Terms, straight
Pooled sKAITO sits in the operator's wallet (the one holding the Kaito NFT). A contract can pull it only for redemptions, but the operator holds the keys and could revoke that permission or move the tokens. You are trusting the operator. The vault publishes solvency and live redemption capacity onchain so you can check instead of ask.
The fee comes out of the boost only, never base rewards. Non-referred: 80% of your attributable boost compounds into the rate, 20% is the operator fee. Referred: 85% to you, 5% to your referrer, 10% to the operator. Base staking rewards compound in full. If Kaito ever reduces the boost to zero, your worst case is earning what self-staking pays.
Linking your own second wallet to your own code is against these terms. It cannot be technically prevented and we will not pretend otherwise, but obvious sybil patterns can have their referral bonuses withheld before a root is published. Base pool earnings are never touched.
Kaito's own terms let them change eligibility rules or disqualify participants before distributions, their staking contract admin can freeze addresses, and no official source documents whether the boost caps at any balance. Any of these can shrink or end the boost. The public redemption rate will show it if it happens.
Campaign rewards vest on their own schedules and arrive as partner tokens that get swapped to sKAITO. The rate climbs in steps, sometimes nothing for weeks, then a jump. Referral bonuses follow the same cadence via Merkle roots.
