Risk Disclosure

2026-08-31 read this before bridging or trading

Every transaction you sign is final. Blockchains cannot be reversed, and nothing here can be undone by us or by anyone else. Try a small amount first.

1. Irreversible mistakes

A wrong recipient address, a mistyped amount, or a transaction signed in a hurry can cause irreversible loss. The interface shows every value before you sign, but what you sign is what executes.

2. Arc is pre-launch infrastructure

Arc mainnet is operating before its public launch. Circle can change limits, pause attestation, or alter behaviour without notice. The interface checks, right before each withdrawal, whether Circle has recently signed real burns, and blocks the flow when it cannot confirm this. That check reduces the risk but does not remove it. The timing of attestation and delivery is entirely Circle's.

3. Smart contract risk

The helper contracts are small, open source, covered by an automated test suite, and disclosed, but they are not audited by a third party. Bugs, exploits, or unexpected interactions in any layer, whether ours, Circle's, your wallet, or an RPC endpoint, could result in loss of funds.

4. Interrupted bridge transfers

If your session ends after burning but before collecting, funds are not lost. They remain in Circle's protocol addressed to your recipient, and the Recover screen can finish collection at any time. Burn transaction hashes are stored in your browser, so keep a copy if you clear browser data.

5. Single RPC dependence

Arc has effectively one public RPC endpoint. When it is down the interface may be unable to read chain state, and it will say so rather than guess. This can delay, but does not by itself endanger, funds.

6. Gas is your cost

On Arc, USDC is also the gas token, so bridging your entire balance leaves nothing to pay gas with. Keep a small remainder. Collection on the destination chain also costs that chain's gas.

7. Wallet warnings

Security vendors sometimes flag new crypto domains. This domain was flagged at launch and delisted after review, and residual warnings can persist in individual wallets until their lists refresh. Verification of what this site serves is always available, because the published source is byte-identical to the live page (source).

8. OTC: the premium you pay

On the OTC market you pay above 1:1 for Arc USDC, at a price the seller set. Premiums move with supply and demand. What you pay today can look expensive tomorrow, and nothing guarantees you can resell at any premium at all. Compare the all-in price against simply bridging before you buy.

9. OTC: your listing will read less than you deposited

The 2% fee is collected in Arc USDC out of the delivery, so the vault has to hold it back and your offer lists for slightly less than you put in. This surprises people, so to be plain about it: your payout is not reduced. The buyer's payment reaches you in full, and a deposit sold out at your premium pays you that premium on what you deposited. Terms section 4 works it through with numbers, and the sell form shows your exact payout before you sign.

10. OTC: what the watcher can and cannot do

Deliveries and settlements are executed by an automated watcher (the "keeper") that this site operates. The contracts are written so that the keeper cannot redirect a payment: settlement pays the seller and the fee wallet amounts fixed when the fill was created, refunds pay the buyer in full, and neither contract has a sweep or rescue function. What the keeper can do is act, or fail to act, at the wrong moment. We state the consequences here rather than leave them in the source.

If you are selling, your deposited vault balance is exposed to the keeper key. Releasing a delivery is the keeper's decision, and the Arc contract cannot see the Base payment, so it cannot check the keeper's work. A stolen keeper key could release your deposited balance without a payment ever arriving. Your exposure is capped at what you have deposited and not yet withdrawn, the vault can reach nothing else of yours, and withdrawal needs nobody's permission. Do not leave more in the vault than you are willing to have at risk, and withdraw what is not selling.

If you are buying, your payment sits in escrow until delivery is confirmed, and you can reclaim it yourself after 45 minutes if nothing arrives. The residual case is a stolen keeper key combined with an offer the attacker posted themselves, which could settle open fills without delivering. Exposure is bounded by the 45-minute window and by the total sitting in open fills at that moment.

If the watcher is simply offline, nothing is lost. No new deliveries happen, purchases are not delivered, vault deposits do not sell, and refunds and withdrawals keep working without us.

11. OTC: nothing guarantees a buyer

Listing is not selling. An offer can sit unfilled for as long as no buyer wants it at your price, and there is no market maker behind this book. If you need your Arc USDC out on a schedule, withdraw it from the vault and use the bridge instead of waiting.

12. OTC: the fee can change

The escrow and vault each have an owner address that can change the fee rate and the keeper address, and nothing else. The rate is bounded by an immutable 5% ceiling written into each contract at deployment, which no one including us can exceed. A change cannot take anything you hold, but it can strand a live offer: if the rate is raised while your offer is listed, the vault no longer covers the listed amount plus the new fee, and deliveries against it fail until you relist. A buyer caught by that is refunded after 45 minutes, and your deposit stays withdrawable throughout.

13. Notifications are best-effort

Sale alerts run only while the page is open. Missing an alert never loses funds, it only delays your knowing.

14. No advice, your laws

Nothing here is financial, investment, legal, or tax advice. You are responsible for complying with the laws that apply to you and for any taxes you owe.

If in doubt, move a small amount first and confirm it arrives.
