Tip Jar

For crypto tips: before you send

• Send only ETH or USDC on Ethereum or Base to the address above. Anything else, or any other network, may be lost permanently.
• Check the first 6 and last 4 characters after pasting: 0x14bF…d973a. This site is the only place our address is published.
• A tip is a voluntary gift. You get nothing in exchange: no goods, services, access, tokens, rewards, returns, profit or ownership of any kind.
• A tip is not an investment or a security. Tips are not connected to any token or coin and give no rights, returns or perks. We will never DM you asking for crypto.
• Blockchain transfers are irreversible, so tips are final and can't be refunded. If you send a duplicate or mistaken tip, tell us within 14 days at [email protected] and we'll consider returning it, minus network fees. You pay any network (gas) fees.
• We are not a registered charity, and no tax receipts are issued. You're responsible for your own taxes.
• By tipping you confirm that you are 18 or older (or the age of majority where you live), that you're using your own funds lawfully, and that you are not a sanctioned person or acting for one. We may return or report tips that raise fraud or sanctions concerns.
• The wallet address is published only on this site; Jakub never asks for funds by DM. Jakub never DMs anyone first and never asks for seed phrases or private keys.
