FAQ
What is the difference between EVM, Cosmos SDK, and Polkadot?
EVM chains are Ethereum-compatible (MetaMask works out of the box). Cosmos SDK gives you sovereign chains with IBC interoperability. Polkadot parachains share security from the Polkadot relay chain. I'll recommend the best fit for your project.
Can I have privacy features on my blockchain?
Yes! I implement zero-knowledge proofs (zk-SNARKs/zk-STARKs), confidential transactions, and private smart contract execution for maximum privacy — ideal for enterprise or financial blockchain use cases.
Will I get the full source code?
Absolutely. You receive 100% of the source code, full documentation, deployment scripts, and a walkthrough session to ensure you can manage and upgrade your chain independently.
