The system is composed of two main modules: iAsset and PoEL.

dApps that hold iAssets (e.g., liquidity pools) and need to withdraw rewards periodically can use the following methods from the PoEL and iAsset modules.

Methods Used During Integration

Method	In / out	Comment
View method get_user_rewards (user_address: address): UserRewardsInfo	in user_address: address of the iasset holder out UserRewardsInfo result object with various details. Fields: Allocated rewards for a user allocated_rewards: u64, Withdrawable (claimed) rewards for a user withdrawable_rewards: u64, Epoch when rewards were claimed (moved to withdrawable) withdrawable_rewards_epoch: u64, Timestamp when rewards were claimed (moved to withdrawable) withdrawable_rewards_ts: u64, Withdrawn rewards for a user withdrawn_rewards: u64	Method returns total allocated rewards, withdrawable, withdrawn etc
View method get_allocatable_rewards (user_address: address, asset: Object<Metadata>): u64	in user_address: address of the iasset holder asset : iasset object out amount of supra coins	Return number of rewards could be allocated by calling method update_rewards
View method get_withdraw_timer_for_user (user_address: address): u64	in user_address: address of the iasset holder	Method is useful for the claim/withdraw scenario. This method indicates the remaining time to wait until withdraw_rewards can be invoked

PoEL Module

Method	In / out	Comment
update_rewards(account: &signer, asset: Object)	in account: signer, who updates the rewards asset : iasset object, for which rewards has to be updated	Call this method whenever get_allocatable_rewards returns a non-zero value
claim_rewards(account: &signer)	in account: signer, who claims already allocated rewards	Call this method only when allocated_reward>0
withdraw_rewards(account: &signer)	in account: signer, who withdraw already claimed rewards	Method can be called if withdrawable_rewards not 0 (something claimed) and Get_withdraw_timer_for_user is 0
