Phantom

Swap

Monad

<p>Phantom Wallet is removing two networks from its app. Monad disappears on August 26, 2026, Sui on September 24, 2026. Anyone holding a balance there will no longer see it in Phantom afterwards. That does not mean the funds are gone: the coins stay on their blockchain, and you can reach them from another wallet with the same recovery phrase. You still have to act, because the convenient route through the app is only open until each cut-off date.</p>
<p>Both announcements arrived within a few weeks of one another and affect different numbers of investors. The Monad deadline is the tighter one, while the Sui deadline concerns the older network: <a href="https://cryptoticker.io/en/prediction/sui-price-prediction/" rel="noopener noreferrer nofollow">SUI</a> has been running on mainnet since 2023, whereas Monad only launched its own in November 2025. This article sorts out what happens on which date, which two routes are left to you, and where a simple move accidentally turns into a taxable sale.</p>
<h2 id="phantom-wallet-and-sui-what-ends-on-september-24">Phantom Wallet and Sui: what ends on September 24</h2>
<p>Phantom published the decision on August 24, 2026 at 01:01 UTC through the <a href="https://x.com/phantom/status/2091692255094685806" rel="noopener noreferrer nofollow">@phantom account on X</a>. The wording there says that Phantom and Sui have agreed to end Sui support in Phantom on September 24 and to leave the door open for future cooperation. It comes with an assurance: "Your funds remain safe and fully under your control." Before September 24, the post continues, you can move your wallet to another app that supports Sui.</p>
<p>One distinction regularly gets lost in reports of this kind. <strong>Network support</strong> means that the wallet app displays the balances of a particular blockchain, calculates them, and can sign and broadcast transactions on it. When support ends, that is precisely what ends. The blockchain itself carries on unchanged, and your keys remain valid on it.</p>
<p>The integration did not have a long history. Phantom announced the Sui connection in December 2024 and switched it on on January 29, 2025. Roughly twenty months later, it is over. According to consistent reports in the trade press, this was a joint decision by both sides and not a unilateral removal.</p>
<h2 id="monad-in-phantom-wallet-why-august-26-is-the-harder-deadline">Monad in Phantom Wallet: why August 26 is the harder deadline</h2>
<p>For Monad there is a more detailed primary source. In its <a href="https://help.phantom.com/articles/ending-support-for-monad-in-phantom-38674346854931" rel="noopener noreferrer nofollow">help article on the Monad exit</a>, Phantom names August 26, 2026 as the transition date and writes unambiguously: "Your assets are not lost. They remain on the Monad blockchain and can be accessed using a compatible wallet with the same credentials." Your holdings are not lost, in other words; they stay on the Monad blockchain and can be opened in a compatible wallet with the same credentials.</p>
<p>After the cut-off date, Phantom no longer displays Monad balances and no longer processes Monad transactions in the app. The provider itself offers two routes: swapping the Monad holdings into a network that remains supported before the transition date, or exporting the secret recovery phrase from the settings and importing it into another Monad-capable wallet.</p>
<h3 id="the-fee-waiver-has-limits">The fee waiver has limits</h3>
<p>By its own account, Phantom has waived its in-house fee on cross-chain swaps from native MON to wrapped MON on <a href="https://cryptoticker.io/en/prediction/solana-price-prediction/" rel="noopener noreferrer nofollow">Solana</a> until the transition date. Network fees and trading venue fees still apply, as the help article states. The route is therefore not free, only cheaper.</p>
<p>A <strong>wrapped token</strong> is a representation of a coin on a foreign blockchain: the original is locked, and a tradable stand-in is created on the target chain at a ratio of one to one. For the holder that adds a further party carrying risk, namely whoever administers the lock. If you would rather avoid that risk, take the move to another wallet instead of the swap.</p>

