symbientDocs/How it works
A coin, a curve, and one film that trading pays for.
symbient is a launchpad on Robinhood Chain. Every coin opens on its own curve, against ETH or a stock token you choose, and ships one film. The model writes the song and the picture. Trading pays for it.
Launch
Launch on the Symbient curve with a name, a mark, and a short description. Trading fills the coin's purse, and the purse pays for one film. Launching does not render it and does not mint a key.
Watch the film
The stage plays that one cut. While it is being made, it shows the shoot. Watching spends nothing and does not mint a key.

01
Two doors
There are two ways a coin gets onto the stage.
Door one
$SYMBI
Created on Mosh. The Swarm is its creator. Of the fees that clear Pons, funders receive 60, the team 20, and Mosh 20. The team share, 25% of the bundle's 80%, pays for its film. Funders claim their own. Its trades do not enter the fee split below.
Door two
Every other coin
Opens on the Symbient curve. You sign from your wallet. The curve holds the market. Buys and sells hit that contract, and the fee stays there. The factory is ours, so the 1% a PONS launch gives away stays here.
02
Launch a coin
A launch is one transaction from your wallet. You choose six things, and every one is written into the coin.
- Name and symbol
- Names and symbols are not unique. The token address is the identifier.
- Mark
- The logo. It is written into the token and frozen.
- Pairs
- One to 5. ETH, or Robinhood stock tokens such as NVDA, AMC, or TSLA.
- About
- What the coin is. It is kept with the coin. The model writes the lines, the tempo, and the picture. There is no lyric box.
- Film model
- Claude Opus 5.5 or GPT-6.1 Sol. The model writes the program that paints the film. You do not direct each scene.
- Opening buy
- Optional. It happens in the same transaction and is exempt from the snipe fee.
03
Several pairs
A coin is not tied to one pair. The creator picks from one to 5: ETH, Robinhood stock tokens such as NVDA, AMC, or TSLA, or a mix. ETH is a choice, not a requirement.
- One curve per pair
- Supply is split equally across the pairs. Each pair gets its own curve with its slice of the opening reserve, its own price, and its own graduation. A buy on the NVDA curve is paid in NVDA.
- Same opening value
- The pricer sets each curve's starting reserve so every pair opens at the same dollar market cap.
- Prices stay together
- It is one token on every book. A buy that lifts one curve is met by sellers on the others, so a trade lands on the depth of all of them.
- One price on the page
- One price, one market cap, one volume. The price is each curve's last price weighted by the supply it still holds. The trade panel can buy and sell across every pair at once.
- Which pairs qualify
- The pricer must be able to value the pair in ETH through Uniswap pools, each holding a minimum depth, on a 30-minute average price. The house token is never a pair. Fee-on-transfer tokens cannot be a pair. Whether USDG is offered is still to decide.
- Fees swept to ETH
- Each curve takes the fee in its own pair. A sweep sells it to ETH along the route that priced the pair. A fee that cannot be sold yet is held and retried. Anyone can run a sweep, and it carries a minimum out.
- The risk is the pair's
- A coin quoted in an asset is worth nothing if that asset goes to zero. A pair we do not curate is labelled wild.
04
Trade
Buys and sells go to that coin's curve. The price rises as people buy and falls as they sell. Fees come off the pair you trade in. The trade panel shows the rate the coin is on, the round trip, and the snipe fee before you sign.
At 5.00% a buy and a sell cost about 10%. At 3.00% they cost about 6%. That is before price impact and the snipe fee, and the first buyers pay the higher one.
A buy larger than what is left on a curve fills what remains, charges only for that, and returns the rest in the same transaction.
05
Snipe protection
Every coin launches with an anti-snipe fee. It is not optional. A creator cannot turn it off or shorten it. A bot that buys the opening of a curve before anyone else has seen it pays for being first.
- Buys only
- Selling is never charged it.
- Taken first
- The fee comes off the amount in before the curve prices the trade. It is capped so the buyer nets at least 1% of the spend.
- Not burned
- What is collected joins that trade's fee and is split the same way. The value a sniper gives up flows back to the coin.
- The creator is exempt
- The launching address, the creator fee recipient, and the opening buy are exempt. Up to 32 more addresses can be named at launch. The list is fixed.
- Keyed to the recipient
- The fee follows the wallet receiving the tokens, not the sender.
- Terms fixed at launch
- A coin keeps the window it launched under. Nobody can change it.
- Several pairs
- Every curve opens in the same launch transaction, so every window starts at the same moment. A sniper cannot skip the fee by using the pair nobody is watching.
06
Graduation
A coin trades on its curve until the curve sells out. Then it becomes a Uniswap v4 pool whose liquidity is locked for good. It works the way it does on PONS.
- 1Sells outThe last buy closes the curve.
- 2SweptWhat it collected moves to the seed.
- 3Pool createdA v4 pool with the Symbient hook.
- 4LockedThe position can never be taken out.
- A fixed share is held back
- Part of the supply is reserved to seed the pool: supply × phantom reserve ÷ (phantom reserve + threshold). Every coin on the same settings graduates into a pool of the same size at the same price.
- Inside the last buy
- The buy that sells out the curve graduates it. A buy larger than what is left fills the rest and refunds the remainder, so nobody can block a graduation by slipping in a small buy.
- Sells close early
- From the moment the curve is ready to graduate it holds the pool's reserves, so sells wait for the pool. That is normally the same transaction.
- Anyone can finish it
- If the automatic step fails, anyone can run the create-pool call. It needs neither the creator nor Symbient. Stuck for seven days, the collected funds can be returned and the coin is marked.
- The pool is locked
- A full-range position in a locker with no way out. Leftover supply is locked there too.
- With several pairs
- Each curve graduates on its own into its own pool, TOKEN/NVDA or TOKEN/AMC. Thresholds are counted in the pair and fixed at launch. The others keep trading.
The Symbient hook
Traders pay the same rate on the pool as on the curve of that coin. The pool charges no fee of its own. A Uniswap v4 hook takes the fee on every swap and holds it until the sweep. It stores no percentage. On each swap it asks that coin's curve whether the fee has dropped.
One hook, every pool
One hook serves every graduated pool of every coin, and every pair of a multi-pair coin.
Set at creation
The hook is part of the pool key, so graduation creates each pool with it attached.
Mined address
Its permissions are encoded in its address, found by mining a CREATE2 salt.
Fee in the pair
Taken on the input or the output side so it is always in the pair, never in the coin's own token.
The cost is routing. A hooked pool is not a plain v4 pool, and some aggregators may not route to it. The Symbient site routes to it either way.
07
Fees
Traders pay 5.00% until the coin's purse is worth its film cap, or 7 days after launch, whichever comes first. Then they pay 3.00%. The curve reads its own purse and the clock. It does not wait for the film, and nobody attests the timing. Whichever pairs a coin trades on, the fee is swept to ETH and split there.

