Stake moves two needles at once: the tip dial falls toward zero while the rate dial rises.

Your effective rate

Your tip and your rate limit are both derived from your active stake, so they change when your stake changes. Read the current values for any wallet:

  "wallet": "7xKX…",
  "staked_relay": 25000,
  "tip_sol": 0.0006311,

Field	Meaning
`staked_relay`	Active stake, in whole $RELAY
`tip_sol`	The tip this wallet owes per transaction, in SOL
`tip_lamports`	The same tip in lamports — use this as your transfer amount
`base_tip_sol`	The unstaked tip, so you can show the saving
`rps`	Requests per second currently allowed
`max_stake_relay`	Stake at which the tip reaches zero and rps its ceiling

A few points on the curve, for calibration:

Active stake	Tip per transaction	Rate limit
0	`0.001 SOL`	`5 rps`
10,000	`0.00084487 SOL`	`35 rps`
25,000	`0.00063110 SOL`	`77 rps`
50,000	`0.00032988 SOL`	`136 rps`
100,000	`0 SOL`	`200 rps`

No authentication is required — stake is public on-chain state. A wallet that has never staked reads as staked_relay: 0 with the full tip and the 5 rps floor, rather than an error.

Read it before you build your tip. Hardcoding 0.001 SOL works but overpays once you stake. Fetching tip_lamports and using it for the transfer amount means the same code keeps working as your stake grows.
