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 and no claim on the ETF or share itself. 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. The terms bar US persons. A holder who bought on a secondary market needs no onboarding to hold, but must pass the issuer’s KYC to redeem. The 8 May 2026 base prospectus does not carry the public offer forward. Backed is winding the line down by the end of 2026, and onboarded clients may swap into the matching xStock or redeem for stablecoins.

How a holder redeems
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 by the fifth business day (T+5), less investor fees of up to 0.5% (at least CHF 100). The issuer may call a product on 30 business days’ notice, 50 bps fee. Settles in CHF, USD, stablecoins.
This file replaced an earlier version 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. Earlier versions.
Subscribers see which of their clients hold this program and whether each household qualifies under these terms, and Ketju emails them when the file changes. $299 per firm per month, first 30 days free.
The verdict is on the memo: bTokens (Backed Finance, winding down) Not approved
Other programs tokenize the same securities. Every version side by side: COIN, NVDA, TSLA.

Each answer quotes the issuer’s own words from the document named under it. Ketju reads each document again and records whether the words are still there. Where the documents say nothing, the row states that.

Who controls it
Ketju read these powers from the deployed contracts and their verified source code: the token and every contract it checks on a transfer. A power listed here is something the issuer can do; it does not mean the issuer has used it.

Who holds the keys
Ketju read every current holder of each power from the chain on 2026-09-29. A single key is one private key, and whoever holds it acts alone. A multisig needs the stated number of signers. A timelock delays every action, so holders can see it before it takes effect.

Where it trades
| Venue | Kind |
|---|---|
| Backed Assets (JE) Limited, directly and through Authorized Participants | issuer primary |
| CoW Swap and other decentralized venues | dex |
Redemption
| Route | 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 by the fifth business day (T+5), less investor fees of up to 0.5% (at least CHF 100). 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
Review triggers
Daily checks
Every day Ketju reads each control function in the table above and the contracts the token checks on a transfer. Ketju compares the token’s on-chain supply with yesterday’s, and its market quote with yesterday’s quote. Ketju also reads every document quoted above and reviews the file again if a quoted passage disappears from its document. Ketju counts a new, removed, or changed key as a change only when the chain’s own log shows the grant, revocation, or signer change since yesterday. If the log does not show it, Ketju updates the key list in this file and does nothing more. A change opens a review before any client action. Subscribers get an email that names each of their clients who hold the token, with the household result.
File history
Ketju has revised this file 4 times since filing it. Ketju keeps each earlier version as published, with the reason for the change.
| 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. |
