Model and inspect cryptographic wallet-bound software licenses for Chrome extensions, SaaS apps, and downloadable plugins.
Generate sample ES256 (ECDSA P-256) license tokens, verify expiration and wallet binding, and copy drop-in verification snippets for @xpayr/extension-kit (v0.2.0) and MCP agents.
When a buyer completes a non-custodial crypto payment on XPayr, License Kit issues an asymmetric ES256 (ECDSA P-256 SHA-256) signed JWT containing the product slug, license tier, buyer wallet address, session ID, and expiration timestamp. Your extension, desktop app, or SaaS backend can verify this token offline using your public key or online via @xpayr/extension-kit (v0.2.0).
Yes. The XPayr 21-Tool MCP Server exposes xpayr_issue_wallet_license and xpayr_verify_wallet_license on both npx -y @xpayr/mcp-server and POST https://xpayr.com/api/mcp.
Browser extensions, desktop apps, and downloadable WordPress/WooCommerce plugins cannot safely store a shared HMAC secret without exposing it to reverse engineering. With ES256, XPayr signs the license with a private key and your client-side software verifies it using only a safe public JWK.
