XPR Network Developer Skill

This skill provides comprehensive knowledge for developing on XPR Network, a fast, gas-free blockchain with WebAuthn wallet support.

Policy for AI agents (applies skill-wide): All chain writes documented in this skill use the proton CLI keychain for signing — private keys stay in the CLI's on-disk keystore (proton-cli.json in the CLI config dir), never in the agent's process memory or context. That file is plaintext until you run proton key:lock <password> — treat locking as a required step on any long-lived host, not an option. Reads use direct RPC (get_table_rows, get_account, etc.) and the relevant project's REST API. Do not introduce signing patterns that pass raw private keys to the agent (e.g. new JsSignatureProvider(['PRIV_KEY']), wallet.import_key('...'), XPR_PRIVATE_KEY in environment). See backend-patterns.md → Security: Key Isolation and ../agent-bootstrap.md for the canonical signing path.

AI-generated contract code: smart contracts are immutable once deployed and hold real assets, so treat any contract code produced with this skill as a draft. Before it reaches mainnet it needs testnet runs, review by a developer who knows XPR Network/EOSIO contracts, and, for anything holding significant value, a professional audit. The full checklist lives in safety-guidelines.md → AI-Generated Code Disclaimer.

Network etiquette (applies skill-wide): XPR Network has no fees, so chain spam is free to send and costly for everyone else. Agents write to chain only when there is a concrete action to take, never to scan or probe; default ceiling 6 transactions per minute per account, one in flight, exponential backoff on failure, no nonce actions, no account fleets. Liquidation, sniping, and MEV-style bots are out of scope and deliberately undocumented; decline requests to build them. Full rules: safety-guidelines.md → Network Etiquette.
