📈 Autonomous Trading

Overview

Eliza's autonomous trading system enables automated token trading on the Solana blockchain. The system integrates with Jupiter aggregator for efficient swaps, implements smart order routing, and includes risk management features.

Core Components

Token Provider

Manages token information and market data:

class TokenProvider {
  constructor(
    private tokenAddress: string,
    private walletProvider: WalletProvider,
  ) {
    this.cache = new NodeCache({ stdTTL: 300 }); // 5 minutes cache
  }

  async fetchPrices(): Promise<Prices> {
    const { SOL, BTC, ETH } = TOKEN_ADDRESSES;
    // Fetch current prices
    return {
      solana: { usd: "0" },
      bitcoin: { usd: "0" },
      ethereum: { usd: "0" },
    };
  }

  async getProcessedTokenData(): Promise<ProcessedTokenData> {
    return {
      security: await this.fetchTokenSecurity(),
      tradeData: await this.fetchTokenTradeData(),
      holderDistributionTrend: await this.analyzeHolderDistribution(),
      highValueHolders: await this.filterHighValueHolders(),
      recentTrades: await this.checkRecentTrades(),
      dexScreenerData: await this.fetchDexScreenerData(),
    };
  }
}

Swap Execution

Implementation of token swaps using Jupiter:

async function swapToken(
  connection: Connection,
  walletPublicKey: PublicKey,
  inputTokenCA: string,
  outputTokenCA: string,
  amount: number,
): Promise<any> {
  // Get token decimals
  const decimals = await getTokenDecimals(connection, inputTokenCA);
  const adjustedAmount = amount * 10 ** decimals;

  // Fetch quote
  const quoteResponse = await fetch(
    `https://quote-api.jup.ag/v6/quote?inputMint=${inputTokenCA}` +
      `&outputMint=${outputTokenCA}` +
      `&amount=${adjustedAmount}` +
      `&slippageBps=50`,
  );

  // Execute swap
  const swapResponse = await fetch("https://quote-api.jup.ag/v6/swap", {
    method: "POST",
    body: JSON.stringify({
      quoteResponse: await quoteResponse.json(),
      userPublicKey: walletPublicKey.toString(),
      wrapAndUnwrapSol: true,
    }),
  });

  return swapResponse.json();
}

Position Management

Order Book System

interface Order {
  userId: string;
  ticker: string;
  contractAddress: string;
  timestamp: string;
  buyAmount: number;
  price: number;
}

class OrderBookProvider {
  async addOrder(order: Order): Promise<void> {
    let orderBook = await this.readOrderBook();
    orderBook.push(order);
    await this.writeOrderBook(orderBook);
  }

  async calculateProfitLoss(userId: string): Promise<number> {
    const orders = await this.getUserOrders(userId);
    return orders.reduce((total, order) => {
      const currentPrice = this.getCurrentPrice(order.ticker);
      const pl = (currentPrice - order.price) * order.buyAmount;
      return total + pl;
    }, 0);
  }
}

Position Sizing

async function calculatePositionSize(
  tokenData: ProcessedTokenData,
  riskLevel: "LOW" | "MEDIUM" | "HIGH",
): Promise<CalculatedBuyAmounts> {
  const { liquidity, marketCap } = tokenData.dexScreenerData.pairs[0];

  // Impact percentages based on liquidity
  const impactPercentages = {
    LOW: 0.01, // 1% of liquidity
    MEDIUM: 0.05, // 5% of liquidity
    HIGH: 0.1, // 10% of liquidity
  };

  return {
    none: 0,
    low: liquidity.usd * impactPercentages.LOW,
    medium: liquidity.usd * impactPercentages.MEDIUM,
    high: liquidity.usd * impactPercentages.HIGH,
  };
}

Risk Management

Token Validation

async function validateToken(token: TokenPerformance): Promise<boolean> {
  const security = await fetchTokenSecurity(token.tokenAddress);

  // Red flags check
  if (
    security.rugPull ||
    security.isScam ||
    token.rapidDump ||
    token.suspiciousVolume ||
    token.liquidity.usd < 1000 || // Minimum $1000 liquidity
    token.marketCap < 100000 // Minimum $100k market cap
  ) {
    return false;
  }

  // Holder distribution check
  const holderData = await fetchHolderList(token.tokenAddress);
  const topHolderPercent = calculateTopHolderPercentage(holderData);
  if (topHolderPercent > 0.5) {
    // >50% held by top holders
    return false;
  }

  return true;
}

Trade Management

interface TradeManager {
    async executeTrade(params: {
        inputToken: string,
        outputToken: string,
        amount: number,
        slippage: number
    }): Promise<string>;

    async monitorPosition(params: {
        tokenAddress: string,
        entryPrice: number,
        stopLoss: number,
        takeProfit: number
    }): Promise<void>;

    async closePosition(params: {
        tokenAddress: string,
        amount: number
    }): Promise<string>;
}

Market Analysis

  return {
    price: await fetchCurrentPrice(tokenAddress),
    volume_24h: await fetch24HourVolume(tokenAddress),
    price_change_24h: await fetch24HourPriceChange(tokenAddress),
    liquidity: await fetchLiquidity(tokenAddress),
    holder_data: await fetchHolderData(tokenAddress),
    trade_history: await fetchTradeHistory(tokenAddress),
  };
}

  runtime: IAgentRuntime,
  input: {
    tokenIn: string;
    tokenOut: string;
    amountIn: number;
    slippage: number;
  },
): Promise<string> {
  // Prepare transaction
  const { swapTransaction } = await getSwapTransaction(input);

  // Sign transaction
  const keypair = getKeypairFromPrivateKey(
    runtime.getSetting("SOLANA_PRIVATE_KEY") ??
      runtime.getSetting("WALLET_PRIVATE_KEY"),
  );
  transaction.sign([keypair]);

  // Execute swap
  const signature = await connection.sendTransaction(transaction);

  // Confirm transaction
  await connection.confirmTransaction({
    signature,
    blockhash: latestBlockhash.blockhash,
    lastValidBlockHeight: latestBlockhash.lastValidBlockHeight,
  });

  return signature;
}

  runtime: IAgentRuntime,
  params: {
    inputToken: string;
    outputToken: string;
    amount: number;
  },
): Promise<string> {
  const authority = getAuthorityKeypair(runtime);
  const [statePDA, walletPDA] = await derivePDAs(authority);

  // Prepare instruction data
  const instructionData = prepareSwapInstruction(params);

  // Execute swap through DAO
  return invokeSwapDao(
    connection,
    authority,
    statePDA,
    walletPDA,
    instructionData,
  );
}

  return {
    connection: await checkConnectionStatus(),
    wallet: await checkWalletBalance(),
    orders: await checkOpenOrders(),
    positions: await checkPositions(),
  };
}

Safety Limits

const SAFETY_LIMITS = {
  MAX_POSITION_SIZE: 0.1, // 10% of portfolio
  MAX_SLIPPAGE: 0.05, // 5% slippage
  MIN_LIQUIDITY: 1000, // $1000 minimum liquidity
  MAX_PRICE_IMPACT: 0.03, // 3% price impact

    await handleInsufficientFunds();
  } else if (error.message.includes("slippage tolerance exceeded")) {
    await handleSlippageError(transaction);
  } else {
    await logTransactionError(error, transaction);
  }
}

Recovery Procedures

async function recoverFromError(
  error: Error,
  context: TradingContext,
