Use NFT Avatars

Web3 identity inside Telegram chats through verifiable digital ownership. BlockGram enables users to set, display, and interact with NFT-based avatars directly within the Telegram interface. These avatars go beyond traditional profile images by embedding ownership, interactivity, and metadata on-chain, allowing users to bring their Web3 identity into everyday conversations.

1. Overview: What Are NFT Avatars in BlockGram?

NFT avatars in BlockGram are tokenized digital identity representations stored on supported blockchains. Unlike static images, NFT avatars are:

• Verifiably owned through blockchain token standards (ERC-721 or ERC-1155)

• Capable of embedding metadata, animation, and interactivity

• Used as visual identity, status symbols, or access tokens across different use cases

Users can configure NFT avatars to replace or augment their Telegram profile pictures. Display is opt-in and visible to participants in chats and groups that support the feature.

2. Avatar NFT Integration Pipeline

Layer	Function
Ownership Verification	BlockGram scans connected wallets for eligible NFTs via on-chain indexing protocols such as The Graph
Media Rendering	Supports formats including PNG, GIF, SVG, and 3D (GLTF). NFT metadata is resolved through IPFS, Arweave, or contract-hosted URIs
Identity Binding	Users link their Telegram ID to a wallet address using EIP-4361 signature or a zk-based identity proof
Real-Time Synchronization	Changes in NFT ownership or metadata are reflected in real time using caching, polling, or bot-based updates

3. Standards and Compatibility

Supported Blockchains:

• Ethereum Mainnet

• Polygon

• Arbitrum

• BNB Smart Chain

• Solana (via bridge and metadata wrapper)

Supported Token Standards:

• ERC-721

• ERC-1155

• Custom metadata formats with animation_url, external_url, and attributes fields

Avatar Collections:

• Official collections are curated and verified by the BlockGram team

• Community collections can be proposed and approved through token governance mechanisms

4. Technical Architecture

Avatar Rendering Flow:

1. User connects a wallet via the BlockGram interface

2. NFTs are queried using a subgraph or direct RPC call

3. Metadata is fetched and decoded from the tokenURI field

4. Media is rendered either client-side or via a CDN-based preview renderer

5. The Telegram profile is updated using inline bot overlay features or custom extensions

Rendering Modes:

• Static image overlay for profile thumbnails

• Animated previews (GIF, WebM) displayed in chat windows

• Planned support for embedded 3D or interactive avatars using Telegram WebView components

5. Use Cases and Identity Layer Integration

BlockGram leverages NFT avatars to enable programmable identity and access features:

Use Case	Implementation Details
DAO-Restricted Chats	Only wallets holding specified NFTs can join certain Telegram groups
Status Tiers and Flair	Avatar frames or effects change based on rarity or staking level
Event Credentials and POAPs	Special NFTs act as passes for group access or event verification
Group Identity Badges	Members of NFT-based communities can wear group-specific avatars or badges

Users can manage multiple NFT avatars and switch between them using an avatar selector in the BlockGram wallet interface.

6. Security and Privacy Considerations

• Displaying NFT avatars is fully optional and user-controlled

• No public wallet address is shared unless explicitly authorized by the user

• Media is served through access-controlled endpoints or local caching

• Users may disable or revert to the default Telegram profile at any time

7. Key Benefits

• Connects Web3 identity to everyday messaging

• Enables visual self-expression backed by verifiable ownership

• Supports social signaling, gated access, and NFT-powered community interactions

• Enhances Telegram’s static identity layer with dynamic, on-chain personalization
