# Longevity (longevity.trading)

> Launch higher. Last longer. The cross-chain launchpad and OTC desk with a fairer open, holder rounds every 10 minutes and one supply on every chain.

Longevity is a cross-chain coin launchpad and OTC desk, built so that coins last longer and holding is rewarded. A coin
launches on Solana, its home chain, and can exist on the other chains below from day one with one shared supply.
The open is fairer: early bots and bundles pay a 99% fee in the first 3 slots. Every coin pays its holders SOL
as often as every 10 minutes, weighted by how long each has held. The creator's share of the trading fees builds up from the first trade and
is paid as the coin grows, or goes to the holders if the creator chooses. This file is for agents and integrators: what the product does, the numbers it runs on, where the
data is, and what not to claim. Everything below is generated from the code's own constants; nothing is typed in by hand.

## State of this deployment

- Solana: live: the engine is configured and launches are open.
- Base: not open on this deployment. The contracts and the keeper are built and tested. Describe it as live only when this line says so.
- Robinhood Chain: not open on this deployment. The contracts and the keeper are built and tested. Describe it as live only when this line says so.
- BNB Chain: not open on this deployment. The contracts and the keeper are built and tested. Describe it as live only when this line says so.
- Hyperliquid: not open on this deployment. The contracts and the keeper are built and tested. Describe it as live only when this line says so.
- The trading-fee split between the creator and the platform is announced later. Describe "the creator's share" and "the platform's share" in words; never give a percentage.

## How a launch works

1. Pay the launch fee: 0.25 SOL, to Longevity's wallet. A ticker or a name that a live coin holds is refused. Reusing the ticker of a coin that has lapsed costs 1 SOL more, returned if the new coin graduates within 48 hours. The launch fee is refunded if the coin graduates clean (no early buyer linked to the launcher).
2. The launch: you pay once and the worker creates the coin within seconds, from Longevity's deployer wallet and a secret-derived mint. While the opening fee is on (step 3), every buy in the first three slots after creation pays 99%. A bot or a bundle can still buy in those slots and pays 99% to do it; from the fourth slot everyone pays the coin's normal fee, bundles included. So bundling the open is expensive, not impossible. The mint exists nowhere before the launch transaction, so nothing can be aimed at it in advance. The one exception to the opening fee is the creator's declared first buy (devBuyLamports on the intent, up to 10 SOL), which rides inside the launch transaction as the pool's first swap at the normal fee and is printed on the coin page. With none, the worker takes that first swap with a 0.001 SOL buy of its own and sends what it bought to the incinerator, an address nobody holds the key to. If the worker cannot create the coin, the payment is refunded.
3. The curve: a Meteora bonding curve that opens at a $20K market cap and graduates at $150K into the coin's own pool. The creator picks a 1% or 3% fee. Every launch opens with a fee of 99% on the first 3 slots (about 1.2 seconds), then the coin's fee. That opening fee is a fixed rule, not an option.
4. Early buyers and the launcher: the worker reads which wallet first funded each buyer in the first slots and links wallets to the launcher that way. That decides which wallets the early-selling rule in step 5 counts, whether the coin qualifies for the Summit Bounty and whether the launch fee comes back at graduation. No verdict is published; trading terminals show bundle statistics natively.
5. Creator trading fees: every trade pays a trading fee, and a share of it is the creator's. It builds up from the first trade and is paid as the coin grows. Nothing is paid for 3 days. After that, the launcher is paid up to a share of everything that has built up: 25% once the coin has peaked at $50K, everything once it graduates, topped up at most every 6 hours. The share is forfeited, and stays forfeited, if the launcher's wallets (the launcher plus the wallets linked to it in step 4) sold more than 50% of what they bought in those 3 days. A coin that has not graduated and has not traded for 7 days is abandoned: what is still waiting is forfeited. Every forfeit funds the bounty in full. The creator's own wallet is a holder like any other: the coins it holds earn the holder rewards below on the same terms, and neither this schedule nor a forfeit changes that.
6. Graduation: the creator's half of the pool position is locked for good; the platform's half is withdrawn at graduation to a Longevity wallet, so the liquidity that stays is all locked.
7. Pairs: a coin is priced in SOL or in any coin launched on Longevity, up to two deep (the chain must end in SOL). Buying a paired coin buys its pair first, in the same transaction. Nothing else is offered as a pair.

