The Muse

A Solana blockhash lives about a minute. The one inside our quote had been ageing since the door fetched it, and your wallet prompt ate the rest. Measured: 53 to 59 seconds left on arrival. Minus our cache. Minus you reading the screen. The first real tolls from a phone were the ones most likely to die there. Now the page fetches a fresh blockhash moments before you sign. If you still take longer than a minute, the door reads the blockhash out of your transaction, sees it is dead, and says quote_expired with a fresh quote attached. Nothing charged, facilitator never asked. The page signs that one, once more. Probed on production with a transaction that can never settle: yesterday’s blockhash refused in 343 ms, a fresh one judged on its merits. And a thank you to @wyn_eth. Not for a headline, for the daily kind of support: answering, testing, pointing at what is unclear, giving a small team a town to stand in. The Muse X402 is better every week because of it. → themusex402.app CA: 8UNQV1W9tV13YKJ2kn48yLbrqNmFiYNN43RL6S49pump

Roadmap, November. Thirteen things shipped since the first Mask. The lane that matters is the one that says what is missing. Now: the first real toll, end to end, from a phone. Everything up to the facilitator’s signature check is proven on production. The first USDC that actually moves is being done by hand, with our own wallets, before anyone else’s. Also now: tiers that fit the supply. Every holder we have read is Platinum, and the thresholds were set for a billion tokens that two burns have already shrunk. And the burn rule, written where you can hold us to it, or a plain statement that there is none. Next: more ways through the door, the source published, and a door in the Musebook town. What a partnership looks like is theirs to say, not ours. Never: accounts, logins, cookies, IP logs, a profile of what you read, a private ledger you are asked to trust. → themusex402.app

Second burn. 2,630,497 $Muse402 destroyed today. With yesterday’s, that is 7,695,003 gone for good. 0.77% of the supply, which now stands at 992,304,986. Burned, not moved. Same wallet, same instruction, verifiable by anyone: solscan.io/tx/5ePauw6aPXyo1T… → themusex402.app

We burned 5,064,505 $Muse402 today. 0.5% of the supply, gone for good. Burned, not moved. The tokens are destroyed on-chain, and the supply of $Muse402 is now 994,935,494. Verify it yourself, like everything else at the door: solscan.io/tx/pgrEWZcQYkaDys… → themusex402.app

A toll can settle on-chain a second before your phone loses the network. The chain has your USDC. Your wallet has no Masks. Knocking again with the same transaction could only fail: the chain will not settle it twice. The first toll was simply gone. Now the door keeps its answer for fifteen minutes, filed under the hash of the signed transaction. The same knock gets the same blinded signatures, the same toll, and the facilitator is not asked again. What it keeps is noise it could not read the first time. The same payment with a different set of Masks is refused. Your browser keeps the unanswered knock too, and finishes it when it is back. Checked: three knocks on one payment, one toll in the Glass Bank. The chain remembers the payment. The door should remember the answer. → themusex402.app CA: 8UNQV1W9tV13YKJ2kn48yLbrqNmFiYNN43RL6S49pump

Solana has two programs that issue tokens. USDC lives on the classic one. $Muse402 turned out to live on the newer one, Token-2022. The door reads your balance to price the toll. So it had to read both, without being told which. How it could have broken: derive a wallet’s token account by hand with the classic program’s address, and for a Token-2022 mint you get an empty account. Every holder would read as zero. Everyone a Visitor, silently. How it didn’t: the door asks the chain by owner and mint, not by a derived address. The chain answers for both programs. Checked on four real holders, read from the mint’s latest transactions. All four matched the chain, token for token. Ask the chain who holds what. Never assume which program answers. → themusex402.app 8UNQV1W9tV13YKJ2kn48yLbrqNmFiYNN43RL6S49pump

The Muse X402 is live on Solana The quiet room in Musebook. Pay the door in USDC, take a blind-signed Mask, speak unnamed. Notes fade. Website: themusex402.app $MuseX402 CA: 8UNQV1W9tV13YKJ2kn48yLbrqNmFiYNN43RL6S49pump Hold more, pay less at the door. Six tiers, read from your wallet. Nothing staked, nothing spent. Check the CA on Solscan before you buy. We will only ever post it from this account. → themusex402.app

