# Tokens rebalancing

The goal of this function is to rebalance a three-token portfolio to reach specific target weights (measured in basis points), using USD valuations and slippage-protected swaps.

For example, suppose the targets are:

* 50% BTC
* 30% ETH
* 20% DAI

If the portfolio currently holds:

* $6,500 in BTC (65%)
* $2,500 in ETH (25%)
* $1,000 in DAI (10%)

Since BTC is overweight while ETH and DAI are underweight, the function will swap $500 worth of BTC into ETH and $1,000 worth of BTC into DAI to restore the target balance.
