3. Does the Changex app have any fees?

Minimum deposits and fees

There are no minimum deposits. The fees that apply are the fees paid to miners and validators to process the transactions on the blockchain.

Withdrawal fees and limits

There are no withdrawal limits – the Changex wallet is completely non-custodial. 

4. Is the Changex app a safe platform?

Many users are concerned about platform safety. How safe is Changex as a crypto platform? Let us take a look.

Physical Presence

Changex has a physical presence. The company that owns Changex app, Olympus Capital, of registration number, is an active company located at 33 Simeonovsko Shose Boulevard, 1700 Sofia, Bulgaria.

No License (for now)

Currently, Changex serves as a non-custodial wallet, and as such, no license is required. However, Changex is currently working on establishing a 100% subsidiary in Lithuania in order to obtain a cryptocurrency exchange and custody license. This will be needed in order to provide centralized cryptocurrency services, crypto-to-fiat, and fiat-to-crypto conversions as well as to become an agent of an Electronic Money Institution for the banking and card in-app services planned according to our roadmap.


The Changex non-custodial wallet uses the framework of a Trust Wallet and builds on top of it.

The Changex app uses standard 12-word mnemonic phrases for private key generation and backup.

The app is by default locked via the lock mechanism on the device it is installed on – pin code, pattern, biometric verification. They are also working on implementing 2FA for an added level of security.

All private keys are kept safely on the blockchain, and nothing is stored on centralized servers, while the HYDRA bridge uses multi-sig verification for all transactions, which makes it highly secure (in light of recent attacks on blockchain bridges).

5. What about counterparty risk?

As with any platform, counterparty risk is always going to be present although the risk at Changex is carefully managed via smart contracts, which guarantee the security and safety of all users involved in the ecosystem.

Changex does not have plans to lend out users’ funds in a centralized manner. The lending market that is mentioned on the Changex website is a central part of the leveraged staking ecosystem, but it operates completely on a peer-to-peer basis.

Users will be able to deposit their stablecoins via the “Lend” option, but this happens via a smart contract and thus Changex has no control.

The user who decides to use leveraged staking taps into that pool of lent stablecoins and takes out a stablecoin “loan” to be used as leverage.

For example, the leveraged staker takes 10,000 USDT from the stablecoin lending pool and uses them (automatically via a smart contract) to buy the same amount of his preferred PoS coin, which is then staked. Part of the staking rewards, around ~9.5%, is repaid to the original lender. So the entire leveraged staking and lending mechanism works on a P2P basis, and Changex controls nothing.

Smart contracts guarantee the security and safety of all users involved in the ecosystem.

With regards to liquidation risk for a leveraged staking position: for a user to have their leveraged staking position liquidated, the leveraged token must fall significantly in terms of price as compared to the staker’s entry point (when the leverage was used). This will close the position and repay the loaned stablecoin amount to the original lender. In order to protect themselves from liquidation, stakers need to monitor their loan-to-value ratio and provide additional collateral for the loan, whenever required.

6. Changex app Product and Features

The Changex platform currently supports sending and receiving supported crypto, DEX swaps, and CHANGE staking.

Changex is integrating a fiat-on-and-off-ramp for quick access and flexible staking pools by the end of Q3 2022. In Q4, a universal crypto card will be released and at the beginning of next year leveraged staking together with full banking functionality.

The Leverage Staking product is not currently online, which means it is not possible to attain a leveraged APR/APY at the moment. However, once it is online users will be able to amplify the yield of any Proof-of-Stake token supported by the app by a factor of 1.2-2x!

Currently, their CHANGE token can be staked, with an APR of approximately 200% and an APY (with daily compounding) of approximately 750%.

How does leverage staking on the Changex platform work?

To understand how Leverage Staking works, we need to mention the open stablecoin market, which will allow users to lend their stablecoins for an APR of approximately 9.5%. When a staker decides to use Leverage Staking, they tap into this stablecoin pool, borrowing funds to buy more of staked assets and increase their holdings, say by a factor of 2x.

Let’s take an example using a HYDRA staking position (~45% base APR) to illustrate:

  • Lenders lend USDT for an interest rate of 9.5% in the Changex app;
  • The staker holds $10,000 worth of HYDRA and borrows $10,000 equivalent of USDC for 9.5% interest (paid to the lender), and using their initial HYDRA amount as collateral;
  • The borrowed USDT is used to buy $10,000 more worth of HYDRA through high liquidity DEX pools;
  • The newly acquired HYDRA, which with the original amount now totals $20,000, is placed into a Leveraged Staking pool, earning its standard interest rate of approximately 45%;
  • The staker repays 9.5% interest to the stablecoin lender (45% – 9.5% = 35.5%), while everything else is benefited as passive income;
  • The final APR on the staked HYDRA amounts to 45% on the original amount + 35.5% on the borrowed amount = 80.5%
  • All this will be possible with just a few clicks, while Changex handles all the heavy lifting through smart contracts in the background.

7. How can you get started with the Changex app

The non-custodial wallet is completely functional and available for download via iOS and Android. Once downloaded, users need to simply transfer any of the supported cryptocurrencies to get started.

The app supports sending and receiving crypto, DEX swaps, and CHANGE staking.

Changex is a non-custodial DeFi wallet which means there are no KYC procedures for creating a new wallet in Changex and using its complete functionality. KYC will be required when Changex initiates its fiat operations and start to issue Debit Cards and IBANs nonetheless.

8. What about Customer Service?

Changex provides online support almost 24/7 on Telegram and their community manager is constantly collecting feedback, which is then forwarded to the developer team for constant improvement.

There is also a “Request a feature” option in the app itself, where users can share their thoughts on the app and request further additions.

Email support is also available: inquiries@changex.io

9. Countries supported by the Changex app

Changex features and products can be availed in all countries except the U.S. and those prohibited by their Policy or Sanction Laws.

According to their terms of service:

“4.2.

10. Our Verdict on the Changex app

Although the platform is still new on the market, Changex is run by experienced entrepreneurs who seem to be doing all the right things that are necessary to build trust among users. We are also very excited to learn about the platform’s leverage staking functionality, which is due to come online next year.

At the moment, we can only fault Changex for not having a license as well as the lack of crypto-to-fiat and fiat-to-crypto conversions on its platform, although to be fair it is a non-custodial platform.
