Memecoin sniper and copy trading bots

A sniper bot buys a new token in the first moments it can be traded. It watches for a launch, such as a new pump.fun coin on Solana or a new liquidity pool on an EVM chain, and sends a buy as soon as the pool exists. The bet is that early buyers get the lowest price and sell into the demand that follows.

Most sniper bots run inside Telegram. You send the bot a token address or set rules, and it buys from a wallet it created for you. Many add auto-sell rules, anti-rug checks and copy trading of other wallets.

A copy trading bot is the slower cousin. It watches wallets that trade well and buys what they buy. For memecoins that usually means a list of Solana wallets with strong recent PnL.

A sniper's edge is measured in blocks. Solana produces a block about every 400 milliseconds. A launch that attracts attention can move several multiples in the first few blocks, so a bot that lands its buy one second late may pay many times the first buyer's price.

That puts snipers in a different business from most trading bots. They pay priority fees so their transaction lands first, and they submit before anyone has time to look at the token.

The price of speed is judgment. A bot that buys in the first block can't wait to see whether the deployer holds most of the supply or whether the pool's liquidity can be pulled. It buys every launch that matches its rules, including the ones that fail.

A Telegram trading bot usually creates a wallet for you and signs trades from its own servers, so it can act on a chat message in milliseconds. Whoever controls those servers can move what's in the wallet. Two incidents show what that means in practice.

The pattern holds beyond those two. A bot that can sign instantly from a chat command holds a signing key in a place you don't control, and its security is the security of its servers, its chat integration and its contracts. Keep only trading money in such a wallet, revoke router approvals you no longer use, and withdraw profits.

Circuit bots trade memecoins through swaps and read on-chain activity through Circuit's data. From the watched wallets, swaps and data commands references:

A swap takes its price from a live executable quote. Each swap has a default slippage of 1% and a minimum output floor that the route must guarantee. Every bot starts in paper trading, where swaps fill at the live executable quote and pay network fees from about $10 of simulated gas.

Circuit is the wrong tool for first-block sniping, and it's better to say so plainly.

• No same-block buys. A bot sees a launch or a watched wallet's trade after it lands, then requests a quote, and Circuit prepares, signs and submits the swap. That takes seconds. A first-block sniper works in milliseconds.
• No mempool access or bundles. Bots don't see pending transactions and can't pay to order their transaction ahead of others.
• No resubmits. A swap that fails or times out is never resent. Same-chain swaps have a 30-second lifecycle deadline, and a submitted swap stays pending until the chain settles it.
• Routes decide what's tradable. A bot can buy a token only if one of Circuit's swap routes quotes it. A brand-new token with no routed pool can't be bought until a route picks it up.
• Continuous bots are limited. Each user can keep three continuous bots running, and the Solana transaction read is limited to 20 calls a minute per account.

What fits is everything a few seconds don't ruin: copying wallets with your own size and exits, buying tokens whose volume is already rising, and selling into targets.

Copying is never instant, and the delay has a price. Say a watched wallet buys a pump.fun token still on its bonding curve at $0.00010. Your bot receives the transaction a few seconds later, quotes and fills at $0.00013 because other buyers piled in. The leader later sells at $0.00015.

pump.fun's fee page lists 1.25% on bonding curve trades as of October 2026. Apply it on both sides of a $100 copy:

The leader made 50% and the copy made 12.5%, before network fees. If the leader had sold at $0.00013, the copy would have lost money on fees alone. A copy bot that skips any trade where the price has already moved more than a set share, say 15%, from the leader's fill avoids the worst of these.

Circuit screens tokens that show up in wallets. It checks them against CoinGecko listings, the Uniswap default token list and Jupiter's verified tokens, and queries GoPlus for honeypot, airdrop scam and counterfeit flags. Tokens that fail, or whose names carry links or fake verification badges, are treated as spam and aren't valued in your balance.

That screen protects what you see. It doesn't decide what a bot buys. A memecoin bot needs its own filters before every buy.

Write these numbers into the spec and the Builder turns each into a setting.

A spec for the Terminal:

"Every hour, pull FOMO's top 30 traders for the last 7 days and watch their Solana wallets. When one of them buys a token, check its one-minute candles. Buy $20 of it if the last candle's close is no more than 15% above the price the trader paid and the token traded on at least 30 of the last 60 minutes. Hold at most 8 tokens. Sell half at +60% and the rest at +150%, or everything at −35%. Never buy the same token twice in a day. Log every buy, skip and sell with the reason."

Run it in paper trading first. Swaps fill at the live executable quote there, so you see the real cost of arriving seconds late. The copy trading guide covers copying Hyperliquid perp traders, which works the same way on perps.

Bots run on a wallet you create in Circuit or import by private key. Circuit keeps the signing key in a hardware enclave, and bots never see it. A bot requests typed actions through Circuit's SDK, and Circuit signs only under the permit you sign with your passkey when you start the bot.

You can export the private key from Settings at any time. Pause, resume or stop any bot whenever you want. Stopping leaves your positions and resting orders in your account, and you close them from Terminal.

Circuit charges no fees today and adds no builder fee to Hyperliquid or Polymarket orders. You pay the venue's trading fees, network gas and any bridge or routing fees, and each prepared action's review shows the costs it reports before you confirm. Today's terms make no commitment about future fees.

What is a memecoin sniper bot?

A bot that buys newly launched tokens in the first blocks they trade, betting that early buyers get the lowest price. Most run in Telegram and sign from a wallet the bot creates and controls.

Are Telegram trading bots safe?

They carry custody risk because the bot's servers sign for your wallet. In September 2024 Banana Gun users lost $3 million through unauthorized transfers, later refunded, and in October 2023 a Unibot router exploit took about $580,000. Keep only trading money in a bot wallet.

Can Circuit snipe pump.fun launches?

No. Circuit bots react in seconds after a transaction lands and can't buy in the launch block. They can read one-minute candles for fresh pump.fun tokens and buy once a swap route quotes the token.

How does memecoin copy trading work?

A bot watches wallets that trade well and buys what they buy, scaled to your capital. On Circuit a continuous bot can watch up to 100 Solana wallets and receive each of their trades within seconds, then apply your own filters, size and exits.

Can I paper trade a memecoin bot?

Yes. Every Circuit bot starts in paper trading, where swaps fill at the live executable quote and pay network fees from simulated gas, so you see the real cost of arriving after the wallet you copy.

What is the best memecoin copy trading bot?

One whose rules you can read and test. Check who holds the signing key, whether you can cap position size and set exits, and how it handles the delay between the leader's buy and yours. Paper trade it before using real money.
