Harmony Yield Boost

Built on the ERC-4626 tokenized vault standard (used by Yearn V3 and other leading protocols), Yield Boost delivers additional yields for 1sDAI holders through automated compounding.

Native sDAI Yield (MakerDAO's DSR via bridged 1sDAI)

Treasury-Boosted Returns (Strategic allocations from treasury yield)

Overview

Key Features

• 🚀 Enhanced APY through yield boosting
• ✅ Zero effort, auto-compounding
• ⚡ Instant deposits and withdrawals
• 🔒 No lock-up periods
• 💰 No minimum deposit requirements

Technical Details

Exchange Rate Mechanism

The core of the yield boost system is based on an exchange rate mechanism:

• Initial rate: 1 boostDAI = 1 1sDAI
• The exchange rate increases over time, generating yield
• Users maintain a constant boostDAI balance while its 1sDAI value grows
• Current APY: 11.8%

Fees

• Deposit Fee: 0.1%
• Withdrawal Fee: 0.1%

Smart Contract Integration

The protocol implements the ERC-4626 Tokenized Vault Standard and integrates with:

• Sky Protocol (MakerDAO) for 1sDAI
• Harmony blockchain for transactions
• Treasury system for additional yield strategies
