🏦Emblem SDK

The Emblem Vault SDK isn't just another wallet integration, this is the infrastructure that's reshaping how agents and humans collaborate across chains.

🏗️ Core Architecture

The Vault System

• Emblem Vaults are smart contract-based containers that hold multiple assets across different blockchains

• Each vault has a unique NFT representation—making complex multi-chain portfolios tradeable as single units

• The SDK abstracts vault creation, management, and interaction into clean JavaScript/TypeScript APIs

Cross-Chain Abstraction Layer

• Unified interface for 15+ blockchains without developers needing to understand each chain's specifics

• Automatic gas estimation, transaction routing, and confirmation handling

• Built-in retry logic and error handling for network instabilities

⚙️ SDK Components Breakdown

1. Vault Management Module

• Create, configure, and manage vaults programmatically

• Set permissions, beneficiaries, and access controls

• Batch operations across multiple vaults

2. Asset Integration Engine

• Token Support: ERC-20, SPL, BEP-20, native coins, and more

• NFT Handling: Cross-chain NFT deposits, withdrawals, and metadata management

• DeFi Positions: LP tokens, staking positions, yield farming rewards

• Real-time Valuation: Integrated pricing feeds for accurate portfolio tracking

3. Transaction Orchestration

• Multi-signature Support: Enterprise-grade security with customizable signing requirements

• Atomic Operations: Either all transactions succeed or all fail—no partial states

• Gas Optimization: Intelligent batching and timing to minimize costs

• Cross-chain Bridges: Automated asset movement between supported networks

4. AI Agent Integration Layer

• Programmatic Access: Agents can create and manage vaults without human intervention

• Strategy Execution: Deploy complex multi-chain strategies automatically

• Collaboration Framework: Multiple agents can share vault access with defined permissions

• Event Webhooks: Real-time notifications for portfolio changes, threshold breaches, etc.

🌐 Supported Networks & Protocols

Layer 1s: Ethereum, Bitcoin, Solana, Binance Smart Chain, Polygon, Avalanche, Fantom Layer 2s: Arbitrum, Optimism, Base, zkSync Specialized: Hedera Hashgraph, Cardano, Polkadot Emerging: Sui, Aptos, and more being added regularly

Each network integration includes:

• Native asset support

• Major DEX integrations (Uniswap, PancakeSwap, Jupiter, etc.)

• DeFi protocol connections

• NFT marketplace access

🤖 Why This Matters for AI Agents

Before Emblem SDK: Agents needed separate integrations for each chain, complex key management, and couldn't easily collaborate or share strategies.

With Emblem SDK:

• Single Integration: One SDK call works across all supported chains

• Shared Intelligence: Agents can create vaults that other agents can access and build upon

• Persistent Strategies: Vaults maintain state and execute strategies even when agents are offline

• Risk Management: Built-in safeguards and permissions prevent unauthorized actions

🚀 Real-World Applications

For Developers:

• Build cross-chain DeFi apps without blockchain expertise

• Create portfolio management tools with enterprise features

• Integrate multi-chain functionality in days, not months

For AI Agents:

• Execute sophisticated trading strategies across multiple chains

• Collaborate on shared investment pools

• Manage user portfolios with full transparency and security

For Users:

• Single interface for all digital assets

• Simplified DeFi participation

• Tradeable portfolio positions as NFTs
