Economics & launch
Launch a coin
Pick a launchpad — pump.fun on Solana (pay in SOL) or pons on Robinhood Chain (pay in ETH) — then fund a one-time launch address, which launches the coin. No wallet connection required. No sign-up: only sers sign up. What the launcher gets and doesn’t, quotes, custody, the refund wallet, refunds and statuses, side by side for both.

How the launch page works
The launch page is one panel: a row of launchpad chips — pump.fun on Solana and pons on Robinhood Chain — and the launch form underneath. Picking a chip changes the form in place. A launchpad can be selected only where SER has it set up; otherwise its chip is dimmed and marked as not live, the page says why, and there is nothing to fill in.
SER’s 90/10 creator-fee model is the same on both, and so is the way you launch: you fund a one-time launch address. What differs is what you pay with, where you send it from, how the split is enforced and how sers are paid:
On Solana (pump.fun)
SOL- You pay in SOL. Amounts on the form and the status page are in SOL.
- You send from any Solana wallet — Phantom, Solflare or Backpack, for example — or an exchange withdrawal. You never connect it to SER.
- The split is set through pump.fun’s own fee sharing in the launch transaction — to SER’s reward and buyback addresses — then locked. There is no SER contract on Solana.
- Rewards are in the coin’s pair token — SOL by default. Rewards are allocated to sers who saved a Solana address, but payouts are not live yet: an allocation is not a payment.
On Robinhood Chain (pons)
ETH- You pay in ETH. Amounts on the form and the status page are in ETH.
- You send from an EVM wallet on Robinhood Chain, or an exchange withdrawal that supports the chain. You never connect it to SER.
- The split is enforced by the token’s SER fee router, a contract that receives the token’s creator fees.
- Rewards are in ETH (delivered as WETH) and any other asset the router receives. Sers claim them onchain with a Merkle proof.
- A one-time address launches itNothing for a wallet to sign
- No sign-up, no accountOnly sers sign up
- 90/10 shown firstYou confirm it before launching
How it works, with a SOL and an ETH example
No wallet connection required. Your coin is launched by a one-time address SER generates, so there is nothing for a wallet to connect to or sign. No sign-up and no account either. Launchers don’t sign up. Only sers sign up.
Describe your coin, choose how often its reward pool is allocated, and send the quoted amount to a one-time launch address — from any wallet or exchange withdrawal that supports the chain. That address launches the coin, and the status page shows each step. This is how every coin is launched through SER, on both launchpads.
Every launch uses SER’s creator-fee routing: 90% to the sers’ reward pool, 10% to SER for $SER buyback & burn. The routing is shown before you launch, and you confirm “I understand that this launch uses SER’s 90/10 creator-fee model.” How the 90/10 model works.
On Solana (pump.fun)
SOLSend the quoted amount of SOL, on Solana, to the launch address shown on the status page.
Worked example
You add an initial buy of 0.5 SOL. The quote is that 0.5 SOL, plus the account rent and network fees SER reads from Solana at that moment, plus a small safety reserve. You send exactly the quoted total; what isn’t used comes back to your refund wallet in SOL.
On Robinhood Chain (pons)
ETHSend the quoted amount of ETH, on Robinhood Chain, to the launch address shown on the status page.
Worked example
You add an initial buy of 0.05 ETH. The quote is that 0.05 ETH, plus the pons launch fee read onchain at that moment, plus estimated gas and a small safety reserve. You send exactly the quoted total; what isn’t used comes back to your refund wallet in ETH.
- You choose, onceName, ticker, image, links, cadence
- Comes back to youUnused SOL or ETH, and initial-buy coins
- Goes to the sersThe coin’s creator fees and its rewards
The full list, and who holds what onchain
The coin’s creator fees fund the sers’ reward pool: SER pays the sers who post about the coin.
