DNSSEC + Registry Lock
Signing DNS zones with DNSSEC and enabling registry lock on sensitive TLDs ensures that any unauthorized name-server or registrar change is rejected at the registry layer.
Why Registrars Matter
Protecting DeFi Domains
Registrars guard the root of your DNS supply chain. A compromised registrar account can redirect your entire protocol, so mature security programs treat domain custody like wallet custody. This type of attack is so common that Seal911 has an advisory on it. Some suggested DNS registrars are Cloudflare, AWS, MarkMonitor, and CSCDBS
Security approaches
These practices illustrate how different teams mitigate registrar-level takeover risk.
Role-Based Registrar Accounts
Segment registrar credentials by role, require hardware-backed MFA, and limit access so only specific teams can approve contact or name-server updates.
Multi-Signer Change Controls
Apply multi-party approvals for registrar modifications—similar to multisig wallets—so that a single compromised engineer cannot hijack a domain.
24/7 Monitoring & Escrow
Subscribe to registrar alerts, monitor for WHOIS drift, and keep pre-arranged recovery channels (escrowed auth codes, registry contacts) to rapidly claw back a name.
