Rainbow Token (RBW): Uses, Supply and Risks

Rainbow Token (RBW) was the token associated with Crypto Unicorns when the game was on Polygon. It is distinct from tokens with similar names or symbols, including RNBW associated with the Rainbow crypto wallet. Checking the ticker alone is not enough to identify a token; the network and contract address matter too.

RBW is now a legacy token. Crypto Unicorns migrated from Polygon to XAI in May 2024, and the project described the transition as a move toward a new token, Crypto Unicorns (CU), on Arbitrum and XAI. That means RBW should not be assumed to be the current game token or to have the same uses as CU. Public sources identify RBW’s earlier connection to the game but does not establish current gameplay functions or ongoing support.

RBW’s known purpose was to serve as the token for Crypto Unicorns during its time on Polygon. Public sources do not specify a full list of token functions, such as whether it could be used for particular game actions, governance, or staking. It is therefore safer to describe RBW as a former game token than to assume it retains utility in the migrated game.

The May 2024 move to XAI brought a new token, CU, into the project’s stated direction. RBW and CU should be treated as separate assets unless the project’s current official materials explicitly say otherwise. Do not assume that holding RBW gives you CU, that the tokens can be exchanged one-for-one, or that old Polygon balances remain usable in the current game. Migration arrangements can change, so check current project information before acting on any claim about conversion or eligibility.

The reported maximum and total supply of RBW is 1 billion tokens. Circulating supply is about 999.8 million, leaving little difference between the reported circulating and maximum amounts. These figures describe token supply, not demand, trading activity, or whether the token is supported by Crypto Unicorns today.

As of 2026-11-04, RBW was reported at about $0.00044 per token, with a market capitalization of about $438,000. Reported 24-hour trading volume was about $1, an especially low figure that can make a quoted price difficult to trade at in practice. Prices and market figures change, and low-volume assets may have wide spreads or limited buyers and sellers. The historical figures do not indicate what RBW may be worth in the future and should not be treated as a forecast.

RBW is listed as issued on Polygon; it is not identified as the native token of a blockchain. The later Crypto Unicorns migration involved XAI, with CU described as the new token on Arbitrum and XAI. This distinction matters when checking a wallet balance or considering whether a token belongs to the old Polygon deployment or the newer project setup.

A Polygon-compatible wallet may be able to display or hold an ERC-20-style asset, but wallet compatibility does not confirm that a token is official, active, or usable in the game. Before sending RBW, verify the network and contract address against current, official project information. Never use a contract address copied from an unsolicited message or a token with a similar name. No contract address or current official storage instructions are established here, so confirm those details independently before interacting with the asset.

RBW carries the risks of a legacy token: the project may no longer support its former use, trading may be very limited, and it may be confused with unrelated tokens that have similar names. The migration to CU does not by itself establish that RBW can be converted, redeemed, or used in the current Crypto Unicorns game. Treat claims of guaranteed conversion or active utility with caution and verify them through current project channels.

The reported trading volume was about $1 as of 2026-11-04, so a displayed price may not reflect a price at which a meaningful amount can be bought or sold. There is also the usual risk of sending tokens on the wrong network or interacting with a counterfeit contract. These details are not a recommendation to buy, sell, or hold RBW. If you already have the token, check the project’s current guidance and your wallet’s network and contract details before taking action.
