TL;DR

• The address 0x4c14935d488c8e6108714aa21e661fdb4ddae307 on the Base chain is labeled “ONE CARD,” but public data is sparse and major aggregators don’t show a clear token profile or active markets.
• Many are confusing “ONE CARD” with the Coinbase One Card—a traditional credit card product—not a tradable crypto token.
• Treat this address as high-risk/unknown until verified. Use explorers and liquidity tools to confirm any real trading activity before interacting.

What we found about the address

Our checks across Base chain data sources—including BaseScan, Blockscout, and OKLink—did not surface a widely indexed token profile or notable liquidity for “ONE CARD” at 0x4c14935d488c8e6108714aa21e661fdb4ddae307. That usually means one of the following:

• The token is extremely new or inactive.
• Liquidity is very low or pools don’t exist yet.
• The token hasn’t been indexed by popular data providers.

In parallel, we found similarly named tokens on Base with different addresses, reinforcing the need to match by contract, not name.

Why the confusion happens

• Coinbase markets the Coinbase One Card (an American Express® credit card) that gives Bitcoin rewards. It’s connected to the Coinbase ecosystem, which includes the Base network, but it is not itself a tradable token.
• Some listings and community chatter conflate “ONE CARD” with Coinbase’s credit card perks, creating the impression of a token where official documentation doesn’t confirm one.

How to verify the token

If you’re assessing 0x4c14935d488c8e6108714aa21e661fdb4ddae307, follow a simple checklist:

• Confirm contract metadata on BaseScan or Blockscout:
  • Token name and symbol
  • Decimals and total supply
  • Verified source code and contract owner
• Check holder distribution:
  • Look for concentrated holdings (top wallets >50% is a red flag).
  • Identify smart contracts or liquidity lockers involved.
• Inspect liquidity:
  • Are there any pools on Base DEXes (e.g., Aerodrome)? If not, practical trading may be impossible.
• Scan social and dev signals:
  • Official website, X/Twitter, GitHub, or community channels tied to this exact address.
  • Consistent branding and disclosures.
• Run security heuristics:
  • Taxes above ~10%, blacklist functions, or proxy upgradability without timelock all increase risk.
  • Honeypot behavior (cannot sell) should be checked before any buy.

Is “ONE CARD” tied to Coinbase One Card?

Some commentary suggests a link between the address and Coinbase’s credit card rewards. However:

• The Coinbase One Card is a traditional financial product, not a blockchain-tradable token.
• There’s no confirmed, official statement that the Base address above is an onchain representation of card rewards or utility. Treat such claims as speculative unless Coinbase publishes formal documentation.

Where to monitor or trade (if liquidity exists)

If you discover real liquidity for this address and still want to explore:

• Use GMGN.AI’s ONE CARD page to track price, holders, and smart money flows.
• Paste the contract into DEX UIs like Uniswap or Aerodrome to check for pools and simulate trades.
• Use charting tools (e.g., DEXScreener) by searching the contract address to confirm real pairs and volume.

Important: Always paste the exact contract address when searching. Do not rely on token names alone.

Practical safety tips for meme tokens

• Verify contract and liquidity before interacting with any token.
• Prefer wallets with spending caps and revoke approvals after testing.
• Start with tiny test transactions to check for sellability and taxes.
• Use multiple data sources to avoid spoofed or fake listings.
• Document findings (screenshots, links) so you can repeat checks over time.

Bottom line

Right now, “ONE CARD” at 0x4c14935d488c8e6108714aa21e661fdb4ddae307 doesn’t present clear, publicly verifiable evidence of an active, widely traded token on Base. Given the naming overlap with Coinbase’s credit card, proceed cautiously, validate onchain details directly, and don’t trade based on branding or assumptions alone. If credible liquidity emerges, track it with tools like GMGN.AI and confirm everything via explorers and reputable DEX interfaces before risking capital.
