What Is RugCheck?

Definition

RugCheck is a Solana token analysis tool that automatically evaluates token safety by checking mint authority, freeze authority, LP burns, holder distribution, and other rug pull risk factors.

RugCheck (rugcheck.xyz) is the most popular safety scanner for Solana tokens. Traders use it to evaluate whether a token is likely safe or a potential rug pull before buying.

  • Mint authority — is it revoked? (safe if yes)
  • Freeze authority — is it revoked? (safe if yes)
  • LP status — are LP tokens burned or locked? (safe if burned)
  • Top holders — does any single wallet hold too much supply?
  • Metadata mutability — can the token info be changed? (safer if immutable)
  • Creator activity — has the creator made other tokens? Were they rugs?
  • Good — all authorities revoked, LP burned, distributed holders
  • Warning — some concerns (e.g., mutable metadata, large holder concentration)
  • Danger — major red flags (active mint authority, LP not locked, 1 whale wallet)

To get a "Good" rating on RugCheck for your CoinDevTools token, the free route is to leave the Revoke Mint, Revoke Freeze, and Metadata Lock toggles on during creation (they default to on and cost nothing extra): 1. Revoke mint authority (free, on-by-default toggle at creation; 0.1 SOL via the standalone tool for an existing token) 2. Revoke freeze authority (free, on-by-default toggle at creation; 0.1 SOL via the standalone tool for an existing token) 3. Make metadata immutable (free, on-by-default toggle at creation; 0.1 SOL via the standalone tool for an existing token) 4. Burn LP tokens (free tool, either way) 5. Ensure no single wallet holds >10% of supply

Rug Pull
A rug pull is a type of crypto scam where a token creator removes all liquidity from a DEX pool, crashes the price to zero, and disappears with the funds.
Mint Authority
The mint authority is the wallet address authorized to create new tokens for an SPL token on Solana. Revoking it permanently locks the token supply.
Freeze Authority
The freeze authority is the wallet address that can freeze (prevent transfers of) any token account for an SPL token on Solana.
Liquidity Lock
A liquidity lock permanently prevents anyone from removing tokens from a DEX liquidity pool — achieved by burning LP tokens or sending them to a dead address.
