Are Bamboo, Risevest, Trove and Chaka Halal? (2026): Dollar Apps Examined

None of the four apps is halal or haram as a whole; each is a shelf with permissible and impermissible products on it. Buying a Shariah-screened US stock or ETF through Bamboo, Trove or Hisa (the platform chaka.com now resolves to) is permissible, because you own a fractional share held at a US broker and your return is the company's performance. Bamboo Fixed Returns, Risevest's Fixed Income plan and wallet, Trove's Earn savings and Hisa's wallet interest and vaults all pay a stated return on cash, which their own pages call interest, and those fail. Risevest in particular does not let you choose stocks, so it offers no compliant route at all. The full method is on our is-it-halal hub.

What each app sells, as published on 24 September 2026

The table is drawn from each company's own site and help centre. Two housekeeping points. First, Chaka no longer operates under its own brand: chaka.com loaded the Hisa site when we fetched it, and the Hisa footer states that 'Nigerian equities trading is facilitated by Chaka Technologies Limited', a digital sub-broker licensed by the SEC, 'through Citi Investment Capital Limited'. Second, Risevest's Naira offerings are also 'powered by Chaka Technologies Limited' according to its FAQ, so the same licensed entity sits behind two of the four apps.

SEC Nigeria registration: who is actually licensed

The SEC's own page of registered fintech operators, fetched on 24 September 2026, lists Chaka Technologies Ltd and Bamboo System Technology among its registered fintech firms in the digital sub-broker and related categories, alongside Cowrywise and Wahed. Bamboo's help centre confirms it 'is licensed by the Nigerian Securities and Exchange Commission (SEC) as a digital sub-broker and is also registered as a sub-broker under the Nigerian Exchange Group Limited (NGX) through Lambeth Capital Limited'. Trove's Nigerian business is run by Trove Trading Services Ltd with Nigerian securities 'provided by Sigma Securities LTD, a SEC registered broker-dealer', and its FAQ also names ARM Securities. Risevest states it is 'registered in Delaware, USA and in Nigeria', with its Naira products powered by Chaka's licence; its disclosure page gives a Grand Cayman address for Rise Vest Technologies Limited.

On the US side, Bamboo and Trove's Nigerian customers hold their US accounts at DriveWealth LLC, a FINRA member, and Hisa uses Alpaca Securities LLC. Both brokers are members of SIPC, which protects securities and cash up to $500,000 (including $250,000 for cash) if the broker itself fails. SIPC does not protect you from a stock falling, and none of this says anything about Shariah. It does tell you that the shares you buy are real and held at a regulated custodian, which is the precondition for calling the ownership genuine.

Where interest appears, app by app

This is the part that matters for a Muslim investor, and each company describes the interest product in its own words.

• Bamboo Fixed Returns: 'a fixed-income dollar-denominated investment that gives you up to 7% USD annual returns', with tenors of 30 days to a year, 'your Principal is assured', described as 'Dollar-denominated interest', backed by 'a diversified pool of short and medium-term dollar-denominated fixed-income instruments'. Breaking early can forfeit 'up to 50% of the interest you've earned'. Bamboo's Treasury Bills product is Nigerian T-bills bought at a discount; its help centre shows the interest formula. Both fail.
• Risevest: the Fixed Income plan targets '10% p.a' with 'predictable annual returns'; the Dollar Vault pays '10% p.a' and the Naira Vault 'up to 23% p.a'; the Wallet pays '8% annual returns in USD' with 'interest paid daily'. All four are returns on cash or on conventional fixed income and fail. The Real Estate plan ('US fractional real estate', 'monthly rental income', 14.4% historical) could be permissible in principle, but Risevest does not publish the properties, the financing or any Shariah review, so it cannot be verified.
• Trove Earn: 'NGN Savings: Earn Up to 20% Annual Returns' and 'USD Savings: Earn Up to 5.5% Annual Returns', marketed as 'a consistent yield on your cash'. Trove also lists bonds and Treasury Bills among its instruments. All of these fail; the stock, ETF and mutual fund shelves are judged separately.
• Hisa (Chaka): the Earnings Wallet invites you to 'Earn interest on your USD holdings', and Vaults 'lock funds for passive growth' with a maturity date. Hisa also offers crypto and commodities trading. The wallet interest and vaults fail; our view on crypto is set out separately below.

