Your balance never changes
vATOM is non-rebasing. You keep the same number of tokens; each one becomes redeemable for more ATOM as staking rewards compound. The exchange rate moves, not your balance.
Stake ATOM, keep a token you can use. No bridge, no interchain accounts — the contract stakes on the same chain it lives on.
New to vATOM? Read what it is and then the exchange rate — those two pages explain every number the app shows you.
About to redeem? Read redeeming takes 21 days first. The redemption flow has four stages and the app cannot tell you your exact payout until the third one. That surprises people, so it is worth five minutes.
Running a deployment? The operator runbooks live in docs/operations/ in the repository, not on this site. What everyone else needs to know about them is keeping it running.
Testnet
This deployment is on a testnet, so the tokens have no value and you can try everything without risking anything. Risks covers what holding vATOM involves, including the open items before a mainnet deployment.
