Slush Wallet adds Halliday integration to simplify deposits into Sui

Getting money into a new blockchain has usually felt like a scavenger hunt. You need an exchange account, the right token, a bridge, and a little faith.

Slush Wallet, the official Sui wallet built by Mysten Labs, wants to skip most of that. On October 6, 2026, it announced an integration with Halliday that lets users fund their wallets from 25 different blockchain networks or with ordinary payment methods like credit cards, bank transfers, and Apple Pay.

The headline change is the removal of the first deposit requirement. For newcomers, that first deposit has long been where interest goes to die.

What the Halliday integration actually does

The core feature is simple to describe. A user holding tokens on another chain can send them toward Slush and land with SUI or USDC directly in their wallet.

Behind the scenes, the integration handles bridging and swapping automatically. Bridging means moving value from one blockchain to another. Swapping means trading one token for a different one.

The supported network count stands at 25 chains. That covers the cross-chain side of the problem.

The fiat side matters just as much. Users can pay with credit cards, bank transfers, or Apple Pay, which removes the need to open an exchange account just to buy a first batch of tokens.

The result, per the announcement, is that cross-chain funding no longer requires exchanges or manual bridging.

Choosing between SUI and USDC on arrival also gives users a practical option. SUI is the network’s native asset, used for fees and staking. USDC is a dollar-pegged stablecoin, useful for people who want to hold value without price swings while they figure out what to do next.

How Slush got here

Slush has not always been called Slush. It was rebranded from Sui Wallet and absorbed features from Stashed in April 2025.

Since then, Mysten Labs has positioned it as a full-service front door to Sui. The wallet already offers in-app swaps, staking, and seedless onboarding through zkLogin.

Seedless onboarding deserves a quick explanation. Most crypto wallets ask users to write down a seed phrase, a list of words that acts as the master key to their funds. Lose it, and the money is gone. zkLogin is designed to let people set up a wallet without managing that phrase themselves.

Slush runs as a browser extension and as mobile apps on both iOS and Android. So the new deposit flow lands across every surface where users already interact with the wallet.

Why the first deposit matters so much

Onboarding friction is one of crypto’s most stubborn problems. A person might hear about a Sui app, download a wallet, and then hit a wall the moment they need tokens to do anything.

The Halliday integration targets exactly that moment. If a user can tap Apple Pay and end up holding USDC on Sui, the gap between curiosity and actual usage shrinks dramatically.

For existing crypto holders, the cross-chain support addresses a different pain. Someone with assets sitting on another network no longer has to route through a centralized exchange or a standalone bridge to try out Sui. The wallet does the routing.

What this means for Sui and its users

The risks are worth keeping in view. Automating bridging and swapping concentrates trust in the integration doing its job correctly. Users who once saw every step now see only the start and the end, which is convenient right up until something goes wrong in the middle.

Fiat on-ramps also typically come with their own fees and verification steps, and users should check the costs presented before confirming a purchase.
