Disclaimers
What Bloxchain does and does not do with your keys and your data, and where the legal documents live.
Non-custodial
Bloxchain never holds private keys, seed phrases or assets. Every on-chain action is signed by your wallet. Transactions can fail, revert or be irreversible, and Bloxchain cannot reverse them. If you lose a key, Bloxchain cannot recover it; the Recovery role on your account is your fallback.
The SDK runs in your own infrastructure. Key management and RPC security are yours.
Security assurance
The Protocol core is audited by Nethermind (NM_0828), core framework scope. Custom extensions and your own configuration are not covered by that audit. The Bloxchain Platform is Alpha · Testnet · Local-first: it runs on Sepolia today, and Ethereum mainnet is coming soon. An audit does not guarantee the absence of risk, and it does not cover your operational controls or your legal position. Details: Audit status, Known limitations, Security model.
No financial or legal advice
This documentation describes product and Protocol behaviour. It is not investment, legal, tax or compliance advice. Consult qualified professionals for your jurisdiction and use case.
