- Live APY & profit tracking — Vault yield data (1d/7d/30d) and unrealized profit from Yo Protocol API
- USD progress tracking — Target progress based on real-time asset prices via DeFiLlama
- Multi-auth login — Email, Google, Twitter, Discord, Farcaster, or external wallets (MetaMask, Coinbase, etc.)
- Smart wallet support — Coinbase Smart Wallet with account abstraction
- Risk quiz — AI-assisted strategy recommendation based on a quick risk assessment quiz

Nestora uses Privy for flexible authentication:
| Method | Wallet | Flow |
|---|---|---|
| Embedded (Privy) | OTP verification | |
| Google, Twitter, Discord | Embedded (Privy) | OAuth redirect |
| Farcaster | Embedded (Privy) | Sign-In with Farcaster (SIWF) |
| MetaMask, Rabby, etc. | External (browser) | Sign-In with Ethereum (SIWE) |
| Coinbase Smart Wallet | Smart account | Account abstraction via Coinbase SDK |
External wallets are auto-detected via EIP-6963 and reconnected across page refreshes.
| Strategy | Asset | Vault | Risk | Best for |
|---|---|---|---|---|
| Savings | USDC | yoUSD | Low | Emergency funds, short-term savings |
| Growth | cbBTC | yoBTC | Medium | Long-term Bitcoin believers |
| High Growth | WETH | yoETH | High | Experienced investors, long horizon |
All vaults are ERC-4626 compliant, powered by Yo Protocol. Deposits and withdrawals go through the Yo Gateway contract.
This is an experimental DeFi application. Funds deposited into vaults are subject to:
- Smart contract risk — Yo Protocol vault contracts could contain bugs or be exploited
- Market risk — ETH and BTC strategies are exposed to asset price volatility
- Protocol risk — Underlying yield sources (lending, staking) carry their own risks
- Bridge/routing risk — Enso zap transactions route through third-party DEXs
- No deposit insurance — This is not a bank. There is no FDIC or equivalent protection
Use at your own risk. Only deposit what you can afford to lose.
