Access Control

Sigma Auth's Access Control system allows you to gate features and content based on what users hold on the blockchain. This enables powerful use cases like NFT memberships, tiered rewards programs, and token-based subscriptions.

Overview

Access Control provides two types of verification:

NFT Ownership Verification

Check if a user owns specific NFTs or ordinals:

• Membership NFTs for exclusive content
• Monthly/annual subscription tokens
• On-chain certificates and credentials
• 1Sat Ordinals on BSV blockchain

Token Threshold Verification

Create tiered access based on token holdings:

• Gold/Diamond/Platinum VIP levels
• Governance voting weight
• Loyalty and rewards programs
• Staking requirements

How It Works

1. User Authentication: Users authenticate with their Bitcoin identity (BAP)
2. Wallet Registration: Users register additional wallet addresses for verification
3. On-Chain Verification: Your app requests verification from Sigma Auth
4. Cryptographic Proof: Sigma Auth verifies ownership on-chain
5. Access Granted: Your app receives confirmation and grants access

Use Cases

NFT Membership Sites

Gate premium content behind NFT ownership. Mint monthly access passes as ordinals on BSV.

Example: A premium course platform that requires ownership of a specific NFT collection.

Tiered Rewards Programs

Create Gold/Platinum/Diamond tiers based on token holdings. Automatically adjust perks as balances change.

Example: A DeFi platform with increasing APY rates based on governance token holdings.

DAO & Governance

Weight voting power by token holdings. Verify proposal access with governance NFTs.

Example: A DAO that requires minimum token holdings to submit proposals.

Token-Based Subscriptions

Sell monthly/annual subscriptions as NFTs. Users pre-pay by purchasing the current period's token.

Example: A SaaS app that issues monthly NFTs as subscription tokens.
