Samsung Wallet to Send USDC on Solana to 82M US Galaxy Devices

Samsung Wallet will let US users send USDC across borders over Solana from the last week of October 2026. Solana Foundation's announcement came on October 7. It puts the reach at 82 million US Galaxy devices and says fiat on-ramps and off-ramps are built in. Soon afterward Coinbase added that USDC is the first stablecoin Samsung Wallet supports and that Samsung picked Coinbase Prime to hold the balances.

Coinbase's post and the Coinbase Institutional follow-up, both on October 8.

Samsung Wallet's Solana choice fills a July blank

At Galaxy Unpacked in London on July 22, Samsung showed a Samsung Wallet mockup with USDC on it. Decrypt reported that Samsung gave no launch date, no issuer and no blockchain. It also left open whether the feature would be custodial.

Three of those gaps now have answers. Solana is the chain, Circle's USDC the issuer and October the month. Custody comes from Coinbase's institutional account and appears nowhere in the Foundation's text.

Coinbase is no newcomer here. In October 2025 Samsung expanded a deal that put crypto purchases inside Samsung Wallet for 75 million US Galaxy owners, per the same Decrypt report. Now 82 million is cited, and that count is the Foundation's own.

Remittances first for Samsung Wallet users

At launch the Foundation's post describes one use, sending money abroad in USDC. It lists no corridors, fees, transfer limits or ramp providers. More countries are promised later, "subject to local regulatory requirements."

Samsung's own voice in the post is a quote from Woncheol Chai, who heads the digital wallet team in its mobile business. He speaks of making stablecoins easier for Galaxy users. Solana, he says, "helps us bring that experience to Samsung's scale." His quote repeats no number.

Solana's stablecoin figures against DefiLlama

Per the Foundation, stablecoin supply on Solana is up nearly 20% over a year. It also says the network handled more than $5.25 trillion of stablecoin volume in 2026. DefiLlama's chain series reads differently on supply, showing about $16.54 billion on October 8 against $15.43 billion on October 8, 2025. That is a rise near 7%.

Both sources may count different coins, and neither explains its method. That volume claim has no public cross-check here.

USDC is the coin Samsung starts with, and its Solana supply has moved the other way. DefiLlama shows $6.93 billion on October 8, against $7.59 billion on April 8 and $11.0 billion a year earlier. USDT on Solana grew from $2.46 billion to $2.91 billion over the same twelve months. Growth came from other issuers.

Banks are arriving on this chain too. Our report on Solana DvP and JPMorgan's input covers that side. For a chain where one product dominates, see Stellar's stablecoin mix.

What the Samsung Wallet rollout still has to show

Coinbase's own post says only "Available soon in the US," which sits loosely beside the Foundation's October timing. Rollout week is the first test, since Samsung or Coinbase would have to publish corridors, costs and limits by then. Remittance products are judged against existing transfer apps on those three numbers, and the Foundation's post gives none of them.

Supply figures come from DefiLlama on October 8, 2026 and move daily. This is a report on an announcement, not a recommendation on USDC, SOL or any Samsung product.
