Getting money into Sui, the layer-1 blockchain developed by Mysten Labs, has often required an exchange account, the right token, a bridge, and a measure of patience. Slush Wallet, the official Sui wallet built by the same company, is working to remove most of those hurdles. On October 6, 2026, the wallet announced an integration with Halliday that lets users fund their wallets from 25 different blockchain networks or with ordinary payment methods such as credit cards, bank transfers, and Apple Pay.

The headline change is the removal of the first deposit requirement, long the point where newcomer interest tends to stall.

What the Halliday Integration Does

The core feature is simple to describe. A user holding tokens on another chain can send them toward Slush and receive SUI or USDC directly in their wallet. Behind the scenes, the Halliday integration handles bridging and swapping automatically. Bridging means moving value from one blockchain to another, while swapping means trading one token for a one.

Support for 25 chains 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. According to the announcement, 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 issued by Circle, useful for people who want to hold value without price swings while they decide 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 brief 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, meaning the new deposit flow lands on every surface where users already interact with the wallet.

Why the First Deposit Matters

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.

The flow is designed to serve two audiences at once: newcomers buying their first tokens and experienced holders moving existing assets onto Sui. For the latter group, someone with funds sitting on another network no longer has to route through a centralized exchange or a standalone bridge to try Sui. The wallet does the routing.

Considerations for 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 — services that convert government-issued money into crypto — also typically come with their own fees and verification steps, and users should check the costs presented before confirming a purchase. Those checkout details are the clearest place to see how much friction actually remains.
