FAQ
Which blockchains and wallets do you support?
I specialize in Ethereum, Polygon, Binance Smart Chain (BSC), Solana, and Arbitrum. I can integrate popular wallets including MetaMask, WalletConnect, Phantom, Coinbase Wallet, and Trust Wallet
Can you help me accept cryptocurrency payments on my existing website?
Yes. I can integrate crypto payment solutions (like Coinbase Commerce, BitPay, or custom smart contract solutions) into WordPress, Shopify, or custom MERN/React applications to accept ETH, Stablecoins (USDT/USDC), and other tokens.
Do I need to have my own smart contracts for this integration?
No, I can develop custom, secure smart contracts for payment, minting, or staking, or integrate your existing contract with a frontend connecting button.
How do you handle network gas fees and transaction security?
I optimize smart contracts to reduce gas usage and implement industry-standard security patterns to protect against common vulnerabilities like reentrancy attacks. I also provide comprehensive testing on testnets before going live.
What is included in the wallet integration?
The integration includes a "Connect Wallet" button, user authentication (signing a message), fetching wallet balances, and executing transactions (sending/receiving tokens or interacting with a dapp).
Will you provide the source code?
Yes, all source code for the frontend, backend, or smart contracts developed will be delivered upon completion of the project.
Can you help with fiat-to-crypto onramps?
Absolutely. I can integrate solutions like MoonPay, Transak, or Stripe to allow users to purchase crypto directly on your site using credit cards or bank transfers.
What do you need from me to start?
To begin, I need a clear description of the workflow (e.g., "User clicks buy -> MetaMask opens -> User signs txn"), the target blockchain, and your UI design (if applicable)
Do you offer post-delivery support?
Yes, I provide support for 7–30 days (depending on the package) to ensure everything runs smoothly. I also offer bug fixes if any issues arise from my code.