<h2 id="are-your-coins-gone-when-a-wallet-drops-a-network">Are your coins gone when a wallet drops a network?</h2>
<p>No. A self-custody wallet does not hold coins, it manages keys. The balances sit on the blockchain and belong to the address derived from your recovery phrase. If the app falls away, the address remains. What falls away is the convenient interface to it.</p>
<p>This design is the decisive difference from an exchange. When a trading venue delists a token or closes your account, it genuinely holds your coins in custody, and the question becomes one of withdrawal deadlines and, in the worst case, forced liquidation. We have written up the <a href="https://cryptoticker.io/en/crypto-exchange-deadlines-august-2026/" rel="noopener noreferrer nofollow">exchange deadlines currently running</a> separately, and they are sharper than what is at stake here. With Phantom the case is milder: access never ends, only the convenience does.</p>
<h2 id="exporting-your-secret-recovery-phrase-the-route-without-a-transaction">Exporting your secret recovery phrase: the route without a transaction</h2>
<p>Moving to another wallet is the route that triggers no transaction, costs no fee and leaves your tax position untouched. You import the same recovery phrase into an app that supports the network, and you see the same balances there. The coins do not move at all; you only change the window through which you look at them.</p>
<h3 id="what-you-need-to-watch-out-for">What you need to watch out for</h3>
<p>The recovery phrase is the master key. Whoever holds it holds everything attached to it, including the balances on every other network under the same phrase. That is exactly why the export is the most delicate moment of the entire exercise. It belongs on a computer you trust, not in a cloud note and not in a photo. We have set out at length how to store the phrase safely for the long term in our guide to <a href="https://cryptoticker.io/en/store-seed-phrase-safely/" rel="noopener noreferrer nofollow">keeping your seed phrase secure</a>.</p>
<p>If your Phantom wallet manages Solana or Bitcoin holdings alongside Sui or Monad, you have two options. Either you import the phrase into the new app as well and keep using both in parallel, or you set up a fresh wallet with its own phrase for the departing network and transfer the balances there. The second variant is cleaner, but it costs network fees and, for tax purposes, counts as a transfer between your own addresses, so it is not a sale. Which software wallets are candidates for which chains is set out in our <a href="https://cryptoticker.io/en/comparison/software-wallets/" rel="noopener noreferrer nofollow">software wallet comparison</a>.</p>
<h2 id="swap-instead-of-move-what-the-fee-free-exchange-really-costs">Swap instead of move: what the fee-free exchange really costs</h2>
<p>The second route is the swap inside Phantom. It is more convenient because you never leave the app, and for Monad holdings it is exempt from Phantom's own fee until the transition date. Three items remain even so: the network fee of the outgoing chain, the fee charged by the executing trading venue, and the price deviation between the quote on screen and the actual fill.</p>
<p>That last item is readily underestimated. On thinly traded tokens, the gap between the expected price and the realised one quickly eats up more than any fee does. If you hold a larger position, check the price a second time before sending and split the swap when in doubt. On very thin pairs, execution through a regulated trading venue can work out cheaper than the swap in the wallet, simply because more counterparty is available there.</p>
<h2 id="tax-on-a-wallet-change-when-a-move-becomes-a-sale">Tax on a wallet change: when a move becomes a sale</h2>
<p>This is where the two routes part company clearly, and for German investors it is the most important passage in this text.</p>
<p>Moving to another wallet is a non-event for tax. You transfer between your own addresses, or you merely import the key; no disposal takes place, and the holding period runs on unbroken.</p>
<p>The swap is a different matter. An exchange of coin for coin counts, for income tax purposes, as the disposal of the asset given up and the acquisition of the asset received. Under section 23 of the German Income Tax Act, the gain remains tax-free if more than a year lies between acquisition and disposal; within the year, the exemption threshold of 1,000 euros applies to the sum of all private disposal transactions in the calendar year. Once it is exceeded, the entire gain becomes taxable, not merely the part above the threshold.</p>
<h3 id="the-contested-case-wrapping">The contested case: wrapping</h3>
<p>Whether wrapping the same coin onto another chain counts as an exchange is disputed among tax advisers. In economic terms you continue to hold the same thing; in legal terms you receive a different token. That is an assessment rather than settled law, and we are not aware of a supreme court decision on the point. The practical consequence for you: if you would rather avoid that uncertainty, take the wallet export and leave the holding alone. If you choose the swap regardless, record the date, price and quantity cleanly. A <a href="https://cryptoticker.io/en/comparison/crypto-tax-software/" rel="noopener noreferrer nofollow">portfolio and tax tool</a> takes that documentation off your hands, provided you enter the transaction promptly.</p>

  Announced migration deadlines are a gift to fraudsters: the bait arrives dressed as an offer of help.

