What's inside Chainstack

  1. Overview of the AI Trading Agent Development Pipeline

    The AI trading agent pipeline is a multi-stage evolution designed to move from manual blockchain interactions to a fully autonomous, AI-driven trading system. The development path progresses through the following levels:

    1. Manual Swap: Basic understanding of Uniswap V4 mechanics via MetaMask.
    2. Bot Script Automation: Programmatic execution of one-off ETH-USDC swaps using predefined rules.
    3. Stateless AI Agent: Integration of local LLMs (via Ollama) to make trading decisions based on real-time data without memory of previous trades.
    4. Stateful AI Agent: Addition of persistent memory, trading history, and performance tracking to manage context and strategy effectiveness.
    5. Data Collection: Extraction of historical swap events from the Base mainnet to prepare for model training.
    6. Synthetic Data Generation: Using Generative Adversarial Networks (GANs) and WGAN-GP to create realistic training datasets for time-series market data.
    7. Model Distillation: Using a teacher-student architecture (e.g., QwQ 32B teacher to Qwen 2.5 3B student) with LoRA adaptation and 'Chain of Draft' prompting.
    8. Reinforcement Learning (RL): Optimizing strategies using a custom Gymnasium environment and Deep Q-Networks (DQN) with experience replay.
    9. Final Autonomous Agent: A complete system combining fine-tuned models, real-time data, risk management, and performance monitoring.

  2. Overview of TRON API surfaces and endpoints

    Chainstack provides a single node endpoint that exposes four different API surfaces. To use a specific surface, append the corresponding path to your endpoint URL, except for gRPC which uses a dedicated host on port 443.

    • HTTP /wallet: Full node access for accounts, blocks, contracts, resource staking, and transaction broadcasting.
    • HTTP /walletsolidity: Read-only access to solidified (confirmed) data.
    • Ethereum JSON-RPC (/jsonrpc): Read-only Ethereum-compatible interface. Note: Methods for transaction submission (e.g., eth_sendRawTransaction) are not available; use the /wallet API or TronWeb.js for writes.
    • gRPC: High-performance binary access and indexing using HTTP/2 and Protocol Buffers.

  3. Overview of Custom JS Tracing for Ethereum

    Custom JavaScript tracing allows developers to filter and extract specific data points from the Ethereum Virtual Machine (EVM) during transaction execution. Instead of reviewing the entire transaction trail, users can provide a JavaScript expression to the tracer option of a tracing RPC method to isolate required information.

    Availability: This feature is available only on customized Dedicated Nodes on the Enterprise plan.

  4. Overview of the Stateless AI Trading Agent

    The stateless AI trading agent is designed for independent blockchain market analysis calls without session memory, making it ideal for serverless deployment. It combines local language models (LLMs) with real-time market data to make autonomous trading decisions on Uniswap V4. Because it is stateless, each decision is treated as an independent event with no historical context or bias from previous trades, which simplifies debugging and ensures predictable behavior.

  5. Overview of the Base B20 token standard

    B20 is Base's native, ERC-20-compatible token standard implemented as a native precompile rather than a smart contract. It is a superset of ERC-20, meaning it maintains full selector parity and is a drop-in replacement for wallets, explorers, and indexers, while offering higher throughput and lower costs than standard EVM execution. Key features include built-in roles, transfer policies, supply caps, pausing, memos, and permit functionality.

  6. Overview of Hyperliquid API execution layers

    Hyperliquid is a Layer 1 blockchain with two integrated execution layers sharing a single consensus mechanism (HyperBFT):

    1. HyperCore: A high-performance Rust-based on-chain order book for perpetuals and spot trading. It supports up to 200,000 orders per second with one-block finality and zero gas fees for order matching and margin management.
    2. HyperEVM: An Ethereum-compatible smart contract layer that allows developers to build permissionless applications using Solidity. HyperEVM contracts can read HyperCore state (prices, positions, balances) via precompiles and write to HyperCore via the CoreWriter system contract.

  7. Overview of the pump.fun trading bot

    This Python-based bot monitors the pump.fun on-chain program to detect new tokens, automatically buy them, and optionally sell them based on a configured strategy. It interacts directly with Solana programs and accounts using the Anchor framework and the pump.fun IDL, avoiding third-party APIs. Key technical details include:

    • Program ID: The bot monitors the pump.fun main program ID 6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P.
    • Token Decimals: Tokens created via pump.fun use 6 decimals (unlike the standard Solana 9 decimal SPL tokens).
    • Supported Platforms: Supports both pump.fun and letsbonk.fun via configuration.

  8. Overview of Bun JavaScript runtime capabilities

    Bun is an all-in-one JavaScript toolkit designed for running, building, testing, and debugging JS and TS applications. Key features include:

    • Native Web APIs: Built-in support for fetch, Request, Response, WebSocket, and ReadableStream.
    • TypeScript & JSX: Ability to run .ts, .tsx, and .jsx files directly without external compilers.
    • Module Compatibility: Supports both CommonJS and ES modules without additional configuration.
    • Performance: Optimized standard-library APIs that outperform many node.js counterparts.

  9. Overview of Foundry toolkit components

    Foundry is a modular toolkit for Ethereum smart contract development consisting of four primary components:

    • Forge: The main build and test tool used for compiling contracts and running tests (including fuzz and property-based tests).
    • Anvil: A local Ethereum node used for rapid iteration and debugging in a local blockchain environment.
    • Cast: A CLI tool for interacting with Ethereum, such as sending transactions, querying blockchain data, and converting values.
    • Chisel: A Solidity REPL (Read-Eval-Print Loop) for interactively testing and experimenting with Solidity code snippets.

  10. Overview of Ethereum API on Chainstack

    Chainstack provides a single Ethereum node endpoint that serves both the Execution Layer (via JSON-RPC) and the Consensus Layer (via Beacon Chain REST API). This allows developers to query account state, deploy smart contracts, and track validator finality through one connection. The service supports Mainnet, Sepolia, and Hoodi networks with both full and archive node options.

  11. Overview of Hyperliquid development capabilities

    Hyperliquid is an L1 blockchain featuring an onchain order book. Developers can build applications that leverage the following capabilities:

    • Exchange API Authentication: Using EIP-712 signature generation for secure requests.
    • Trading Automation: Building bots for perpetual and spot markets, including order lifecycle management (place, modify, cancel) and risk management (leverage controls, isolated margin).
    • Asset Management: Transferring USDC and spot tokens between accounts and wallets.
    • Real-time Data: Streaming market data via WebSocket feeds for order books and trades.
    • Smart Contracts: Deploying and interacting with DeFi applications on the HyperEVM.
    • Node Infrastructure: Configuring nodes for system transactions and cross-layer transfers.

  12. Overview of TON Blockchain API Methods

    Chainstack provides a comprehensive set of v2 and v3 API endpoints for interacting with the TON blockchain. These methods cover address information, transaction history, block data, NFTs, Jettons, and smart contract interactions.

    Pricing Model:

    • Full requests: 1 Request Unit (RU)
