Frequently asked questions
Which chain should we build on?
Depends on cost, finality, ecosystem and compliance. Ethereum L1 for max security and DeFi liquidity, Polygon / Arbitrum / Base for low-cost L2, Solana for high-throughput consumer apps, Hyperledger / Corda for permissioned enterprise use.
Do you handle smart-contract audits?
We prepare contracts for audit (internal review, Slither, Mythril, Foundry fuzzing) and project-manage external audits with firms like Trail of Bits, OpenZeppelin and Halborn. We do not self-certify our own audits.
Can you build the dApp frontend too?
Yes — we ship full-stack Web3. React + wagmi / viem / ethers, WalletConnect, account abstraction (ERC-4337), gasless transactions and fiat on-ramps via Stripe / MoonPay.
Do you support enterprise / permissioned blockchain?
Yes. Hyperledger Fabric, Quorum and R3 Corda for trade finance, supply-chain provenance, KYC-shared ledgers and tokenised settlement.
What happens after mainnet launch?
We provide monitoring (Tenderly, OpenZeppelin Defender), on-call incident response, upgrade governance support and ongoing smart-contract maintenance.
