Common questions

Is xsolana safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.20.1) reached the registry 8 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

solana-kit

The tools for loot, one shared Solana program for game and community economies. This repository is the npm package @xgamesfun/solana:

a JavaScript client with no Solana SDK (@xgamesfun/solana/client), a player module for apps (/play) and a results client (/results);
the economy spec and its checker, quick simulation, cost and plain-words explainer;
the xsolana CLI and an MCP server with ten xsolana_* tools;
the xsolana-economy skill, and one plugin that carries the tools and the skill to Claude Code and Codex;
a local approval page where a project's owner approves going live in their own wallet.

An economy is a JSON spec, not a new smart contract. Every project shares the one program, and none writes its own.

Status: loot 0.22.0, program ID 9cwqM1TXytPnFZsLfmUyv2dg4uW6Ch9C6UJVPns7NFQ, devnet only. The program is

not independently audited, and nothing runs on mainnet until it is. See SECURITY.md.

Disclaimer: provided as is, with no warranty and no guarantee that the program or the tools are safe. Use them

at your own risk; you are responsible for every transaction you approve and for making sure what you build is legal

where it runs. Nothing here is legal or financial advice. Read DISCLAIMER.md before you use it.

What an economy can be made of

payments and splits, in tokens or with an NFT
shops (a purchase in one transaction) and loot boxes
pools and timed schedules, sealed or not
lotteries and raffles, including no-loss lotteries
prizes of any kind on every route, random or not: items, tokens, and NFTs the project holds in a stash
an NFT as the price on every route that takes money
staking farms with lock tiers, boosts, early exits and tolls
crafting recipes
holds and contests, with prizes by rank or by stake
auctions: the highest bid wins, the outbid refunded at once
listings for sale or rent, and bids and loans between players
perks, staking and holds for any NFT, whether the project has authority over it or not
allowlists of any size (a Merkle list) on every gated route
capped rewards and grants that a server vouches for
rules on what a collectible says

Every move leaves a public receipt. docs/program.md describes how the program behaves.

Use it from an AI coding agent

The MCP server and the skill let Claude Code, Codex or any MCP agent turn a one-line idea into a checked, simulated economy and hand you the command that puts it live in your own wallet.

Claude Code

/plugin marketplace add XGamesFun/solana-kit

/plugin install xsolana@xgamesfun

Codex

codex plugin marketplace add XGamesFun/solana-kit

codex plugin add xsolana@xgamesfun

Any agent with MCP (Cursor, opencode, Cline…): run the server with npx -y --package=@xgamesfun/solana@0.22.0 xsolana mcp. Or let npx -y @xgamesfun/solana@0.22.0 connect register it, with the skill, for Claude Code and Codex.

Then ask for an economy, for example *"a fishing game where each cast costs 0.02 SOL, with a rare golden fish and a monthly draw"*.

Going live is always yours: npx -y @xgamesfun/solana@0.22.0 approve opens a page on your computer where you connect a devnet wallet and approve each transaction. The agent never signs and never asks for a key.

Use it from a terminal

Every tool runs from the CLI too, on a spec file (xsolana.json by default):

npx -y @xgamesfun/solana@0.22.0 examples shop with loot boxes   # the nearest worked examples

npx -y @xgamesfun/solana@0.22.0 check xsolana.json # refusals and warnings npx -y @xgamesfun/solana@0.22.0 simulate xsolana.json # where the money goes, day by day npx -y @xgamesfun/solana@0.22.0 cost xsolana.json # what going live and each action cost npx -y @xgamesfun/solana@0.22.0 explain xsolana.json # the economy in plain words npx -y @xgamesfun/solana@0.22.0 approve xsolana.json # go live, approved in your own wallet

xsolana help lists every command. Every command names the exact version, so npx runs that release and never whatever is newest under the name.

Use it from code

npm install @xgamesfun/solana

import * as loot from '@xgamesfun/solana/client';

const ix = loot.openBoxIx({ player, project, box, nonce }); // one builder per instruction, no Solana SDK

Import	What
`@xgamesfun/solana`	the economy tools: `check`, `simulate`, `plan`, `cost`, `explainEconomy`, `model`
`@xgamesfun/solana/client`	every PDA, one builder per instruction, account and receipt decoders, grant vouchers
`@xgamesfun/solana/play`	`solanaApp`: what a player does with a live economy, from a browser app
`@xgamesfun/solana/results`	results and vouchers a game's server signs
`@xgamesfun/solana/chain/*`	browser-safe Solana primitives: base58, Borsh, transactions, PDAs, tokens, Core
`@xgamesfun/solana/idl.json`	the program's IDL, the authority for account and argument layouts
`@xgamesfun/solana/release.json`	the program build, IDL and client this release is pinned to

The client, chain and play modules run in browsers and Node 22 or later, with no bundler required. The package ships TypeScript declarations for every entry point.

Documentation


`docs/program.md`	the program: who signs, accounts, every instruction, fees, limits, receipts, costs
`docs/nfts.md`	NFTs and tokens, with and without the project's authority
`docs/harnesses.md`	how the plugin reaches Claude Code and Codex, and the release checklist
`skills/xsolana-economy`	the skill an agent follows
`examples/`	whole economies that check and go live in the tests; `ideas.json`, 112 real economies rated
`evals/`	fresh-session evals of agents building on loot
`CHANGELOG.md`, `SECURITY.md`	versions, the trust model, reporting a vulnerability

Layout

Path	What
`js/chain/`	browser-safe Solana primitives, no SDK
`js/client/`	the client; `idl/` is the program's IDL
`js/economy/`	the economy spec (version 2, `schema.json`), checker, simulation, setup plan, cost, explainer, guide
`js/play/`, `js/results/`	a player's side of a live economy; results a server vouches for
`js/approve/`, `js/mcp/`, `js/connect/`	the approval page, the MCP server and its tools, `xsolana connect`
`js/sim/`, `js/test/`	LiteSVM running the real program; the tests and their pinned fixtures
`bin/xsolana.mjs`	the CLI
`skills/`, `plugin/`	the skill (copied to `plugin/skills`, `.claude/skills`, `.agents/skills`) and the plugin
`scripts/`	fixtures, skill sync, IDL sync, release manifest, a devnet end-to-end run
`release.json`	the program binary, IDL and client hashes this version is pinned to

Development

Node 22 or later.

npm ci

npm run fixtures # downloads the loot program from devnet and the programs it calls from mainnet, each checked by hash npm test # every instruction the client builds, and every example's whole setup, against the real program in LiteSVM npm run lint # ESLint npm run check # fixtures, skill copies and release.json in step, lint, then the tests

Nothing in the tests deploys or spends SOL.

Variable	What it does
`XSOLANA_RPC_URL`	a devnet RPC of your own for `xsolana approve` and `xsolana status` (a mainnet URL is refused)
`XSOLANA_NO_OPEN`	`xsolana approve` prints its link without opening a browser
`XSOLANA_DEBUG`	the CLI prints a failure's whole stack, not one line

| XSOLANA_PROGRAM_DIR | the tests run that program build's target/deploy/loot.so, and check the IDL against it | To try the tools in your own agent from a clone, node bin/xsolana.mjs connect --local registers this checkout's MCP server and the skill with Claude Code and Codex (--remove takes them out again).

After editing skills/, run npm run sync-skills. Changes to tool texts, the skill or the plugin are best measured with the evals before and after (evals/README.md). AGENTS.md has the rules for working in this repository, for people and coding agents alike.
