TL;DR

• The MARV token at 0xf1a245691e45a416fedf0c1a75b0ba45c447b62c is reported to be on Base, but public data is inconsistent as of early September 2025.
• Multiple aggregators widely track “MARV” on Ethereum with different contract addresses; a Base-native MARV at this exact address is not clearly verified on major explorers or data sites.
• Treat this token as unverified until you confirm on-chain details yourself. We outline fast checks and safe trading steps below.

Why the confusion?

• Ethereum MARV exists: Major trackers list a “Marv/MARV” memecoin on Ethereum, not Base, and with different contracts. See references like CoinGecko’s MARV page and general coverage on CoinMarketCap.
• Base MARV uncertainty: Searches for the Base address 0xf1a2...b62c on BaseScan show limited or no verified metadata at the time of writing.
• Name overlap: Don’t confuse MARV with “Marvin on Base (MOB)” which is a different token, symbol, and contract.

Bottom line: either this Base MARV is very new, very niche, or misattributed. Proceed only after you verify the contract and liquidity on-chain.

Quick verification checklist (do this before any trade)

1. Contract on Base

   • Open the contract on BaseScan.
   • Check: token name, symbol, total supply, decimals, holders, recent transfers.
   • Look for verified source code and any proxy patterns (Upgradeable contracts can change behavior).

2. Liquidity and pairs

   • Inspect DEX pair contracts on Base (e.g., WETH–MARV).
   • Review pool size, recent volume, and who added liquidity. Thin or one-sided liquidity is a red flag.

3. Ownership and controls

   • Is ownership renounced? Any privileged roles (owner, admin, fee setters)?
   • Check for blacklist/whitelist functions, max-tx limits, or adjustable taxes.

4. Burn addresses and supply claims

   • If the project mentions burns, confirm tokens sent to a burn address (e.g., 0x000000000000000000000000000000000000dEaD) on-chain and see how much of supply is actually burned.

5. Cross-check aggregators

   • Compare the exact Base contract on multiple trackers. Ensure the chain and contract match the token page you’re viewing. Be wary of lookalike pages or mismatched chains.

What we know about “MARV” on other chains

• Ethereum MARV: Often presented as a pure meme coin (frog-themed, Pepe-adjacent), no-tax narrative, and large supply. It’s tracked on Ethereum with different contract addresses than the Base one above.
• Base MARV (0xf1a2...b62c): Sources conflict. Some mention pricing and availability, but explorer data and mainstream trackers do not consistently confirm a verified Base token at this address.

Treat any price you see for “MARV” as chain-specific. Always match the price feed and chart to the exact Base contract.

If you still plan to trade, do it safely

• Verify the contract again: 0xf1a245691e45a416fedf0c1a75b0ba45c447b62c on Base.
• Start small: Test with a tiny amount to confirm swaps can execute and tokens can be sold back.
• Watch slippage: Memecoins can be volatile; start with conservative slippage and widen only if necessary.
• Check approvals: Use your wallet’s approvals dashboard to revoke any risky token approvals after trading.
• Monitor liquidity: If liquidity is shallow or controlled by a single wallet, risk is high.

Recommended platforms to explore/token-page and trade:

• GMGN.AI token page for Base MARV: https://gmgn.ai/base/token/fV1R5sZ5_0xf1a245691e45a416fedf0c1a75b0ba45c447b62c
• Uniswap on Base (verify token before swapping): https://app.uniswap.org/swap?chain=base
• Aerodrome on Base (verify token before swapping): https://aerodrome.finance/swap

Note: Always paste the exact contract into the DEX token selector to avoid impostors.

How to spot red flags fast

• No verified contract or opaque source code.
• Trading works one way (you can buy but can’t sell) — classic honeypot behavior.
• Sudden, large ownership privilege changes or new proxy implementations.
• Extreme taxes or stealth changes to fees.
• Socials with low signal/no consistent announcements; mismatched contract addresses across channels.

MARV vs. “Marvin on Base (MOB)”

• MARV (this article): 0xf1a245691e45a416fedf0c1a75b0ba45c447b62c on Base — status unclear.
• MOB: Different symbol, different contract, separate narrative/use case. See its listing on trackers like CoinMarketCap.
  Make sure you’re not mixing these up — they are distinct tokens.

Final word

As of September 2025, the existence and status of MARV at 0xf1a2...b62c on Base remain uncertain in public data. If you’re interested, verify everything on-chain, confirm liquidity, and only trade via trusted interfaces after pasting the exact contract. For discovery and monitoring, use analytics and trading tools, including the GMGN.AI page above, and cross-check with BaseScan before making any decision.
