Samsung Wallet Adds USDC on Sui: What US Galaxy Users Get
Samsung Wallet is adding USDC on Sui for US Galaxy users: USDC only, no SUI or gas needed, custody by Bastion and Coinbase, and when it actually goes live.
Samsung Wallet is adding USDC, and Sui is one of the blockchain networks behind it. The Sui Foundation announced on 8 October 2026 that eligible Galaxy users in the US will be able to hold and send USDC on Sui from Samsung Wallet, with no network fee and no need to hold the SUI token.
The launch is US only and USDC only: the SUI token itself is not supported in Samsung Wallet. This guide explains what was announced, when it actually goes live, who holds the money, what it costs and what you can do with USDC on Sui once it is in a wallet you control.
What Samsung and Sui announced
Samsung published its own announcement on its US newsroom on 7 October 2026, and the Sui Foundation followed a day later with the Sui side of the story. The key points, with the source for each:
| Item | Detail | Source |
|---|---|---|
| Region | US first; other markets later, subject to local regulation | Samsung, Sui Foundation |
| Asset | USDC only at launch; the SUI token is not supported | Sui Foundation |
| Devices | Up to 82 million US Galaxy devices compatible with Samsung Wallet | Samsung |
| Network fee | $0.00 at the network level on Sui; no SUI needed for gas | Sui Foundation |
| Samsung fee | None for USDC sent to external wallets; bank transfers carry fees | Samsung |
| Eligibility | US residents aged 18+, Samsung Account, Android 13 or later, identity verification and biometrics | Samsung |
| Custody | Accounts run on Bastion; Coinbase is sub-custodian via Coinbase Prime Vault | Samsung |
| Timing | "The last week of October" 2026 | Samsung |
The device figure is a ceiling rather than a user count. Samsung's footnote says it "reflects the number of Galaxy devices in the United States that are compatible with Samsung Wallet", and each user still has to register and pass verification.
Is it live yet? The rollout-timing question
Reports disagree on this, so here is what each source says. Samsung's own release states that the stablecoin wallet "will be available in the last week of October across eligible Galaxy devices". The Sui Foundation's post also uses the future tense and gives no launch day. Blockhead, writing on 9 October, said Samsung Wallet "now supports" USDC on Sui, while The Defiant headlined it as arriving in late October.
We treat Samsung's date as authoritative because Samsung runs the feature. As of 20 October 2026 we could not confirm that it is live for the public. If you have an eligible device, check the Samsung Wallet app from the last week of October.
How USDC in Samsung Wallet works
This is not a self-custody crypto wallet. Samsung says it is removing the need to install crypto apps, create wallets or manage private keys, and the trade-off is that someone else holds the coins.
- Accounts and custody. Samsung's release says stablecoin accounts "run on Bastion", a stablecoin infrastructure firm with a New York trust charter, and that Coinbase acts as sub-custodian, safeguarding all USDC in Samsung Wallet through Coinbase Prime Vault. Samsung adds that it "is not a bank, money transmitter, or digital asset custodian and does not hold customer funds".
- Verification. You need to register, pass identity verification and set up biometric authentication. That is the same kind of KYC check other regulated stablecoin and exchange accounts run, often through specialist providers such as iDenfy.
- Buying. When you tap "Buy Stablecoin", USDC is the default dollar stablecoin.
- Sending. You can send USDC to compatible third-party wallets or exchange accounts "internationally in seconds" with no Samsung fee, though the receiving platform may charge its own.
- Bank payouts. You can send money to eligible bank accounts in more than 60 countries, paid out in local currency. Fees apply and vary by country and amount, and they are shown in the app before you confirm.
Samsung says paying with stablecoins online or by tapping a Galaxy device in a shop "may" follow later. That is a possibility, not a launched feature.
Why Sui, and what "no gas" means
Every transaction on Sui normally needs a small amount of SUI to pay for gas. According to the Sui Foundation, gasless stablecoin transfers went live on Sui mainnet in May 2026, so a USDC transfer costs $0.00 at the network level. That is why a Samsung Wallet user can move dollars without ever holding SUI.
