We are building infrastructure that allow applications to solve account abstraction and customise the experience any way they want for the novel interesting use-cases

Accounts

Instead of storing all you DeFI positions and NFT holding in one single wallet embrace the concept of (mini) accounts

Spotify creates an account for you to keep track of your music liking
IMDB creates an account for to follow what movies & shows you like
X creates an account that keeps track of people and topics that is interesting to you

You can sign-in in all of these service with your email or Google but they don’t store all this information related to their services on you big Blob Email ID.

Why are we keep doing it with our wallets? Creating a new Account for each Dapp makes it

More secure
More private
More fun

What we are doing

Standards

Our repository contains new standards for:

Signing in with you accounts
Interaction with accounts
Creating and keeping of accounts (on-chain)

Libraries

Our authentacation library has data structures, verification logic and other utilities for simplifying life for future account applications.

The list of credentials we verify:

Ethereum (EVM) personal sign
Cosmos Arbitrary (036)
Passkeys / Webauthn
(WIP) JWT / Oauth / Social Sign
Secp256k1 / Secp256r1 / Ed25519 Curves

[Future] Integrate with other enterprise solutions like Abstract SDK, Vectis, Nomos, Obi and others for enhanced security and other cool features

Applications

Proxy Accounts

Onboard users who only have a Metamask, Phantom or other non-native wallet to your Cosmos (Cosmwasm) application

Create a proxy account in form of a smart contract with native address
Store DeFI, NFTs and other positions on the proxy account
Only allow withdrawals and other operations provided an Ethereum, Solana or other signature
Make the proxy accounts reusable for all other dapps thanks to the on-chain registry

Token-Bound Accounts

Have accounts linked to Non-Fungible Tokens
Allow any existing or future NFT to get its own address
Allow your token to hold balances or even other tokens
Create a concept of tradable account allowing you to sell any bulk of assets or positions
Protects against cheating on Marketplaces
