FAQ
Which blockchains do you support?
I support all EVM-compatible and non-EVM blockchains including Solana, Ethereum, BSC, Polygon, Arbitrum, Optimism, Avalanche, Base, custom testnets, and other custom chains with RPC access.
Can you integrate an already deployed smart contract?
Yes. I can integrate existing deployed contracts into your frontend or backend, including read/write functions, events, and transaction handling.
Which wallets can you integrate?
I can integrate MetaMask, WalletConnect, RainbowKit, and multi-wallet setups for both desktop and mobile users.
Is my private key or wallet data safe?
Yes. I never ask for your private keys or seed phrase. Integration only uses public wallet connection methods (MetaMask, WalletConnect, etc.) that you approve yourself.
What if I don't have a smart contract deployed yet?
No problem. I can write and deploy the smart contract for you first, then integrate the wallet connection on top of it — just message me your project details.
