launch a memecoin on Elysium (testnet)
onlybags is a pump.fun-style memecoin launchpad. Anyone can launch a coin in seconds: it starts trading at once on its own bonding curve, priced in HYPE. Creators earn 0.30% of every trade on the curve and a share of the pool fees after graduation. When the curve sells out the coin graduates to the onlybags exchange, with its liquidity locked forever. A 50% launch fee that falls to 1.25% over 10 seconds makes sniping expensive.

Which chains does onlybags support?
Arc (mainnet, priced in USDC) at https://onlybags.wtf/arc; Robinhood Chain (mainnet, priced in ETH) at https://onlybags.wtf/hood; Elysium (testnet, priced in HYPE) at https://onlybags.wtf.
How do I launch a memecoin on Arc?
Open https://onlybags.wtf/arc/create, connect a wallet holding USDC on Arc (USDC also pays the network fee), pick a name, ticker and image, and sign one transaction. Launching is free apart from the network fee. You can optionally buy some of your own coin in the same transaction (the dev buy, capped at 10% of the curve supply). You can also pay with a coin from another chain: Relay bridges it into USDC on Arc first.
How do I launch a memecoin on Robinhood Chain?
Open https://onlybags.wtf/hood/create, connect a wallet holding ETH on Robinhood Chain (ETH also pays the network fee), pick a name, ticker and image, and sign one transaction. Launching is free apart from the network fee. You can optionally buy some of your own coin in the same transaction (the dev buy, capped at 10% of the curve supply). You can also pay with a coin from another chain: Relay bridges it into ETH on Robinhood Chain first.
How much do creators earn on onlybags?
0.30% of every buy and sell on the coin's bonding curve (the trade fee is 1.25%: 0.30% to the creator, 0.95% to the protocol). After graduation the creator keeps earning: on Elysium its pool on the onlybags exchange charges a fee by market cap (up to 1.25%), shared between the creator, the protocol and the pool's liquidity; on Arc its Uniswap V4 pool charges a 1% LP fee, split 30% to the creator and the rest to the protocol (the liquidity is locked in the migrator); on Robinhood Chain its Uniswap V4 pool charges a 1% LP fee, split 30% to the creator and the rest to the protocol (the liquidity is locked in the migrator). Creators claim their fees on their profile page whenever they like.
What happens when a coin graduates?
Each coin has a fixed supply of 1,000,000,000 tokens; 793,100,000 are sold on its bonding curve. The buy that takes the last tokens off the curve graduates the coin in the same transaction: what the curve raised and the remaining 206,900,000 tokens go into a pool at the curve's last price (the onlybags exchange on Elysium, Uniswap V4 on Arc, Uniswap V4 on Robinhood Chain), and that liquidity is locked forever. There is no graduation fee. Before graduation a coin can only be bought from and sold to its curve; afterwards it is a normal, transferable token. On Arc a coin graduates when the curve has raised about 12,161 USDC.
Is onlybags safe? Is it audited?
The onlybags contracts were reviewed internally in several rounds; they have not been externally audited, and they may contain bugs. The protocol owner (a multisig on mainnet) can pause new launches and buys (selling can never be paused) and change the protocol's fee wallets; after a 2-day public timelock it can change the migrator and the curve settings and fees for coins launched afterwards (the full list is in the risk disclosure at https://onlybags.wtf/risk). The owner can't take coins, pooled liquidity or anyone's fees. Memecoins are extremely risky: most go to zero and you can lose everything you put in. Nothing on onlybags is investment advice.
How does onlybags stop snipers?
A new coin starts with a 50% launch fee that falls linearly to the normal 1.25% over 10 seconds, on buys and sells; the part above the normal fee goes to the protocol. Every onlybags coin address ends in ba65, so a copy launched elsewhere is easy to spot. Bots can still buy early: the fee reduces sniping, it doesn't remove it.
Memecoins are extremely risky and usually go to zero. Nothing here is investment advice.
