High APY ≠ profit.
Subnet staking pays you in that subnet's alpha token. If alpha falls against TAO, you can earn rewards and still end up with less TAO. This calculator shows what you'd actually walk away with.
How it works, in plain English
Root staking (subnet 0) — you stake TAO and are paid in TAO. No alpha price risk, usually lower yield.
Subnet staking — your TAO is swapped into the subnet's alpha through a pool. Rewards are paid in alpha. When you leave, alpha is swapped back to TAO at whatever the price is then.
Slippage — each subnet pool is a constant-product AMM (TAO × alpha = k). Big trades in small pools move the price against you, on the way in and out.
FAQ
Is subnet staking APY real profit?
Only in alpha terms. Your profit in TAO depends on the alpha/TAO price when you unstake. A 60% APY with a 50% alpha drop is still a loss.
What's the difference between root and subnet staking?
Root stakes TAO and earns TAO from a share of all subnets' validator emissions. Subnet staking holds alpha and earns alpha from one subnet.
How is the APY estimated?
From on-chain data: alpha emitted per block × ~41% validator/staker share × (1 − root proportion) × (1 − validator take), annualised over ~7,200 blocks/day, divided by alpha outstanding. Root APY uses the root proportion of each subnet's validator emissions, valued at the pool price, divided by total root stake. These are rough estimates; real yields vary by validator and change every block.
How is slippage calculated?
Using the pool's TAO and alpha reserves with x·y=k math. Exit slippage is computed after the pool price moves to your chosen scenario.
Where does the data come from?
Directly from the Bittensor Finney chain via the public OpenTensor RPC — see the "as of" note above the results.
