5. Implementation
Quick Setup
Install Dependencies
Install LangChain and required LLM providers.
npm install langchain openai
Configure API Keys
Set up API keys for LLM providers and blockchain access.
Initialize Integration
Create your first LangChain application with blockchain integration.
Code Example
// LangChain Integration Example
import { ChatOpenAI } from "langchain/chat_models/openai"
import { ConversationChain } from "langchain/chains"
import { BufferMemory } from "langchain/memory"
// Initialize LLM with blockchain context
const llm = new ChatOpenAI({
modelName: "gpt-4",
temperature: 0.7,
maxTokens: 1000
})
// Setup conversation memory
const memory = new BufferMemory({
returnMessages: true,
memoryKey: "chat_history"
})
// Create blockchain-aware conversation chain
const chain = new ConversationChain({
llm: llm,
memory: memory,
verbose: true
})
// Smart contract analysis function
async function analyzeContract(contractCode: string) {
const prompt = `
Analyze this smart contract and provide:
1. Security assessment
2. Gas optimization suggestions
3. Code quality review
Contract: ${contractCode}
`
const response = await chain.call({
input: prompt
})
return response.response
}
// Trading assistant function
async function tradingAssistant(query: string) {
const response = await chain.call({
input: `As a blockchain trading assistant: ${query}`
})
return response.response
}
7. Best Practices
Performance Optimization
- • Use streaming responses for long operations
- • Implement proper caching strategies
- • Optimize prompt engineering
- • Monitor token usage and costs
Security Considerations
- • Validate all user inputs
- • Implement rate limiting
- • Secure API key management
- • Monitor for prompt injection attacks
