FAQ
Which blockchains do you support?
We build on Ethereum, BSC, Polygon, Base, Bitcoin, Solana and Tron. We also support custom EVM chains and testnets. Tell us your target chains before ordering and we will confirm feasibility and timeline.
Is the wallet non custodial? Who controls the private keys?
Non custodial by default. Private keys are generated on the user device and never touch a server. Users hold their own seed phrase. If you need a custodial or MPC architecture instead, message us first as that changes scope and cost.
Do you handle App Store and Play Store submission?
We prepare builds, store assets and submission materials, and guide you through the process. The developer accounts must be registered in your company name, so final submission is made from your accounts.
Can you help me recover lost crypto or a forgotten seed phrase?
No. We are a development agency and we build wallet software. We cannot recover lost funds, forgotten seed phrases or compromised accounts, and nobody legitimately can. Anyone claiming otherwise is running a scam.
What about security audits?
We build with audit readiness in mind: encrypted key storage, secure enclave and keystore use, and no key material transmitted off device. Formal third party audit is a separate engagement we can coordinate on request.
How long does a wallet actually take to build?
A single chain web wallet takes around two weeks. Multi chain with iOS and Android takes four to six weeks. A full platform with swap, staking and white label typically runs eight weeks or more. We confirm a firm timeline before you order.
