official Algebra Integral v1.2 IAlgebraPoolState plugin can be changed setPlugin remove plugin documentation
💡 Result:
<search_synthesis>
In Algebra Integral v1.2, the plugin associated with a pool can be changed or replaced at any time [1][2]. This action is handled by invoking the setPlugin method directly on the liquidity pool contract or through a designated entry point [3][1][4]. Key details regarding plugin management include: Permissions: Plugin replacement is a sensitive, permissioned action [1][2]. It can only be executed by an address with the appropriate rights, typically the owner of the Algebra Factory or the owner of the POOLS_ADMINISTRATOR role [1][2]. When using custom pool entry points, this is managed via the setPlugin(address pool, address newPluginAddress) method, which checks that the caller is the authorized custom deployer for that specific pool [3][4]. Security Considerations: Because replacing a plugin fundamentally alters the logic and behavior of the liquidity pool, it is strongly recommended that this capability be controlled with high-security measures [1][2]. The documentation advises using multi-sig accounts and implementing granular access rights to prevent malicious or unauthorized changes that could negatively impact users [1][2]. Plugin Interface: The IAlgebraPoolState interface, which governs the pool's state, includes a plugin() method that returns the address of the currently used plugin [5]. The documentation explicitly notes that the plugin is subject to change [5]. For developers building custom plugins, the management functions (such as setPlugin, setPluginConfig, and setFee) are typically implemented in an AlgebraCustomPoolEntryPoint contract or a similar factory/manager structure, which acts as the authorized interface for pool management [3][4].

Refresh plugin addresses after configuration changes.
Algebra allows a pool plugin to be detached or replaced. updatePluginFees calls plugin() only while pool.plugin is undefined, so retained pools continue querying the old plugin after a replacement. A removed plugin is also not detected because the cached nonzero address remains in pool.plugin. The previous plugin-derived pool.fee can therefore remain until another fee update occurs.
Re-read plugin() for retained pools, or invalidate the cached address when the pool changes its plugin. If the new address is zero, restore pool.fee from the pool's current static fee.
