Everything you need. Nothing you don’t.

ArcMiner is an idle mining platform that pays out in USDC on Arc, Circle's stablecoin network. A virtual rig accrues USDC for every hour it runs. You collect what it has earned and withdraw it on-chain to any Arc wallet.

There is no token to buy first, no hardware to run, and nothing to pick. Every rig mines the same asset from the same funded pool at the hourly rate set by its equipment tier.

USDC is USD Coin, the dollar-backed stablecoin issued by Circle. On Arc it is also the network's gas token, so the balance you mine, the balance you withdraw and the balance that pays for the transfer are all the same asset.

Tier rates are a platform reward schedule, not a yield or an interest rate. They hold while the pool has funds and can be changed by the operator.

1. Create an account with a password. Your browser generates an Arc wallet locally and sends only its public 0x address to ArcMiner.
2. Download your wallet backup and store the private key somewhere safe. Confirm the backup before continuing.
3. Open your workspace and press start. Your Feather rig begins mining USDC immediately.
4. Server-confirmed time drives accrual. Pending USDC grows every second the rig is running, whether or not the tab is open.
5. Collect pending USDC into your available balance whenever you like, or pause the rig to bank it automatically.

Pending counters estimate accrual between refreshes. Collection always uses server-confirmed balances.

The Feather is included and mines 1.50 USDC per hour. Each permanent upgrade raises your rig to a fixed, higher hourly rate. Higher tiers require the preceding equipment tier.

Paid upgrades are settled in USDC on Arc. Send the exact amount to the ArcMiner upgrade wallet, then submit the transaction hash on the equipment page for verification. Your equipment changes after review; do not send a duplicate payment while waiting.

Every USDC mined on ArcMiner comes out of a single, pre-funded reward pool. The pool started at 1,000,000 USDC; 1,000,000 USDC remains. When the pool is exhausted, mining pauses until it is topped up.

Equipment purchases and the 0% withdrawal tax contribute to the treasury that funds the pool and settles withdrawals. Funding is not a guarantee of solvency or returns: pool capacity, treasury liquidity and payout services all affect availability.

Collect moves pending USDC into your available balance. The withdraw page sends available balance on-chain to any Arc (0x) address you choose, with your own mining wallet pre-filled.

There is currently no minimum withdrawal. Every withdrawal carries a 0% withdrawal tax that stays in the treasury: request 100 USDC and 100.00 USDC is sent on-chain. The form shows the tax and the net amount before you confirm. Treasury checks and network availability still apply.

A submitted request may be processing rather than settled; the ledger in your workspace shows its status and links the Arc transaction once it lands. Until settlement, a mining balance is a running tally, not money in your wallet.

The Arc wallet created at signup is a standard EVM account. Its private key never leaves your browser; ArcMiner stores only the public address. You can import the key into any EVM wallet that supports custom networks and add Arc using the details published at arc.network .

• Never share a private key or password, including with support. Anyone with your private key controls your wallet.
• ArcMiner does not store your private key and cannot recover a lost backup.
• Reward rates, pool funding, minimums and availability can change. Mining may pause when the pool, treasury or payout services are unavailable.
• Upgrades raise your rig's hourly rate. They do not guarantee any return.
• A 0% withdrawal tax is retained by the treasury on every payout. The rate can change.
• Mining is a platform reward schedule. It is not a deposit, not interest, not yield, and this material is not investment advice.
• On-chain transfers cannot be reversed. Verify the destination address and network each time.
• ArcMiner is independent and not affiliated with Circle or the Arc Foundation.
