WBETH, BNSOL and other receipt tokens: how they grow
Stake ETH on Binance and you get WBETH; stake SOL and you get BNSOL. Both are receipt tokens: what appears in your account is not the coin you put in but a token standing for your share. Both are rate-appreciating — the count stays put while each token redeems for more ETH or SOL over time. The first reaction is usually “where did my asset go”. It did not go anywhere — what you hold is a claim on it.
The mechanism is simple enough, but it drags three consequences behind it: how the token grows, why it can trade below the value of what backs it, and the fact that you have two exits rather than one.
What a receipt token is
Take Ethereum staking. The ethereum.org staking pools page states that most transparent pools issue a liquid staking token — an ERC-20 that represents a claim on the staked ETH and the rewards it earns.
“Claim” is the load-bearing word. The token in your wallet is not ETH; it is a receipt saying a share of ETH plus accrued rewards sits underneath. There is a layer between the receipt and the thing. Most of the time that layer is invisible. Occasionally it is not.
The pattern is not unique to staking. Any product that hands you a token representing a share has the same shape; only the underlying and the operator differ.
Two ways it grows: rebasing versus rate-appreciating
Receipt tokens pass yield to you in one of two ways, and mixing them up produces wrong arithmetic:
- Rebasing. The number of tokens you hold increases on its own; each one keeps the same share of the underlying. The count visibly grows — intuitive, but each change is an event you may need to record.
- Rate-appreciating. The count stays fixed and the exchange rate moves: each token redeems for more of the underlying over time. Nothing in the balance changes, and the gain shows up as “one token is now worth more”.
Neither design is better. They feel completely different, though. Rebasing looks like growth; rate-appreciating looks like nothing is happening, which regularly convinces people the product has stopped earning when the gain is simply living in the ratio rather than the count.
Telling them apart is direct: after some time, check two numbers — how many tokens you hold, and how much underlying one token redeems for. Whichever moved tells you the type.
Binance’s own three receipt tokens line up neatly (Binance ETH Staking help page and the SOL Staking FAQ, checked October 2026; ratios are whatever the product page shows at the time). WBETH is rate-appreciating: Binance says 1 WBETH represents 1 staked ETH plus the staking rewards accrued since 2023-04-27 08:00 (UTC), the WBETH:ETH ratio updates daily at 00:00 (UTC), and rewards are not paid to your Spot Wallet. BETH is the rebasing kind: rewards arrive as BETH in your Spot Wallet daily from T+2. BNSOL is rate-appreciating too, with the BNSOL:SOL ratio updated every Solana epoch, roughly every 2–3 days. Binance gives an illustrative example: at a ratio of 1:1.01004105, staking 10 SOL gets 9.90058770 BNSOL; three months later the ratio is 1:1.01980774 and the same BNSOL redeems for 10.09669596 SOL. The BNSOL count never changed; the extra SOL lives entirely in the ratio.
Why the distinction changes your records
If you keep yield records, the two types record differently. Every rebase is a datable event. With a rate-appreciating token, nothing happens to the count until you redeem or sell — the gain materialises in one step at exit.
That changes when you can say what you earned, and what you can produce if records are ever required. How to keep them is covered separately in yield income records; the point here is narrower: identify which type you hold before choosing how to record it.
One more caution: a growing token count is not the same as growing value in your own currency. The underlying still rises and falls — the same distinction as in coin or dollar terms.
Receipt tokens can trade at a discount
This is the layer most often missed. The ethereum.org page states plainly that because these tokens trade freely, their market price may diverge from the value of the ETH backing them, and lists “the secondary-market price of the token may fall below the value of the ETH backing it” as a market and liquidity risk — noting it is more pronounced during periods of market stress.
The reason is structural. A secondary-market price is set by whoever is buying and selling right now, while the underlying claim may only be redeemable through a process that takes time. When many holders want out immediately and the orderly route involves a queue, whoever takes the token off your hands will want a discount for it.
So “this token is liquid” and “this token converts at face value” are two different statements. The first usually holds. The second is not guaranteed — least of all in exactly the conditions where you most want out.
Two exits, priced differently
- Redeem through the protocol or product. Hand the token back and receive the underlying at the current ratio. You get what you are owed, but there may be a wait, and how long depends on the rules and queue at that moment.
- Sell on the secondary market. Immediate proceeds, at whatever the market pays — possibly below the backing value. You are buying immediacy with a discount.
Neither is the good option and neither is the bad one; it is a fast-versus-full trade. What actually hurts is not knowing both exist — people wait when they needed speed, or pay a discount when they were not in a hurry.
Before deciding, put two numbers side by side: what selling gets you now, and roughly how long redeeming takes plus what it returns. Waiting periods and rules are whatever the product or protocol page says at the time; this article gives no durations.
Receipt-token mechanics, exchange ratios, redemption waits and whether secondary trading exists differ by product and protocol; all of it is whatever the official page says when you open it, and this article gives no specific durations or ratios. A receipt token’s market price can fall below the value of what backs it, the underlying itself fluctuates, and a growing token count is not the same as growing value in your currency. Yield and staking can lose principal. Independent third-party material; not investment advice.
