Overview
Triplets launches one memecoin on three chains at the same time: Robinhood Chain via PONS, Solana via pump.fun and BNB Chain via Flap. The three tokens share a name, a ticker, a picture and an opening price. After launch a bot funded by trading fees keeps the three market caps within 5% of each other.
A launch is community funded. The creator sets a goal in dollars, backers send ETH, SOL or BNB to plain addresses, and the coin is created the moment the goal is reached. Backers are inside the very first buy on every chain, so nobody can get in before them.
Robinhood ChainPONS. The reference chain. Funding, credits and refunds settle here.
Solanapump.fun. Create and first buy in one transaction.
BNB ChainFlap. Same coin, same opening price, fresh launch wallet.Launching a coin
- Connect a wallet on Robinhood Chain.Creating costs only gas.
- Name, ticker, picture.Up to 32 characters, up to 10 characters, under 4 MB. The picture is pinned to IPFS and used on all three chains.
- Goal and window.A goal from $2,500 and a window between 1 hour and 7 days. Presets from $2,500 to $25,000 show the opening market cap they give.
- Share the three addresses.The coin's page shows progress, backers and pending transfers in real time.
Backing a coin
There is no app to install and nothing to sign. Send ETH, SOL or BNB from your own wallet to the address shown for that chain. The minimum is about $3.
- Transfers on Solana and BNB Chain are bridged to Robinhood Chain and credited to you there. Each step and its transaction hash is on the coin's page.
- Anything above what is left of the goal is refunded to the sender automatically.
- Once the goal is hit, new transfers are rejected. On Solana they are returned.
- Your coins arrive on the chain you paid from, in the launch transaction itself.
Where the money goes
When the goal is reached, the raise is split in a fixed way.
The launch
- Goal reachedFunding closes. New transfers are rejected or returned.
- Fresh walletsOne launch wallet per chain and one bot wallet per chain, all derived for this launch and never used before. Nobody can watch a deployer address and front-run it, and nothing links one launch to the next.
- Create and first buy, atomicallyOn every chain the coin is created and the first buy is made in one transaction. On Solana the transaction is compressed with an address lookup table so create and buy always fit together.
- Coins deliveredEach backer's coins land in the wallet they paid from, on the chain they paid from.
- Gas sweptLeftover gas is swept back. Every transaction is linked from the coin's page.
The price-keeping bot
The bot watches the three market caps and trades whenever they drift apart. Robinhood Chain is the reference. When a chain is cheaper than the reference the bot buys there; when it is dearer the bot sells there. Every trade, its reason and the bot's inventory per chain are shown on the coin's page.
| Target | The three market caps within 5% of each other |
|---|---|
| Above $100,000 | The band tightens further |
| Arms at | A reference market cap above $2,000, where the curves are thick enough to matter |
| Per trade | Closes half the gap, capped at $500, never below its reserve |
| Inventory | About half of each chain's holding as coins and half as cash, so it can move a price both ways |
| Wallets | Its own on every chain, for this coin only. It can only ever spend this coin's launch cash, sale proceeds and fees; no coin ever trades with another coin's money |
| Funding | Half the raise at launch, then 2% of every trade afterwards |
Refunds and misses
If the window closes before the goal is reached, every backer is refunded automatically to the wallet they paid from, on the chain they paid from. Missed coins stay visible for two days so backers can find their refund transactions.
The backers of that chain get their share back on the chain they paid from, retried until every refund is through. The coin's page shows the leg as failed. The other chains proceed.