<h2 id="sui-wallet-alternatives-what-phantom-itself-names">Sui wallet alternatives: what Phantom itself names</h2>
<p>For Sui holdings, the reports on the announcement point to two applications as the destination for the move: Suiet and the official Sui wallet, which now trades under the name Slush. Both are self-custody wallets and therefore accept the import of an existing recovery phrase.</p>
<p>We are not assessing these applications here and make no recommendation. Before importing, check for yourself whether the app supports the derivation scheme of your phrase. If the new wallet shows a balance of zero after the import, the cause is often a different derivation path rather than the holding itself. In that case it helps to reveal further accounts under the same phrase in the settings of the new app before you panic.</p>
<h2 id="phishing-at-the-deadline-why-unsolicited-migration-help-is-almost-always-a-scam">Phishing at the deadline: why unsolicited migration help is almost always a scam</h2>
<p>Every publicly announced deadline is a diary entry for fraudsters. The pattern never varies: a message that quotes the genuine occasion correctly, a tight time frame, and a link to a supposed migration tool that asks for the recovery phrase.</p>
<p>Phantom has given this a paragraph of its own in the help article, writing that the company will never contact you first, will never ask for your secret recovery phrase or your private key, and will never offer to move your funds for you. Any unexpected offer of help with the migration should be treated as an attempted fraud.</p>
<p>That rule carries further than the current case. No reputable provider needs your phrase in order to help you, and no genuine migration requires you to type it in anywhere except into the new wallet app itself, locally on your own device. We have broken down the other markers of such messages using the example of fake <a href="https://cryptoticker.io/en/crypto-exchange-withdrawal-phishing-mica-check/" rel="noopener noreferrer nofollow">withdrawal requests from crypto exchanges</a>. The sheer number of active <a href="https://cryptoticker.io/en/bafin-warnings-crypto-platform-series/" rel="noopener noreferrer nofollow">BaFin warnings about crypto platform series</a> shows how large the field has become.</p>
<h2 id="why-wallets-drop-networks-what-the-retreat-says-about-the-market">Why wallets drop networks: what the retreat says about the market</h2>
<p>Putting this in context means separating the evidence from the interpretation. The evidence is this: Phantom is ending support for two networks within a few weeks, in the Sui case by its own account in agreement with the network team.</p>
<p>The explanation behind it is where interpretation begins. Every additional chain in a wallet costs work permanently: its own node connection, its own signing logic, its own price sources, its own support desk. If usage does not carry that effort, the integration turns into a loss-maker. We are not speculating about orders of magnitude here, because we have no reliable usage figures for individual networks.</p>
<p>For you, one practical consequence follows regardless of which explanation is correct: a wallet's network list is no promise of permanence. It can change, and in the best case you hear about it four weeks in advance.</p>
<h2 id="what-the-case-teaches-about-self-custody-and-hardware-wallets">What the case teaches about self-custody and hardware wallets</h2>
<p>The real protection in this episode is the recovery phrase. It is the reason a discontinued network integration turns into an annoyance instead of a loss. Anyone whose coins sit on an exchange has no such safety net.</p>
<p>For larger holdings, a hardware wallet moves the key onto a device with no internet connection. The software interface then stays interchangeable while the key stays where it is. Which devices support which chains and what they cost is set out in our <a href="https://cryptoticker.io/en/comparison/hardware-wallets/" rel="noopener noreferrer nofollow">hardware wallet comparison</a>. It is worth checking the supported networks before you buy, because compatibility cannot be taken for granted there either.</p>
<h2 id="checklist-what-to-sort-out-by-september-24">Checklist: what to sort out by September 24</h2>
<p>Open Phantom first and see whether you are affected at all. Many users never activated either of the two chains and have nothing to do.</p>
<p>If you find a Monad holding, time is short: only a few hours of room to manoeuvre remain in the app before August 26, 2026. For Sui holdings you have until September 24, 2026, though you should not push it into the final week, because network fees and waiting times tend to climb shortly before a deadline expires.</p>
<p>Note down your balance before the move as well. If a different amount appears in the new app after the import, you will want to know whether a price difference or a wrong derivation path is behind it.</p>
<h2 id="checking-your-phantom-move-what-to-take-away">Checking your Phantom move: what to take away</h2>
<ol>
 <li><strong>Establish whether you are affected and choose your route.</strong> Check your Phantom wallet for Monad and Sui holdings. If you want to keep them, export the recovery phrase and import it into a suitable app; you will find an overview of the candidates in the <a href="https://cryptoticker.io/en/comparison/software-wallets/" rel="noopener noreferrer nofollow">software wallet comparison</a>.</li>
 <li><strong>Settle the tax consequence before you click.</strong> Moving between your own wallets is not a sale, whereas the swap is. Record the date, quantity and price of every transaction, most easily with a <a href="https://cryptoticker.io/en/comparison/crypto-tax-software/" rel="noopener noreferrer nofollow">crypto tax tool</a> that tracks the holding periods for you.</li>
 <li><strong>Secure the key for the long term.</strong> If this case forces you to export your phrase, it is the right moment to reorganise how you store it. For larger holdings the key belongs on a separate device: <a href="https://cryptoticker.io/en/comparison/hardware-wallets/" rel="noopener noreferrer nofollow">hardware wallets compared</a>.</li>