USDC itself has been issued natively on Sui by Circle since the mainnet launch on 8 October 2024. As of 20 October 2026, DefiLlama tracks about $345 million of USDC on Sui, out of roughly $538 million in dollar stablecoins on the network. Samsung's distribution could add many new holders, but only if people actually sign up.
Samsung names more than one network partner. When you send USDC out of Samsung Wallet, pick the Sui network only if the receiving wallet or exchange supports USDC on Sui. Samsung's terms say that compatible wallets are those supporting USDC on a network Samsung Wallet supports, and sending on the wrong network can cost you the funds.
For the wider picture of dollar tokens as payment rails, see our guide to stablecoin payments in 2026 and the GENIUS Act explainer, which covers the US federal stablecoin law. Samsung says it is launching "following the establishment of a regulatory framework for stablecoins".
What you can do with USDC on Sui beyond Samsung Wallet
Samsung Wallet is built for holding and sending dollars, not for DeFi. If you move USDC to a self-custody Sui wallet, you take on the job of securing your own keys, and the Sui DeFi ecosystem opens up. Our best Sui wallets of 2026 guide compares the options. You will need a little SUI for gas inside most DeFi apps, because the gasless feature covers plain stablecoin transfers.
JewelSwap runs several stablecoin products on Sui. None of them is part of Samsung's service, and all carry smart-contract and market risk:
- Scallop suiUSDT–USDC farm. A leveraged stablecoin farm built on Scallop, at sui.jewelswap.io/farm/scallop/0. Our Scallop leveraged farming guide explains how it works and what can go wrong.
- Ember Loop (beta). A JewelSwap Labs vault that turns USDC into Ember's eEARN and borrows against it on Suilend. It is unaudited and is not available to US or UK residents, so most Samsung Wallet users cannot use it. See how Ember Loop works.
- NAVI Loop (beta). A same-asset loop on NAVI for USDY and USDSUI rather than USDC, also unaudited and capped during the beta. See the NAVI Loop guide and the Ember Loop vs NAVI Loop comparison.
Returns on all of these change constantly and are not guaranteed, so we do not quote them here. Check the live figures in the app and read the risk sections before depositing. For a general primer, our guide on how to earn yield on stablecoins covers the main approaches and their risks.
What to keep in mind
- Custodial means counterparty risk. Your USDC sits with Bastion and Coinbase, not in a wallet you control, and the service is subject to partner terms.
- USDC is not a bank deposit. It is a stablecoin backed by Circle's reserves, and stablecoins can briefly trade away from $1. Our explainer on stablecoin depegs covers past cases.
- Fees still exist. Bank payouts carry fees, and the receiving platform may charge on its side.
- Dates can slip. Until Samsung confirms the switch-on, treat late October as a target.
Frequently asked questions
Can I hold SUI in Samsung Wallet?
No. The Sui Foundation says USDC is the only supported asset at launch and the SUI token is not supported in Samsung Wallet.
Do I need SUI to send USDC from Samsung Wallet?
No. Sui's gasless stablecoin transfers, live on mainnet since May 2026, mean a USDC transfer costs $0.00 at the network level, so you do not need to hold SUI.
When will USDC on Sui be available in Samsung Wallet?
Samsung says the last week of October 2026 for eligible US Galaxy devices. Some outlets reported it as already live in early October, but as of 20 October 2026 we could not confirm a public launch.
Who can use USDC in Samsung Wallet?
Eligible US residents aged 18 or older with a Samsung Account, on a compatible Galaxy device running Android 13 or later, who complete registration, identity verification and biometric setup.
Is Samsung Wallet's USDC self-custodial?
No. Samsung says the accounts run on Bastion and Coinbase safeguards the USDC as sub-custodian through Coinbase Prime Vault. Users do not manage private keys.
Can I use USDC from Samsung Wallet in Sui DeFi?
Only after sending it to a self-custody Sui wallet that supports USDC on Sui. From there you can use Sui DeFi apps, which carry smart-contract and market risk and usually need a little SUI for gas.
