# Remove Liquidity Guide

Balancer v3 supports several different types of remove liquidity operationsopen in new window

# Core Concepts

The core concepts of removing liquidity are the same for any programming language or framework:

• When removing liquidity the user sends Balancer Pool Tokens (BPTs), and will receive pool tokens
• Use a permit signature to approve the Router to spend BPT
• Token amount inputs/outputs are always in the raw token scale, e.g. 1 USDC should be sent as 1000000 because it has 6 decimals
• If a pool's tokens include an ERC4626 with an initialized buffer, you have the option to receive the asset() of the ERC4626 when removing liquidity.
• Transactions are always sent to a Router
  • Use the standard Router to receive standard pool tokens
  • Use the CompositeLiquidityRouter to receive a pool's underlying tokens
