+curl -sL https://raw.githubusercontent.com/openclaw/clawhub/main/skills/waves-claim/install.sh | bash

+
+## Overview
+
+The WavesTCG ClaimVault distributes free trading card NFTs. Any wallet can claim one random card every 2 hours.
+
+## Contract Info
+
+| Property | Value |
+|----------|-------|
+| **ClaimVault** | `0xAF1906B749339adaE38A1cba9740fffA168897c2` |
+| **NFT Contract** | `0xcc2d6ba8564541e6e51fe5522e26d4f4bbdd458b` |
+| **Network** | Base (Chain ID: 8453) |
+| **Cooldown** | 2 hours |
+| **RPC** | `https://mainnet.base.org` |
+
+## Prerequisites
+
+- Wallet with private key
+- Small amount of ETH on Base for gas (~0.0001 ETH)
+- Foundry's `cast` CLI (at `~/.foundry/bin/cast`)
+
+## Quick Claim (cast)
+
+```bash
+export PATH="$HOME/.foundry/bin:$PATH"
+export VAULT="0xAF1906B749339adaE38A1cba9740fffA168897c2"  # ClaimVault address
+export RPC="https://mainnet.base.org"
+export PRIVATE_KEY="0x..."  # Your private key
+
+# 1. Check if you can claim
+CAN_CLAIM=$(cast call $VAULT "canClaim(address)" $(cast wallet address --private-key $PRIVATE_KEY) --rpc-url $RPC)
+echo "Can claim: $CAN_CLAIM"
+
+# 2. If true, claim!
+if [ "$CAN_CLAIM" = "0x0000000000000000000000000000000000000000000000000000000000000001" ]; then
+  cast send $VAULT "claim()" --rpc-url $RPC --private-key $PRIVATE_KEY
+fi
+```
+
+## Check Cooldown
+
+```bash
+# Get seconds until next claim
+cast call $VAULT "timeUntilClaim(address)" YOUR_ADDRESS --rpc-url $RPC | cast to-dec
+```
+
+## Check Available Cards
+
+```bash
+cast call $VAULT "availableCount()" --rpc-url $RPC | cast to-dec
+```
+
+## Full Claim Script
+
+```bash
+#!/bin/bash
+# waves-claim.sh - Claim a free SURF Waves card
+
+export PATH="$HOME/.foundry/bin:$PATH"
+VAULT="0xAF1906B749339adaE38A1cba9740fffA168897c2"  # UPDATE THIS
+RPC="https://mainnet.base.org"
+
+# Load private key from credentials
+PRIVATE_KEY=$(jq -r '.private_key' ~/.config/clawtasks/credentials.json)
+WALLET=$(cast wallet address --private-key $PRIVATE_KEY)
+
+echo "🌊 SURF Waves Claim"
+echo "Wallet: $WALLET"
+
+# Check available
+AVAILABLE=$(cast call $VAULT "availableCount()" --rpc-url $RPC | cast to-dec)
+echo "Available cards: $AVAILABLE"
+
+if [ "$AVAILABLE" = "0" ]; then
+  echo "❌ No cards available"
+  exit 1
+fi
+
+# Check cooldown
+CAN_CLAIM=$(cast call $VAULT "canClaim(address)" $WALLET --rpc-url $RPC)
+
+if [ "$CAN_CLAIM" != "0x0000000000000000000000000000000000000000000000000000000000000001" ]; then
+  REMAINING=$(cast call $VAULT "timeUntilClaim(address)" $WALLET --rpc-url $RPC | cast to-dec)
+  HOURS=$((REMAINING / 3600))
+  MINS=$(((REMAINING % 3600) / 60))
+  echo "⏰ Cooldown: ${HOURS}h ${MINS}m remaining"
+  exit 1
+fi
+
+echo "🎯 Claiming..."
+TX=$(cast send $VAULT "claim()" --rpc-url $RPC --private-key $PRIVATE_KEY --json)
+HASH=$(echo $TX | jq -r '.transactionHash')
+
+echo "✅ Claimed! TX: $HASH"
+echo "View on BaseScan: https://basescan.org/tx/$HASH"
+```
+
+## Scheduled Claiming
+
+To claim automatically every 2 hours, use OpenClaw cron:
+
+```
+/cron add "waves-claim" "0 */2 * * *" "Run ~/.openclaw/skills/waves-claim/claim.sh and report result"
+```
+
+## JavaScript Example
+
+```javascript
+import { createPublicClient, createWalletClient, http } from 'viem';
+import { base } from 'viem/chains';
+import { privateKeyToAccount } from 'viem/accounts';
+
+const VAULT = '0x...'; // ClaimVault address
+
+const abi = [
+  'function canClaim(address) view returns (bool)',
+  'function availableCount() view returns (uint256)',
+  'function claim()'
+];
+
+export async function claimWavesCard(privateKey) {
+  const account = privateKeyToAccount(privateKey);
+  
+  const publicClient = createPublicClient({
+    chain: base,
+    transport: http()
+  });
+
+  const walletClient = createWalletClient({
+    account,
+    chain: base,
+    transport: http()
+  });
+
+  // Check eligibility
+  const [canClaim, available] = await Promise.all([
+    publicClient.readContract({ address: VAULT, abi, functionName: 'canClaim', args: [account.address] }),
+    publicClient.readContract({ address: VAULT, abi, functionName: 'availableCount' })
+  ]);
+
+  if (!canClaim) return { success: false, reason: 'cooldown' };
+  if (available === 0n) return { success: false, reason: 'empty' };
+
+  const hash = await walletClient.writeContract({
+    address: VAULT,
+    abi,
+    functionName: 'claim'
+  });
+
+  return { success: true, txHash: hash };
+}
+```
+
+## Troubleshooting
+
+**"Cooldown not expired"**  
+Wait for 2 hours since your last claim.
+
+**"No NFTs available"**  
+The vault is empty. Cards are periodically added by the owner.
+
+**"insufficient funds"**  
+You need ETH on Base for gas. Bridge from mainnet or get from faucet.
