Slush Wallet adds Halliday integration to simplify deposits into Sui

Slush Wallet Simplifies Sui Deposits with Halliday Integration

Introduction

Slush Wallet, the official Sui wallet, has 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. This integration simplifies the process of depositing funds into Sui, removing the need for exchanges and manual bridging.

What the Halliday Integration Does

The core feature of the integration is simple to describe. A user holding tokens on another chain can send them towards 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, while swapping means trading one token for a different one.

Benefits of the Integration

The supported network count stands at 25 chains, which covers the cross-chain side of the problem. The integration also removes the need for fiat on-ramps, which typically come with their own fees and verification steps. Users can now pay with credit cards, bank transfers, or Apple Pay, making it easier to access Sui.

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.

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.

Risks and Considerations

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.
