Extend the agent with custom actions:
import { Action, Tool, SolanaAgentKit } from "solana-agent-kit";
// Define the Tool (tells LLM HOW to use it)
const myCustomTool: Tool = {
name: "my_custom_action",
description: "Does something custom on Solana",
parameters: {
type: "object",
properties: {
param1: {
type: "string",
description: "First parameter",
},
param2: {
type: "number",
description: "Second parameter",
},
},
required: ["param1"],
},
};
// Define the Action (tells agent WHEN and WHY to use it)
const myCustomAction: Action = {
name: "my_custom_action",
description: "Use this when you need to do something custom",
similes: ["custom thing", "special operation"],
examples: [
{
input: "Do the custom thing with value X",
output: "Custom action executed with param1=X",
},
],
handler: async (agent: SolanaAgentKit, params: any) => {
const { param1, param2 } = params;
// Your custom logic here
const connection = agent.connection;
const wallet = agent.wallet;
// Execute Solana operations...
return {
success: true,
result: `Executed with ${param1}`,
};
},
};
// Register custom action
agent.registerAction(myCustomAction);
agent.registerTool(myCustomTool);

Version 2 represents a complete evolution of the toolkit with key improvements:
V2 directly addresses two major V1 challenges:
The modular plugin system lets you install only what you need, reducing context bloat and hallucinations.
V2 integrates with secure wallet providers for enhanced security:
import { TurnkeyWallet, PrivyWallet } from "solana-agent-kit/wallets";
// Turnkey - fine-grained rules and policies
const turnkeyWallet = new TurnkeyWallet({
organizationId: process.env.TURNKEY_ORG_ID,
privateKeyId: process.env.TURNKEY_PRIVATE_KEY_ID,
});
// Privy - human-in-the-loop confirmation
const privyWallet = new PrivyWallet({
appId: process.env.PRIVY_APP_ID,
requireConfirmation: true,
});
// Initialize agent with secure wallet
const agent = new SolanaAgentKit(turnkeyWallet, rpcUrl, options)
.use(TokenPlugin)
.use(DefiPlugin);
| Feature | V1 | V2 |
|---------|----|----|
| Wallet Security | Private key input | Embedded wallets (Turnkey, Privy) |
| Tool Loading | All 100+ tools | Plugin-based, load what you need |
| LLM Context | Large, caused hallucinations | Minimal, focused context |
| Human-in-loop | Not supported | Native with Privy |
solana-agent-kit-pyBuild professional financial services data packs from various sources including CIMs, offering memorandums, SEC filings, web search, or MCP servers. Extract, normalize, and standardize financial data into investment committee-ready Excel workbooks with consistent structure, proper formatting, and documented assumptions. Use for M&A due diligence, private equity analysis, investment committee materials, and standardizing financial reporting across portfolio companies. Do not use for simple financial calculations or working with already-completed data packs.
Give the AI agent its own EVM wallet with admin-controlled policies the agent CANNOT bypass even under prompt injection. Encrypted keystore (AES-256-GCM, scrypt KDF), policy file the agent has no tool to write, deterministic policy gate on every signing operation, optional local HTTP dashboard. Triggers: agent wallet, give the agent a wallet, agent address, fund the agent, agent autonomy, policy gate, kill switch, agent permissions, bounded autonomy, ERC-4337 alternative, session-key alternative.
BNB Chain MCP server connection and tool usage. Covers npx @bnb-chain/mcp@latest, PRIVATE_KEY and RPC, and every MCP tool — blocks, transactions, contracts, ERC20/NFT transfers, wallet, ERC-8004 agent registration, Greenfield. Use when connecting to bnbchain-mcp, querying or transacting on BNB Chain/opBNB/EVM, registering as ERC-8004 agent, or using Greenfield.
Entry point for Internet Court — the trust layer for agent-to-agent commerce. Use whenever an agent needs to transact with another agent or a paid service, or a user mentions agent payments, paid APIs (HTTP 402/x402), wallet custody or trust concerns, spending mandates, delegated permissions (ERC-7710/7715), escrow, agent identity or reputation (ERC-8004), negotiation between agents (A2A), agent jobs (ERC-8183), machine payments (MPP, AP2), supervision of agent behavior, revocation, verification, or dispute resolution (GenLayer) — even if they never say "Internet Court". Routes to the vendored protocol skills and connector skills in this package.
