Traditional SSH vs Nexion

Say goodbye to traditional SSH management pain points

Traditional Way
Identity & Credentials
Multiple key sets, hard to share and revoke, error-prone.
Configuration & Sync
Manual backup/sync, cross-device chaos.
Security & Audit
Plain/semi-plain text storage, lack of audit and accountability.
Collaboration & Permissions
Coarse permission granularity, complex team management.
Total Cost of Ownership
High maintenance labor, unpredictable compliance and incident costs.
Nexion Way
Unified Wallet Auth
Web3 wallet as identity, one-click authorization/revocation.
On-Chain Encrypted Storage
ECIES encryption, configs on-chain, accessible everywhere.
Traceable Audit
On-chain events queryable, operation traces verifiable.
Contract-based Permissions
Smart contracts manage team permissions, principle of least privilege.
Low Cost High Return
X Layer low gas, automation reduces operational costs.
