Question 1

How do I do a Solana token safety check?

Accepted Answer

Paste the token's SPL mint address into Sharpe's Rug Check. The scan queries the Solana RPC for mint authority, freeze authority, and update authority status; verifies liquidity lock on Raydium / Orca / Meteora; runs a Jupiter-based buy and sell simulation for Token-2022 transfer-hook honeypot detection; and analyzes top-10 holder concentration. A green-flag token has all three authorities renounced and liquidity locked for 6+ months.

Question 2

How do I rug-check a Solana token?

Accepted Answer

Same flow: paste the SPL mint address. Sharpe's scanner returns a 0–100 risk score with explicit findings on mint authority, freeze authority, update authority, LP lock, top-10 holders, and honeypot simulation. Copycat detection also runs automatically — if the token impersonates a canonical Solana ticker (BONK, WIF, JUP, etc.) and isn't the real contract, the scan flags it red.

Question 3

How do I verify a Solana token is real?

Accepted Answer

Three-step verification: (1) cross-reference the ticker against the Jupiter Strict List and the project's official Twitter, Discord, and website to find the canonical mint address; (2) check that the on-chain metadata hasn't been updated post-launch (retained update authority is a red flag); (3) run a Sharpe Rug Check on the mint address — copycat detection will flag any token with matching metadata that isn't the canonical one.

Question 4

What are Solana-specific rug patterns?

Accepted Answer

Mint authority not renounced (dev can print unlimited supply), retained update authority (metadata — name, symbol, image — can be swapped post-launch to impersonate another project), retained freeze authority (dev can freeze buyer wallets before dumping), pre-graduation bonding-curve dumps on pump.fun, expiring Raydium / Orca LP locks, and Token-2022 transfer hooks that reject outbound transfers (SPL-style honeypot).

Question 5

Is pump.fun safe?

Accepted Answer

The pump.fun bonding-curve infrastructure is reasonably safe — pre-graduation liquidity is held in curve contracts that devs can't pull directly. The per-token risk is high: most tokens never graduate, and among those that do, many have post-graduation dumps from insider wallets accumulated during the bonding-curve phase. Use rug check plus on-chain holder clustering before sizing meaningfully. Post-graduation tokens trade as standard SPL on Raydium and are subject to the full Solana rug-risk surface.

Question 6

Can Solana memecoins be rugged after graduation?

Accepted Answer

Yes. Post-graduation tokens trade as standard SPL on Raydium AMM and inherit the full risk surface. Devs who retained any authority can still exploit — mint unlimited supply (if mint authority retained), freeze wallets (if freeze authority retained), swap metadata to impersonate another project (if update authority retained), or dump concentrated holdings. Always verify all three authorities are renounced, even on graduated tokens, and cross-check LP burn / lock status on Raydium.

Question 7

What is Token-2022 and why does it matter for rug checks?

Accepted Answer

Token-2022 is a Solana token standard extension that adds optional features like transfer hooks, transfer fees, confidential transfers, and interest-bearing tokens. Most features are legitimate, but transfer hooks can reject outbound transfers — effectively implementing an EVM-style honeypot on Solana. Sharpe's Rug Check detects Token-2022 extensions, runs a Jupiter-based sell simulation, and flags any hook program that rejects outbound transfers. Plain SPL tokens don't support this attack, but Token-2022 tokens do.

Question 8

Is Sharpe's Solana rug check free?

Accepted Answer

Yes. The Sharpe Solana Rug Check is 100% free, with no signup required. Every SPL and Token-2022 scan — mint / freeze / update authority verification, LP lock check, holder concentration analysis, copycat detection, and Jupiter honeypot simulation — is available at zero cost. Results are available via the public REST API and MCP server for developers building bots or AI agents.
