How Echobase works
Bonding curve first, a permanently locked Uniswap v4 pool after, on the pons v2 launch protocol that also powers llmtokens.fun. A fixed 2% creator tax on every trade, donated in full to WWF.
The cause
What happens to the fee, and why there is nothing in it for the creator or for us.
Every trade funds WWF. All of it.
Echobase is a meme coin launchpad built around one rule: the fixed 2% fee on every buy and sell of every coin is donated, in full, to World Wide Fund for Nature. Not a share of it, not "profits": the whole fee, on every trade, for as long as the coin exists. The creator keeps nothing and neither do we. It is enforced by the contracts, and the wallet that collects it is public so anyone can audit it.
Launching a coin
Create in seconds
Connect MetaMask, Rabby or any EVM wallet on Robinhood Chain. Pick a name, ticker, image, description and links, and make your first buy (from 0.0001 ETH) in the same transaction. The coin is deployed on the pons v2 launch protocol with its 2% donation tax locked in.
Trade from the first block
The whole supply starts on a bonding curve at about 1.68 ETH of market cap. Anyone can buy and sell against it right away, with a decaying anti-snipe tax protecting the first seconds and your own opening buy exempt from it.
Graduate, and keep giving
When the curve raises 4.2 ETH it sells out and graduates: everything it collected plus the reserved supply opens a Uniswap v4 pool whose liquidity is locked forever. On the curve and in the pool, every trade pays 2% to the WWF donation wallet.
How a launch works
Same mechanics as llmtokens.fun, because it is the same protocol underneath. The difference is where the creator tax goes.
Bonding curve 1.68 ETH to start
The entire 1,000,000,000 supply is minted to a bonding curve with a 1.68 ETH virtual reserve, so the coin opens at about 1.68 ETH of market cap and there is always a price to buy and sell at. About 714M tokens are for sale on the curve; the other 286M are held back to seed the pool, so the curve holds exactly 4.2 ETH when it sells out.
Graduation 4.2 ETH
When the curve has raised 4.2 ETH it sells out and graduates automatically: the ETH it collected and the reserved supply open a Uniswap v4 pool at the curve's final price, and the position is locked in the pons launch locker for good.
The engine pons v2
Echobase does not run its own curve. It launches through pons v2, the open launch protocol on Robinhood Chain that llmtokens.fun uses, via a small contract of its own that locks every launch's creator tax to the WWF donation wallet and keeps the registry of coins you see here.
Fees
Fixed by the contracts. There is no fee slider and no way to change it later.
What happens on-chain
- Create. Echobase's launch contract calls the pons v2 launch-and-buy router. pons deploys a new ERC-20 with 1,000,000,000 tokens and its own bonding-curve contract, mints the whole supply to the curve, and records the creator tax (2%) and its recipient (the WWF donation wallet) for that launch. Your opening buy (at least 0.0001 ETH) is filled in the same transaction, exempt from the anti-snipe tax; pons fills the first buy inside the launch, so a launch without one is rejected.
- Bonding curve. Buys and sells go against a constant-product curve with a 1.68 ETH virtual reserve, so the coin starts at about 1.68 ETH of market cap. Fees come off the ETH leg of every trade: 2% creator tax for the donation wallet and 1% protocol fee for pons. The rest of the ETH stays in the curve.
- Anti-snipe. For the first five seconds after launch, buys pay an extra tax that starts near 99% and decays to zero. Sells are never taxed by it, and what it collects joins the launch's fee stream.
- Graduation. When the curve has raised 4.2 ETH it sells out and graduates: pons sweeps the fees, opens a Uniswap v4 pool with the collected ETH and the reserved supply at the curve's final price, and locks the position in its launch locker, which has no withdrawal path.
- After graduation. The coin trades in its Uniswap v4 pool like any other. The pons hook on that pool keeps charging the 2% creator tax on every swap, converts it to ETH against the pool itself, and credits it to the same donation wallet.
