Tip Jar

Found Something Useful Here?

This site is a personal project — writeups, tools, and experiments built in my free time. If something here saved you an afternoon of debugging or sparked an idea, I'd appreciate a tip. No sign-ups, no middlemen, no tracking. Just crypto direct to my wallet.

(If you landed here from the 404 page: yes, the "Send $404 worth of Ethereum" thing is mostly a joke. But if you insist, the address is real.)

Jump to a coin:

Ethereum (ETH)

View on Etherscan

Ethereum mainnet only. Don't send from a different chain (Polygon, BSC, etc.) or it will be lost.

USDC (USDC)

View on Etherscan

USDC on Ethereum mainnet (ERC-20). Select USDC in your wallet before sending — do not send ETH or a wrapped token to this address.

Ethereum Classic (ETC)

View on Blockscout

Ethereum Classic chain (chain ID 61), not Ethereum mainnet. Shares address format with ETH but funds go to the wrong chain if you confuse them.

Bitcoin (BTC)

BTC address

Bitcoin Cash (BCH)

BCH address

Bitcoin Cash (BCH) — legacy address format. This is the same-format family as BTC but on a different chain; make sure your wallet is set to BCH.

Litecoin (LTC)

Litecoin mainnet.

Why Crypto?

Personal sites don't have a great fit with Patreon / Stripe / Ko-fi — those platforms take a cut, require account creation on both ends, and don't work internationally without friction. A wallet address is a URL; anyone with a wallet can send any amount, any time, no middleman.

Don't have crypto? No worries — the tools on this site are free. A Bluesky follow, a GitHub star, or sharing a CTF writeup is just as appreciated.
