bTokens (tracker certificates by Backed Assets (JE) Limited, ”b” tickers, winding down)
What the client owns
A debt certificate of Backed Assets (JE) Limited that tracks an ETF or share; the holder has a claim on the collateral set aside for that product, not on the ETF or share. Third-party synthetic: A note or swap that pays like the security and carries no rights in it.
Who may hold it
Not offered to US persons. First purchase $6,076. The issuer sells new certificates itself only to Qualified Professional Investors; retail investors subscribe only through an Authorized Participant. The minimum subscription is CHF 5,000 (USD 6,076 at the ECB rates of 23 September 2026), plus investor fees of up to 0.5% and at least CHF 100; there is no management fee. In Switzerland the certificates may go to professional investors only. US persons are barred. A holder who bought on a secondary market needs no onboarding to hold, but must pass the issuer’s KYC to redeem. The public offer was not carried into the 8 May 2026 base prospectus, and Backed is winding the line down by the end of 2026; onboarded clients may swap into the matching xStock or redeem for stablecoins.

How it exits
Redeem with the issuer in its window. Redemption Order to the issuer at any time after KYC; the Tokenizer de-activates the tokens and the issuer pays the cash redemption amount, less investor fees of up to 0.5% (at least CHF 100), by the fifth business day (T+5). The issuer may call a product on 30 business days’ notice, 50 bps fee. Settles in CHF, USD, stablecoins.
This file replaced an earlier record on 2026-09-29. The file listed bTSLA on Solana without a reading of who controls the token there. This version adds that reading, so a client wallet holding it now matches this file. Superseded records.
Subscribers see which of their clients hold this program, each household’s answer against these terms, and an alert when the file changes. $49 per advisor per month, first 14 days free.
The verdict is on the memo: bTokens (Backed Finance, winding down) Rejected
Other programs tokenize the same securities. Every version side by side: COIN, NVDA, TSLA.
Who may buy, hold, transfer, and redeem
Each answer rests on the issuer’s own words, quoted from the document named under it. Ketju re-reads each document and records whether the words are still there. Where the documents say nothing, the row says so.

- Who it may be transferred to

Who holds the keys
Every current holder of each power, read from the chain on 2026-09-29. A single key is one private key: whoever holds it acts alone. A multisig needs the stated number of signers. A timelock makes every action wait, so holders can see it coming.

Where it trades
| Venue | Kind |
|---|---|
| Backed Assets (JE) Limited, directly and through Authorized Participants | issuer primary |
| CoW Swap and other decentralized venues | dex |
How it exits
| Path | Settlement | Fee | Settles in |
|---|---|---|---|
| Redeem with the issuer in its window | Redemption Order to the issuer at any time after KYC; the Tokenizer de-activates the tokens and the issuer pays the cash redemption amount, less investor fees of up to 0.5% (at least CHF 100), by the fifth business day (T+5). The issuer may call a product on 30 business days’ notice. | 50 bps | CHF, USD, stablecoins |
| Redeem with the issuer in its window | Wind-down swap: onboarded clients swap bTokens for the matching xStock with the issuer (equities 1:1; bCSPX to SPYx; bC3M, bIB01, bIBTA and bHIGH to TBLLx at a ratio the issuer sets), until the end of 2026. | xStocks | |
| Secondary market only; no issuer redemption | Holders without issuer onboarding sell on decentralized venues such as CoW Swap, or swap into xStocks there. | USDC, xStocks |
- Backed ends the wind-down: redemptions or swaps close, or the issuer calls a product
- Any bToken proxy points at a new implementation, or its owner multisig or proxy admin changes
- The sanctions list owner (a single key on Ethereum, Polygon and Arbitrum) blocks a holder, or an implementation adds a freeze or a wider burn
- The custodian, security agent, or Tokenizer changes
- A bToken appears in a new base prospectus or supplement, or the minimum or fees change
- An implementation changes on any chain
Reopen conditions: events that change an answer above
What the monitor reads daily
Every control function in the table above and the contracts the token consults on transfer; the token’s on-chain supply against yesterday’s; and its market quote against yesterday’s quote. Every document quoted above is re-read too, and a quote that leaves its document reopens the file. A key that appears, disappears, or changes shape counts as a change only when the chain’s own log shows the grant, revocation, or signer change between yesterday’s block and today’s; a difference the log does not show updates this file’s key list and nothing more. A change opens a review item in the governance queue and reopens the file before any client action. Subscribers get an email naming each of their clients who hold it, with the household result.
File history
Revised 4 times since it was filed. Each superseded copy is kept as published, with the reason it was replaced.
| Date | Change |
|---|---|
| 2026-09-23 | Filed. |
| 2026-09-24 | Revised. Superseded to record the Avalanche contract’s freeze and allowlist powers, marked unverified when the explorer did not answer. The verified source now read shows both; the Avalanche contract has no clawback, as the file already said for the other chains. |
| 2026-09-24 | Revised. Superseded to correct the allowlist and settle the BSC powers the file had marked unverified. The allowlist the file recorded as true came from delegateWhitelist, which only controls who may relay a transfer a holder signed, so no chain has an allowlist. BSC’s implementation has no verified source there but is the same code as the verified Arbitrum implementation at the same address: it can freeze a holder and cannot claw back. |
| 2026-09-27 | Revised. Superseded to add control readings on chains the file listed without one, so a wallet holding the token there matches the file and the daily watch reads it. The terms and the claim model did not change. |
| 2026-09-29 | Revised. The file listed bTSLA on Solana without a reading of who controls the token there. This version adds that reading, so a client wallet holding it now matches this file. |