- What you choose, once. The coin’s name, ticker, image and links, how often its reward pool is allocated, the pair on pump.fun and the optional creator fee. These are launch settings. You can’t change them after the launch is created — not with your manage link, and not anywhere else.
- What comes back to you. Unused SOL or ETH goes to your refund wallet. If you add an initial buy, the coins it buys are delivered there too. They are coins you paid for, like any other buyer’s. Owning them is not control of the coin.
- What you don’t get. No admin rights over the coin, no share of its creator fees, no way to claim or redirect them, and no rewards for launching. Rewards go to the sers who post about the coin.
On Solana (pump.fun)
SOL- The one-time address creates the coin. In the same transaction, pump.fun’s fee sharing for the coin is set to two addresses — SER’s reward wallet for sers and SER’s buyback treasury — and the right to change it is given up.
- No address of yours is the coin’s creator or one of its fee recipients.
On Robinhood Chain (pons)
ETH- The one-time address sends the pons launch, then hands the token’s creator fees to the token’s SER fee router, a contract that only splits what it receives.
- No address of yours is the token’s deployer or its creator-fee recipient.
- No exception: creator fees never go to the launcher. If SER’s creator-fee policy changes before the launch is sent, nothing is launched and your deposit is refundable. Once the token exists, its creator fees go to its SER fee router.

SER rewards
Pick the cadence for the coin’s reward pool: every 15 or 30 minutes, or every 1, 6, 12 or 24 hours. On pump.fun, pick the pair (SOL by default). On pons you can also set an optional creator fee with a slider (default 0%). These are fixed once the launch is created. - 03
Ready to launch
Add an optional initial buy and your refund wallet — a SOL address on Solana for a pump.fun launch, an ETH address on Robinhood Chain for a pons launch — and review the exact cost breakdown. - 04
Fund the launch address
Send the quoted total, in SOL or in ETH, before the quote expires. SER waits for the deposit to be confirmed onchain before it counts it. - 05
Launch
The one-time address sends the launch, and the coin’s creator fees are routed to SER’s 90/10 split. The status page shows each step as it happens and links to the coin’s page on SER once it is live.

Who pays it, where it goes and the trade-off
Where a launchpad lets the creator set their creator fee, SER shows a fee slider when you launch. Where a launchpad has no adjustable creator fee, SER shows no control and the launch carries none of your own.
On Solana (pump.fun)
SOLOn coins paired with SOL — the default — pump.fun sets the creator fee and it can’t be adjusted, so SER shows no fee slider. The rate is pump.fun’s, it can change, and SER does not promise one.
pump.fun lets the creator choose the fee only for coins paired with certain other tokens. SER shows the slider, with pump.fun’s rules next to it, only for a pairing it offers.
Either way the fee is paid in the pair token, and all of it goes through the 90/10 split.
On Robinhood Chain (pons)
ETH- What it is. An extra trading fee on your token, set by you, from 0% up to the limit pons allows at that moment. The slider reads that limit from pons’ contracts on Robinhood Chain. The default is 0%.
- Who pays it. Traders. pons charges it on every buy and every sell, on top of pons’ base trading fee.
- It is permanent. pons fixes the fee in your token at launch. It can’t be changed afterwards — not by you and not by SER.
- Where it goes. All of it goes to your token’s SER fee router, which splits it like the rest of your creator fees: 90% to the sers’ reward pool, 10% to SER buyback & burn.
The trade-off. A higher fee makes your token more expensive to trade, which can mean less trading. Where there is a slider, it shows the total a trader pays per buy or sell before you confirm.
SER checks the fee against the launchpad’s live limit when you create the launch and again right before launching. If the limit has dropped below the fee you chose, SER stops instead of launching at a different fee, and you can request a refund.

The quote is the exact total to send. The status page shows each part of it, in the chain’s own unit.
On Solana (pump.fun)
SOL- Account rent and network fees, read from Solana when the quote is made.
- Your optional initial buy, in SOL. An initial buy is offered on the SOL pair only: the launch address is funded with SOL and SER doesn’t swap for you.
