BaseZap makes it easy to reward builders, creators, or anyone who posts a helpful reply on Farcaster. You only need a username or cast link to send USDC directly to their wallet.

​
Two Ways to Tip

BaseZap gives you two flexible ways to identify a recipient. Both methods resolve to the same on-chain delivery — USDC sent directly to the recipient’s connected wallet on Base.

By Username

Enter the recipient’s Farcaster username (e.g., @alice). BaseZap automatically resolves the username to their verified wallet address — no copy-pasting addresses required.

By Cast Link

Paste the URL of any Farcaster cast. BaseZap reads the cast author and attributes the tip directly to them. Useful when you want to reward a specific post or reply.

​
Amount Presets and Custom Amounts

To keep tipping fast, BaseZap offers one-tap preset amounts. You can also enter any custom value. The fee preview updates in real time as you type a custom amount, so you always see exactly what the recipient will receive before you confirm. See Fees for a full breakdown.

​
How to Send a Tip

1

Open BaseZap

Launch BaseZap from within Farcaster or navigate directly to the mini app. Make sure your wallet is connected and you have USDC on Base Mainnet.
2

Choose your input method

Select By Username and type the recipient’s Farcaster handle (include the @), or select By Cast Link and paste the cast URL. BaseZap resolves the recipient automatically.
3

Select or enter an amount

Tap one of the preset amounts — 0.10,0.10, 0.50, 1,or1, or 5 — or type a custom USDC value in the input field.
4

Review the fee breakdown

Confirm the recipient’s display name, wallet address, tip amount, platform fee (2%), and estimated network cost. Everything is shown before you sign.
5

Confirm the transaction

Approve the transaction in your wallet. BaseZap submits it to Base Mainnet. Settlement typically completes in approximately 2 seconds.
6

See the confirmation

BaseZap shows a success screen with the transaction details. The tip has already landed in the recipient’s wallet.
Funds land instantly — no claiming, connecting, or extra steps are required by the recipient. As long as they have a verified wallet on Farcaster, the USDC arrives directly.
Transactions on Base are irreversible. Double-check the recipient’s username or cast link before confirming — BaseZap cannot reverse or recall a submitted tip.
