Binance Wallet just dropped Agent ID registration - basically an on-chain username system with permanent binding.

Key specs:
• Non-transferable (locked to wallet address)
• Globally unique namespace
• First-come-first-served allocation
• No secondary market possible due to transfer restrictions

Technically this is a soulbound token implementation - similar to ENS but without the tradability layer. The immutability makes it pure identity infrastructure rather than a speculative asset.

If you want a clean handle or vanity ID, grab it now before the namespace gets cluttered with random strings.
