How to Buy Memecoins on Arc

Arc is a Layer 1 blockchain built by Circle, the issuer of USDC. It uses USDC as its gas token and launches its public mainnet on 16 September 2026.

If you have bought memecoins on Solana or Base, almost everything here will feel familiar. One thing is different, and it is the thing that trips people up: there is no separate volatile gas token to buy first. You hold USDC, you pay fees in USDC, and pools are quoted in USDC. That is the whole adjustment.

This guide assumes you have never used Arc. It covers the wallet, the network settings, getting USDC onto the chain, finding a token, checking it, buying it and keeping track of it afterwards. The checking step is the one worth slowing down for, and it comes before the buying step on purpose.

Step 1: Get a wallet that can hold Arc assets

Arc is EVM-compatible, so any standard Ethereum wallet works — MetaMask, Rabby, or a hardware wallet driven through one of them. You do not need anything Arc-specific. Consider creating a fresh wallet for this, so that a bad approval on a new chain cannot touch anything else you hold. A custodial exchange account will not do: you cannot trade a memecoin pool from one.

Step 2: Add the Arc network

Your wallet needs Arc's network parameters before it can see anything on the chain. Circle publishes the current mainnet values on arc.io and in the Arc documentation; many wallets also carry Arc in their built-in network directory, which is the safer route because you are not pasting values by hand.

Take those values from Circle's own pages or from your wallet's directory. Never from a link someone sent you, a search advertisement, or a reply under an announcement post. A fake RPC entry is one of the cheapest attacks there is on a newly launched chain, and it works because the network is new enough that nobody has the real values memorised.

Step 3: Get USDC onto Arc

USDC is both the gas token and the quote asset, so this single step covers both jobs. Two routes:

From another chain. Circle's Cross-Chain Transfer Protocol moves native USDC between supported chains by burning on one side and minting on the other, so you end up with real USDC on Arc rather than a wrapped representation of it. Move a small test amount first and confirm it arrives before you send the rest.

From an exchange. Check whether your exchange lists Arc as a withdrawal network for USDC; support will vary by exchange and by date. If it does, confirm the withdrawal network dropdown says Arc before you confirm.

Keep a few dollars of USDC aside purely for gas. Spend your entire balance on a token and you will not be able to sell it, because the sell transaction also costs USDC.

Step 4: Find the token

You need the token's contract address, and you should get it from a source that reads on-chain data rather than from a person.

DexScreener, or any chart that indexes Arc pools, will show price, liquidity and volume per pair. The memecentral Arc feed lists every token with a live pool on Arc, newest first, with the launch venue recorded where we can identify it. Arcscan, Arc's block explorer at arc-scan.io, will show you the token contract itself.

Copy the contract address from one of those, not from a tweet. Ticker symbols are not unique and anyone can deploy a token called anything.

How to verify a token before you buy

Run all four of these. They take about three minutes together and they are the difference between a considered purchase and a coin flip.

1. Read the pool, not the price. On the chart page, look at liquidity depth rather than the price line. A pool holding a few thousand dollars will move double digits on a small order, and you will pay that slippage twice — once going in, once coming out. The chart of a thin pool tells you nothing about whether you can exit.

2. Check the contract is verified. Look the contract up on Arcscan and confirm the source code is published and verified. Unverified source means nobody outside the deployer knows what the contract does, including whether transfers can be blocked or more supply minted later.

3. Check what happened to the liquidity. Arc's launch venues treat liquidity differently, and each publishes its own model. Arch states single-sided Uniswap V3 pools against USDC with permanently locked liquidity. Sharc states liquidity is locked forever at graduation. Both read off those sites on 14 September 2026. Bullcheese, built by TrustSwap, locks liquidity through Team Finance's audited contracts rather than burning it, and launches on 16 September 2026, the day Arc's public mainnet opens — per TrustSwap, the operator (Sept 2026). Whichever venue a token came from, find its lock record and confirm it on-chain — a real lock is a position held by a locking contract with an expiry you can read. Where no lock record exists, assume the liquidity can be withdrawn at any moment.

4. Look at who holds it. The holder list on Arcscan tells you who decides the price. If one or two wallets outside the pool hold most of the supply, they can end the trade whenever they choose.

Step 5: Make the trade

Connect your wallet to a DEX interface on Arc. Uniswap is deploying on Arc for mainnet, per Arc's post on the deployment, and aggregator front ends route across the pools that exist.

Paste the contract address rather than searching the ticker. Set a slippage tolerance you have actually decided on — a thin pool will demand a high one, and a high one is an invitation to be sandwiched. If the interface wants 15% slippage to fill your order, the pool is too thin for the size you are trying to trade; the setting is not too low.

Check the quote before signing: the token amount you receive, the price impact, and the gas cost in USDC. Then sign.

Step 6: Track what you hold

Add the token to your wallet using its contract address so the balance displays. Watch the pool page rather than your wallet balance — the number in your wallet is the token quantity, which does not change, while the thing that moves is what the pool will pay for it. Set a price alert if your tracker supports Arc, and decide your exit before you need it.

What can go wrong

Liquidity is removable unless it is locked, and "locked" means a specific contract holding the position until a specific date, not a claim in a Telegram group. Fake tokens copy real tickers. Approval phishing sites mimic DEX front ends closely enough that reading the URL matters. And a thin pool can be exited by the largest holder faster than you can react.

None of that is specific to Arc. What Arc changes is the accounting: your gas and your position are denominated in the same stablecoin, so your cost of trading does not swing while you are deciding.

Bullcheese is a permissionless launch venue. Tokens launched on it are created by anyone, carry no endorsement, and can go to zero. Nothing here is financial advice.

Not financial advice. Memecoins are extremely high risk.
