How It Works?

Somnia Domain Services (SDS) is powered by a simple yet secure smart contract deployed on the Somnia Shannon Testnet.

Users claim names like erick.som by paying a fixed fee (1 STT). This fee is paid in Somnia's native token, and the name is permanently associated with their wallet address.

The contract enforces the following logic:

🧱 Core Mechanics

• Only 1 name per wallet is allowed

• Names are case-insensitive (all normalized to lowercase)

• Names are unique and cannot be re-claimed

• Registration requires exactly 1 STT

• The STT payment is stored in the contract and withdrawable by the owner (deployer)

🔗 Public Functions

• claimName(string) – Claim a domain (only once, requires 1 STT)

• resolveName(string) – Get the wallet address of a .som name

• reverseLookup(address) – Get the .som name assigned to a wallet address

• isAvailable(string) – Check if a name is available

💰 Withdrawals

The contract deployer (owner) can call withdraw() to transfer all collected STT fees to their wallet.

🧠 Domain Rules

• Names shorter than 3 characters are rejected

• .som suffix is automatically added in logic

• All names are stored as full .som strings (e.g. erick.som)
