TL;DR
A rug pull is a scam where a token creator abandons a project after extracting liquidity or investor funds, leaving holders with worthless tokens.
A developer creates a token, generates hype through social media and fake communities, and waits for buyers to pour in liquidity. Once enough value accumulates in the pool, the developer removes the liquidity (or sells a massive pre-held supply), crashing the price to near zero. On Solana, the speed and low fees of the chain make rug pulls particularly fast — a token can launch, pump, and rug within minutes.
Watch for anonymous teams with no track record, locked or missing social media accounts, concentrated token holdings (a single wallet holding 20%+ of supply), no liquidity lock, and freshly created deployer wallets. Tools like RugCheck and Solana’s on-chain data make it possible to verify these red flags before buying.
A hard rug is an immediate liquidity drain — the developer pulls 100% of pooled SOL in one transaction. A soft rug is slower: the team gradually sells their holdings, stops development, or quietly exits over days or weeks. Both end the same way for holders, but soft rugs are harder to detect in real time.
Always check the deployer’s history using tools like Deployer Hunter. Look at the token’s holder distribution, verify that liquidity is locked or burned, and avoid tokens with concentrated insider wallets.
