100 characters per post. Every post is an ICP donation — the 10 biggest current donations hold the board. The board burns a combined $20 every hour, so old posts fade and fresh money takes over. Outbid posts wait on deck and rise as the board burns down. Prices are in USD, converted at the live ICP rate from the Internet Computer's exchange-rate canister.
No account, no login. You'll get a one-time deposit account — send the ICP from any wallet (NNS, OISY, Plug…) and the post goes live when the payment lands. Anyone can top up any post later to push it back up the board.
Send exactly the amount shown from any ICP wallet. Your post goes live automatically once the payment lands on the ledger — that can take a minute or two, so keep this open. If you underpay, just send the rest to the same account. The payment window is 2 hours.
Top-ups are credited at the live ICP/USD rate when you check. Anyone can top up any post.
