# Altana Skills > Protocol know-how for AI agents on BNB Chain. Every skill is one markdown file > teaching an agent how to use a protocol correctly, tested by Altana on a fork of > mainnet before it is listed, and always executed inside a session scope the wallet > owner sets. Free to use. ## What a skill is A skill is a Reference (addresses, quirks, function signatures) plus a Playbook of named plays an agent can run. It is not code an agent installs; it is know-how the agent reads and then acts on through its own tooling. Onchain writes go through an Altana session, which enforces an allowlist and a spend cap and can be revoked in one transaction, so a skill can never move funds outside what its owner permitted. ## How an agent gets these Through MCP, which is the intended path: - Install: `claude mcp add altana -- bunx @altananetwork/mcp` - `search_skills({ query })` returns matching skills from this registry - `get_skill({ id })` returns the full SKILL.md and verifies its sha256 against the registry before handing it over, so tampered content is refused rather than returned Or over plain HTTPS, with no MCP server involved: - [Registry JSON](https://skills.altana.network/index.json): every skill with its id, description, scope, version and sha256 - [Full catalog text](https://skills.altana.network/llms-full.txt): all 10 SKILL.md files in one fetch - Individual source: `https://skills.altana.network/skills//SKILL.md` - Canonical raw registry: https://raw.githubusercontent.com/altananetwork/skills/main/index.json ## Skills - [PancakeSwap Trading](https://skills.altana.network/skill/pancakeswap-trading): Buy and sell tokens on PancakeSwap on BNB Chain through an Altana session. - [Four.meme Trading](https://skills.altana.network/skill/four-meme): Snipe and trade memecoin launchpad curves on Four.meme, and hand off to PancakeSwap after graduation. - [PancakeSwap Liquidity](https://skills.altana.network/skill/pancakeswap-liquidity): Provide and withdraw PancakeSwap V2 liquidity to earn trading fees on your token pairs. - [Copy Trade](https://skills.altana.network/skill/copy-trade): Mirror a chosen wallet's PancakeSwap trades under hard per-trade and total caps. - [Venus Lending](https://skills.altana.network/skill/venus-lending): Lend stablecoins on Venus Protocol on BNB Chain through an Altana session. - [x402 API Payments](https://skills.altana.network/skill/x402-payments): Pay for APIs and services over HTTP with the x402 protocol from an Altana session. - [Lista Liquid Staking](https://skills.altana.network/skill/lista-staking): Stake BNB for slisBNB on Lista and earn staking yield while staying liquid. - [Aave V3 Lending](https://skills.altana.network/skill/aave-v3-lending): Supply USDT to Aave V3 on BNB Chain to earn yield, and withdraw on command. - [Token Radar](https://skills.altana.network/skill/dexscreener-token-radar): Find trending BNB Chain tokens and screen them for liquidity and risk before trading. - [Wallet Tracker](https://skills.altana.network/skill/wallet-tracker): Watch any BNB Chain wallet's trades live, profile its recent activity, and find a token's early buyers. ## Submit a skill Anyone can publish one.
