What Sporran is
The Sporran wallet allows you to manage your digital identities and
sign transactions with these digital identities on the KILT
blockchain as well as to manage your KILT DIDs and credentials
issued to them.
Therefore, with the full version you can:
Create a private/public key pair that represents your digital
identity, an off-chain DID for that digital identity and a backup
phrase for recovery
Create a password for each digital identity in order to access it
Check balances of your KILT Coins read from the blockchain or
Display the address of your digital identity via a string and a QR
code e.g. for copying or showing it to others for a transfer of
KILT Coins to your digital identity
Initiate and sign transactions with these digital identities to be
processed by the KILT blockchain
Use these digital identities with services that allow their usage
e.g. to initiate transactions and sign these transactions through
- Create on-chain DIDs out of the off-chain DIDs
- Receive credentials issued to your on- or off-chain DID.
- Check the status of your credentials. The status of a credential
can either be Pending (the attestation process has been started but
the credential has not been attested yet), Attested (the credential
is attested by the attester and is valid), Revoked (the attestation
of the credential has been revoked by the attester and the credential
is not valid anymore) or Invalid (when your DID is deleted all
credentials connected to it become invalid).
- Present your full Credential or parts of it. As a user who has an
on-chain DID and has created a credential with said on-chain DID, you
can present your attested credential. To do so, you download said
credentials in the “Manage on-chain DID” section inside Sporran. You
can choose here, if you want to present all the information from said
credential or use selective disclosure to show only certain information.
Once you click “continue” the credential will be downloaded as a json file.
This json file you can present by sharing it like any other file or you can
upload to and reference via a service endpoint.
In some versions of the Sporran, only parts of the listed features are enabled.
The data generated in and for your digital identities is stored
locally on your device. The balances displayed are based on the
information currently stored on the KILT blockchain. It is not
possible to know something about the DID by knowing something about
the KILT identity and vice versa.
When upgrading an off-chain DID to an on-chain DID, your credential
issued to it stays valid. An on-chain DID is written onto the KILT
blockchain. All information in your on-chain DIDs are publicly
available on the KILT blockchain. This includes the DID’s public
keys, the DID document with any information inside, e.g. if you have
added them service endpoints, web3name etc.
When removing your on-chain DID, you have no DID anymore. All
credentials issued to this Identity’s DID become invalid. You cannot
get new credentials for this Identity. The service endpoint is
written into the DID document. It consists of an URI with a type and
The web3name is a string unique to all DIDs on the KILT chain.
Please make sure you select a safe password and remember it.
If you forget your password or you are using a new device, you can
recover access to your digital identity only with your backup
IMPORTANT: If you lose your password and backup phrase, you will no
longer have access to your digital identity or the assets belonging
to that digital identity.
No one will be able to restore it for you. We have no knowledge of
your data, passwords or backup phrase.
Please write down your backup phrase correctly and in the correct
order and store it safely. Write it down with paper and pen and put
it somewhere that no one else can find and read it. Store your
backup phrase safely because it is your unique access to your
digital identity(s). If the backup phrase falls into the hands of
others, they will have full access to your digital identity and be
able to sign transactions on your behalf – and on other devices –
even without knowing your password.
If you lose your backup phrase you will not be able to recover
your digital identity,
for example when your device breaks or is lost.
B.T.E. BOTLabs Trusted Entity GmbH (hereinafter referred to as
"BTE") is liable for damages that are based on an intentional or
grossly negligent breach of duty by BTE, its legal representatives
or various agents.
In the event of a breach of essential contractual duties, BTE shall
only be liable for the contractually typical, foreseeable damage if
this was simply cause by negligence. Significant contractual
obligations are those whose fulfilment enables the proper execution
of the contract in the first place and whose compliance you can
regularly rely on.
The limitation of the two preceding paragraphs also apply to the
legal representatives and various agents of BTE, if claims are
asserted directly against them. The liability limitations resulting
from the two preceding paragraphs do not apply insofar as BTE
fraudulently concealed the defect or assumed a guarantee for the
quality of Sporran.
Liability for culpable injury to life, limb and health and liability
under Product Liability Act remain unaffected.
Any additional claims for damages are excluded.
The following risk information contains a list of risks associated
with the use of the Sporran wallet. The list is not exhaustive. It
is not excluded that further unknown or unpredictable risks exist.
Loss of backup phrase and password will result in a complete loss
of accessibility of the Sporran wallet in question.
At first: we have had two different security expert companies carry
out a security check (audit), each of which came to the conclusion
that the Sporran (software) is secure according to the current state
of the art. But: the further development in the information
technology and other computing sectors pose a threat to password
security and integrity of software-based-systems.
Sporran is installed on your system as a browser extension. For the
security of your password and backup phrase, it is essential that
your system is not compromised with malware. Please make sure that
this is the case, because malware running unnoticed in the
background, for example a key tracker, represents a major security
risk for you.
If you suspect someone knows your password or found your backup
phrase or if you are just uncertain about it, immediately open a new
digital identity with a different backup phrase, transfer your
assets to the new digital identity and make sure to clear and
terminate usage of your compromised digital identities.
Sporran communicates with the KILT blockchain and depends on its
functionality. Errors or dysfunctionalities, including failure of
the KILT blockchain or the technical ecosystem in which it lives,
may adversely affect the Sporran.
Sporran, and in particular the underlying software application, may
be the subject of hacking or other malicious interference by
unauthorised third parties resulting in the loss, theft or other
violation of data.
Because Sporran is built on open-source software, there is a risk
that a third party may unconsciously or knowingly incorporate errors
leading to potential adverse consequences for the usability and
functionality of the Sporran.
Communication via internet-based systems is fundamentally
susceptible to data/information being read out and possibly even
changed. We have no influence on which processes (now and in the
future) run in the background of the web browser used (Chrome,

BTE reserves the right to change the Software as well as the

any time for any future products in our sole discretion.
Such changes will be made via uploading new Terms and Conditions,
the Software and/or other information to the Website and any usage

and Conditions, will be handled by the new version of the Software
and will be for the commercial and non-commercial, while existing
Credentials acquired previous to this change shall remain untouched.
