Twenty thousand tokens in staking unlock the top cashback tier and at the same time give you a share of the fees withheld from those who leave the pool. Two streams instead of one — and that is what makes this farming rather than a simple fee refund. Below is the arithmetic on live data, and an honest account of where it breaks down.

You buy 20,000 RNBW, put them into staking — and from that moment you earn from two independent sources at once.
Rainbow charges 0.85% on every swap made inside the app. On the top cashback tier that fee comes back in full, in RNBW tokens. The swaps you make anyway stop costing you the wallet's fee.
When any staker takes their position back, the contract withholds 10% and distributes it to everyone who stayed. This is the pool's only income, and it does not depend on anything you do. The rate right now is …, and over the past month it averaged ….
They do not interfere: cashback is credited for your swaps, pool income for other people's exits. At a swap volume of five thousand dollars a month they come to roughly 127% a year in tokens on the twenty thousand you put in.
The main caveat, and it is not a formality here. All of this income is counted in tokens, not in money. If RNBW falls further than the interest accrues, you end up down in dollars at any yield. That is not theory: since its launch in December 2025 the token has fallen several times over.
The difference is fundamental, and many people get it wrong. Cashback on its own cannot bring you more than you spent: it refunds a fee, which at best puts you at zero on that fee. Making a profit on cashback alone is impossible by construction.
The fees withheld from leavers, though, are income. They come from other people rather than from your own spending, and they accrue even if you have not made a single swap. You end up with more tokens than you bought.
That is why the two streams together produce triple-digit percentages in tokens: one closes your costs, the other adds on top.
| Source | Where the money comes from | Depends on | Can it put you ahead |
|---|---|---|---|
| Cashback | your own 0.85% fee | your swaps | no, only breaks even on the fee |
| Pool income | fees withheld from leavers | other people's exits | yes |
That is the threshold of the top BLACK tier with a full refund. At the current price it is about 470 dollars. The tiers below give 75%, 50% and 25% at thresholds of 15,000, 10,000 and 5,000 tokens. Buying happens inside the app, described step by step in how to buy and stake RNBW.
Searching for the RNBW ticker turns up more than one token — Base contains a fake with the same name and icon. There is only one real address:
0xa53887F7e7c1bf5010b8627F1C1ba94fE7a5d6E0
The tier is determined by your staking position, not by your wallet balance. Simply holding the tokens is not enough — they have to go into the contract 0x288ea8Bcb51d53aD361D786EFa904C401904aF70. In the same place as cashback, in the app's rewards section.
The RNBW pool is small. A purchase of a few hundred dollars already moves the price against you, and the result comes out worse than the quote. If the sum matters to you, break it into several goes — how much is in the pool right now is on the Earn page.
Calculated for 20,000 RNBW in staking. Pool income is taken at the most conservative of our rates — 18.5% a year, the 90-day average; over 30 days it came to 25.2%, and the instantaneous rate after large exits rose above 28%.
| Your swap volume | Pool income | Cashback | Together, a year | On what you put in |
|---|---|---|---|---|
| $500/mo | 3,702 RNBW | 2,172 RNBW | 5,874 RNBW | 29.4% |
| $2,000/mo | 3,702 RNBW | 8,688 RNBW | 12,390 RNBW | 62.0% |
| $5,000/mo | 3,702 RNBW | 21,721 RNBW | 25,423 RNBW | 127.1% |
| $20,000/mo | 3,702 RNBW | 86,882 RNBW | 90,584 RNBW | 452.9% |
Pool income is the same on every row — it depends only on the size of your position and on how many people are leaving. What grows down the table is cashback, and it grows in proportion to your swaps.
The 0.85% rate is for swaps, and the calculation above rests on them. Trading perpetual futures in Rainbow costs 5 basis points, that is 0.05%: seventeen times less, and cashback on the same volume will be correspondingly smaller. How trading fees find their way into cashback cannot be checked from outside — trading rewards are computed by Rainbow's server rather than by the contract, and its answers are not publicly readable.
Where the pool income comes from, in units. Twenty thousand tokens are 0.074% of the current pool. Right now about … RNBW a day goes to those who stayed, and your share of that is roughly 16 tokens a day. No new shares appear in the process: every existing one simply becomes worth more.
Three cases in which the arithmetic above stops working. Check them before buying, not after.
Cashback is proportional to volume, and without swaps only pool income is left. For reference: the median address receiving cashback does 180 dollars of swaps a year — we reconstructed that from the full history of allocations. At that volume a year of cashback will not even reach two hundred tokens, and the whole thing rests on the pool alone.
On exit the contract withholds 10% of the entire position — not of the profit, but of everything sitting there, accrued earnings included. On twenty thousand that is 2,000 RNBW. To recover that withholding alone at a rate of 18.5% you have to stay 197 days. Leaving earlier is a guaranteed loss in tokens.
Interest accrues in RNBW, not in dollars. A yield of 127% a year in tokens turns into a loss in money if the price halves over the same year. There is a historical precedent, and a recent one.
You can only exit with the whole position. The contract forbids partial withdrawal: you cannot take out half, only everything at once and with the fee withheld from the full amount. That is worth weighing when choosing how much to put in — depositing more than you are prepared to leave alone costs more here than it looks.
The yield on RNBW staking depends not on how many people joined, but on how many left. Inflows push it down — the same stream of coins is split across a larger pool. Outflows push it up, and twice over: the pool shrinks, and a tenth of whoever left is added to it.
Hence the shape of the yield chart: flat stretches broken by jumps. Every jump is somebody's large exit. After one, the elevated rate holds for up to seven days while what was withheld is distributed, and then it settles back. The mechanism is taken apart in why the distribution window is never longer than seven days.
The flip side is the same thing. If nobody leaves at all, pool income drops to zero: it has no other source. The rate is guaranteed by nobody and nothing — it merely reflects what is happening in the contract right now.
Not one figure above requires trusting us — all of it is read straight from the blockchain.
