memefab is on the GIWA Sepolia testnet. Testnet ETH and tokens have no monetary value. Memecoins can go to zero — play small, for fun.

Trade

Find a token

Discover (the home page) lists tokens. You can sort by:

memefab does not rank by raw volume. A wallet trading with itself creates volume but no net inflow, so wash trading does not move a token up the list. Organic ranking is never sold.

Search matches name, ticker or address. Names and tickers can be copied. The contract address is the only reliable identifier. If a token was not the first to use its ticker, it shows a Not the first $TICKER badge with a link to the original.

Buy and sell on the curve

On the token page, enter an amount and sign.

• Quote. The panel shows tokens out, the 1% fee and any clean-room fee, all read live from the contract.
• Slippage. You set a maximum. If the price moves past it before your transaction lands, the transaction reverts and you keep your ETH, less gas.
• Deadline. Every order expires if it is not mined in time.
• Selling sends tokens back to the curve for ETH, minus 1%. You can sell back to the curve whenever the token is in its curve phase.
• Buy links (?buy=0.01) only fill in the amount box. You still confirm everything.

Fast confirmations (GIWA Flashblocks)

GIWA's sequencer streams each block in small pieces called flashblocks, about every 200 ms, before the full block seals. memefab reads those preconfirmations, so the panel shows Confirmed in 0.4s · Flashblocks ⚡ as soon as your trade is in, and the chart and balances refresh right away.

• How fast. On the GIWA Sepolia testnet we measured about 0.4 s from send to confirmed, against about 1.2 s when waiting for the standard receipt. Times vary with network load and your connection.
• What it is. A preconfirmation is the sequencer's commitment that your transaction is in the next block. The block then seals as usual.
• Fallback. If the Flashblocks endpoint is slow or down, the panel falls back to the standard receipt and simply shows Confirmed. Nothing about your trade changes.
• Your wallet still sends the trade through its own RPC. Flashblocks only speeds up how quickly you see the result.

The last buy that fills the curve is charged only for the tokens that were left. The rest of your ETH is refunded in the same transaction.

After graduation

When the curve sells out, curve trading stops and the token moves to its DEX pool. On the testnet that pool is on Zeoul, and the token page shows a button to it. memefab does not run the DEX. Its prices, fees and interface are the DEX's.

If graduation is ever stuck for 24 hours, anyone can reopen curve trading so holders are not trapped. See Graduation.

Share your position: the fab yield report

On Me, each token you hold has a Yield report button. It prints your position as one picture card: the token, what you put in, what came out plus what you still hold (valued now), and the change in percent. Post it wherever you like. memefab's server reads the numbers from the chain, so a card made on our domain cannot be edited to show other figures. The card only records a past position. It does not show expected returns, and no rewards come with it. On testnet the values are not real money.

Your wallet, your keys

memefab is a website that prepares transactions. Your wallet signs and sends them. We cannot reverse a trade, recover a lost key or move your tokens.
