Check the "premium" to see if it is better for you to use an exchange or to redeem. A positive premium means swapping may return more tokens, but be aware of the liquidity available, and the impact your swap will make on your rate.
If you decide to redeem, click the redeem button
Enter the amount of basket tokens you would like to redeem (or click the max button for the maximum amount).
Once you are happy with the amount, click the redeem button and approve the transaction in your wallet.
The basket tokens will be burned and the underlying tokens are withdrawn from the vault, sold and returned as your chosen redemption token.
