Slush Wallet Integrates Halliday for Seamless Sui Deposits

Slush Wallet Streamlines Crypto Onboarding with New Halliday Integration

Funding a new blockchain has historically been a complex undertaking, often requiring users to navigate exchange accounts, acquire specific tokens, utilize bridging services, and possess a degree of optimism. Slush Wallet, the official Sui wallet developed by Mysten Labs, aims to simplify this process significantly. On October 6, 2026, the company announced an integration with Halliday that enables users to fund their wallets from 25 different blockchain networks or through conventional payment methods such as credit cards, bank transfers, and Apple Pay.

A key improvement highlighted is the elimination of the initial deposit requirement. For individuals new to the space, this first hurdle has often been a deterrent.

The core functionality of the integration is straightforward. Users holding tokens on an alternative blockchain can transfer them to Slush, receiving SUI or USDC directly into their wallet. The integration handles the complexities of bridging and swapping automatically in the background. Bridging refers to the process of moving assets between different blockchains, while swapping involves exchanging one digital token for another.

The platform now supports 25 distinct blockchain networks, addressing the cross-chain aspect of the funding challenge. Equally important is the fiat on-ramp capability, allowing users to fund their wallets using credit cards, bank transfers, or Apple Pay. This removes the necessity of opening an exchange account solely to purchase initial tokens. The announcement states that this integration means cross-chain funding no longer necessitates the use of exchanges or manual bridging.

Users are also given a practical choice upon arrival, with the option to receive either SUI or USDC. SUI is the native asset of the Sui network, used for transaction fees and staking. USDC is a stablecoin pegged to the U.S. dollar, offering a way for users to preserve value without exposure to price volatility as they explore the network.

Slush Wallet was previously known as Sui Wallet and incorporated features from Stashed in April 2025, before its rebranding. Mysten Labs has since positioned it as a comprehensive gateway to the Sui ecosystem. The wallet already provides in-app token swaps, staking functionalities, and a seedless onboarding experience facilitated by zkLogin.

Seedless onboarding is a notable feature. Unlike most crypto wallets that require users to manage a seed phrase—a list of words acting as the master key to their funds—zkLogin allows users to set up a wallet without the burden of safeguarding this critical phrase. Losing a seed phrase typically results in the permanent loss of access to funds.

Slush Wallet is available as a browser extension and as mobile applications for both iOS and Android devices, ensuring the new deposit flow is accessible across all platforms where users interact with the wallet.

Friction in the onboarding process remains a persistent challenge in the cryptocurrency space. A potential user might learn about a Sui application, download a wallet, only to encounter a roadblock when they realize they need tokens to perform any action. The Halliday integration directly addresses this point of friction. By enabling users to fund their wallets with USDC on Sui via Apple Pay, the gap between initial interest and actual engagement is significantly narrowed.

For existing cryptocurrency holders, the cross-chain support offers a solution to a different pain point. Individuals with assets on other networks no longer need to route their funds through centralized exchanges or separate bridging services to explore Sui. The wallet now manages this routing process.

However, potential risks associated with these automated processes warrant consideration. The automation of bridging and swapping concentrates trust in the integration’s ability to function correctly. Users who previously had visibility into each step of the process now only see the beginning and the end, which, while convenient, can become problematic if an issue arises mid-transaction. Furthermore, fiat on-ramps typically involve their own fees and verification procedures, and users are advised to review these costs before confirming any purchase.
