Solana Token Due Diligence: How to Vet a Token Before You Buy

The first check on any SPL token is whether the mint authority and freeze authority have been revoked. A live mint authority means new tokens can be printed at will, diluting holders. A live freeze authority means individual wallets can be frozen — a common rug mechanic. Revoked authorities are not a guarantee of safety, but a live authority on a small-cap token is an immediate red flag worth a hard stop.

Pair this with a quick look at supply distribution. A token where the top 10 wallets hold the majority of supply can be dumped on you regardless of how strong the chart looks. NAVI surfaces concentration as a first-class risk signal so you do not have to reconstruct it from a block explorer.

Market cap is a vanity number for thin tokens; liquidity is what you can actually exit into. Look at the depth of the main pools on Raydium, Orca, or Meteora relative to the position you intend to take. A token can show a healthy market cap and still gap 40% on a modest sell if the pool is shallow.

The practical test: estimate the price impact of an exit at your intended size before you enter. If exiting would move the price meaningfully, the position is illiquid for you specifically — size down or skip. This single check prevents the most common avoidable loss on Solana.

Once supply and liquidity pass, judge whether current momentum is durable. Broad wallet participation and steady turnover suggest a move with follow-through; a spike driven by a few concentrated buys typically reverses fast. On memecoins especially, attention quality matters more than raw 24-hour volume.

Finally, define your invalidation before you enter — a maximum drawdown, a minimum liquidity threshold, and the condition that says 'this thesis is wrong.' Due diligence is not about finding reasons to buy; it is about finding the reasons not to, quickly, so your capital only meets the setups that survive the checklist.
