# Advanced > Protocol operations that go beyond the standard user flows. Canonical URL: https://docs.polaris.finance/testnet/advanced Markdown URL: https://docs.polaris.finance/testnet/advanced.md Section: Using Polaris Testnet Documentation index: https://docs.polaris.finance/llms.txt Full documentation bundle: https://docs.polaris.finance/llms-full.txt --- The Advanced section brings together protocol operations that go beyond the standard user flows. These tools are primarily intended for arbitrageurs and experienced users who want direct access to core protocol mechanisms. This section currently includes the following operations: - **Mint / Redeem**: Mint or redeem USDp and GOLDp directly against pETH whenever market prices create arbitrage opportunities that help restore the peg. - **SP Direct**: Deposit directly into the Stability Pool instead of the auto-compounding Earn Vault. - **Collateral Auctions** *(currently unavailable)* When a savings vault absorbs a liquidation, you can purchase pETH collateral from permissionless liquidation auctions. Most auctions are expected to be cleared by keeper bots, but anyone can participate. - **Conversions**: Convert pETH into POLAR directly through the protocol conversion mechanism.
