Build and ship x402-session powered dapps using Elsa capabilities. Now featuring Sign once, settle many times.
More possibilities
Applications you can build when payments are a session, not a popup - games, chat, and AI on Base.
Games & interactive apps
Arcade flows, loot boxes, and turn-based play: each action can settle against a session cap instead of signing every move.
Chat-based sessions
Authorize USDC once; every message or tool call debits the session off-chain and on-chain via the facilitator with no repeated wallet popups.
AI inference & APIs
Meter LLM and backend endpoints with x402: clients attach a session id; you price per token, per call, or per minute.
Micropayments at scale
ERC20 approvals bound total spend; the facilitator enforces per-call limits and recipient binding for many small settlements.
Paywalled routes
Protect Next.js routes and APIs with the same session scheme—verify and settle through a standard facilitator HTTP API.
Composable experiences
Mix chat, games, and inference in one product: one session wallet UX, consistent headers, shared facilitator infrastructure.