A trade of 100 leaves a fee of 5 at first: Symbient 1, purse 2.20, holders 0.60, the buy 0.60, the discount pot 0.40, creator 0.20. After the drop it leaves 3: Symbient 1, holders 0.60, the buy 0.60, the discount pot 0.60, creator 0.20. In the first seconds a buy also pays the anti-snipe fee, which joins that trade's fee and is split the same way. $SYMBI's own trades pay Mosh and stay out of this split.
The drop is a flag the curve writes once and never clears. Paying the purse out does not bring 5% back. The hook and every curve of the coin read the same flag.

Who earns the credit
The 0.60 is call credit for $SYMBI wallets that qualify. The official buy is the Mosh pool, and after graduation the pool that market becomes. The same gates Parabolarc uses for a rebate apply.
An epoch pays (your eligible tokens ÷ all eligible tokens) × the holder pot collected that epoch. A wallet with 1,000,000 eligible tokens receives twenty times a wallet with 50,000.

The purse
Each coin has one purse and one film. Trading fills the purse, and the purse pays for the film. It does not fund a second one.
- $20
- Opus 5.5 cap
- $20
- GPT-6.1 Sol cap
- 2.20%
- Of each trade fills it
- 7 days
- Then the fee drops anyway
- What fills it
- The extra 2% plus the standing 0.20%. At 2.20% of volume the $20 cap is about $910 traded on the coin.
- The drop
- The fee falls to 3% when the purse is worth the cap, or seven days after launch. The standing 0.20% then joins the discount pot, so cheaper calls receive 0.60.
- Held fees count
- Fees not yet swept count toward the cap on a curated pair, at the lower of a 30-minute average price and what a sweep could sell for now. On a pair we do not curate, only swept ETH counts.
- Symbient fronts the run
- Symbient pays for the model and the worker, at most 3 runs, and each start is recorded on the coin. A run that fails spends Symbient's money. The purse stays put.
- One hash settles it
- Symbient commits the hash of the finished MP4. Once it is on the coin, anyone can release the purse to Symbient, up to the amount fixed when the fee dropped. ETH above that joins the discount pot.
- No film
- After 3 starts with no hash, or seven days after the fee dropped, anyone can settle the purse to the discount pot. Symbient is not repaid. A coin that never reaches the cap in seven days drops to 3% with no film, and what it collected cheapens calls.
- The house subsidy
- On the roughly $910 that fills a purse, Symbient's 1% is about $9. Failed runs are not repaid. That is a house cost.
Price manipulation cannot trip the drop with a spot price, because every price here is a 30-minute average. A pool a creator controls cannot fill the purse, because its held fees do not count. What remains: a thin ETH price route can be pushed up for 30 minutes, which makes the cap fewer wei and pays Symbient less, and a sweep can lose up to its slippage limit. The curve and pricer are not written or audited yet.

A key
A key is a call with a name on it. It is what a card or a $SYMBI wallet spends. The discount pot pays the gap between what a buyer pays and what OpenRouter charges. The film is a separate spend, paid by the coin's purse.

The film
The film is made by the model the creator picked. Gemini draws the mascot, Gemini 3.8 Flash writes the lines and the arrangement, ElevenLabs sings them, and the film model paints the chapter. There is no video model in the loop.
The song
Written for this coin from its mark and its description, then saved. A retry uses those lines.
One cut
The stage plays that cut. Replaying it spends nothing. While it is made, the stage shows the shoot.
Dark until paid
A coin that has not filled its purse shows its description and the purse filling. A coin that never trades stays dark.

Contracts
Symbient runs on Robinhood Chain. Each launch gets its own curve and token, created by the factory, so look them up from the factory rather than hardcoding them.

Symbient contracts
The testnet splitter, burner, and launcher are deployed. The film factory is written and not deployed, so this table has no address for it. Uniswap v4 is on testnet. The stock tokens are not, so they are not in the first generation. An empty address stays empty. Sample addresses are not shown.
Symbient's own contracts are replaced as a whole set, not upgraded in place, because a hook binds to one factory for good. A token made on an earlier set keeps trading through the hook and escrow it launched against. Look up which set a token belongs to, and do not assume it.

Where it stands
The site runs on testnet with a burner wallet. The film factory is written and not deployed. The spike has not run, and stock pairs are not in this generation.

Before you trade
Coins on a curve can go to zero. A pair is an asset too, and a coin quoted in it is only worth what that asset is worth. A film is written by the models from the mark and the description. Nobody checks it, and it is not advice. The fee is 5% at first and the first buyers pay it. A purse that does not fill in seven days means no film. This is testnet and nothing here is final.
