Boosted Pools

Boosted Pools represent a significant evolution in DeFi yield generation, combining the benefits of DEX liquidity provision and lending market yields in a single position. These pools maximize capital efficiency while maintaining a simple, passive user experience.

Overview

Boosted Pools in Balancer v3 enable:

  • 100% utilization of pool liquidity in lending markets
  • Simultaneous earning from swap fees and lending yields
  • Gas-efficient swaps through an innovative buffer system
  • Simple UX with permissionless entry and exit

Boosted Pool Overview

How Boosted Pools Work

Architecture

Boosted Pools deploy 100% of liquidity into yield-generating strategies (e.g., Aave) while maintaining full swap functionality through a buffer system:

  1. Underlying Assets: Users deposit base assets (e.g., USDC, DAI)
  2. Yield Generation: Assets are automatically converted to yield-bearing tokens (e.g., aUSDC, aDAI)
  3. Buffer System: Facilitates efficient swaps between base assets

Buffer Mechanism

Buffers are simple two-token systems that:

  • Hold small amounts of both base and yield-bearing tokens
  • Enable gas-efficient swaps without external calls for most transactions
  • Automatically rebalance when needed for larger swaps

Key Benefits

For Liquidity Providers:

  • Earn both swap fees and lending yields
  • Simplified position management
  • Permissionless entry and exit
  • Full exposure to yield-bearing assets

For Traders:

  • Seamless swaps between base assets
  • Gas-efficient transactions
  • Deep, reliable liquidity
  • No additional complexity

Implementation

Boosted Pools in v3 improve upon previous versions by:

  • Eliminating nested pool structures
  • Introducing efficient buffer mechanics
  • Optimizing gas costs for all operations
  • Maintaining 100% capital efficiency

Security

Buffers implement simple, limited logic adjacent to the vault, significantly reducing potential security risks compared to previous implementations.

Use Cases

Boosted Pools are ideal for:

  • Stablecoin liquidity provision
  • Passive yield optimization strategies
  • High-volume trading pairs
  • Long-term liquidity deployment
