Testing the waters on@fiverr

I’ve just put up my NFT Character Pack, packages aren’t fully fleshed out yet, but if you’re curious or want something custom, hit me up.

No gas? No problem.
GasPump is live! 🔥
It’s a tool I’ve been building with @anhquan715 that lets you swap tokens for $VTHO, even when your wallet has none.

We sponsor the gas so you can always transact.

Diving into honeypots and scam tokens (for research purposes, of course! 🧐)

Just came across this post on the Salmonella honeypot – pretty interesting! Check it out: https://t.co/g2PqiUpgM8

Any other recommendations on the topic? Let me know!

@kuprumion @kuprumxyz Congrats! Well deserved

[Feder @fede_rodes]

My first 3-digit payout! It’s not a lot, but it feels like progress.

With this result, I think I can start judging on @sherlockdefi 🧐 That’s going to be interesting.
