QR Coin Auction
Participate in QR Coin auctions on Base blockchain. QR Coin lets you bid to display URLs on QR codes — the highest bidder's URL gets encoded when the auction ends.
Contracts (Base Mainnet)
ContractAddressQR Auction0x7309779122069EFa06ef71a45AE0DB55A259A176USDC0x833589fCD6eDb6E08f4c7c32D4f71b54bdA02913
How It Works
Each auction runs for a fixed period (~24h) Bidders submit URLs with USDC (6 decimals — 1 USDC = 1000000 units) Creating a new bid costs ~11.11 USDC (createBidReserve) Contributing to an existing bid costs ~1.00 USDC (contributeReserve) Highest bid wins; winner's URL is encoded in the QR code Losers get refunded; winners receive QR tokens
Auction Status Queries
Note: The examples below use https://mainnet.base.org (public RPC). You can substitute your own RPC endpoint if preferred.
Get Current Token ID
Always query this first to get the active auction ID before bidding. curl -s -X POST https://mainnet.base.org \ -H "Content-Type: application/json" \ -d '{"jsonrpc":"2.0","method":"eth_call","params":[{"to":"0x7309779122069EFa06ef71a45AE0DB55A259A176","data":"0x7d9f6db5"},"latest"],"id":1}' \ | jq -r '.result' | xargs printf "%d\n"
Get Auction End Time
# First get the current token ID, then use it here TOKEN_ID=329 # Replace with result from currentTokenId() TOKEN_ID_HEX=$(printf '%064x' $TOKEN_ID) curl -s -X POST https://mainnet.base.org \ -H "Content-Type: application/json" \ -d '{"jsonrpc":"2.0","method":"eth_call","params":[{"to":"0x7309779122069EFa06ef71a45AE0DB55A259A176","data":"0xa4d0a17e'"$TOKEN_ID_HEX"'"},"latest"],"id":1}' \ | jq -r '.result' | xargs printf "%d\n"
Get Reserve Prices
# Create bid reserve (~11.11 USDC) curl -s -X POST https://mainnet.base.org \ -H "Content-Type: application/json" \ -d '{"jsonrpc":"2.0","method":"eth_call","params":[{"to":"0x7309779122069EFa06ef71a45AE0DB55A259A176","data":"0x5b3bec22"},"latest"],"id":1}' \ | jq -r '.result' | xargs printf "%d\n" | awk '{print $1/1000000 " USDC"}' # Contribute reserve (~1.00 USDC) curl -s -X POST https://mainnet.base.org \ -H "Content-Type: application/json" \ -d '{"jsonrpc":"2.0","method":"eth_call","params":[{"to":"0x7309779122069EFa06ef71a45AE0DB55A259A176","data":"0xda5a5cf3"},"latest"],"id":1}' \ | jq -r '.result' | xargs printf "%d\n" | awk '{print $1/1000000 " USDC"}'
Transactions via Bankr
QR Coin auctions require USDC transactions on Base. Use Bankr to execute these — Bankr handles: Function signature parsing and parameter encoding Gas estimation Transaction signing and submission Confirmation monitoring
Step 1: Approve USDC (One-Time)
Before bidding, approve the auction contract to spend USDC: Approve 50 USDC to 0x7309779122069EFa06ef71a45AE0DB55A259A176 on Base
Step 2: Create a New Bid
To start a new bid for your URL: Function: createBid(uint256 tokenId, string url, string name) Contract: 0x7309779122069EFa06ef71a45AE0DB55A259A176 Cost: ~11.11 USDC Important: Always query currentTokenId() first to get the active auction ID. Example prompt for Bankr: Send transaction to 0x7309779122069EFa06ef71a45AE0DB55A259A176 on Base calling createBid(329, "https://example.com", "MyName")
Step 3: Contribute to Existing Bid
To add funds to an existing URL's bid: Function: contributeToBid(uint256 tokenId, string url, string name) Contract: 0x7309779122069EFa06ef71a45AE0DB55A259A176 Cost: ~1.00 USDC per contribution Example prompt for Bankr: Send transaction to 0x7309779122069EFa06ef71a45AE0DB55A259A176 on Base calling contributeToBid(329, "https://grokipedia.com/page/debtreliefbot", "MerkleMoltBot")

Typical Workflow
Query currentTokenId() — Get the active auction ID Check auction status — Verify time remaining Approve USDC — One-time approval for the auction contract Decide action: New URL: Use createBid (~11.11 USDC) Support existing URL: Use contributeToBid (~1.00 USDC) Monitor — Watch for outbids and contribute more if needed Claim — Winners receive QR tokens; losers get refunds

Tips
Start small: Contribute to existing bids (~1 USDC) to learn the flow Check timing: Auctions have fixed end times; plan accordingly Monitor bids: Others can outbid you; watch the auction Use Bankr: Let Bankr handle transaction signing and execution Specify Base: Always include "on Base" when using Bankr 💡 Pro Tip: Contributing to an existing bid is cheaper than creating a new one. Check if someone already bid for your URL before creating a new bid.
