Sling

Sling on this page means Sling Money, the cross-border payments app from Avian Labs. It is unrelated to Sling TV or the Sling staff scheduling tool. Sling Money renamed itself Morse on 15 April 2026, and sling.money now redirects to morsemoney.com.

Morse is a money app that runs on stablecoins, which are digital tokens pegged to a currency such as the US dollar. You add money, the app holds it as a stablecoin on Solana, and you can send it abroad in seconds, spend it with a Visa card, or cash out to a local bank. The company says it works in more than 150 countries. Morse has no token of its own.

How Sling Money (Morse) works: stablecoin transfers on Solana

Morse turns the money you add into a stablecoin, moves that stablecoin over a blockchain, and turns it back into local currency for the person receiving it. You see dollars, euros or pesos in the app. The blockchain part stays out of sight.

Say you are paid 1,000 US dollars by a client and want to send some to family in Mexico. The dollars land in your Morse balance as a dollar stablecoin. You send to another Morse user and the transfer settles on Solana in seconds. Your family can keep the balance, spend it by card, or withdraw pesos to a Mexican bank.

The stablecoins have changed over time. Sling's dollar balance launched on Pax Dollar (USDP) from Paxos USDP$0.996-0.5% in April 2024, according to the company blog. European users moved to EURC, the euro stablecoin from Circle USDC$1.000+0.4%, in spring 2025. Morse's crypto page now says deposits are converted so that "your balance is always USDC", meaning USDC.

If the person you are paying has no account, you can send a payment link instead. Sling called these Sling Links. The recipient opens the link and claims the money without needing the sender's bank details.

Chief executive Mike Hudack explained the product on stage at Solana's Breakpoint conference in 2023 and again in 2024.

Morse accounts, Visa card and global transfers

Morse gives you local account details in US dollars, euros, Mexican pesos and Brazilian reais, a Visa debit card, and transfers to bank accounts and mobile wallets. The idea is one account that can be paid like a local in several countries and spent from anywhere.

The account details matter most if you earn abroad. A freelancer in Kenya can hand a US client American bank details, get paid by ordinary bank transfer, and see the money arrive in Morse. Sling first launched these accounts in May 2025.

The card and the account details run on Bridge, the stablecoin payments company owned by Stripe. A Bridge case study from 23 April 2026 says the card was live in 16 countries at that point and that Morse supports more than 40 currencies. The card is issued by Lead Bank. Morse said in its rebrand post that it aims to reach about a hundred countries with the card during 2026 and to ship physical cards.

Payouts go over local systems where Morse has them, including Pix in Brazil and SPEI in Mexico. Sling launched in Mexico in August 2025.

Morse Invest: tokenized US stocks and ETFs

Morse Invest lets you buy tokens that track US stocks and funds, such as Apple, Nvidia and Tesla. Morse's website lists more than 200 stocks and ETFs and a minimum of 5 dollars. An ETF is a fund that trades like a single share.

You are not buying shares through a stockbroker. Morse's help page on investments says the tokens come from Ondo USDY$1.15+0.3% Global Markets, a separate company. You buy them from other holders on a decentralized exchange, which is a market that runs on a blockchain. The tokens track the price of the real stock.

The same page carries plain warnings. The service is run by Avian Labs Distributed Inc., which Morse says "is not a regulated financial institution". It also says tokenized stocks "are not registered investment products" and that no return is promised. The payments side of the app is licensed and this side is not, so read that page before you use it.

The rebrand post also mentioned ways to earn yield from tokenized US Treasuries. Morse said the timing depends on regulators. We found no launch notice as of 9 October 2026.

Sling Money fees and exchange rates

Sending money to another Morse user is free, and Morse says it converts at the real exchange rate with no markup. Small fees apply when a transfer crosses into a currency that is not local to your account.

Morse's fees page, read on 9 October 2026, lists:

There is one exception worth knowing. Adding money in Zambian kwacha or Rwandan francs costs 4%.

Fees change, so check the fees page before a large transfer. The rate you are quoted in the app is the number to compare against other services.

Crypto deposits and withdrawals: Solana, Ethereum, Bitcoin and more

Morse takes crypto from outside wallets on ten networks and turns it into USDC in your balance. The networks are Solana, Bitcoin, Ethereum, Base, Arbitrum, Hyperliquid, MegaETH, Plasma, Polygon and Tron. The rebrand post in April 2026 said Morse was adding blockchains "beyond Solana".

