AirGap LPT Delegation

[pascuin]

Give a 3 sentence description about this proposal.

With AirGap we focus on keeping assets safe and stored offline on a dedicated mobile device, this is especially beneficial for staking assets. Having your LPTs truly secured offline and delegated to a Transcoder is the most secure approach.

Describe the problem you are solving.

Delegation of LPTs with a straight forward approach with safe offline storage is not solved yet. With AirGap's solution, which has been already applied in other staking environment like Tezos and in the near future Cosmos, this will be a thing of the past.

Describe the solution you are proposing.

AirGap has already established itself as a wallet with the focus on accessible security, enabling its users to safely store their assets on a device completely cut off from any networks. This brings a new kind of security to the user as he generates a private key that has never touched the internet and securely stores it in the secure enclave of a mobile device only accessible by biometrics.

In AirGap this is made possible with a two device approach, where one device is taken offline after the installation of the AirGap Vault application. A new private key is then generate and stored on that device. On the other hand on an ever-day smartphone the companion application AirGap Wallet is installed which is responsible for the communication with the internet and the blockchain protocols. For example, a new delegation transaction is being prepared in AirGap Wallet by selecting the transcoder's address, a QR code with the transaction details are generated which is scanned by AirGap Vault and signed by accessing the secure enclave with the biometrics. The signed transaction is displayed on AirGap Vault as a QR code, scanned and broadcasted by AirGap Wallet.

More information about AirGap can be found on our website.

Describe the scope of the project including a rough timeline and milestones**

For the integration of LPT and enabling of the delegation the following milestones are relevant:

M1

Integration of the LPT token in AirGap Wallet & AirGap Vault

Prerequisites Existing Ethereum integration in the airgap-coin-lib, AirGap Vault and AirGap Wallet

Expected Deliverables AirGap Wallet & AirGap Vault support for LPT

M2

Creating, signing and broadcasting LPT transactions to send LPT tokens

Prerequisites LPT token is integrated in the airgap-coin-lib

Expected Deliverables The user can send LPT tokens from to another account and sign the transactions with AirGap Vault.

M3

Delegation to transcoder flow

Prerequisites LPT integration: transaction creation, signing and broadcasting support

Expected Deliverables The user can select a transcoder from a list and select it as a delegator and sign the delegation transaction with AirGap Vault.

M4

Security audit and testing

Prerequisites Complete LPT integration with delegation support.

Expected Deliverables Fully tested and audited code of the LPT integration.

Please estimate hours spent on project based on the above

28 hours a week for 4 weeks
