Potato Tipper - OpenClaw Skill

Use this skill for anything technical around the Potato Tipper contracts repo:

• 📖 reading/understanding the Potato Tipper protocol
• ⚙️ setup + configure the Potato Tipper on your Universal Profile on LUKSO UP configuration
• ❓ permissions troubleshooting when setting up
• 💡building new tipping systems using ideas from the Potato Tipper

What it is (1-paragraph mental model)

The Potato Tipper protocol is an LSP1 Universal Receiver Delegate on LUKSO that automatically tips $POTATO tokens to new followers.

PotatoTipper is an LSP1 Universal Receiver Delegate that reacts to LSP26 follow/unfollow notifications and transfers LSP7 $POTATO tokens from the followed user's 🆙 to the new follower 🆙 (when eligible). Per-user settings live in ERC725Y storage under a dedicated data key, and the contract provides self-documenting helper views for config keys.

What this skill provides

• Understand architecture and LUKSO/LSP integrations (LSP1, LSP7, LSP26, ERC725Y) similar to the Potato Tipper
• Be aware of security and known limitations with this pattern
• Configure a Universal Profile with the required permissions and data keys
• Learn to build innovative integrations using the tip-on-follow pattern.
• Includes TypeScript (wagmi/viem/ethers + erc725.js) and Solidity code examples.

Quick workflows

1) Get oriented (repo map)

Read references/repo-overview.md for the file map + contract responsibilities.

2) Configure a user's 🆙 to use PotatoTipper (one-click)

This uses a Foundry script that performs the full setup in a single batchCalls transaction.

Step 1: Create the file script/SetupPotatoTipper.s.sol inside the Potato Tipper contracts repo:

}

interface ILSP7 {

        uint256 minFollowers = vm.envUint("MIN_FOLLOWERS");
        uint256 minPotatoBalance = vm.envUint("MIN_POTATO_BALANCE");
        uint256 tippingBudget = vm.envUint("TIPPING_BUDGET");

        console2.log("=== PotatoTipper Setup ===");
        console2.log("UP Address:", upAddress);
        console2.log("PotatoTipper:", potatoTipperAddress);

        dataKeys[1] = LSP1DELEGATE_ON_FOLLOW_DATA_KEY;

        bytes[] memory dataValues = new bytes[](3);

        vm.startBroadcast(vm.envUint("PRIVATE_KEY"));

        console2.log("Broadcasting batchCalls to UP...");

        console2.log("");
        console2.log("=== Setup Complete ===");
        console2.log("PotatoTipper is now connected to the UP!");
        console2.log("Settings configured:");

        console2.log("  - Min followers:", minFollowers);
        console2.log("  - Min POTATO balance:", minPotatoBalance, "wei");
        console2.log("Tipping budget authorized:", tippingBudget, "wei");
    }
}

Step 2: Run the setup via the shell wrapper:

TIP_AMOUNT=42000000000000000000 \
MIN_FOLLOWERS=5 \
MIN_POTATO_BALANCE=100000000000000000000 \
TIPPING_BUDGET=1000000000000000000000 \
PRIVATE_KEY=0x... \
./skills/potato-tipper/scripts/setup_potato_tipper.sh luksoTestnet 0xYourUPAddress

This single transaction:

• Connects LSP1 delegates (follow + unfollow)
• Sets tip settings
• Authorizes tipping budget

Manual setup details: references/config-and-data-keys.md Script implementation: references/foundry-batch-setup.md

5) Permissions (connect / disconnect)

• To connect: controller needs ADDUNIVERSALRECEIVERDELEGATE permission
• To disconnect: controller needs CHANGEUNIVERSALRECEIVERDELEGATE permission
• If setup fails with a permission error, this is the most likely cause

Full troubleshooting + UP Browser Extension steps: references/permissions.md

6) LSP1 implementation requirement

A smart contract MUST implement the LSP1UniversalReceiver interface (and report _INTERFACEID_LSP0 via ERC165) to be eligible to receive tips. The PotatoTipper checks supportsInterface(_INTERFACEID_LSP0) on the follower address and rejects EOAs.

When the $POTATO token transfer happens, it calls universalReceiver(...) on both sender and recipient 🆙. If the recipient contract does not implement LSP1, the transfer reverts (caught by the PotatoTipper's try/catch).

Code examples

TypeScript (wagmi / viem / ethers + erc725.js)

Full examples for encoding data keys, connecting/disconnecting from a dApp, and setting tip settings: → references/typescript-examples.md

Solidity

• Setting up PotatoTipper for a 🆙 from a smart contract
• Implementing LSP1 to receive tips in a custom contract
• Using loadTipSettingsRaw + decodeTipSettings free functions from any contract

→ references/solidity-examples.md

Guardrails / gotchas

• Only 🆙 (LSP0) followers are eligible (EOAs rejected).
• Follow/unfollow calls MUST come from the LSP26 Follower Registry — contract re-validates registry state.
• Uses try/catch around LSP7 transfers → returns user-friendly status messages, never reverts.
• "Existing followers" (before installation) are deliberately excluded from tips.
• Settings values (tipAmount, minimumPotatoBalance) are in wei (18 decimals).
