrow rates declined from ~11.1% at the start of the month to ~5.6% by month end, making crvUSD minting significantly more attractive. The peg remained stable throughout, trading between $0.9993 and $1.0000.

Curve Knowledge Hub

All Curve documentation was unified into a single platform at docs.curve.finance with the launch of the Curve Knowledge Hub.

The Hub consolidates user guides, developer references, protocol explanations, and a new "Build on Curve" section into one searchable destination. Key features include:

  • Algolia-powered search with AI enhancements for natural language queries
  • MCP integration for AI-assisted development workflows
  • Ecosystem news from news.curve.finance integrated directly
  • Beginner-friendly onboarding guides for users new to DeFi
Curve Knowledge Hub: A Unified Home for Curve Documentation
The Curve Knowledge Hub unifies all Curve documentation into a single, searchable platform at docs.curve.finance. Designed for users, developers, and protocols alike, it serves as the new source of truth for understanding, using, and building on Curve.

FXSwap Simulations: Behind the Scenes

A detailed article and video were published explaining how Curve uses large-scale backtesting simulations to optimize FXSwap pool parameters before deployment. Millions of parameter combinations are tested against years of historical price data to find configurations that minimize slippage, maintain pool balance, and maximize profitability.

FXSwap pools are already live on YieldBasis (BTC/crvUSD, ETH/crvUSD) and several FX pilot pools (CHF, GBP, BRZ, IDR). The publication increases transparency into Curve's AMM design process and provides a framework for asset issuers considering on-chain FX liquidity.

PancakeSwap Code Dispute

Curve publicly flagged that PancakeSwap's "Infinity StableSwap" upgrade appeared to use Curve's StableSwap code without proper licensing. PancakeSwap acknowledged the concern and indicated willingness to engage. Curve signaled a collaborative resolution, noting it is "better to be friends and build together."

crvUSD Flashloan Cap Raised: 3M -> 30M

Governance approved Vote 1355, raising the crvUSD flashloan cap 10x from 3M to 30M crvUSD. The higher ceiling expands headroom for arbitrage, liquidations, and integrations that rely on flashloan-based routing through crvUSD, supporting deeper market efficiency around the peg without requiring locked-up capital.

Curve at Stable Summit IV

Stable Summit IV this year took place in Cannes with Curve as one of the main sponsors again. Curve contributors delivered several talks:
