Terms of Service

1What Proof of Stake is

Proof of Stake is a launchpad on Solana. Coins launched here are created on pump.fun, a third-party venue we do not operate, and trade in its pools. Every trade on pump.fun pays a creator fee. For coins launched here, all of that creator fee is routed to a staking pool for the coin and paid out in SOL to the people who stake the coin. Neither the coin's launcher nor we take any share of it.

The staking pool is a program (“fee_stake”) on Solana. Anyone can trigger most of its steps (closing a window, activating a deposit, paying out, returning tokens after the delay) and we run a service (“the crank”) that does so on a schedule so that nobody has to.

There are two ways to stake, into the same pool and for the same share. With a connected wallet, you sign the stake, and later the unstake and the withdrawal, yourself: none of it depends on us. Without connecting anything, you send the coin to the coin's staking address from a wallet you control, and send 0.01 SOL to that same address from that same wallet to leave: in that case one step is done by a key we hold, which reads who sent the transfer and tells the program (section 4).

Almost everything here happens on chain. Section 4 names every place where one of our keys is involved, because that distinction is the one that matters if something goes wrong.

2We are not your adviser

Nothing here is investment, financial, legal, or tax advice, or a recommendation to buy, sell, hold or stake anything. Not the listings, the charts, the market caps, the “paid to stakers” figures, the estimates of your share of a window, or anything we or anyone else writes on the site. We are not your broker, adviser, or fiduciary, and using the platform does not make us one.

3Trading is yours, and it is final

When you buy, sell, stake, unstake, claim or launch from this site with a connected wallet, the transaction is built in your browser, simulated, shown to you, and signed by your wallet. We never hold your keys. Buying and selling happen on pump.fun's programs; we are not a party to those trades. A confirmed transaction cannot be reversed by anyone, including us.

A transfer to a staking address is final. Tokens sent from a wallet you do not control (an exchange, a custodial service) are credited to that wallet, not to you. SOL sent to a staking address is not refunded: up to the exit fee goes to the platform when it starts an exit, the rest is shared between the pool's stakers. A token that is not the pool's coin, sent there by mistake, can be sent back by the program's admin to an account of the same token; we will try on request but promise nothing.

We cannot recover funds sent to a wrong address, signed into a phishing site, or lost to a compromised wallet or extension. Check every address and every transaction before approving it. Your keys and seed phrase are entirely your responsibility.

4Where our keys are involved

We would rather name every place our keys touch the flow than have you discover them. These addresses are published on the docs page and you can watch every transaction they make.

None of this makes us a bank, exchange, custodian, or deposit-taker. We do not hold an account balance for you, there is nothing to withdraw from us, and outside the flows above your assets never touch anything we control.

5Fees

pump.fun charges a fee on every trade of every coin, part of which is a creator fee. Those rates are set by pump.fun, shown before you trade, and are not ours to change. For coins launched here, the whole creator fee goes to the coin's staking pool, fixed forever. Neither the launcher nor we take anything from it.

We charge a flat fee to launch a coin and a flat fee to leave a pool, both shown before you sign and capped in the program (section 4). Staking, payouts and claiming cost nothing beyond Solana's network fees. If you leave by sending 0.01 SOL to the staking address, that transfer is the fee; anything you send above it stays in the pool for the other stakers.

Opening a position costs a small account rent on Solana, paid by you when you stake with a wallet and by the crank when you stake by transfer; it is returned to whoever paid it when the position is closed. You pay Solana network fees on what you sign. Payouts pushed by the crank each carry their share of the network fee of the transaction that sends them (at most 0.000005 SOL in total per transaction).

Coins launched elsewhere, or whose fee split is not the locked one, are not covered by any of this. The site marks a coin whose split no longer points at its pool and removes it from the listings; staking such a coin earns nothing.

6Rewards and what they are not

The pool pays SOL to stakers. Read this section carefully, because it defines what that is and is not.

Payouts are a mechanical feature of how the software works: fees received by the pool during a window are divided, at the close of that window, between the tokens that were staked for the whole window. They are not an investment product, a dividend in the corporate sense, a yield product, or a security. Staking gives you no contractual right to any payment, any amount, or any rate.

Figures on this site describing what has been paid, including “paid in 24 h”, “% per day” and the earnings simulator, are computed from the past. They are not a promise, a projection, or a basis for expecting anything in future. A coin nobody trades pays nothing. A high figure usually means a small pool or a burst of trading, and both change within minutes.

Payouts depend on pump.fun continuing to route creator fees (including after a coin graduates to PumpSwap), on Solana processing transactions, on the crank or someone else running the steps, and on software that has had and will have bugs. Amounts can be delayed, and small amounts accumulate until they are worth a transaction to send. Fees received by a pool during a window in which nothing was staked for the whole window roll into the next one.