## Where the creator's share goes

Chosen at launch (payoutDest on the intent) and fixed for the coin: the launcher's wallet when nothing is chosen; another Solana wallet; a wallet on another chain, delivered through Longevity's payout wallet in that chain's coin or USDC (only where /api/launch/solana/blind/info says anyChainPayouts); an @handle on X, TikTok, Instagram, GitHub, Twitch, where the money waits until its owner signs in and names a wallet (only on the platforms /api/launch/solana/blind/info lists in handlePlatforms, the ones whose sign-in is switched on; an empty list means no handle is accepted); or the coin's holders. The first four are paid only as the schedule in step 5 releases money, and a forfeit reaches none of them.
Holder rewards: every coin pays its holders a share of every trading fee; nothing is held or locked. The worker snapshots the holders every 10 minutes and, once the pot has reached the round's minimum, pays the share that came in, in SOL: as often as every 10 minutes. Each round's pot is split by coins held times the multiplier for how long you have held them: 1× after 10 minutes, 2× after an hour, 3× after two hours, 4× after three hours and 5× after four hours. Coins you add later start their own clock and do not change what your older coins count for. Sell, or move coins out, and every coin the wallet holds starts over at round one: it earns no share that round, and that share goes to the wallets that stayed. What it was already owed stays owed. Coins bought since the last round count for nothing in that round, and a wallet holding less than $20 of the coin earns no share that round. A round splits its pot once the pot holds 0.05 SOL, between every wallet that qualifies; a smaller pot carries over to the next round, so a quiet coin pays less often and nothing is lost. Each round sends as many as 720 payments, to the wallets owed the most. A share that is not sent, or is too small to send, stays owed to the same wallet and is paid in a later round. A wallet with no SOL in it is paid once what it is owed reaches 0.0009 SOL, the least Solana lets a wallet hold. A creator who picks { kind: "holders" } as the destination adds their own share to the same rounds; final once set, only a community takeover changes it. The other chains pay the same rounds in their native coin when they open. The one exception is Longevity's own coin, whose fees Longevity retains until it announces otherwise (its coin JSON carries mainCoin: true). Describe holder rewards as paid in SOL on every coin, by coins held and how long they have been held; never "in the paired asset" and never a basket.

## The weekly Summit Bounty

- Pool: every creator fee that is forfeited, in full.
- Tiers: Peak breaks $500K and holds at least $400K; Summit breaks $1M and holds at least $800K; both for 24 hours, with first buyers not linked to the creator. A coin wins only its highest tier in a week. A coin whose creator forfeited, or that was taken over, can still win: the creator's part then buys the coin back and burns it. A week with a winner less than 3 days old pays out once that coin's first 3 days are over.
- Each winner's share: 30% to the creator, 50% to its top 50 holders pro rata (each capped at 10% of that part; the creator's wallets are left out of this part, because the creator is paid directly), 20% buys the coin in its own pool and burns what it bought. This is the bounty's split, not the trading-fee split.

## Staking

Staking (the stake_vault program, one vault per coin, open from launch): staked coins count as held in the holder rounds and count for more: × 1 with no lock, × 1.5 for a 7-day lock, × 2 for 30 days, on top of the multiplier for how long they have been held. On Solana a stake is counted against the coins the wallet has held longest. No SOL goes into a vault; the rounds pay the wallet. Unstaking before the lock ends is allowed and costs a tenth of what leaves, kept by the program for Longevity's treasury (EARLY_UNSTAKE_PENALTY_BPS 1000); nothing is charged after the lock. Adding to a locked stake keeps at least its lock. Staking is not a sell: staked coins keep the time they have been held. Community takeover: Longevity may name the wallet an abandoned coin's creator fees go to from then on (lib/cto.mjs); the coin's JSON carries a takeover field. The holders' pot, the creator's share and Longevity's come out of the same trading fee; none is printed as a percentage. Data: https://longevity.trading/api/engine/stakes?wallet= (a wallet's positions); the vault and position accounts are readable on chain (engine/src/stake-vault.mjs).

## The OTC desk

Private deals: a maker names the counterparty and the amount, prices the deal and signs once; nothing leaves either wallet until the taker signs. One transaction moves the coins and the SOL (or an accepted quote token) together; a durable nonce keeps the maker's signature alive and the deal_guard program enforces the deadline; the pool never sees the trade. Two ways to price: a fixed total, for any Solana coin; or at market, for a coin launched here and paired with SOL: the deal settles at the coin's pool price when it lands, plus or minus the maker's offset, inside a floor (seller) or ceiling (buyer) the maker signed. A market fill is refused unless the pool sits within 3% of a reference price Longevity posted on chain in the last 45 seconds, and refused if any pool trade rides in the same transaction. A flat 0.3% fee on the price, taken from the seller's proceeds. Cancel by advancing the nonce. On the EVM chains the desk is one contract per chain (OtcDesk: an EIP-712 order the maker signs, filled by the taker in one transaction, fixed or market priced against the coin's own pool). It runs on a chain that reads live under "State of this deployment".
Data: https://longevity.trading/api/otc/feed (filled deals), https://longevity.trading/api/otc/deals?wallet= (a wallet's deals), https://longevity.trading/api/otc/quote (the pool's quote for the same size, for comparison), https://longevity.trading/api/otc/pool?mint= (the pool a market deal prices against, its price now and the posted reference).