- A small safety reserve for fee movement, returned if unused.
On Robinhood Chain (pons)
ETH- The pons launch fee, read onchain when the quote is made.
- Estimated gas for the launch and the fee-router registration.
- Your optional initial buy, in ETH.
- A small safety reserve for gas movement, returned if unused.
- Quotes expire (30 minutes by default). The status page shows a countdown.
- Funds that arrive after the quote expires never launch automatically. Refresh the quote to launch, or request a refund.
- If the launchpad’s own cost rises above the quote before launch — for example pons raises its launch fee — SER stops instead of launching, and you can refresh or refund.
SER temporarily operates the launch signer
The one-time launch address is a key SER creates for your launch and nothing else. While your SOL or ETH sits there, SER operates the key on your behalf: it pays the launch costs, sends the launch, routes the coin’s creator fees, and returns what’s left.
- One key, one launchCreated for your launch and nothing else
- Key kept out of the appNever in SER’s database or your browser
- Unused funds returnTo your refund wallet
Where the key lives and what the address can send
- The key is created and held in a key-custody service (on test networks, an encrypted key store). It is never stored in SER’s database and never appears in the app, logs, API responses or your browser.
- One deposit can’t launch twice, and the address never sends anything but the transactions listed below.
On Solana (pump.fun)
SOL- It sends the pump.fun launch. That one transaction creates the coin, sets pump.fun’s fee sharing to the 90/10 split and gives up the right to change it.
- Unused SOL — the safety reserve and leftover fees — goes back to your refund wallet. Without one, request it with your manage link.
- Initial-buy coins are delivered to your refund wallet, which is required when you add an initial buy and must be a Solana wallet address.
On Robinhood Chain (pons)
ETH- It sends the pons launch, the hand-off of your token’s creator fees to its SER fee router, and the fee-router registration.
- Unused ETH — the safety reserve and leftover gas — goes back to your refund wallet. Without one, request it with your manage link.
- It holds your token’s creator-fee role only for the seconds between the launch and the hand-off (pons derives the token’s address from the fee recipient, so a launch can’t name its own router). pons credits creator fees when it sweeps them, so the fees from the first trades reach the SER fee router too.
- Initial-buy tokens are delivered to your refund wallet, which is required when you add an initial buy.
Until your launch completes you are trusting SER to operate that address as described. Send only the quoted amount, and set a refund wallet so that whatever isn’t used has somewhere to go.

Don’t use an exchange deposit address
A refund is a plain transfer with no memo, tag or deposit reference, so an exchange may not credit it — and an exchange address may not support Robinhood Chain at all. Use a wallet you control.
What it receives and which address to give
The refund wallet is the one address you give SER. Unused funds and any refund go there, and so do the coins from an initial buy — which is why it is required when you add an initial buy. Those coins are yours because you paid for them; they give you no control of the coin. Without an initial buy the refund wallet is optional but recommended; you can add or change it later with your manage link. You type or paste the address — it is never connected to SER.
On Solana (pump.fun)
SOL- A SOL address: your own Solana wallet address, as shown in Phantom, Solflare, Backpack or any other Solana wallet.
- It must be a wallet. A token account or a program address is refused, because nobody holds a key for it.
On Robinhood Chain (pons)
ETH- An ETH address on Robinhood Chain: your own wallet address, starting with 0x.
- SER checks the address’s checksum when it has one, so a mistyped character is caught. The zero address is refused.
Refunds and expiry
- Failed launch: you see the reason and the balance, and can request a refund. Retry is offered only when no launch transaction was sent; SER never re-signs a launch that reached the chain.
- Expired quote: refresh the quote to launch (SER reads the launch costs again and keeps the same launch address), or request a refund.
- A refund sends the launch address balance, minus the network fee for the refund itself, to your refund wallet — in SOL to a Solana wallet for a pump.fun launch, in ETH to an EVM wallet for a pons launch.
