MALALALA's DID Authentication Kit

Inspiration

Developers spend countless hours rebuilding auth infrastructure instead of core features, while users are overwhelmed by 'key chaos' and the friction of fragmented identities.

What it does

ChainAuth is a comprehensive developer toolkit designed to standardize and simplify decentralized identity across the Web3 ecosystem. By leveraging XRPL DID-based authentication, our SDK eliminates the traditional friction of dApp onboarding, allowing developers to integrate a robust, production-ready identity system into any application in under 30 minutes.

Instead of rebuilding authentication from scratch or relying on centralized gatekeepers, ChainAuth provides a sovereign-first solution that empowers users while reducing development overhead.

XRPL Features Used XLS-40d (Native DID Support) Usage: Used for complying with W3C DID standards directly on the ledger. How: The SDK implements the DIDSet transaction type to register and update DID documents. It also queries account_objects (type: did) to resolve DIDs, ensuring decentralized identity management without off-chain dependencies.

Memos (On-Chain Anchoring) Usage: Used for Verifiable Credential (VC) anchoring. How: When issuing a credential, the SDK calculates the SHA-256 hash of the credential and anchors it to the ledger using a standard Payment transaction (0 value or 1 drop) with the hash stored in the Memo field. Verification involves fetching the transaction and matching the Memo hash.

SignerListSet (Multi-Sig / Social Recovery) Usage: Used for the Social Recovery mechanism. How: The SDK allows users to designate "Guardians" by configuring a SignerListSet. This enables multi-signature functionality where a quorum of guardians can sign a transaction (e.g., SetRegularKey) to help a user recover their account if they lose their master key.

Issued Currencies (RLUSD Support) Usage: Used to demonstrate stablecoin payments. How: The SDK includes a payment manager designed to handle issued currencies (like RLUSD) by constructing Payment transactions with extended Amount objects (value, currency, issuer).

Event Subscriptions Usage: Used for real-time transaction monitoring. How: The SDK connects via WebSockets and uses the subscribe command to listen for account activity, allowing the UI to react instantly to on-chain events like incoming payments or recovery attempts.
