The US-First Alternative to Airwallex

Who Slash is for — and who it isn't

Choose Slash if your operations are US-first. Most money in and out is USD. You want a business account that pays you back: yield on idle cash, cashback on card spend, FDIC² coverage that scales with your balance, a developer API.

Stay with Airwallex if you genuinely need cross border. You collect in EUR, GBP, AUD, SGD across 70+ countries. You move multi-currency balances between entities. Airwallex was built for that job and Slash isn't replicating it.

Most US founders looking at Airwallex don't actually need the multi-currency machine — they need a modern business account that doesn't leak value.

Four reasons US founders switch from Airwallex to Slash

1. Yield and cashback Airwallex doesn't match

Slash pays high-yield treasury¹ on idle balances and unlimited cashback³ on corporate card spend (Pro plan). Airwallex offers a yield product on USD balances, and its borderless corporate card doesn't offer cashback at all. Over a year of USD operations, that gap compounds.

2. FDIC² coverage measured in hundreds of millions

Slash sweeps deposits through Column N.A. (Member FDIC²) and IntraFi's network of 800 partner banks, extending FDIC² coverage into the hundreds of millions per account. Airwallex partners with Community Federal Savings Bank (Member FDIC²) for US issuing — FDIC² coverage applies at the standard per-depositor limit.

3. Stablecoin on/off ramps, built in

USDC and USDT move in and out of your Slash account the same way ACH and wires do. Airwallex has not released stablecoin rails. If your vendors, contractors, or treasury operations touch digital dollars, Slash handles the full payment flow on one platform.

4. A developer-first API

Slash ships a full read-and-write API — create accounts, issue cards, move money, pull transaction data. Airwallex markets embedded finance APIs aimed at platforms and marketplaces. Slash's API covers the primitives a US operator wires into their own finance stack.

Understanding Airwallex

Airwallex is a global financial technology company headquartered in Melbourne, Australia, with a dual headquarters in Singapore. Founded in 2015, it grew into one of the region's best-known fintech companies before expanding into the US, UK, Europe, and Hong Kong. It serves startups, SMEs, and enterprises — global businesses that send, accept payments, and convert currencies across borders without paying the exchange rates a traditional bank would charge.

What Airwallex does well. Airwallex's core services are global payments, foreign exchange, cross border transfers, and multi-currency business accounts for global businesses. Its borderless platform lets a company open local receiving accounts in 20+ currencies — USD, EUR, GBP, AUD, SGD, and others — across 70+ countries, then send international transfers to 150+ countries in 60+ currencies. FX rates are priced at interbank plus 0.5% on major currencies (1% elsewhere), which undercuts most legacy banking and traditional banking options on cross border wires. Airwallex also offers a payment gateway to accept online payments, a borderless corporate card, expense management tooling, bill pay, and Xero and QuickBooks integrations. For e-commerce, SaaS, and marketplace operators collecting in multiple currencies, those payment services are genuinely strong.

Where Airwallex fits less well for US-first operators. Airwallex is not a US-chartered bank. It's a payment platform partnering with a US local bank — Community Federal Savings Bank — for card issuing and FDIC² coverage. If most of your money lives in USD, the cross border infrastructure you're paying for isn't driving your P&L. Meanwhile features a USD-first business account prioritizes — high-yield treasury, card cashback, expanded FDIC² sweep coverage, stablecoin rails — either aren't offered or aren't the product's focus. Airwallex also pushes volume customers onto paid plans (Grow at $12/user/month, plus an Accelerate tier), so costs climb as your team grows.

The Slash angle. Slash is built US-first: FDIC² coverage in the hundreds of millions via Column N.A., unlimited cashback on the corporate card (Pro), high-yield treasury, stablecoin on/off ramps, and 5,000+ customers running $5B+ in annual card spend across the platform. Not competing on cross border — competing on being the business account a USD-first operator actually needs.

Switching is straightforward

1. Apply in under 10 minutes. Work email, EIN, a few onboarding questions.

2. Move payroll and vendors over. Export transaction history from Airwallex to copy ACH payees into Slash.

3. Issue a card and start earning cashback. Virtual cards provision quickly. Physical cards ship after approval. Cashback³ applies on Pro.
