Security Paradigms

OmniSocial is designed from the ground up to resist both traditional and emerging digital threats.

From zero-knowledge security primitives to multi-factor authentication and smart contract upgrade governance, the platform's architecture prioritizes user sovereignty and platform resilience.

🧠 ZK Security Foundation: zkEVM + zkSNARKs

OmniSocial is deployed on Polygon zkEVM, inheriting its Ethereum-equivalent security with zero-knowledge verification guarantees.

Benefits:

• Validity proofs (zkSNARKs) verify all L2 transactions on L1

• Finality guarantees after batch validity is posted

• Reduced attack surface for replay or fraud attempts

zkEVM preserves the same developer tooling and signature logic as Ethereum while enabling succinct, privacy-preserving verification.

🔑 OmniWallet + Two-Factor Authentication

Every user account is powered by an OmniWallet—a smart contract wallet with modular security features.

🔐 Two-Factor Authentication (2FA)

OmniWallet supports optional WebAuthn-based 2FA for sensitive actions.

🔄 Technical Flow (WebAuthn):

1. User links a hardware key or biometric authenticator (via browser WebAuthn).

2. Challenge is generated server-side (or locally).

3. Authenticator signs challenge.

4. Signature is submitted with contract interaction.

5. Smart contract validates the WebAuthn signature before executing.

2FA Protected Actions:

• Voting on high-value proposals

• Executing DAO upgrades

• Sending large transfers

• Recovery actions

🛟 Account Recovery: Guardian + SBT Mechanism

If a user loses access to their device or wallet, OmniSocial enables multi-path recovery using social guardians and Soulbound Tokens (SBTs).

🔧 Recovery Setup:

• Link 1–3 trusted contacts (guardian addresses)

• Mint a non-transferable RecoverySBT to their wallets

• If recovery is needed, a threshold of guardians signs off on the new key

Contract Events:

• RecoveryInitiated(user, newOwner)

• GuardianSigned(guardian, user)

• OwnershipTransferred(user, newOwner)

Recovery is only permitted if the correct guardian quorum is reached within a time window.

🧬 Upgradeability & Governance

All core contracts (OmniWallet, PersonaNFT, DAO, RepModule) follow UUPS proxy upgrade patterns.

How upgrades work:

• Each proxy points to an implementation contract

• Upgrades are proposed via governance

• After quorum is met, the proxy is pointed to a new implementation

Contract Functions:

function upgradeTo(address newImplementation) external onlyAdmin;
function authorizeUpgrade(address newImplementation) internal override onlyDAO;

Only the DAO or authorized multisig can perform upgrades—users are protected against rug-pulls and unauthorized logic changes.

🛡 Threat Matrix & Mitigations

Threat	Mitigation
Wallet compromise	Smart wallet with optional 2FA, multisig recovery via guardians
Lost keys	Social recovery with SBTs + guardians
Sybil attacks	zk-based Proof of Humanity & pseudonym separation via personas
Replay or invalid tx on L2	zkEVM with zkSNARK finality enforcement
DAO proposal hijack	Reputation-weighted voting + quorum + 2FA enforcement on execution
Smart contract vulnerabilities	UUPS upgradability + audits + gradual feature rollout
Censorship or centralized moderation	DAO-based community governance & moderation tooling
