Arcus (arcus.xyz) is a decentralized trading venue that runs spot and perpetual markets from a connected wallet.
There is no account to create and no balance held by the operator, which is the fact that shapes everything else about the referral: attribution is written to your wallet when you arrive through the link, and the discount follows that wallet afterwards.
This guide covers where the referral attaches, what the 5% actually applies to, and what self-custody means for your risk. You can compare it with other deals on our crypto referral codes page.
The fine print
The Arcus referral code is REFERRALLINKS, and it travels inside the link rather than in a field you type into. Open the ReferralLinks link, connect a wallet, and the 5% discount attaches to that address.
There is no sign-up form to complete and your keys never leave your wallet: the discount attaches to the address you connect, and the platform never takes custody of the funds.
What is Arcus, in plain words?
Most decentralized exchanges ask you to choose between two compromises: either your funds stay with an exchange (fast, but you trust the company), or you keep custody (safe, but slower and clunkier). Arcus is one venue that tries to combine the two.
Your wallet stays in control of your assets (trades settle on-chain, so there is no moment when someone else holds your money) while the trading screen offers order books, a chart and a faster order path than a simple swap interface.
The appeal is straightforward: you keep the self-custody guarantees (no withdrawal queue, no account that a company can freeze) without giving up the tools a trading terminal normally provides. What that does not do is remove market risk, and the wallet becomes the security boundary instead of a login.
The deal: 5% off Arcus transaction fees
Sign up through the official ReferralLinks referral link at app.arcus.xyz/ref/REFERRALLINKS and you get 5% off all transaction fees. The discount is not limited to your first trade. It applies to every transaction fee you pay on the platform, for as long as the program runs.
Because decentralized platforms charge a fee on each swap, open and close, that 5% adds up quietly in your favor across hundreds of trades a year. It costs nothing to claim, and it applies to each fee for as long as the program runs.
How the 5% attaches to your wallet
Open the referral link (the code REFERRALLINKS is pre-applied) and connect your Web3 wallet. MetaMask, Phantom, Rabby and most popular wallets work out of the box; if yours is not listed, the walletconnect option covers hundreds more.
There is no sign-up form and nothing to enter manually. The 5% discount attaches to the wallet you connect, the moment you arrive through the link. From there, deposit the asset you want to trade, pick your market and place your first order.
The reduced fee shows up in the trade confirmation, so the first swap is also the check that the referral registered.
Attribution without an account
On a venue with no account record, the referral is attached to the wallet, not to a username. That has one practical consequence worth understanding: the link you arrive on is the whole mechanism.
Connect through a different path later, or connect a second wallet, and that wallet is a new visitor with no referral attached.
It also means the discount is only as portable as the wallet. If you rotate wallets for privacy, expect the fee rate to reset on the new one. If you use a hardware wallet that connects through the same address, nothing changes, because the address is what the platform sees.
Self-custody is the real risk line
A 5% discount on a fee is small, and the thing that can actually cost you money here is the wallet. Nobody legitimate needs your seed phrase, including any support account that claims to be Arcus.
Bookmark arcus.xyz, check the address bar every time, and ignore links sent by direct message: a referral link is a normal URL, so it is also a normal disguise.
Frequently asked questions
How do I claim the Arcus referral discount?
Open the referral link at app.arcus.xyz/ref/REFERRALLINKS and connect your wallet. The code is pre-applied, so the 5% discount attaches to the wallet the moment you arrive.
Which wallets work with Arcus?
MetaMask, Phantom, Rabby and most popular wallets work out of the box. If yours is not listed, the WalletConnect option covers hundreds more.
Is Arcus non-custodial?
Yes. Your wallet stays in control of your assets at all times and trades settle on-chain, so there is no moment when the platform holds your funds.
Does the 5% discount expire?
The discount applies to every transaction fee for as long as the referral program runs, not just your first trade. Referral terms can change, so check the current program details before you commit.
Risks to know before you trade
Always verify you are on the official app.arcus.xyz domain before connecting a wallet. Fake clones of trading platforms are the single most common way traders lose funds; bookmark the real site and check the address bar every single time before you approve any transaction.
Trading crypto involves substantial risk. Decentralized markets move fast and there is no customer support desk to reverse a bad trade. Only trade with funds you can afford to lose, and double-check every wallet signature before confirming it.
Referral terms can change, so it is worth glancing at the current program details on Arcus itself before you commit.

How to check that the Arcus code actually applied
Check on the platform, not on a code list. Open app.arcus.xyz from its own domain, start the sign-up (or the first deposit) and read the confirmation screen before you approve anything.
A referral that registered shows up as one of three things: a reduced fee in the order preview, a rebate line in the account, or a visible referral tag next to your address.
If none of the three is there, stop and reopen the link from this page instead of signing up and looking for a code field afterwards.
Almost every program in this list attaches the referral at registration only; a code typed later, or a page refreshed later, cannot retroactively claim an account that was created without one. This site re-tests each flow by hand and prints the date in the sidebar.
How we test codes describes what that involves.
What happens if the Arcus program changes or ends
Two different things end at two different times. The terms you signed up under usually keep applying to your account while the program runs, and the platform can change those terms with notice, so a rate you earned last month is not a rate you are owed next month.
When a program ends, the code field stops accepting new codes and new sign-ups stop being attributed; existing balances revert to the standard rate on the platform’s own schedule.
Commission already credited is the platform’s obligation to the person who referred you, not something this site can recover or guarantee. If a page here is out of date, it is because the change has not been re-checked yet, not because the number was invented: every figure carries the date it was last confirmed.
