Solana Plugin V2 for Eliza 🌟

The Solana Plugin V2 leverages the latest features of @solana/web3.js v2 to provide a modern, efficient, and composable solution for Solana integrations within the Eliza AI agent framework.

---

Key Features 🚀

Modern JavaScript and Functional Architecture

• @solana/web3.js v2 introduces:
  • Tree-shakability
  • Composable internals
  • Zero-dependency design
  • Functional programming approach

Compatibility with existing solana V1 plugins

• This plugin can be used by the agent alongside existing plugins that use @solana/web3.js v1.

Common Utilities

The Utils class provides shared functionality across the plugin, offering flexibility and ease of integration.

sendTransaction

• Accepts the RPC instance, transaction instructions, and a wallet.
• Utilizes Solana's Compute Budget Program for optimized CU usage and priority fees.
• Implements client-side retry logic to enhance transaction landing success.
• More details on optimizing transactions can be found here.

Trusted Execution Environment (TEE)

• For Trusted Execution Environment (TEE) functionality, this plugin transitions from Keypair (used in v1) to CryptoKeyPair from the Web Crypto API. This change aligns with @solana/web3.js v2's zero-dependency, modern JavaScript architecture.
• A modified implementation for TEE integration is included in src/utils/, following the same patterns used in plugin-tee.

Current Functionality 🎯

Liquidity Position Management

• Reposition Liquidity:
  • Automatically repositions Orca liquidity positions if the center price of the position deviates from the current pool price by more than a user-specified threshold (repositionThresholdBps).
  • Maintains the original width of the position during repositioning.
  • Repositions at a user defined time interval.
  • Uses a slippage tolerance set by the user.

How to run the Orca LP Management tool

1. Set up your environment variables

• In the root of the repositorty, copy .env.example to .env
• Fill in the following parameters:
  • SOLANA_PRIVATE_KEY
  • SOLANA_PUBLIC_KEY
  • SOLANA_RPC_URL
  • OPENAI_API_KEY

2. RPC requirements

Most often, free-tier RPC URLs are not sufficient for this plugin.

• Eliza needs to fetch all your token-accounts in order to find the position NFTs that represent Orca positions. Such calls are done through the getProgramAccounts method of the RPC client, which can be expensive.
• To ensure transaction landing, the plugin makes use of a client-side retry logic (read more here), which also puts a heavier load on the RPC.
• The amount of positions you own and the update interval you set can also contribute to RPC limits.

3. Update the agent

In agent/src/index.ts, search for the function createAgent, and add solana_plugin_v2 to the AgentRuntime like so:

export async function createAgent(
    character: Character,
    db: IDatabaseAdapter,
    cache: ICacheManager,
    token: string
): Promise<AgentRuntime> {
    // Rest of the code ...

    return new AgentRuntime({
        // Other parameters
        plugins: [
            // Other plutins
            getSecret(character, "SOLANA_PUBLIC_KEY") ||
            (getSecret(character, "WALLET_PUBLIC_KEY") &&
                !getSecret(character, "WALLET_PUBLIC_KEY")?.startsWith("0x"))
                ? solanaPluginV2
                : null,
    // Rest of the code

4. Use LP Manager character

Copy packages/plugin-solana-v2/src/character/orca/lpmanager.character.json to characters/lpmanager.character.json.

5. Install and build the repo

Follow the general installation and build steps from the README in the root of the repo

5. Run the agent

Start the the agent with the following command:

pnpm start --characters="characters/lpmanager.character.json"

Start the client (chat terminal) with:

pnpm start:client

6. Start prompting

Ask the agent what it can do for you. Provide the appropriate parameters and let the agent reposition your positions automatically.

7. Other configurations

In packages/plugin-solana-v2/src/utils/sendTransaction.ts, you can set the priority fees. They are by default set to use the dynamic fees, but you can adjust this as you like.

Future Functionality 🔮

Position Management Enhancements

• Opening and Closing Positions:
  • Expose opening and closing positions as separate actions.
  • Allow agents to leverage data streams and other plugins for decision-making and yield optimization.

Token Launches

• Token Creation and Liquidity Setup:
  • Create tokens with metadata using the Token 2022 Program.
  • Launch tokens on Orca with single-sided liquidity.
  • Configure start and maximum prices for initial liquidity.
