TL;DR

• 1ST is an ERC-20 token on Base at 0x9a2891c8cbf90eb6ccb53dfeec9626c64ceb2c69.
• Public info is limited; it does not appear in major protocol lists yet.
• Verify everything on-chain first (supply, holders, liquidity, contract controls).
• Explore liquidity and activity across Base DEXs and trackers; always double‑check the contract address before trading.

Quick snapshot

• Symbol: 1ST
• Contract: 0x9a2891c8cbf90eb6ccb53dfeec9626c64ceb2c69
• Network: Base (an Ethereum Layer-2 using the Optimism stack)

At the time of writing, 1ST isn’t widely covered in top Base ecosystem roundups or aggregator listings. That typically means it’s early, niche, or experimental—common for meme and community tokens. Treat it as a research-in-progress and proceed with on-chain verification.

Base in two minutes

Base is an Ethereum Layer-2 developed with the Optimism stack and incubated by Coinbase. It aims for low fees, strong security inherited from Ethereum, and a developer-friendly environment.

• Activity highlights: over 1M daily active addresses and ~4M weekly active addresses as of June 2025; a record 13.39M daily transactions on January 1, 2025—showing high throughput potential.
• Fees and UX: Base uses ETH as gas (Base has no native token).
• Ecosystem: rapid growth in DeFi and meme tokens, with robust DEX volumes and retail-facing integrations on the horizon.

What we know (and don’t) about 1ST

• Contract confirmed on Base: 0x9a2891c8cbf90eb6ccb53dfeec9626c64ceb2c69
• Public docs: No widely cited website, whitepaper, or official socials were identified from the initial scan.
• Likely nature: Given the ease of minting on Base (e.g., no-code tools like Token Tool), 1ST looks like a custom ERC-20 rather than a core protocol token. Use on-chain data first, and consider community channels if/when they emerge.

Verify on-chain first (your DYOR checklist)

Use Basescan to check:

• Token supply and mint authority
  • Is minting disabled or capped? Who can mint?
  • Has ownership been renounced or transferred to a multisig?
• Holder distribution
  • Are top wallets concentrated? Any obvious team or deployer wallets holding large percentages?
• Liquidity profile
  • Which pools exist, on which DEXs? How deep is liquidity? Is liquidity locked?
• Contract safety signals
  • Trading taxes, blacklist/whitelist functions, pausable transfers, or upgradeability proxies.
• Recent activity
  • Transfers, new holders, large inflows/outflows, and timing around announcements.

Cross-check with market data aggregators (if listed) by searching the contract on CoinGecko or CoinMarketCap. If it’s not listed, that’s normal for new or niche meme tokens—on-chain data remains your primary source of truth.

Where to explore liquidity and trade on Base

If you decide to interact, always verify the exact contract address before swapping.

Recommended venues and trackers:

• GMGN.AI tracker and trading page for 1ST: https://gmgn.ai/base/token/fV1R5sZ5_0x9a2891c8cbf90eb6ccb53dfeec9626c64ceb2c69
• Aerodrome Finance (high-volume DEX on Base)
• Uniswap (supports Base)
• PancakeSwap (deployed on Base)
• BaseSwap
• SushiSwap

Note: Availability varies by token and pool creation. If you don’t see a pool on one venue, check others. For all swaps, paste the contract to avoid lookalike tokens.

Why GMGN.AI is handy for meme tokens

For fast-moving meme markets, specialized tools help you avoid obvious pitfalls:

• Real-time token pages with price, volume, and pool data
• Smart money and wallet activity tracking to spot trends early
• Automated trading tools and alerts (optional) via Telegram
• Basic safety checks like honeypot status or unusual taxes

Use these insights as a supplement—not a substitute—for your own on-chain verification.

Context: Coinbase’s Base DEX integration

Coinbase has announced plans to let users trade Base-chain tokens directly in the Coinbase app and website via integrated DEX functionality. With over 100M users, this could be a major unlock for liquidity and discoverability of Base tokens, including smaller or newer projects, once fully rolled out.

A practical research playbook for 1ST

1. Confirm contract and metadata
   • Start with Basescan. Check total supply, decimals, owner, and if the source code is verified.
2. Map liquidity
   • Identify which DEX pools exist, their depth, and who added liquidity. Look for lock/vesting details where applicable.
3. Analyze holder distribution
   • Top 10 wallets, deployer history, and any smart-contract-controlled addresses. Watch for concentrated or suspicious holdings.
4. Inspect the contract
   • Taxes, blacklists, maxTx/maxWallet limits, pausable transfers, or upgradeable proxies. These can affect tradability and risk.
5. Track on-chain flow
   • Monitor new wallets buying/selling, large inflows, and timing around news or social chatter.
6. Look for official channels
   • Search for an X (Twitter), Telegram, Discord, or a website tied to the exact contract. Verify links via the deployer’s official posts when possible.
7. Cross-reference price data
   • Check multiple sources (DEX UIs and trackers) to avoid stale or spoofed info. When in doubt, re-validate with raw pool reserves.

Base ecosystem backdrop

• Throughput and growth: Base has seen surging activity, including a 13.39M transactions day (Jan 1, 2025) and sustained daily/weekly active users into mid-2025.
• Costs and UX: Low fees and Ethereum alignment make Base a popular home for community/meme launches.
• No native Base coin: Fees are paid in ETH; any “Base token” claims should be treated skeptically unless from official sources.

Risks and reminders

• Illiquidity: Thin pools can cause extreme slippage.
• Centralized controls: Mint authority or admin keys can enable supply changes or trading limits.
• Taxes and honeypots: Trading taxes and restrictive logic can impair exits.
• Impersonation: Only interact with the exact contract: 0x9a2891c8cbf90eb6ccb53dfeec9626c64ceb2c69

None of this is financial advice. Meme tokens are highly volatile—size positions appropriately and double-check everything on-chain.