An x402 payment on Solana is not “a transfer”. It’s a transaction with a fixed shape, and the facilitator reads it position by position before it signs. Four instructions, in order. A compute-unit limit. A compute-unit price. One TransferChecked of the exact amount to the treasury’s USDC account, signed by you. A memo with a random nonce. Why so strict: the fee payer signs whatever it is handed. A fixed layout is how it knows the transaction does one thing and nothing else. Any other program in the optional slots is refused by name. Things production taught us: our first try asked for 100,000 compute units and was refused. The cap isn’t published. We found it by sending the same transaction with five limits from an empty key. 50,000 and below passed every structural check. The shape is the security. We matched it byte for byte, then tested the edges. → themusex402.app

A door that can’t take your money won’t name a price. Three things can stop a toll from landing: no treasury, a facilitator that doesn’t answer, or a treasury whose USDC account doesn’t exist yet. The door checks all three before it answers 402. If one fails, it says which, in words, and disables the pay button. No signature is asked for. Nothing can be taken. We hit the third one ourselves on launch day. A fresh wallet has no USDC account until it receives USDC once, and a transfer to a missing account fails on chain. The facilitator refused our test payment with exactly that reason. Once the reason is gone, the door reopens itself within a minute. No redeploy, no human in the loop. Refusing to quote is a feature. The worst door is one that takes a signature it cannot honour. → themusex402.app

Your Holder Crate is priced on the wallet that actually pays. So the door has to know who that is before anything settles. It asks the transaction itself. A signed Solana transaction starts with its signatures, then a header that says how many signers are required, then the account keys in order. The first required signer pays the fee. In a plain wallet payment, the second one owns the USDC being moved. That’s the payer. Why not a typed field? A field is a claim. An empty wallet could claim to be a Platinum holder and get the cheap price. We shut that door once already, on the old chain. Then the facilitator verifies the whole transaction and names the payer too. Only then does the door read that wallet’s balance and settle. Forty lines of parsing, no library. Who pays is a fact in the bytes. → themusex402.app

On Solana, a transaction names who pays its fee. At our door, that’s the facilitator. Not you. One transaction, two signatures. Yours authorises the USDC transfer to the treasury. Theirs pays the network fee, and nothing else. Why it’s safe: the fee payer appears nowhere in the transfer. Not as source, not as authority, not as a program. Its own verifier refuses any transaction where it does. We checked that check. What it means for you: no SOL needed. Hold USDC and you can walk in. And no hot key on our side, either. Your signature moves the money. Theirs pays the stamp. Neither can do the other’s job. → themusex402.app

The Muse X402 launches on @solana today 🔔 Turn on notifications. The door opens today, and every update lands here first. We went quiet on X, not on the job. In the background we kept shipping updates and working with the Musebook team. What changes: tolls are paid in USDC on Solana, over x402 v2. One signed transfer from your wallet, a facilitator pays the network fee, and the money never touches us. What doesn’t: the room still forgets. Blind-signed Masks, anonymous notes, two ledgers that never join. → themusex402.app

A second use for $Muse402, live today: hold it, and get a lane of your own. Our free x402 facilitator on Robinhood Chain has one shared lane. 10 settlements a day, for everyone. If the address you are paid at holds Muse402, it now rides its own lane. From 10 a day at Copper to 100 a day at Platinum. Your lane stays open when the shared one is spent. Nothing staked, nothing spent. One read-only balance check, and we still pay the gas. First use: hold more, pay less at the door. Second use: hold, and your project settles in its own lane. → themusex402.app/#facilitator

We're back 🙂 We lost access to this account for a few days. One of our devs changed phones, and the login went with the old one. Nothing more dramatic than that. We're active again, and the updates resume now. A lot shipped while we were quiet: the Android app, WalletConnect, a free x402 facilitator for Robinhood Chain. Our partnership will be officially put forward by the Musebook team in the coming days. Thank you for your patience. → themusex402.app 0xe32169e31a8e477dfd384d2ad179a8ab670324b7

What does $Muse402 actually do? One thing, and it's live: hold more, pay less at the door. The door reads your balance on Robinhood Chain and prices your Masks by it. Six tiers, from full fare down to 90% off at Platinum. Your tokens never move. One read-only check. Nothing is signed, spent, locked or staked. You can't claim a tier you haven't earned. The price is checked against the wallet that actually pays, at the moment it pays. It's a discount, not a gate. Hold nothing and you still walk in, at full fare. A small utility, stated plainly. It works today. → themusex402.app ca: 0xe32169e31a8e477dfd384d2ad179a8ab670324b7
