CHECKOS — VERIFIED ON-CHAIN WORK
A tiny desktop of on-chain tasks from different protocols, each unlocking rewards when verified. Each window is a task: hold a token, revoke a delegate, keep a fee balance. You do it in your own wallet. Connecting a wallet is optional and never signs or sends anything.
No proof, no reward: every task closes with a public chain read.
How it pays
Paste an address
Open wallet.exe and paste any Solana address. It is checked for format only. Nothing connects.
Open a task
Each task states its rule in plain words and which public read decides it. The sponsor slot is empty in this build.
Do it in your wallet
Bridge, revoke, hold, vote: the action happens in your own wallet, outside this page.
The chain is read
A pass is a successful read of the chain. A pass earns 10 pts, once per address. Every 40 pts is a milestone.
Points rules are this build's own: 10 pts per verified task, each task counts once per address, a milestone every 40 pts.
Paste an address
Read-only. The address is checked for format and used for public reads. Nothing is connected, signed or stored on a server.
Tasks
No proof, no reward: every task closes with a public chain read.

It refuses
No proof, no reward: every task closes with a public chain read.
How a task is verified
Every task is a rule about the chain. The rule is read from a public source: a call to a public Solana RPC. A pass needs a successful read. If the read fails the result is CANNOT CHECK and nothing is counted.
Why it holds up
Counting the verified action honestly is the hard part, and it is the part a clone gets wrong. A task that cannot be told apart from a bot or from a guess is not worth paying for, so it is not offered.
Where rewards come from
Protocols fund quests; the platform takes a cut. The cut funds the rewards pool that pays out. Nothing is funded in this build, and no amounts are shown because none exist.
Fractional shares of real stocks (HOOD, NVDA, AAPL) or stablecoins (USDC, USDT). Names are listed as text. None of it is live: payouts are while payouts are not live and nothing is sent.

FAQ
What is stored?
Only your progress and points balance, in this browser. There is no account and no server-side record. The address you paste is sent only to the two public read sources to run a check.
Are payouts real in this build?
No. Payouts are not live yet. The receipt says "Not live yet · nothing was sent" and shows what would have been sent. No transaction is made.
Do I need a wallet?
To do the tasks, yes: you complete them in your own wallet. To use this page you only paste an address. The Connect Wallet button in the top bar links your Phantom wallet for display only: it never signs or sends anything.
What does CANNOT CHECK mean?
The public read failed or could not see enough history. It is never counted as a pass and never as a fail.
Who pays?
Protocols fund quests and the platform takes a cut. No sponsor is funding anything in this build.
Is this financial advice?
No. Nothing here is financial advice, and stocks or tokens named here are named as text only.
Local-only waitlist. Nothing is sent: your email stays in this browser.
Not financial advice. Wallet connection, payouts and the rewards pool are not live yet.