There is no ambiguity in any of these descriptions. The companies use the word 'interest' themselves, and a guaranteed or targeted return on cash is riba whether it is paid in naira or dollars. The dollar denomination changes the currency risk, not the ruling. If you already hold any of these products, withdraw at maturity, keep the principal, and give the accrued interest away without expecting reward; the same treatment we set out for treasury bills applies.

The permissible core: fractional US stocks and ETFs

Bamboo, Trove and Hisa all let you pick individual US stocks and ETFs and buy fractions of a share. Trove's FAQ notes that DriveWealth allows holdings as small as 0.0001 of a share, and Hisa says you can start with $1. Fractional ownership is still ownership: your account statement shows the quantity, dividends are credited pro rata and the position is sold at your instruction.

What makes a US stock halal is the company, not the app. The screen most Nigerian scholars and funds follow is the AAOIFI one: the business must be permissible (no conventional banking, insurance, alcohol, gambling, pork, adult content or weapons as a core activity), interest-bearing debt must be below 30% of market capitalisation, interest-bearing cash and investments below 30%, and non-permissible income below 5% of total revenue. Our halal stock screening guide walks through the ratios with worked examples, and the halal stocks hub lists screened names. Apply the screen before you tap buy; none of the three apps marks stocks as compliant, and the research, ratings and 'trending stocks' prompts inside them are built without a Shariah filter.

A practical workflow for screened US stocks on these apps

• Fund the naira wallet by bank transfer rather than card; Bamboo charges N150 per transfer above N10,000 against 1.4% (capped at N2,000) on a naira card, and the conversion to dollars happens at the app's rate, which you should compare with the market before large deposits.
• Leave the money in the wallet for as short a time as possible. Bamboo and Trove do not advertise interest on the trading wallet itself; Hisa's Earnings Wallet explicitly pays it, so move funds into stocks promptly and give away any interest credited.
• Buy only names that pass the screen. Prefer a Shariah-screened ETF where the app offers one, because the index provider does the quarterly re-screening for you; check the fund's own Shariah board and methodology document.
• Record dividends. Bamboo credits US dividends to your brokerage account after the 30% US withholding tax; Trove's FAQ explains that the W-8BEN form from DriveWealth is the document for claiming the double taxation relief in Nigeria. You need the gross dividend figure for purification.
• Re-screen every quarter and sell anything that has drifted out of compliance, giving away any gain attributable to the non-compliant period if your scholar requires it.

Risevest cannot fit this workflow because, as its FAQ says, you cannot trade or pick stocks; its Stocks plan is an index of 20 to 30 companies chosen by Rise 'through our algorithms as well as our team of experts' with no Shariah filter disclosed. Wahed, which the SEC lists in the robo adviser category, is the managed option built for this purpose; see our Wahed Nigeria review and the Wahed profile.

Purification: how much to give away and how to calculate it

Even a stock that passes the screen may earn a small amount of non-permissible income, typically interest on the company's bank balances. Lotus Capital's purification page describes the practice: 'investments may nevertheless earn non-permissible income', so the investor identifies the proportionate share and gives it 'out in charity to purify their investments', with calculations 'guided by AAOIFI standards'. Lotus publishes the figure per unit each year for its funds and for companies in the NGX Lotus Islamic Index, and its example is instructive: 'for a N10,000 investment in our Lotus Halal Investment Fund in 2018, only N10.18k is due to be paid in charity for the whole year'.

For US stocks held on Bamboo, Trove or Hisa, nobody publishes the number for you, so the method is manual. Take the company's latest annual report, find interest income (and any other non-permissible revenue), divide by total revenue to get the impure percentage, and apply that percentage to the dividends you received in the year. Many scholars also apply it to realised capital gains; the stricter view is safer. The amounts are small, and the discipline matters more than the kobo. Screened ETFs often disclose a purification ratio per share in their annual Shariah report, which is the easiest route. Give the amount to the poor or to general public benefit, not to a cause you benefit from, and do not count it as zakat.

