Frequently asked questions

Swapping on FirstDex

Why do I need SOL to buy Raydium on the Solana blockchain?

To buy or swap tokens like Raydium on the Solana blockchain, you need SOL—the native cryptocurrency of the Solana network—to pay for transaction fees (also known as gas fees). SOL acts as the “fuel” that powers transactions on the Solana network.

Just like SOL is required on Solana, ETH is needed to pay for fees on the Ethereum blockchain, and BNB is required on the Binance Smart Chain (BSC) for similar purposes.

How do I deposit SOL on my wallet?

When you deposit INR into your FirstDex wallet, the equivalent amount of SOL is automatically credited to your wallet within 2 minutes. Once received, you can use SOL to buy any token on the Solana blockchain.

How do I convert SOL to ETH to buy AAVE on the Ethereum blockchain?

Since SOL is native to the Solana blockchain and AAVE exists on Ethereum, you’ll need to use FirstDex’s cross-chain swap feature. This allows you to convert SOL to ETH, which you can then use to purchase AAVE on the Ethereum network

Why can’t I swap 1.5 ETH for a token if I have exactly 1.5 ETH in my wallet?

When swapping ETH for tokens on the Ethereum blockchain, you must leave a small portion of ETH in your wallet to cover the network’s gas fees. These fees are required to process the transaction and are paid in ETH. They fluctuate based on network congestion.

For example, if you have exactly 1.5 ETH, you might need to keep 0.01–0.03 ETH aside for gas fees. Attempting to use the full 1.5 ETH for the swap will result in an error.

How can I verify that my swap was successful?

After completing a swap on FirstDex, you can verify the transaction by checking your Recent Activities section in the app. Each transaction is recorded on the blockchain and can also be independently verified using the transaction hash on blockchain explorers.

We provide direct links to blockchain explorers for each transaction:

Solana: Solscan
Ethereum: Etherscan
Binance Smart Chain: BSCScan

What if I don’t have enough ETH, SOL, or BNB to cover gas fees?

If you don’t have enough of the required network token (ETH for Ethereum, SOL for Solana, or BNB for Binance Smart Chain), your transaction will fail. It’s essential to keep a small balance of the native token in your wallet to cover gas fees.

You can either purchase a small amount of ETH, SOL, or BNB directly through FirstDex or transfer it from another wallet.

Can I use tokens from other blockchains on FirstDex?

Currently, FirstDex supports trading on the Solana, Ethereum, and Binance Smart Chain networks. If you hold tokens from other blockchains, you’ll need to use a bridge or swap service to convert them into a supported token before using them on FirstDex.

How do I connect my wallet to FirstDex?

You can connect your wallet using supported browser extensions or mobile wallets such as MetaMask (for Ethereum and BSC) or Trust Wallet. Make sure your wallet is set to the correct blockchain network—Solana, Ethereum, or Binance Smart Chain—before connecting to FirstDex.

Deposit/Withdrawal

Are their any limits on withdrawals?

There are no limits on withdrawals. Whatever crypto you hold can be converted to INR at any time and withdrawn in full. All withdrawal requests are processed within 24 to 48 working hours.

What are the different fee’s involved in using FirstDex?

If you are depositing or withdrawing through direct bank transfer, there is no extra fee. However, for deposits made through a payment gateway, a 2% transaction fee will apply.

A 1% platform fee is charged by FirstDex on all deposits and withdrawals.

Gas fees are typically minimal on the Solana and Binance Smart Chain networks. However, gas fees on the Ethereum blockchain are comparatively higher due to network congestion and demand.

Can I cancel a withdrawal request?

Once a withdrawal request is submitted, it cannot be cancelled if it’s already being processed. If it’s still pending, reach out tosupport (support@mg.firstdex.in) immediately for assistance.

How long does it take for my deposit to reflect in my wallet?

INR deposits made through payment gateway are usually credited within 2 minutes. Bank transfers may take up to 15 minutes during working hours.

KYC

What are the main reasons for my KYC approval getting delayed?

KYC delays usually happen due to the following reasons:

Your Aadhaar card is not linked to your mobile number, which prevents OTP verification. This slows down the automated process.

The name on your bank account does not match the name on your Aadhaar or PAN card. Even small spelling differences can cause a mismatch.

The bank account linked to your FirstDex profile is inactive, which makes verification difficult.

Blurry or unclear document uploads during KYC submission.

PAN card not being readable or not properly linked to Aadhaar.

We recommend checking all these details before submitting KYC to avoid delays.

What documents are required to complete KYC?

To complete your KYC on FirstDex, the following documents are mandatory:
Aadhaar card – for identity verification.
PAN card – for tax and compliance verification.
Bank passbook or bank statement – to verify the account holder’s name and active status of the bank account.

Ensure the documents are clear and that the name matches across all three.

How long does KYC usually take?

If your Aadhaar is linked with your mobile number, KYC is typically completed within 2 minutes through OTP verification.

In some cases where manual review is needed, it may take up to 24 hours.

Delays can occur if there is a mismatch in name, inactive bank accounts, or unclear documents.

How will I know if my KYC is approved or rejected?

You’ll be notified via:

Email on your registered email ID.
In-app notification or your FirstDex account dashboard.

Rejection messages will always include the specific reason.

What should I do if my KYC is rejected?

If your KYC is rejected:

Check the rejection reason mentioned in the notification.
Make necessary corrections (like uploading clearer images or updating mismatched names).
Re-submit your KYC through the same flow on the FirstDex platform.

If you’re unsure about the issue, you can always contact our support team(support@mg.firstdex.in) for guidance.

Can I change or update my KYC details later?

Yes, you can update your KYC details if:
You’ve changed your bank account.
Your name has changed (e.g., after marriage).
You want to update your address or linked documents.

Please contact support(support@mg.firstdex.in) and provide updated documentation for a smooth update process.

Is KYC mandatory to use FirstDex?

Yes, KYC is mandatory to access the core features of FirstDex.
Without KYC, you won’t be able to:

Make INR deposits or withdrawals.
Swap or cross-chain swap tokens.
Generate tax reports or access certain account features.

We follow regulatory requirements and implement KYC to keep your account and funds safe.

Wallet Safety Measures

How do I keep my wallet safe?

Never Share It: Your seed phrase (or recovery phrase) is the key to your wallet. Sharing it gives full access to your assets.

Store It Securely: Write it down on paper and store it in a safe place, away from digital devices. Avoid taking screenshots or saving it online.

Don’t Enter It Anywhere: Only use your seed phrase on the FirstDex official app.

Biometric Login: Use features like fingerprint or face recognition to open your wallet.

Avoid Phishing Links: Double-check URLs. Scammers often create fake websites to steal wallet details.

Ignore Random Messages: Don’t respond to unsolicited messages offering help or asking for wallet details.

Avoid Public Wi-Fi: Use a VPN if you must access your wallet on an unsecured network.

Small Test Transactions: For large transfers, send a small amount first to ensure the details are correct.

Stay Updated: Follow trusted blockchain resources to learn about new security threats and updates.
