SPACE ID is a decentralized name-service network that lets anyone register human-readable .<a href="/ja/price/bnb-bnb" target="_blank" class="blog_inner_link">bnb</a>, .arb, and .eth-style domains that map to wallet addresses, socials, and even website content hashes. The project’s native utility and governance token—ID coin—powers every auction, renewal, and DAO proposal inside the SPACE ID ecosystem. If you’re tracking airdrops, domain flips, or simply want a single identity across multiple blockchains, understanding how Space ID coin works can help you capture on-chain opportunities (and some handsome trading gains on Gate.io).
##How SPACE ID Solves the “Address UX” Problem
Copy-pasting <a href="/ja/price/0x-zrx" target="_blank" class="blog_inner_link">0x</a> strings is error-prone; Twitter handles are Web2 silos. SPACE ID introduces a one-stop identity layer that operates across BNB Chain, Arbitrum, and dozens of EVM networks. Once you mint, say, satoshi.bnb, you can:
- Receive BTCB, USDT, or any BEP-20 token by sharing your .bnb name.  
- Use the same handle to log in to <a href="/ja/web3" target="_blank" class="blog_inner_link">Web3</a> dApps that integrate SPACE ID SDK.  
- Display your domain on Gate.io’s profile badge (feature scheduled for Q3 2025).

All payments—registrations, renewals, sub-domain minting—are denominated in ID coin, anchoring token demand to real utility.

##Dual-Registry Architecture
SPACE ID runs two layers:
1. Universal Name Service (UNS) – a chain-agnostic database storing domain metadata; fast lookups via an off-chain indexer.  
2. Blockchain-Specific Registries – on-chain contracts for .bnb, .arb, .eth, etc., enforcing ownership and transfer logic.

Because UNS is abstracted, developers can resolve any ID-based domain with a single API call, whether the record lives on BNB Chain or Arbitrum One.

##Tokenomics Snapshot of ID Coin
|  Metric | Value (May 2025)  |
| ------------ | ------------ |
|  Ticker | ID  |
|  Total Supply |  2 000 000 000 |
|  Circulating |  606 M (≈ 30 %) |
| Inflation  | None; fixed supply  |
| Allocation  |  25 % ecosystem, 22 % staking rewards, 18 % team (36-month vest), 10 % Binance Launchpad sale, 25 % community + liquidity |

Each domain purchase burns 2 % of the ID spent; another 3 % routes to the DAO treasury, making ID coin mildly deflationary as registration volume grows.

##Core Use Cases Driving ID Coin Demand
- Domain Auctions & Renewals – Premium names like btc.bnb are bid exclusively in ID.  
- dApp Integration Fees – Projects embedding the ID Resolver stake tokens to reduce query costs.  
- DAO Governance – ID holders propose TLD launches (e.g., .sol) and vote on fee schedules.  
- Staking Yield – Delegate ID to node operators securing the UNS indexer; earn up to 12 % APR, payable in ID.

##Recent Catalysts for ID Coin Price
- Arbitrum .arb Launch (Jan 2025) – 1.2 M domains sold in 48 h, burning 1.8 M ID.  
- Gate.io Listing (Feb 2025) – Opened with zero maker fees; ID/USDT pair hit $120 M first-week volume.  
- Partnership with Galxe (Apr 2025) – Each on-chain credential now maps to SPACE ID domains; daily queries tripled.

##Roadmap 2025–2026
1. zkSync Deployment – gas-efficient TLD aimed at gaming guilds.  
2. Email-to-Earn Module – provably encrypted mailbox linked to your .id domain; sends cost a micro-fee in ID coin (burned).  
3. Gate.io Profile Integration – traders can display primary SPACE ID name on leaderboards and earn listing discount vouchers.

##How to Buy and Store ID Coin
- Gate.io Spot – Trade ID/USDT and ID/BTC with deep liquidity and instant settlement.  
- Gate Earn Staking – Lock ID to earn protocol fees without leaving the exchange.  
- Self-Custody – Withdraw to a BNB Chain or Arbitrum wallet; MetaMask and <a href="/ja/price/trust-wallet-twt" target="_blank" class="blog_inner_link">Trust Wallet</a> both support ID tokens.  

*Pro tip: Use Gate.io’s Auto-Invest to accumulate ID weekly; domain auctions often spike gas fees—having a stash ready means you won’t miss a premium handle.

##Risks to Watch
- Namespace Collision – Competing services (.bnb vs .bnbchain) could confuse users.  
- Regulatory Scrutiny – Domain resale may trigger securities debates in some regions.  
- Speculation Overhang – 40 % of .bnb registrations are investor-held; low renewal may hurt fee burn.

Always consider these factors before aping into ID coin on margin—Gate.io Futures provides up to 10× leverage, but risk management is key.

##Final Thoughts
SPACE ID turns the clunky 42-character wallet into a multi-chain Web3 username while giving ID coin clear, on-chain cash flows. With new TLDs, DAO fee switches, and Gate.io integrations on the horizon, ID has room to grow far beyond vanity domains.
Ready to secure your blockchain identity and trade the token that powers it? Create a Gate.io account, grab some ID coin, and claim your name before someone else does.
