Interact with QR Coin auctions on Base. Use when the user wants to participate in qrcoin.fun QR code auctions — check auction status, view current bids, create new bids, or contribute to existing bids. QR Coin lets you bid to display URLs on QR codes; the highest bidder's URL gets encoded.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# QR Coin Auction Participate in [QR Coin](https://qrcoin.fun) 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) | Contract | Address | |----------|---------| | QR Auction | `0x7309779122069EFa06ef71a45AE0DB55A259A176` | | USDC | `0x833589fCD6eDb6E08f4c7c32D4f71b54bdA02913` | ## How It Works 1. Each auction runs for a fixed period (~24h) 2. Bidders submit URLs with USDC (6 decimals — 1 USDC = 1000000 units) 3. Creating a new bid costs ~11.11 USDC (createBidReserve) 4. Contributing to an existing bid costs ~1.00 USDC (contributeReserve) 5. Highest bid wins; winner's URL is encoded in the QR code 6. 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. ```bash curl -s -X POST https://mainnet.base.org \ -H "Content-Type: application/json" \ …

How to install
mdr add bankrbot/skills/qrcoin@sha256:2866b9092c54e96bThe line at the top of this page pins the label git:20260131.a5e4df5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