Upload files to IPFS through the Kleros x402 payment gateway in exchange for $0.01 USDC on Base mainnet. Use this skill **specifically** when the user is uploading content destined for the Kleros ecosystem — dispute evidence, meta-evidence JSON, court / dispute / arbitrator policies, Curate item metadata, juror justifications, or any artifact a Kleros smart contract or subgraph will reference by IPFS CID. Trigger when the request mentions Kleros, a court / arbitrator / dispute / juror / curate / proof-of-humanity context, or any of the conventional Kleros operation tags (evidence, meta-evidence, justification). Do NOT trigger for generic 'upload to IPFS' / 'get me a CID' requests with no Kleros context — point those users at Pinata, web3.storage, or any general-purpose pinning service instead. Exception: if the user explicitly names this gateway (kleros-ipfs-gateway.fly.dev / kleros-api.netlify.app/.netlify/functions/upload-to-ipfs), explicitly requests this skill, or asks the agent to test / validate / sanity-check this gateway or skill, trigger regardless of topical context — a deliberate end-to-end test is a valid trigger.
Use when an agent hits HTTP 402 / payment-required, or the user mentions x402, x402Version, X-PAYMENT, PAYMENT-REQUIRED, PAYMENT-SIGNATURE, WWW-Authenticate: Payment, permit2, upto, metered billing, a payment channel / voucher / session, channelId / channel_id, opening / closing / topping up / settling / refunding a channel, a paymentId or a2a_ link, creating / checking a payment link, A2MCP / an A2MCP endpoint, or sending a request to / calling an Agent's endpoint with a concrete endpoint URL. Covers x402 (exact, exact+Permit2, upto, aggr_deferred), MPP (charge / session), and a2a-pay paymentId flows. Any close / topup / settle / voucher / refund near a channel_id or session is an MPP mid-session op. The full bilingual trigger list (including Chinese) lives in the skill body.
Onchain OS onboarding & guide hub — the single entry for first-time, 'what is this / how do I use it', OKX.AI, and customer-support intents; classifies the intent and routes to the right sub-flow via its Intent Routing table. Covers: (1) Onchain OS onboarding + welcome banner — 'what is onchainos', 'what is onchain os', 'what can it do', 'what can onchainos do', 'what does onchainos do', 'how do I use this', 'how do I play', 'how to use onchainos', 'how to play onchainos', 'how does onchainos work', 'how do I start', 'getting started', 'tutorial', 'onboarding', 'first time', 'I just installed', 'now what', 'what do I do now', 'where do I start', 'who are you', 'what are you', 'introduce onchainos', 'tell me about onchainos', 'I'm new'; (2) OKX.AI intro & role-registration routing (the Agent economic system — roles User / ASP / Evaluator) — 'what is OKX.AI', 'OKX.AI 是什么', 'how to use OKX.AI', 'OKX.AI 快速开始', and any spelling / spacing / casing / typo variant (OKXAI, okx ai, okx-ai, lowercase okx.ai, 啥是okxai); (3) customer support / Help Center — 'contact support', 'talk to a human', 'customer service', 'file a complaint', 'give feedback', 'report a bug / system error', 'help center', 'FAQ', 'user guide', 'something is broken'. NOT for: direct on-chain actions (swap / wallet / balance / token) or Agent task lifecycle (publish / accept / deliver / dispute) — those have their own skills.
Create and manage Starknet wallets for AI agents. Transfer tokens, check balances, manage session keys, deploy accounts, and interact with smart contracts using native Account Abstraction.
Take sendaifun/solana-agent-kit from the repository into ~/.claude/skills for personal
use, or into .claude/skills inside a project.
The agent identifies a skill by the name field in its header. Two skills with the
same name cannot sit side by side — one of them will be ignored.
The instructions reference npm, npx.
Without those the skill loads but fails at the first command.