Solana is still the cheapest route. Morse lists no fee to add or take out stablecoins on Solana, and a wait of about two minutes. Other networks cost more. The crypto page lists a 35 dollar minimum fee to take out Bitcoin, and fees of 3 to 10 dollars on Ethereum.

If you hold USDC in a Solana wallet, Morse is a way to turn it into a bank payout or card spending. If you hold Bitcoin, the fees make small amounts poor value.

Who Morse is for: freelancers, remote workers and families abroad

Morse suits people who earn in one country and live or spend in another. Think of freelancers and remote workers paid in dollars or euros, expats, and families who send money home. Morse names Brazil, Mexico, Argentina, Peru, Kenya, Uganda, Zambia and Indonesia among its markets.

It works best when both people are on Morse, because those transfers are free and take seconds. It also helps if you want to hold dollars while you live somewhere with a weaker currency.

It is a poor fit in three cases. First, if you want a bank account with state-backed deposit cover. Morse says your balance is USDC held on-chain, "not in a bank account". Second, if you want a regulated stockbroker. Morse Invest is not one. Third, if you want a Solana wallet for trading and DeFi. Morse is a payments app and is not built for that.

Is Sling Money safe? Regulation, custody and risks

Sling Money, now Morse, is a real, licensed payments firm with well-known backers. We found no report of a hack or a loss of customer funds. The risks are the ones that come with stablecoins, a young brand, and an investing arm that no regulator oversees.

Morse's website lists three licences. In the US, Avian Labs is a registered Money Services Business. In the EU, Avian Labs Netherlands won a licence under the MiCA crypto rules from the Dutch regulator AFM on 7 April 2025. In the UK, the Financial Conduct Authority cleared Avian Labs to offer crypto services in December 2025, as reported at the time. The site also says the firm holds ISO 27001, a standard for keeping data secure.

Morse says you hold your own funds: "No one else can touch your money, not even Morse." The public pages we read do not explain how your keys are stored, or how you get back in if you lose your phone. Ask support about that before you hold a large balance.

What can go wrong:

• Your balance is a stablecoin. Its value rests on the issuer keeping it fully backed.
• Morse Invest is run by a firm that Morse itself says is not regulated, and the tokens are not registered investment products.
• The card and bank details rely on partners, namely Bridge and Lead Bank. A change at a partner can interrupt service.
• Like any licensed payments app, Morse checks your identity and can hold a transfer for review.
• Blockchain transfers are final. Money sent to the wrong person is hard to get back.

Solana Compass lists no on-chain programs for Morse, so there is no upgrade key for us to check. We found no published outside security audit of the app.

Sling Money vs Wise and other alternatives

The main difference between Morse and Wise is what sits underneath. Wise is a long-running transfer service that works through the banking system. Morse holds your balance as a stablecoin on a blockchain and uses banks only at the edges. Morse is the newer brand and has a shorter track record.

Morse makes most sense in three cases. The person you pay is also on Morse. You want to hold dollars as USDC. Or you want to move money in and out of crypto wallets. A bank-based service may suit you better if you want an older, proven name, or if you do not want to hold stablecoins at all. We have not tested the two on price, so compare the rate each one quotes for your own route.

Other apps on Solana also use stablecoins for everyday payments. Our Lightspeed interview on Flipcash covers one of them.

Avian Labs: team, funding and history

Sling Money was built by Avian Labs. Its co-founders are Mike Hudack, the chief executive, and Simon Amor. The firm's first blog post, "Welcome to Sling", is dated May 2023.

Avian Labs raised 15 million dollars in a Series A round in August 2024. The backers were Union Square Ventures, Ribbit Capital and Slow Ventures. The Block reported that this took total funding to 20 million dollars, counting a 5 million dollar seed round led by Ribbit Capital.

Key dates:

• April 2024: dollar balances launch on USDP.
• July 2024: the Sling Master Plan sets out three stages: person-to-person payments, more activity on-chain, then cards and merchant payments.
• November 2024: US launch.
• March and April 2025: EURC arrives for European users, then the MiCA licence.
• May 2025: US and European account details.
• August 2025: Mexico launch.
• December 2025: UK registration with the FCA.
• April 2026: rebrand to Morse, with investing and a wider card rollout.

The app has shipped most of the third stage of that plan. Morse no longer describes itself as Solana only, but Solana remains its fee-free network for stablecoins.
