How does Stake-Weighted QoS (SWQoS) work?

A leader reserves ingress capacity for staked peers. An RPC operator may establish a trusted arrangement with a validator so traffic is associated with stake-backed connections, subject to configuration.

What should trading bot developers know about Stake-Weighted QoS (SWQoS)?

SWQoS governs ingress capacity rather than guaranteeing transaction inclusion or a fixed execution order. It is distinct from transaction prioritization fees and Jito bundle auctions.