## One supply, every chain

A coin can be picked for Base, Robinhood Chain, BNB Chain, Hyperliquid at launch. One shared supply: when the coin graduates, 5% of the supply opens each chosen chain's pool at the Solana price, and vaults on each chain trade in the open to keep the prices in line. Per-chain pool fees are charged at launch; the twin wiring fee is 0.25 SOL. Describe it as open on a chain only when that chain reads live under "State of this deployment".

## Built, switching on when deployed

- Fee routes for the creator's share (the launch_vault program, not deployed): posters, a split of up to four wallets, a handle vault for an account on X, TikTok, Instagram, GitHub, Twitch (fees wait until the account signs in and claims), a buyback of the coin, games (jackpot, last buyer wins, biggest buy of the day, buy streaks, referral cut, best callers), an agent-traded pot, delivery on another chain.
- Hooks (the rule_hook program, not deployed): wallet caps, trading hours, sell cooldowns, presets and hooks in plain words.
- uPEG (not deployed): every whole unit a numbered NFT.
Describe these as built and switching on, never as live.

## Indexing for trading terminals and screeners (https://longevity.trading/integrate/indexing; JSON: "indexing" in https://longevity.trading/api/integrate/kit.json)

Solana (where every coin is launched): a coin is a Meteora DBC pool (dbcij3LWUppWqq96dh6gJWwBifmcGfLSB5D4DuSMaqN) whose config's feeClaimer is 5sT9hg8BarehzhJo813wDJ2dAf84ycEcfgiQG2UAwfta; it graduates into DAMM v2 (cpamdpZCGKUy5JxQXB4dcpGPiikHawvSWAd6mEn1sGG). The pool's creator field is Longevity's deployer wallet, and so is the fee payer of the launch transaction: the engine launches every coin, so neither names the launcher. The launcher's wallet is coin.launcher in GET /api/engine/coin/<mint> on this site. Standard configs: 2u8jc9PEY91MzyF5py1YaAypKzwqYPmNRcsBygYz9Tf7 (1%), N88JJBVL7iYRqQDFmy1nt7Jb2BLRyncVeLshPxEbXkv (3%), BSfxrCqGQQY4M9ZoXhA3cHKw5Rj44nwrjehpSWBLk7zn (1%), C5shbPrZt5T4vC6PwFSAJPJg3ZqUtJHN3sSzkQG3gPNe (3%). The site reads at finalized. A coin is New until progress = quoteReserve / migrationQuoteThreshold reaches 0.8 (a suggestion), Almost bonded after, Completed at graduation. The engine's own view of a coin (job, bundle check, the creator's trading fees, bounty check): https://longevity.trading/api/engine/coin/{mint}.

EVM: no coin is launched there. A coin that picked a chain gets a token and, at graduation, one pool:
TwinOFTFactory: TwinDeployed 0x526acdb32d2df5740fc359641571a78159b8dd41ef31c57010c63e9043a6e5ed. Creates the token of a coin that picked this chain. The address is the same on every chain. No pool exists yet at this point.
AlignedListingFactory: Listed 0xad5a4aaa469875ff13658232c22a8ba97398205fa40bdf452cdbd83b1ee2d117. Opens the coin's Uniswap v4 pool on this chain when the coin graduates on Solana. The AlignedPoolSeeder calls it with the coin's slice and the Solana price. One pool per coin per chain. PoolKey: currency0 = quote, currency1 = token, fee = 0x800000 (the v4 dynamic-fee flag), tickSpacing = 200, hooks = the chain's FeeStyleHook. The quote is the chain's native coin (the zero address) or, for a paired coin, its parent coin's token on this chain. Read the key with alignedFactory.poolKeyOf(token); the fee a swap pays now is feeStyleHook.quoteFee(key, params).
No Longevity contract address is published: no EVM chain reads live.
Trades: PoolManager (Uniswap v4).Swap 0x40e9cecb9f5f1f1c5b9c97dec2917b7ee92e57ba5563708daca94dd84ad7112f, topic1 = poolId. The site's indexer stays 10 blocks behind the head and drops rows whose block hash changed.

## Words

Call a chain live only when "State of this deployment" says it is. Never say a launch cannot be bundled: a bot or a bundle can still buy in the first three slots and pays the opening fee to do it. Say "creator trading fees, paid as the coin grows", not "fees held"; "held" is only the coin page's label for an amount waiting to be paid. Never "audited", "guaranteed", "risk-free" or a price target. Never a trading-fee split percentage. Never a pair other than SOL or a Longevity coin. The trading fee is 1% or 3%, never a third choice. Holder rewards are paid in SOL, by coins held and how long they have been held, never in a paired asset. The product is Longevity; it has no other name.
