Testnet beta. Uzo Deploy is live on BOT Chain testnet (chain 968). Mainnet is not enabled yet. Everything here is free to try with test tokens from the faucet.
Tested, not audited. Uzo Deploy’s templates are built on OpenZeppelin Contracts and have full test coverage, but they have not had a professional audit. Start on testnet, and on mainnet use amounts you can afford to lose.
Deploy a tip jar and get a link people can use to tip you in USDT or BOT, with a short message. To share it and see tips, read Tip pages.

​
What it does

  • Every tip goes directly to the recipient in the same transaction. The contract never holds a balance.
  • Tips can be in USDT or BOT (tBOT on testnet).
  • Each tip can carry a public message of up to 140 bytes. It’s stored on chain for anyone to read.
  • The jar has no owner. Nobody, including you, can change the title or the recipient after deployment.
  • Plain transfers to the jar’s address are rejected. Tips have to go through the tip page, or a call to tipNative or tipToken.

Form fields

Check the recipient on the Review step. If it’s wrong, deploy a new jar.

​
How a USDT tip works

USDT on BOT Chain doesn’t support signature approvals (permit), so a USDT tip takes two transactions:
  1. Allow. The tipper approves the jar to move exactly the tip amount. The app never asks for an open-ended approval.
  2. Tip. The jar moves the USDT from the tipper to the recipient.
A BOT tip takes one transaction. USDT has 6 decimals, not 18. The tip page handles this for you. If you read tip amounts yourself, see USDT and decimals. Testnet USDT comes from the faucet. See Get testnet tokens.

​
After you deploy

The final step shows your tip link with a copy button. Open the jar’s Manage page for a QR code and the tips you’ve received.
