🏦 Yield Vault

Secure, low-risk savings for your crypto

Yield Vault is a crypto savings platform that solves the treasury management problem by providing a simple, bank-like savings account experience for digital assets. Born from the founders' own struggle to confidently allocate their treasury across DeFi protocols, Yield Vault allows users to deposit USDC, ETH, or BTC into risk-managed vaults that automatically diversify across multiple low-risk yield strategies.

🌟 Key Features

• Multi-Asset Support: Deposit USDC, ETH, or BTC into dedicated vaults
• Automated Diversification: Funds are automatically allocated across multiple low-risk yield strategies
• Conservative Yield Strategies:
  • Lending protocols (Aave, Compound)
  • Liquid staking (Lido, Rocket Pool)
  • DEX liquidity provision (Uniswap, Curve)
  • Other conservative DeFi approaches
• ERC-4626 Standard: Built on the robust vault standard for maximum compatibility
• Transparent Risk Management: Comprehensive protocol risk assessments
• Instant Withdrawals: Access your funds whenever needed
• Bank-like UX: User-friendly interface that abstracts DeFi complexity

🎯 Problem We Solve

• Simplified Access: No need to research dozens of protocols
• Risk Mitigation: Professional diversification across vetted strategies
• Operational Efficiency: One interface for all your yield-generating assets
• Peace of Mind: Transparent operations with instant liquidity
