<Update label="May 15, 2026" tags={["launch"]}>
  ## ArcPass launch week

  This week, ArcPass shipped its first public release: an end-to-end sponsorship platform that covers the first transaction for new Arc Network wallets.

  ### New features

  * **Sponsorship platform MVP** — Submit a wallet address and receive native tokens for your first Arc Network transaction. See [Request sponsorship](/guides/request-sponsorship) to get started.
  * **On-chain sponsorship registry** — Every completed sponsorship is now recorded on Arc testnet through the `SponsorshipRegistry` contract, so you can verify any grant independently. Learn more in [Smart contracts](/concepts/smart-contracts).
  * **Automatic relay execution** — Approved sponsorship requests are picked up by the relay and delivered to your wallet with no further action required. Read about the flow in [How it works](/how-it-works).
  * **End-to-end sponsored execution** — The full lifecycle from request through `approved`, `relayed`, and `completed` is now live. See [Sponsorship lifecycle](/concepts/sponsorship-lifecycle).
  * **Public REST API** — Wallet registration, sponsorship requests, status lookups, and relay endpoints are available. Browse the [API reference](/api-reference/overview).
  * **Sponsorship dashboard** — Track requests and verify on-chain delivery from the [dashboard](/guides/dashboard).

  ### Updates

  * **Production hardening** — Stricter input validation, per-wallet and per-IP rate limits, and improved error responses across the API. See [Rate limits](/configuration/rate-limits).
  * **Runtime validation suite** — Added end-to-end runtime checks so service health and configuration are continuously verified.
  * **Standardized API proxy** — Unified the request path so the frontend and external integrations share a single, consistent API surface.

  ### Fixes

  * Stabilized the sponsorship flow and runtime configuration loading, reducing failed requests during high traffic.
  * Fixed worker runtime issues on the Arc testnet configuration so relayed transactions land reliably.
  * Resolved status-tracking edge cases where requests could stall between `approved` and `relayed`.
