# Security ### Proven Codebase Zeltra is built on **go-ethereum**, the reference implementation of the Ethereum protocol. This client has been developed in open source for years, audited by hundreds of security researchers, and used to secure tens of billions of dollars in value on the Ethereum mainnet. By adopting this foundation, Zeltra directly benefits from all security patches integrated into go-ethereum — including fixes applied to CVE vulnerabilities identified in earlier versions of the client, notably several critical flaws in the P2P network layer. ### ChainId Isolation **ChainId 271017** uniquely identifies the Zeltra network. This mechanism, introduced by EIP-155 on Ethereum, ensures that any transaction signed for the Zeltra network cannot be replayed on another EVM network, and vice versa. This is a fundamental protection against cross-chain replay attacks. ### PoA Trust Model During the Proof of Authority phase, security relies on the known and verifiable identity of validators. This model significantly reduces the attack surface during the bootstrapping phase: there is no open competition that could be exploited by malicious actors on a network that is still young. ### Audits Security audits of the protocol and the multisig fund smart contracts will be conducted before critical milestones notably before the launch of the partnership program and before the migration to PoS. ### Responsible Disclosure A responsible disclosure process will be established, allowing security researchers to report vulnerabilities in a coordinated and confidential manner, before any public disclosure. {% hint style="danger" %} No blockchain network is invulnerable. Users are encouraged to conduct their own risk assessment before interacting with the network. {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://zeltra.gitbook.io/zeltra-docs/basics/security.md?ask= ``` The question should be specific, self-contained, and written in natural language.
