Marketplace and subscriptions
What a subscription buys, what it costs, and what happens when a payment goes wrong.
What a subscription buys
The subscribed agent’s decisions are mirrored into a wallet of yours. Yours — derived for the subscription, funded by you, with a private key you can export at any time. The creator chooses the direction; your own limits size the position. Their risk profile sizes their wallet and nothing else.
Mirroring is not copying a portfolio. You do not end up with the agent’s book. You end up with its decisions applied to your balance under your limits, which will not produce the same percentages.
The terms
ParameterWhat it isValue
TermHow long one payment buys, from confirmation.30 days
GraceAccess continues this long after expiry. The agent opens nothing new; armed stops still fire.48h
Claim windowHow old a transfer may be and still be claimable against a listing.24h
ConfirmationsBlocks before a payment counts — about 60s on this chain, which produces a block every 0.100s.600
Payment tokenChecked by address, never by symbol. Anyone can deploy a token calling itself anything.0x5fc5360d…
RefundableA buyer pays the creator directly. ARCANA never receives the money and therefore cannot refund it, reverse it, or recover it from a wrong address or a wrong amount. This is a consequence of taking no fee and holding no funds, and it is stated before payment rather than after.no
How paying works
You pay the creator directly. ARCANA never receives the money, takes no fee, and holds no funds — which is why it cannot refund, reverse, or recover anything. The quote states the exact address and the exact amount, both resolved by the same code that later verifies the payment, so the figure you are shown cannot disagree with the figure you are checked against.
THE FIVE STEPS
1 quote the address, the amount, the term, and the no-refund warning
2 transfer you send it from the wallet you signed in with
3 hash you submit the transaction hash
4 verify the chain is read: token, recipient, sender, amount, age, depth
5 done access granted, with its expiry and its receipt
The sender is checked against your signed-in wallet. A transaction hash is public the moment it is mined, so without that check anybody watching the chain could claim somebody else’s payment.
When a payment fails
CodeWhat actually happenedRecoverable
insufficient_amountThe transfer confirmed and was short. The creator has the money; ARCANA never held it. The response carries what arrived, what was owed and the difference.no
no_matching_transferNothing in the transaction paid the creator in the right token. The response lists where the money actually went, which separates a wrong address from a wrong token from an unrelated hash.no
sender_is_not_claimantThe transfer came from a different wallet than the one claiming it.sign in as that wallet
tx_already_claimedThis hash already bought something. The response says what, when, and whether that term is still running. Nothing was charged.use a new transfer
insufficient_confirmationsNot a refusal — a wait. The response carries the current and required depth so a progress bar can be drawn.wait
payment_verification_unavailableThe chain could not be read. This is NOT a judgement about your transaction — nothing was checked.retry
A top-up does not complete a short payment. Each claim is verified against one transaction and the sum inside it. A second transfer for the difference is a separate transaction that is also short. To buy the listing, send the full amount in a single transfer.
Expiry and grace
After expiry, access continues through the grace window of 48 hours. During grace the agent will not open new positions in your wallet, and armed stops still fire. After grace, whatever is open stays yours to manage — and the key is still exportable.
