# Argus Arc Launch > Launch an Arc token on Argus (Portal 8) against any of its 7 quote assets, with the tax-free opening buy, up to 25 Snipe Wallets on the launch's snipe allowlist, Sell / Buy holder cleanup, and creator fees claimed in the quote. - URL: https://docs.sumo.trade/launch-tokens/arc-argus-launch - Markdown: https://docs.sumo.trade/launch-tokens/arc-argus-launch.md - Docs index: https://docs.sumo.trade/llms.txt Sumo supports **Arc Argus** launches on Arc. One `launch()` transaction from your dev wallet creates the token, its own Uniswap V4 tax hook and fee escrow, puts the whole supply into one locked V4 position, and runs the **opening buy**: a single tax-free buy for the dev wallet. Argus takes no bundle (one opening buy per launch), so the rest of your supply comes from **Snipe after launch**: up to 25 Snipe Wallets that Argus lists on the launch's snipe allowlist, so they skip the 3-second opening surcharge. ## Prerequisites Before launching, make sure you have: 1. Token metadata ready: name, ticker, image, description, and social links 2. USDC on Arc (Arc's gas token) for the opening buy, the dev wallet's gas, the snipe buys and the cleanup gas 3. A launch plan: dev buy, snipe share, buy and sell tax, and holder cleanup preference 4. A wallet plan: use ready wallets from private keys, [Wallet Farm](/wallet-farm/overview), or another profile, or create new Arc wallets during the wizard > **Fixed Argus Parameters** > > Argus launch tokens use a fixed total supply of 1 billion tokens with 18 decimals. The pool starts at about $2,500 market cap and bonds at about $45,000 (set by Argus per quote, in the quote's own units). 100% of the fee lanes go to the creator; burn, dividends and liquidity lanes and GitHub / X payouts are not offered yet. ## Launch Flow ### 1. Info Choose **Arc** in the Network field and **Argus** in the Launchpad field, then enter the token and profile details. The image is stored on the token itself (its URL must be at most 512 bytes, which Sumo's image links are). ### 2. Buy Setup | Setting | Description | | ------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Quote Asset** | The asset the pool is priced in: USDC (default), EURC, cirBTC, XAUM, WETH, ARGUS or GBPA, the assets Argus's quote registry admits (no custom quote). USDC is Arc's gas token; for any other quote the launch wallets are funded in USDC and swap it into the quote before the launch (the **funding swap** in the Funding step, with a swap back). Creator fees pay out in the quote. Fixed once the draft is saved. | | **Launch plan** | One bar with the dev buy and the snipe. Default: **40%** = 1% dev buy + 39% snipe. Argus refuses any launch whose opening buy would reach the bond (about 76% of supply). | | **Dev buy** | The opening buy: tax-free, inside the launch transaction, sent to the dev wallet. It is required and must be at least 0.01% of the bond value (4.50 USDC on a USDC launch). | | **Buy Tax / Sell Tax** | 1% to 10% each, default 1% / 1%, fixed for the token's life. Argus adds a 1% base fee to every buy and sell. 30% of every fee goes to the Argus treasury; the other 70% is the creator's. | | **Snipe after launch** | Up to 25 Snipe Wallets (default 25), Burst pacing, 25% max premium, no initial delay, very high gas priority. See below. | | **Token Cleanup Method** | Default **Sell / Buy**: after the snipe ends, the snipe wallets' tokens move to fresh holder wallets by sells and buys on the launch pool. Holder Wallets default to one per Snipe Wallet. | | **CEX Funding** | Funds the launch wallets with Arc USDC cashouts through the standard CEX funding flow. | | **Trading slippage** / **Cleanup slippage** | As on every EVM launchpad; the token's tax is added on top. | ### 3. Wallets | Role | Description | | --------------------- | ------------------------------------------------------------------------------------------------------------ | | **Dev Wallet** | Sends the launch (the hook salt is mined for it), receives the opening buy and is the creator payout wallet. | | **Snipe Wallets** | Up to 25. Each one sends its own snipe buy, so Argus can match it on the allowlist. | | **Holder Wallets** | Receive tokens through the post-launch cleanup. | | **Injection Wallets** | Optional wallets funded for activity after launch. | ### 4. Funding Save the draft before funding. The dev wallet needs the opening buy plus about 1 USDC for gas; each Snipe Wallet needs its snipe budget plus its gas and cleanup reserve. On a quote other than USDC, fund in USDC, then run the **funding swap**: it buys the dev wallet's opening buy and each Snipe Wallet's budget in the quote and keeps their USDC gas. The launch waits until the dev wallet holds its opening buy in the quote. ### 5. Launch Preview 1. **Simulate Launch** - Mines the hook salt, checks it with Argus, and simulates the approval and `launch()` from the dev wallet. 2. **Launch** - Hands the launch to the durable runner: it approves the opening buy, sends `launch()` through Arc's private relay, reads the receipt, activates the profile and starts the snipe. ## Snipe After Launch Argus charges an opening surcharge for 3 seconds from the launch block: 99% in total at second 0, +6.18% at second 1, +0.19% at second 2. Your Snipe Wallets are written to the launch's **snipe allowlist** (at most 25 wallets), which skips the surcharge from the block after the launch block. Sumo starts the snipe only once the launch receipt has landed, so it never trades in the launch block, and every snipe buy sets its minimum output from your max price, so a buy that still met the surcharge would revert instead of filling. > **The allowlist is public** > > Argus stores the allowlist in the launch transaction and on the hook, so anyone can see which wallets were listed for the launch. Listed wallets still pay the buy tax and the 1% base fee. Holder cleanup and the launch fee collection start only once the 3-second window is over. ## Creator Fees The creator share of every fee accrues in the launch's escrow, in the launch's quote. **Claim creator fees** shows the amount and claims it from the dev wallet (the payout wallet), paid in the quote. Sumo takes no cut of the claim. If the payout was moved on Argus to a wallet the profile does not hold, the claim is shown but cannot be sent from Sumo. ## After Launch The profile trades on the launch's Uniswap V4 pool through Arc's Universal Router. Reaching the bond only marks the token as bonded; the pool stays the same.