Holding or staking the platform's own coin gives no right to the platform's revenue, to a say in how it is run, or to anything from us. What we choose to send to its pool is paid like any other fee, to whoever stakes it at that moment.

If you are staking because you expect to profit from our efforts in running this, do not stake.

7Staking, the staking address and unstaking

8What “locked” means

A coin shown as “locked” has its pump.fun creator set to a program address with no private key, and its fee split written, with pump.fun's update_fee_shares_v2, as 100 % to the coin's pool and nobody else. That instruction revokes the split's admin (admin_revoked) in the same step. From then on pump.fun's own program refuses any change: not the launcher, not us, not anyone.

Only coins in that state are listed and accept stakers. A coin whose split is not locked yet, or no longer points at its pool, can still be opened by its address but refuses deposits.

pump.fun operates its own programs and keeps administrative powers over them (for example over coin creators and “community takeovers”). We do not control those, and they apply to every coin on pump.fun.

9Listings, and what we can do about them

Anyone can launch here. We do not vet, audit, or endorse coins, creators, or anything they claim, and a listing is not evidence that something is genuine or safe. Scams, impersonation and rug pulls are known risks of permissionless launch platforms. Verify independently.

We reserve the right to hide or remove any listing, refuse any launch, and stop the crank from serving any pool, at our discretion — particularly for suspected fraud, impersonation, manipulation, or legal risk. Hiding a listing removes nothing from the blockchain, and the pool keeps working for anyone who runs the steps themselves.

10Your content

When you launch a coin you supply its name, ticker, image, description and links. You grant us a worldwide, royalty-free licence to display, reproduce and distribute that content in operating and promoting the platform. You promise you hold the rights to it, and that it does not impersonate any person or organisation or infringe anyone's trademark, copyright or other rights.

11What you cannot do

Do not use Proof of Stake to break the law. Do not manipulate markets, including wash trading and launching coins designed to deceive buyers. Do not attack, probe, or attempt to exploit the platform, the program, the crank, or their integrations. Do not use it to evade sanctions or launder money. We can restrict or terminate access to the site for any of this without warning you first; the program itself cannot be switched off for anyone.

12Eligibility

You may use Proof of Stake only if you are of legal age where you live and only where doing so is lawful. You may not use it if you are located in, incorporated in, or resident in a jurisdiction subject to comprehensive sanctions, or if you appear on a sanctions or restricted-party list. We may restrict access from any jurisdiction at any time.

Whether any of this is lawful for you — including whether a coin, a stake or a payout is treated as a security or a regulated product where you live — depends on where you are, and knowing that is your responsibility.

13Risks

Coins launched here, especially new ones, can be extremely volatile and illiquid. Prices can go to zero quickly, without warning and without recovery. Thin liquidity means small trades can move prices violently. Staked tokens cannot be sold for the hour it takes to unstake, however the price moves meanwhile. Only risk what you can afford to lose entirely.

The platform depends on infrastructure we do not control: Solana, pump.fun, RPC providers and the browser wallet you use. Any of them can have bugs, exploits, outages, or errors, and so can we. Prices, charts and figures shown here can be delayed or wrong. Do not trade on them as though they were guaranteed accurate.

14Disclaimers and limits on our liability

The platform and everything on it is provided “as is” and “as available”, without warranties of any kind, express, implied or statutory, including merchantability, fitness for a particular purpose, and accuracy.

To the fullest extent the law allows, we accept no liability arising from the platform or anything launched, traded, staked, or paid out on it — including lost funds, lost profits, lost data, and indirect, incidental, special, consequential or punitive damages — however caused, even if we were told it was possible.

Some jurisdictions do not allow some of these exclusions, so parts of this may not apply to you. Nothing here excludes liability that cannot legally be excluded, including for fraud or wilful misconduct, or limits a consumer right the law says cannot be waived.

15Indemnity

If we are sued or fined because of your coin, your content, your trading, or your breach of these terms or the law, you will defend us and cover the losses and reasonable legal costs. “Us” includes our entity, operators, employees and contributors.

16Changes to these terms

When these change we will update the date at the top, and for material changes we will post a notice on the site. Changes apply from when they are posted and are not retroactive. If you keep using the platform after a change takes effect, the new terms apply to you. If you do not agree with one, stop using the platform. The program on chain is not changed by a change to these terms.

17The rest

If part of these terms is unenforceable, the rest stands. Not enforcing a term is not waiving it. You cannot assign these terms; we can, to a successor of the platform. Sections 4 to 8, 14 and 15 survive termination. These terms are the whole agreement between us about the platform.
