What does 'policy state' refer to in this context? Does it indicate whether a policy has been enforced in a specific smart session? I'm referring to the Policy section in the ModuleSDK documentation and the ModuleSDK source code to understand policies. Are there additional resources or references I should review?

[kopy-kat]

so the policy state refers to the configuration of the policies, which are held in state/storage. these policies are in this pr

I think the specific helpers that would be useful are

• getPolicyData from ERC20SpendingLimitPolicy
• getTimeFrameConfig from TimeFramePolicy
• actionConfigs from UniActionPolicy
• usageLimitConfigs from UsageLimitPolicy
• valueLimitConfigs from ValueLimitPolicy

these should be in the form of getter functions like this one. in terms of structure, these should be in the usage.ts file of the relevant policy in the policies section

lmk if anything else is unclear on this

For ERC20SpendingLimitPolicy, should I write the code for the helper based on the current state of the contract as seen here or do you want me to write it based on the state of the contract as it is in the PR that you have mentioned?

[Dhruv-Mishra]

Also, I noticed that the policy contracts are not deployed on Ethereum mainnet. Are they deployed on any other chain? Where can I test them?
Edit: Found the contract on Eth Sepolia, so will write tests accordingly

[kopy-kat]

based on the prs for all of them - will deploy the remaining ones from the pr to eth sepolia tomorrow

[kopy-kat]

here are the updated contracts on sepolia:

• erc20 spending limit: 0xbeF80abb8cAEEf28A9B252DcEb7DC508647128f9
• uni action policy: 0x081C52B15BE96D6A1C729B0a34c8B4bef3da9238

[Dhruv-Mishra]

based on the prs for all of them - will deploy the remaining ones from the pr to eth sepolia tomorrow

Alright, will proceed with that

@kopy-kat can you elaborate on the 2nd(toConfigId helper) and 3rd(action policy fallback constants) requirements here

[kopy-kat]

3 is very easy its just constants for these flags: https://github.com/erc7579/smartsessions/blob/4f8481f91cb30f96a8ee04188415363128eda0fb/contracts/DataTypes.sol#L197-L198

for 2, the policies you integrated take in a configId for the view functions which is different to permissionId. its a bit complicated since depending on the policy type it works a bit differently, see here: https://github.com/erc7579/smartsessions/blob/4f8481f91cb30f96a8ee04188415363128eda0fb/contracts/lib/IdLib.sol#L37-L71. but I think we'd want to have a helper where you pass the permission id and policy type and then it gets you the right config id
