# Smart Contract-Synced Groups & Auto-Onboarding via Wallet Activity

Sudo introduces smart contract-synced groups and channels, a breakthrough feature that allows Web3 projects to automatically build and manage token-gated communities without relying on manual onboarding or centralized invite systems. By linking groups to verified smart contracts, Sudo enables real-time, on-chain driven access control for DAOs, DApps, DeFi platforms, NFT collections, and beyond.

#### 1. Smart Contract Attachments

Group or channel owners can attach a verified smart contract address directly to their Sudo community. Once linked, the group automatically syncs with all wallet addresses that have interacted with that contract.

Example Use Cases:

* DEXs: Link liquidity pool contracts to create exclusive trader communities.
* NFT Projects: Link minting contracts to auto-onboard verified holders.
* DAOs: Link governance contracts to connect only active voters and proposal creators.<br>

#### 2. Contract Verification Flow

To ensure authenticity, Sudo verifies the contract link through a secure ownership process:

1. Owner Wallet Connection: Group/channel creator connects their Web3 wallet.
2. Ownership Validation: Sudo verifies ownership via methods such as contract.owner(), multisig verification, deployer address check, or signed message.
3. Interaction Mapping: The system retrieves the contract’s on-chain interaction history.
4. Sync Initiation: Auto-onboarding is triggered for eligible wallets.<br>

#### 3. Sync Process – Auto-Onboarding

Once a contract is linked, Sudo automatically builds the group or channel membership list based on on-chain activity:

* Data Retrieval: Fetch all unique wallet addresses that have interacted with the contract (transactions, mints, governance votes, staking events, etc.).
* Eligibility Filtering: Only wallets registered on Sudo are considered for onboarding.
* Instant Access: Eligible wallets are automatically added to the group/channel — no invite link required.
* Real-Time Updates: New wallet interactions with the contract trigger instant auto-adds.\ <br>

#### 4. Key Features

| **Feature**              | **Functionality**                                                           |
| ------------------------ | --------------------------------------------------------------------------- |
| Auto-Onboarding          | Grants group access based solely on verified on-chain activity.             |
| Contract Re-Verification | Owners can replace or update the linked contract at any time.               |
| Wallet Resync Interval   | Membership list updates every hour by default; intervals can be customized. |
| Privacy Preservation     | Wallets not registered with Sudo are ignored to prevent unsolicited access. |

#### 5. Sync at Scale

The system is designed to handle high-volume wallet synchronization efficiently:

* Supports syncing 100,000+ wallets per contract.
* Uses batch processing with Redis queue management and database indexing for speed.
* Compatible with BSC, Ethereum, Polygon, and Solana through a unified indexing system.<br>

#### 6. Monetization Model

Smart contract linking generates direct deflationary pressure on the SUDO token:

* Cost: $10 per contract per year.
* Usage: 100% of fees are converted to SUDO and burned.<br>

Example Impact:

* If 10,000 projects link their smart contracts:
* Revenue = $100,000 USDT.\
  All converted to SUDO and burned annually, reducing circulating supply.<br>

#### 7. Strategic Impact

Smart contract-synced groups reshape community building in Web3:

* Frictionless Onboarding: Wallet activity becomes the access key — no manual invites.
* Stronger Engagement: Members are inherently connected to the project through real transactions.
* Developer Incentives: Projects integrate Sudo for seamless community management.
* Token Utility Growth: Every contract link drives SUDO demand and permanent supply reduction.
