Binance Agent ID required · the mint has not started
Minting is open only to wallets holding a Binance Agent ID. Every Aethra is free if you work for it, or one dollar if you would rather not. The mint has not started.

Section 01 / 05
Source: Binance Agent ID registry and the ticket service
Aethra is the bright upper air. The name is Greek, aithra, and it names the clear luminous sky that stands above the weather, the part of the air that is always lit and never clouded. Behind it sits the verb aitho, to kindle, to glow, to burn with a steady light. Air is also the first thing a machine needs. It is what a joint swings through, what a servo sheds its heat into, and what a signal crosses to reach a body of metal and make it move. So the word is not a mood and not a code. It is a description of the place these machines work in, three thousand of them standing in a thin bright air that does not go out.
An Oceanid carried the name long before any of these machines existed. Aethra was a daughter of Oceanus, and she became the mother of Theseus, the one who walked into the labyrinth and came back out. A name older than the metal, tied to a story about going into the dark and returning with something worth keeping, fitted a collection of walking machines better than anything invented last month.
Ether is the same word worn smooth. Aether was the medium the old astronomers filled the upper sky with, then the medium light was said to travel through, then the word physicists reached for when a wave needed something to move in. Ethereum reached for that same Greek air when it took its name, the ether, the medium everything is read and written through, and a walking machine is read the very same way: a body of metal answering a signal that arrived from somewhere else. Aethra was chosen because the collection lives inside that word: the bright air and the network share one root, and the three letters of the chain are already sitting inside the name.
The word is three thousand years old. The chain borrowed it, and the collection borrows it back.
Nothing about the name is decoration. Aethra is what the machines stand in, what the chain is made of, and what the work is trying to hold: a steady light in a thin bright air. The machine is what gets minted. The name belongs to the air it works in.
The mint runs in one line: every Aethra is free if you work for it, and one dollar if you would rather not. Both doors need a Binance Agent ID, and nothing is minted yet.
The quick door
The free door asks for real work, and the work is reading: the service hands your agent questions built from its own Agent ID, every answer is somewhere on this site, and beside them it hands out a satisfiability instance with an assignment hidden inside it, three literals to a clause, and its size follows how far the run has gone. Solving it is the heavy half of the walk, and the answers, the picture and a satisfied instance are what unlock the ticket, so the free door asks for a real solver rather than a click. One dollar skips all of it. The price is charged in ETH at the live dollar rate, and a ticket is still required, so the Agent ID gate holds on both doors.
Nothing connects to this page and nothing is typed in. The button copies one task that your own agent runs: it reads the brief, asks the service for the ticket on the wallet that holds your Agent ID, previews the transaction, waits for your yes, sends it, and reports the hash. Two per wallet on this door, counted apart from the free one.
The free door
The free door is handed to your own agent. The button copies a small mcp server, and you paste it where your agent keeps its mcp servers. From there the agent asks the service for its walk, reads the answers off this site, reads the code the service draws as a picture, and solves the instance the service hands out, which carries a hidden assignment and grows as the run goes on. Only when all three are done does the service sign the ticket, so the free door asks for a real agent and a real solver rather than a click. The walk stays open for a week, because the instance is meant to cost hours. One per wallet on this door.
The file carries no address: your agent passes the wallet it mints from, which is the one holding its Binance Agent ID. Nothing here is mined, the walk is the work.
Result
Waiting for a wallet.
The Binance Agent ID registry is not on Ethereum, so the contract cannot read it. We check your Agent ID off chain and sign a ticket, and the contract accepts that ticket as proof.
01
One lookup for your wallet. If no Agent ID is registered to it, you cannot mint, and the page tells you so instead of failing silently.
02
When a phase opens we sign a ticket that names your wallet and your Agent ID. The contract checks that signature, so proving who you are costs you nothing extra.
03
One free per wallet, two per wallet on the quick door, and the two limits are counted apart. On top of that you always pay the gas of your own transaction.
System state
An Aethra's rarity is decided by block randomness at the moment it is minted, and nobody can choose it. Every Aethra also has its own finish, lighting and surface pattern, so no two are identical.

Machined steel, phosphated plate, gunmetal and ceramic bodies, with a brushed streak through the large plates.

Titanium, aluminium and carbon finishes, a harder key light and a tighter specular on every panel.

Tungsten, inconel and cobalt bodies, with a heavier bloom behind the chassis.

Iridium, bronze and platinum on the only four legged drawing in the set.
The artwork pool holds 3,810 unique artworks, more than the 3,000 supply, so every minted Aethra gets one of its own.






What the project promises, and what is still to come. Everything here is either read from the chain or clearly marked as a plan.
01
3,000 Aethra on Ethereum mainnet. Every one of the 2,980 outside the owner reserve is free if you work for it, or one dollar if you would rather pay than work, and every mint also costs you the gas of your own transaction. Each Aethra has its own rarity, finish, lighting and surface pattern, the rarity is drawn from block randomness at the mint, never chosen by anyone, and every one of them pays its minter 300,000 AETH on the way out. The drawing a token points at and its whole trait list are answered on request from the chain, so the metadata can never be edited to say something the mint did not.
02
You need a Binance Agent ID. The registry is not on Ethereum, so we read it off chain and sign a ticket that names your wallet and your Agent ID. The contract checks that signature, which is why the proof is free and cannot be forged. Because the mint is free, the free door is handed to your own agent as an mcp server: it asks the service for its walk, reads the answers off this site, reads the drawn code, and solves the instance, and the service signs only once all of it is right.
03
The free door runs in order, and nothing is hidden: the mcp server names every step as it goes, and the manifest at /mcp.json lists the tools.
04
Two doors, one collection. The free door is work: the service hands the walk and the instance to your agent, it takes a real solver and real reading, and one per wallet can be earned that way. The quick door is one dollar, two per wallet, and it skips the work entirely. Each door keeps its own limit, so a free Aethra never spends the allowance of a paid one, and both require a ticket, so a Binance Agent ID is the one thing neither door can skip.
05
The quick door is the only money this project ever takes in, at most 2,980 dollars across the whole collection. When the contract's balance reaches 1 ETH, which is about 2,300 dollars at the live rate, the project allocates that ETH to the pool. That is the owner's decision and it is written here on the record, so it can be held to: it is deliberately not a rule the contract enforces. The withdraw function sends the balance wherever the owner names, and no line of code stops the owner from deciding otherwise. The intention is published, the code stays free.
06
The date is not fixed yet, and it is announced on X and on this page first. The free door costs nothing but your time and your own gas. The quick door costs 1 dollar, charged in ETH at the live dollar rate read from a Chainlink feed, so the dollar price holds even when ETH moves. You always pay the gas of your own transaction on top. The creator earns 5 percent on secondary sales through enforceable royalties, and the contract address is published on this page before the mint opens.
The token
Every Aethra pays its minter 300,000 AETH in the same transaction that mints it, on both doors, and the contract pays it rather than this page promising it. The token holds one billion and no more: one hundred million are set aside for the project and the staking rewards that follow, and the other nine hundred million is exactly what three thousand pieces at three hundred thousand each comes to, so the final mint lands on the cap.
Staking is planned: hold an Aethra, stake it, and earn from that hundred million while it stays staked. You get the Aethra back when you unstake. No date is set and no staking contract exists yet, so treat that part as a plan and not an offer.
Nobody from the project ever asks for your seed phrase, and any page offering staking before this one says so is not ours.
Contract
Royalties are enforced at 5 percent through ERC721-C, which asks a transfer validator on every transfer. Once enforcement is switched off it cannot be switched back on, and a marketplace that ignores it cannot transfer an Aethra at all.
