Hash until it looks back.
There is no mint button. Your GPU hashes until it finds a number that starts with 45 zero bits. The first wallet to get there mints the next Hashling, and the winning hash is drawn into its screen. Then the puzzle changes and everyone starts over.

How it works
Mine
Press start. Your GPU or CPU tries numbers, millions to billions a second, each mixed with your address and the last Hashling's hash. Nothing leaves your machine until one works.
Find
A hash with enough leading zeros claims the next Hashling at the epoch price. The moment anyone finds one, the puzzle changes and every search still running is void.
Reveal
Your Hashling shows itself one block later. Its face is drawn from a block hash nobody knew when you sent, so nobody can aim for a rare one.
Stake
Staked Hashlings share 65% of the ETH from every later mint. Lock one for 7, 14 or 30 days at 1×, 2× or 4× weight. No early exit.
Where the ETH goes
Every mint
- 65%Rent for staked Hashlings, split by weight
- 25%Buys $HASHLINGS and burns it
- 10%Builders
The buyback runs inside the mints. At most every 30 seconds, a mint spends the ETH set aside, buys $HASHLINGS and burns it. While no Hashling is staked, the stakers' share goes to the buyback too.
Price per epoch
Eleven epochs of 404 Hashlings, 4,444 in all. Each new epoch costs 0.002 ETH more and raises the minimum difficulty by one step.
Rarity
Only the rarest value of each trait glows. About 3 in 100 Hashlings have a glowing part. One has all seven.
Questions
What do I need?
A browser wallet with a little ETH on Robinhood Chain. When you connect, the page asks your wallet to switch to it.
Do I need a GPU?
No, but it helps a lot. Chrome and Edge let the page use your graphics card, which tries hundreds of times more hashes than a processor. Keep the tab open while you mine.
What does losing a race cost?
Nothing. The page checks every find before your wallet opens, so a beaten find is never sent. If two finds land in the same block, the later one reverts and costs a fraction of a cent.
How does the difficulty change?
The contract aims for one find every 10 seconds and adjusts after every 8 finds. Finds that come too fast make the next one harder, and so does one wallet winning several in a row, by 1.5× the work per step. If nobody finds one for 5 minutes, it gets twice as easy, and again every 5 minutes, down to the epoch's minimum.
What is drawn into the screen?
The hash that mined it: one bit per cell behind the face, lit faintly where the bit is 1. The blank rows at the top are the zeros it found. No two hashes are the same, so no two Hashlings are.
What is luck?
Every find needs a minimum number of zeros. Each extra zero is a coin flip the miner didn't have to win, and it's recorded with the Hashling forever. Eight or more extra zeros is Overdrive, and it glows.
What is $HASHLINGS?
The collection's token. Its whole supply launched on Pons before mining opened, with no allocation for anyone, the team included. A quarter of every mint buys $HASHLINGS and burns it.
What does the team get?
10% of every mint and the creator share of $HASHLINGS trading fees on Pons. No Hashlings are reserved and no $HASHLINGS were set aside. The contracts can't be upgraded or paused, and mining opens at a time published on chain, for everyone at once.
When does mining start?
At a time the contract announces at least an hour ahead. Once it comes, anyone can open the race, and the first puzzle is drawn from that block's hash.
