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

MethodIn / OutComment
View method

get_user_rewards

(user_address: address): UserRewardsInfo		in

user_address:
address of the iasset holder

out
UserRewardsInfo object containing:

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  • • Withdrawn rewards for a user withdrawn_rewards: u64
Method returns total allocated rewards, withdrawable, withdrawn etc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:

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