Crypto, commodities and real estate on these apps

Hisa's crypto shelf (Bitcoin, Ethereum and 'popular digital assets') raises a separate question; our position is in the crypto verdict. Its commodities shelf offers 'direct exposure to global markets like gold, oil and agricultural products', and the permissibility there turns on whether you take ownership of the commodity or hold a derivative or contract for difference; the Hisa pages fetched do not say, so treat it as unverified. Bamboo's and Trove's real estate products and Risevest's US fractional real estate plan are similar: rental income from property is permissible, but only if the property is not financed with interest and the vehicle holds the asset rather than a mortgage-backed instrument. None of the four publishes enough to confirm this, so a Muslim investor should ask for the offering document and a Shariah opinion before committing, or use the vetted routes in our halal real estate guide.

Which app to use, by what you want to do

The decision

If you want to own screened US companies from Nigeria, Bamboo, Trove and Hisa are all usable, and the choice between them is about fees and interface rather than Shariah: Hisa's flat 1% is the cheapest for occasional trades, Trove's subscription suits frequent small buys, and Bamboo has the largest published user base (2.3 million and $600 million in trades, by its own count) and the most detailed help centre. On every one of them, ignore the yield products entirely: Bamboo Fixed Returns, Treasury Bills and naira savings; Trove Earn, bonds and T-bills; Hisa's Earnings Wallet and Vaults. If you want someone else to manage the money, none of the four qualifies today, and Wahed or a Nigerian Shariah fund is the answer. Our dollar investments guide sets out those alternatives, and the halal investing hub lists every vetted platform.

Risevest is the one to be clear about: it is well run and transparent about fees, but it offers no product a Muslim can select without taking interest alongside, and its FAQ confirms you cannot choose the stocks.

Frequently asked questions

Is Bamboo halal for buying US stocks?

Yes, if you choose the stocks yourself and apply a Shariah screen. Bamboo is an SEC-licensed digital sub-broker, your US shares are held at DriveWealth, and you pay a 1.5% commission per trade with a $1 minimum. Bamboo Fixed Returns (up to 7% in dollars, principal assured), Treasury Bills and naira savings are interest products and are not permissible, so leave those tabs alone.

Is Risevest halal?

No product on Risevest can currently be recommended. The Fixed Income plan, Dollar and Naira Vaults and the Wallet all pay stated returns on cash, which Risevest itself calls interest. The Stocks plan is managed without a Shariah filter and the FAQ confirms you cannot pick or exclude companies. The Real Estate plan might be permissible in structure, but Risevest publishes no financing or Shariah details that would let anyone confirm it.

Is Trove halal?

Trove's US stock, ETF and NGX stock shelves are usable with your own screening; US accounts sit at DriveWealth and Nigerian trades go through Sigma Securities or ARM Securities, both SEC-registered. Trove Earn (up to 20% on naira and 5.5% on dollars), bonds and Treasury Bills pay interest and fail. Check any Nigerian mutual fund offered on Trove individually, because most conventional funds hold T-bills and bonds.

What happened to Chaka, and is Hisa halal?

Chaka's website now loads the Hisa platform, and Hisa's footer states that Nigerian equities trading is facilitated by Chaka Technologies Limited, the SEC-licensed digital sub-broker, through Citi Investment Capital. Buying screened Nigerian or US stocks on Hisa at its flat 1% fee is permissible. Its Earnings Wallet pays interest on dollar balances and its Vaults pay a fixed return, so both fail; crypto and commodities need separate judgement.

How do I purify dividends from US stocks bought on these apps?

Find the company's interest income and other non-permissible revenue in its annual report, divide by total revenue, and apply that percentage to the gross dividends you received (before the 30% US withholding tax). Give that amount to charity without expecting reward and without counting it as zakat. For screened ETFs, use the purification ratio in the fund's Shariah report. Lotus Capital's purification page shows how small these figures usually are.

Are fractional shares halal?

Yes. A fraction of a share is a proportionate ownership of the company's equity, held for you by the broker in the same way a whole share is. Bamboo, Trove and Hisa all offer fractions through DriveWealth or Alpaca, and Trove's FAQ cites holdings as small as 0.0001 of a share. The Shariah question is about the company passing the screen, not about the size of your slice.
