• Delegator reward compound: Manual. You can't restake rewards if your pending rewards are less than 50 MATIC.

MATIC staking rewards are not auto-compounded and pending rewards accrue in the contract address, without any on-chain transactions, until a customer materializes the reward. We’ll surface the rewards as “pending rewards” in the Prime UI. The pending reward amount will accrue over time, and only realized on-chain when a customer restakes the rewards or unstakes the wallet.

Rewards accrue in the contract address over time rather than through on chain transactions. Rewards earned will be shown as “pending rewards” and will not have Reward activity in Prime accounts. Pending rewards can be realized on chain by restaking the rewards through a restake transaction or unstaking the wallet.
