🌉 Alien Gateway

Send crypto to @username on Stellar

Alien Gateway is a **Stellar Naming Service ** — a decentralized, privacy-preserving username system for crypto payments on Stellar.

What It Does

Maps @username → wallet address
Enables payments using human-readable names
Works natively with Stellar payments and memos
Prevents wrong-address transfers
Preserves user privacy using ZK proofs

Why SNS

Wallet addresses are long and error-prone
Users manage multiple wallets across chains
Public name registries leak identity data

SNS treats usernames as a core payment primitive, not just metadata.

How It Works

User registers @username
Username is stored as a ZK commitment, not plaintext
Availability is proven using Circom ZK proofs
Username resolves to a wallet at payment time
Stellar transaction is routed with memo support

Zero-Knowledge Design

Usernames are never stored on-chain in plaintext
Existence / non-existence is proven via ZK
Registry is backed by a Sparse Merkle Tree
Only a single Merkle root is anchored on-chain

Core Components

SNS Registry (Soroban)
- Stores commitments
- Anchors Merkle root
ZK Verifier
- Verifies Circom proofs
Wallet Resolver
- Maps username → wallet
- Supports exchange memos

Use Cases

Wallet payments
Exchange deposits
DAO payouts
Creator tipping
Cross-border transfers

Vision

One username. One identity. Stellar-native.

Alien Gateway aims to be the identity and payment resolution layer for the Stellar ecosystem.
