Stake with KTON

How the numbers are calculated

A staked Gram earns once per validation round, about 241 times a year. The calculator assumes the chosen APY holds and compounds every round, which works out to end = amount × (1 + APY)^(years).

KTON, last 30 days (net) is the annualized growth of the KTON exchange rate between a block 30 days ago and the latest block, after the 16% fee. Network gross is the reward of the last completed round before any fee, which only a validator would receive in full.

APY vs APR, gross vs net

TermMeaning
APRSimple yearly rate, no compounding
APYYearly rate including compounding; a bit higher than APR for the same rewards
GrossBefore the protocol’s fee
NetWhat holders keep after the fee

When comparing protocols, compare a net APY with a net APY measured over a similar window. A gross figure can look several points better and describe the same rewards.

Frequently asked questions

Can I earn interest on Toncoin?
Yes. Toncoin, now called Gram, earns through staking rather than bank-style interest: validators are paid every round and staking protocols pass that reward on. Over the last 30 days TON liquid staking paid up to 17.1% a year after fees, measured on-chain (all rates). The calculator above shows what that means for your amount.
How much will 1,000 Gram earn in a year?
At the recent KTON rate of 13.6% net, about 1,000 × 13.6% Gram, if the rate holds. Use the calculator above for other amounts and periods.
Are rewards paid in Gram?
With KTON, rewards raise the Gram value of each KTON. You realize them in Gram when you unstake.
