SuperLumio cannot be reached. Its connection points do not respond, its explorer is down, and independent monitoring lists it as archived and no longer maintained.
Its own website and documentation still publish working-looking connection details with no notice of any of this.
No shutdown was announced, so this looks like abandonment rather than a closure with a process.
What you get out of the box
Pick your import method.
Before you start
- Add the wallet you bridged from. That side of the transfer is still recorded on the chain you sent from.
- Gather your purchase records and anything you exported before it became unreachable.
On Kryptos
- Log in to Kryptos.
- Go to Integrations.
- Click Add Integration, then search for and select SuperLumio.
- Click the SuperLumio icon and choose Upload CSV.
- Upload the file. Kryptos reads it and categorises the transactions for you.
Good to know
- Gas here was ETH rather than a token of its own.
- The project's site still publishes connection details. The network behind them does not respond.
- No shutdown announcement exists, so there is no official date.
A website that outlived the chain
SuperLumio was a layer 2 network launched in 2024 and described by its own team as a trial mainnet. It is no longer reachable: its connection points do not respond, its explorer is down, and independent monitoring lists it as archived and no longer maintained.
What makes it worth a page is the gap between that and its public presence. The project's website and documentation are both still up, still describe the network in the present tense, and still publish connection details that a user would reasonably try. Nothing on either indicates a problem.
That pattern shows up repeatedly among abandoned chains, and it is worth internalising as a general lesson: a working website tells you nothing about whether a chain is running. The only reliable test is whether the network itself answers and produces new blocks.
For anyone with a position here, the practical position is the familiar one for an abandonment. There was no announcement, no withdrawal window and no official date, so a claim rests on evidence you assemble: what you moved onto the chain, when, what it cost, and that the network no longer functions. The transfer that funded it is still recorded permanently on the chain you sent from, and that is usually the strongest piece. See the USA crypto tax guide or the UK crypto tax guide for how losses of this kind are treated.

Documenting what you moved across
The transaction that sent assets onto this chain is still recorded permanently on the chain you sent from.
Accounting for a stranded balance
Assets on an unreachable chain are a worthlessness question rather than a sale.
Establishing what you paid
Cost basis now comes from exchange records and anything you saved yourself.
Audit-ready, automatically.
Once your wallets and exchanges are connected, generating a tax report takes a single click. Open Reports from the menu, choose your jurisdiction, and download.
Stranded assets are not a disposal
Nothing was sold. Whether a loss can be claimed depends on where you file and usually on evidence the asset is unrecoverable.
No announcement means no clean date
Without a published shutdown, there is nothing official marking when the position became worthless, so your own evidence matters more.
The bridging record survives
The outbound transaction on the chain you sent from is permanent and shows the amount and the date.
A live website is not a live chain
The project's site and documentation still respond and still publish connection details. That is not evidence the network works.
Read-only by design.
- A file upload is read-only. Nothing connects to your account
- Kryptos never asks for your password or login details
- Delete an import at any time and its data goes with it
- Keep the original file: it is your evidence if anyone asks later
If something doesn't sync.
Its connection points do not respond and its explorer is unreachable.
It is still published and still lists connection details. The network behind them does not answer.
There is not one that we could find. The chain appears to have been left rather than closed.
