Is JAM live on Polkadot?

No. Official Polkadot documentation describes JAM as an envisioned successor to the current Relay Chain. Treat it as a roadmap and verify implementation status before relying on it.

What replaced parachain auctions?

Agile Coretime. The official Wiki states that auctions stopped on-chain in September 2024 and leaseholders were migrated to bulk coretime.

Is DOT staking yield fixed?

No. Rewards depend on validator activity, commission and network conditions. A displayed APY is not guaranteed and can change.

What does shared security mean?

Polkadot's validator set helps validate connected parachain blocks. It does not make every application, bridge or token risk-free.