- The refund wallet can be set or changed only with your manage link.
Your manage link
When you create a launch, SER shows a manage link once. It is the only way to set the refund wallet, retry, refresh the quote or request a refund. SER stores only a fingerprint of it and cannot recover it — save it before you leave the page. The key sits after the # sign of the link, so it never lands in server logs or referrer headers.
That is all the manage link does. It can’t change the coin, its reward settings or its fee split, and it can’t claim creator fees or rewards. It is not an account, and it is not a sign-up.

- SER is sending the launch: on Solana the pump.fun transaction that also locks the fee split; on Robinhood Chain the pons launch, then the fee-router hand-off and registration.
- Live
- The coin exists and its creator fees are routed through the 90/10 split. The status page links to the coin’s page on SER.
- Failed
- The launch didn’t complete. The reason is shown; retry or request a refund.
- Expired
- The quote lapsed. Refresh it or request a refund.
- Refund available
- Your balance can be returned. Request the refund with your manage link.
- Refund pending / Refunded
- Your SOL or ETH is on its way back, or has been returned.
Only sers sign up
Launching needs no sign-up, no account and no wallet connection. Launchers don’t sign up. Only sers sign up. Signing in is a separate thing, for sers who want to link their socials, earn and receive rewards: on the Become a ser page, with a social account (X, Farcaster or Telegram), Google or email, then they save the address their rewards go to. No wallet connection required there either. SER never asks for a seed phrase or private key. SER rewards.
pump.fun on Solana: what you rely on
- How the split works. There is no SER contract on Solana. The launch transaction sets pump.fun’s own fee sharing for your coin — 90% to the reward wallet for sers, 10% to SER’s buyback treasury — and gives up the right to change it in the same step, so the launch address can’t alter it afterwards.
- SER checks before it says “routed”. After the launch confirms, SER reads the coin’s fee-sharing config back from Solana. Only when it is exactly that split, and locked, does the page say the fees are routed. If it is not, the page says so and the coin’s rewards stay paused.
- Coin details. pump.fun writes the name and ticker onchain. The description, image and links are served by SER at the metadata address the coin points to, and can’t be edited after the launch is created.
- Payout wallet. Sers are paid, not the launcher. To be allocated rewards from pump.fun launches, a ser signs in with a Solana wallet — it is then their payout wallet — or links one on their dashboard. Either way the wallet is proven by signing a message with it — free, with no transaction.
What you are relying on with pump.fun
pump.fun’s admin can reassign a coin’s creator or reset its fee split without notice. Neither you nor SER can prevent that. SER watches for it, shows it on the coin’s page and pauses the coin’s rewards if it happens.
Creator fee rates are set by pump.fun and can change. The split applies only to the creator fee, never to pump.fun’s own fee.
Rewards on Solana are allocated to sers who saved a Solana address, but payouts are not live yet. The buyback from SER’s share is not live on Solana yet.
SER is an independent application and is not affiliated with pump.fun.
pons on Robinhood Chain: what you rely on
- Where the launch goes. The launch transaction goes to the pons factory. pons creates the fixed-supply token and its pool; SER does not deploy a token factory of its own and does not change how pons handles liquidity, fees or graduation.
- SER checks before it sends. pons has more than one contract generation and can open or close launches. SER re-checks launch eligibility and the launch fee onchain immediately before a launch is sent rather than assuming them.
- The split is a contract. The token’s SER fee router copies the 90/10 policy when it is created and keeps it for life. It is the token’s creator-fee recipient; you are not.
What you are relying on with pons
For pons v2 tokens, the pons owner can override a token’s creator-fee recipient after a 3-day timelock. Neither you nor SER can prevent that. SER shows a notice on the token page while an override is pending.
pons sets its own launch fee and base trading fee and can change them. The split applies only to the creator-side fees pons pays out.
SER is an independent application and is not affiliated with pons.