Donations
The donation wallet is a single address stored in Echobase's launch contract and stamped into every launch it makes on pons as the creator fee recipient. The 2% creator tax from curve trades and from pool swaps accrues to it, and pons' keeper sweeps it into the pons fee escrow, from which only that wallet can claim. WWF does not accept crypto directly and does not hold a wallet on Robinhood Chain, so the fees accumulate in that wallet and are converted and donated to World Wide Fund for Nature through its official donation channels. Receipts for each donation are published and linked from this site, so the wallet's outflows can be matched against them. If the wallet ever has to be rotated (for example to a new custody setup) the change is made by the contract owner and emitted on-chain as a CharityChanged event, visible to everyone.
Echobase is an independent project. It is not affiliated with, endorsed by or operated by WWF; it donates to WWF. The WWF name is a trademark of its owner.
Trading
Coins trade in a standard Uniswap V2 style pool. Use the Buy / Sell widget on each coin page or any DEX interface that supports fee-on-transfer tokens (swaps must use the "supporting fee on transfer tokens" functions). Prices, market cap and liquidity shown on this site are computed from the pool reserves in real time.
Wallets & network
Echobase works with MetaMask, Rabby, Coinbase Wallet and any wallet that injects an EVM provider. When you connect, the site offers to add Robinhood Chain (chain ID 4663, RPC rpc.mainnet.chain.robinhood.com, explorer robinscan.io) to your wallet automatically.
FAQ
Can the creator dump on buyers?
No. The creator receives zero tokens at launch and zero fees. Every token is on the curve or in the pool, so the creator has to buy at market like everyone else.
What does the creator get, then?
A coin that trades for a cause. Every buy and sell of it sends 2% to WWF, and that is the point of launching here. If you want to earn from your own coin's trading, this is the wrong launchpad.
Does WWF receive the fees directly on-chain?
No. WWF does not accept cryptocurrency directly and has no wallet on Robinhood Chain. Fees go to the public donation wallet shown on every coin page, and from there they are converted and donated through WWF's official channels, with receipts published on this site.
Can the liquidity be removed?
No. On the curve the ETH is held by the coin's own curve contract and can only leave through sells. At graduation it goes into a Uniswap v4 pool whose position is held by the pons launch locker, which has no withdrawal function and no owner.
What if a coin never graduates?
It simply keeps trading on the curve. Holders can sell back to the curve at any time; nothing is locked or lost.
Who is pons?
pons v2 is an open-source launch protocol deployed on Robinhood Chain (ponsfamily.com, code on GitHub). Echobase calls its public factory; it holds no special access. pons keeps a 1% protocol fee on curve trades and a share of the post-graduation hook fee, and runs the keeper that sweeps fees and finishes graduations.
Can the 2% fee be changed, or sent somewhere else?
Not by a creator and not by Echobase. The rate and the recipient are set by Echobase's launch contract on every launch, and pons only lets the current recipient, the donation wallet itself, transfer that role. Plain wallet-to-wallet transfers are free.
What does launching cost?
The pons launch fee, 0.0005 ETH, plus gas on Robinhood Chain. No liquidity is required, but pons fills the creator's first buy inside the launch transaction, so an opening buy of at least 0.0001 ETH is part of every launch. It is filled at the opening price, exempt from the anti-snipe tax.
Is this the same as llmtokens.fun?
Same launch protocol, pons v2, so the curve, the 4.2 ETH graduation, the locked Uniswap v4 pool and the anti-snipe tax behave identically. What differs is the fee: there the creator tax funds an AI compute pool; here it is locked to the WWF donation wallet.
Why is my coin not on GMGN or DexScreener yet?
Those trackers read DEX pools, and a coin on the curve does not have one until it graduates. Trackers that index pons curves show it from the first block; the rest pick it up when the Uniswap v4 pool is created at 4.2 ETH.
How is the market cap at launch decided?
By the curve's 1.68 ETH virtual reserve against the 1,000,000,000 supply: about 1.68 ETH. Every buy moves it up along the constant-product curve.
Where is my coin image stored?
On IPFS. The launch form resizes it and the site pins it through its own server, then the ipfs:// address is written into the token by pons together with the name, description and links, so it is part of the coin's immutable on-chain metadata. You can also paste the URL of an image you host yourself.
