How it fits together

• Launch. One transaction deploys your ERC-20, creates its 1% Uniswap V3 pool at a $5,000 market cap and locks the entire supply in it. No bonding curve, no graduation: the coin is tradable on every Arc terminal from its first block.
• Trade. Buys and sells are plain Uniswap V3 swaps. Sidoor's own pages route them through the chain's SwapRouter02 (browser wallet) or the Universal Router (Sidoor wallet); any other terminal can trade the same pool.
• Route fees. The pool charges a 1% swap fee that accrues to the locked liquidity position. Half of it goes to the X handle named at launch (or the creator's wallet), the other half to the Sidoor treasury.
• Claim. The handle's owner signs in with X, gets a Sidoor wallet on Arc, and claims their USDC. No wallet or crypto knowledge needed beforehand.
• Bridge. USDC comes onto Arc from Base or Avalanche through Circle's own rails, and can go back to Base.

Protocol constants

What happens when you bridge

1. Your wallet switches to the source chain and pays the 1% service fee as a plain USDC transfer.
2. You approve USDC once, then confirm the bridge (a burn or a Gateway deposit).
3. Circle attests the burn and mints native USDC to the same address on the destination chain. Sidoor watches the queue and shows each step live on the bridge page.

If a bridge looks stuck

• Arc → Base waits for Circle's attestation. Twenty minutes is normal; nothing is lost while it is pending. The bridge page keeps polling and completes the mint automatically.
• Paste your address or transaction hash into the lookup on the bridge page to see the queue position and the mint status.
• If the fee transfer went through but the burn did not, the bridge page detects the paid fee and lets you resume without paying again.
• Still stuck after an hour? Contact us with the source transaction hash.

You need

• A browser wallet (MetaMask, Rabby, Phantom, Coinbase Wallet, Rainbow, OKX) connected to Arc. The launch page adds the network for you.
• USDC on Arc: $0.50 launch fee, plus whatever you want to dev-buy, plus about 2 USDC temporarily held for gas. A launch uses roughly 5.8M gas; unused gas is refunded, and the page shows the exact amount before you sign.

What the launch transaction does

1. Deploys your ERC-20 with the full 1B supply. The address is chosen so the coin sorts below USDC, which keeps every pool oriented the same way.
2. Creates the coin's 1% Uniswap V3 pool and initialises it at the $5,000 market-cap price.
3. Deposits the whole supply single-sided into a position from that price upward, and mints the LP NFT straight into the Sidoor locker. Nobody, Sidoor included, can ever withdraw that liquidity; the locker can only collect fees.
4. If you set a dev buy, swaps that USDC for your coin inside the same transaction. Nothing can trade before you, so snipers cannot front-run your entry.

The launch page estimates your dev buy exactly: with the whole supply in a single-sided position, x USDC buys L·(1/√P₀ − 1/√P₁) tokens where L = S·√P₀ and √P₁ = √P₀ + 0.99·x/L. In practice: $100 buys about 2% of the supply, $1,000 about 17%, $10,800 pushes the market cap to roughly $50,000.

After launch

• Your coin page shows trades, a live 1-second chart, holders and the fees routed, all read directly from the chain.
• It appears on every Arc terminal and aggregator that indexes Uniswap V3 pools. Bots typically find new pools within a minute.
• Image, description and links are stored off-chain by Sidoor (and pinned to IPFS); the contract itself only knows name, symbol and supply.

1. Fees accrue in the pool. Every swap pays 1% to the coin's locked liquidity position. The position belongs to the locker, so the fees can only ever be collected, never the principal.
2. Collection. Anyone can call collectFees(token) on the launchpad. Sidoor does it automatically (at most every ten minutes per coin, and right before a claim). The contract splits what it collects: 50% to the coin's fee-share wallet, 50% to the treasury.
3. Attribution. When you route to an X handle, the fee-share wallet is Sidoor's fee-bridge treasury and the handle is recorded off-chain. Each on-chain FeesCollected event becomes a ledger row for that handle.
4. Pending vs collected. Balances on the site show both: what has been collected into the ledger and what is still sitting in the pool since the last collection, computed from the pool's own fee accounting, so numbers move the moment someone trades.

If you leave the X toggle off, the fee-share wallet is simply your own address and the 50% is sent to it directly on every collection. The choice is fixed at launch and cannot be changed afterwards.

1. Open the claim page and sign in with X. Sidoor uses X's OAuth 2.0 flow with read-only scopes (users.read, tweet.read); it only learns your handle, name and picture and can never post for you.
2. On first sign-in a Sidoor wallet on Arc is created for your account. Your balance shows everything routed to your handle across every coin, split into collected and pending.
3. Press claim. Sidoor first collects any fees still in the pools, then the treasury sends your claimable USDC to your Sidoor wallet. The minimum claim is 0.01 USDC.
4. From your Sidoor wallet you can withdraw to any Arc address, bridge to Base, or trade coins on the launchpad directly.

Claims are recorded with their transaction hash, and every handle's earned and claimed totals are public on the home page leaderboard.

Arc network

Wallets

Any EIP-1193 browser wallet works; MetaMask, Rabby, Phantom, Coinbase Wallet, Rainbow and OKX are detected by name. Sidoor never sees your seed phrase or private key. Launching asks for one USDC approval to the launchpad; trading asks for approvals to the swap router. Both are standard ERC-20 allowances you can revoke on arcscan.cc at any time.

MetaMask on Arc

• Arc's base fee can move five-fold within minutes. Sidoor attaches explicit fee caps to every transaction so it confirms in a few seconds; if MetaMask shows a transaction as pending for minutes, cancel it in Activity and retry.
• Turn off MetaMask's Smart transactions for Arc and make sure the network uses the RPC above. Relayed transactions have been seen never reaching the chain.
• Arc reserves gas limit × max fee from your USDC before running a transaction. The launch page tells you the exact amount you need, including that temporary hold.

Contracts (Arc mainnet)

The launchpad is an upgradeable proxy owned by Sidoor, used for fee parameters and fixes. The locker is deliberately not upgradeable and has no withdraw function, so no upgrade can ever touch launch liquidity. The launchpad's own tests run every launch, swap and collection against genuine Uniswap V3 bytecode.
