DePix is paid out on three networks: Liquid, Arkade and Spark. This page is the reference for how one is chosen, what each costs, and what does not change between them.
Liquid Network paused (security incident, 06/Sep/2026)Both flows on Liquid are disabled: Pix ➔ DePix (deposits) and DePix ➔ Pix (withdrawals). A POST /deposit with a Liquid address is refused with NETWORK_WALLET_UNAVAILABLE. Reference: 01a07718-e5dc-75fd-ad69-75cbd78071b7.
Arkade and Spark are in beta
Please do not use them in production yet, and do not test them with substantial amounts. We will announce here when they are ready for production use.
There is no parameter naming a network, by design. The payout address decides it: send the address in depixAddress on POST /deposit, and the DePix is paid on the network that address belongs to. Your configured default address, used when you send no depixAddress, is classified the same way.
An address on none of the three is refused when the QR is created, with DEPOSIT_ADDRESS_NETWORK_UNKNOWN and the message is not a Liquid, Arkade or Spark address. Nothing is ever assumed to be Liquid: the refusal comes before any Pix can be paid into the QR, not after.
On Spark there is no network fee on top: the network fee recorded on a Spark payout is zero. On Arkade there is a network fee of 330 satoshis per transaction, charged in addition to the cost per transaction — a payout and its split are two separate charges of it.
POST /withdraw converts DePix back to BRL, and it is processed exclusively on the Liquid network. Receiving DePix on Arkade or on Spark does not enable withdrawals on those networks: receiving and withdrawing are separate flows, and the withdrawal side follows Liquid. This is the standing rule, not a temporary state.While Liquid is paused, withdrawals are unavailable.
A split has to be on the same network as the payout#
When you send depixSplitAddress, it must be on the same network as depixAddress. A split on a different network is refused with SPLIT_ADDRESS_NETWORK_MISMATCH.
On Spark the token name does not identify the asset: any issuer can choose any name. DePix on Spark has a single official token identifier, and any other token presenting itself as DePix on Spark was not issued by Eulen. Verify the identifier before operating — always, not only during the beta.The identifier, the DePix/BTC liquidity pool that Eulen operates through the Flashnet AMM, and a swap example are in the Spark network guide.
Arkade addresses from the same wallet share their first half#
An Arkade address is 114 characters long and encodes two keys: the operator's and the holder's. Addresses issued through the same operator therefore begin with the same long run of characters, and differ only in the second half. Two addresses used in the same deposit — the payout and its split — were 114 characters each with the first 56 identical.Compare the whole address, never only its beginning. Two Arkade addresses that start alike are not the same address.
The payout or split address is on none of the three networks. Check for a truncated or mistyped address.
SPLIT_ADDRESS_NETWORK_MISMATCH
Both addresses are valid, but on different networks.
NETWORK_WALLET_UNAVAILABLE
The wallet of that address's network is not payable at that moment. Transient: retry later. Moving production traffic to a beta network is not the workaround.
INVALID_DEPOSIT_ADDRESS
The address has the shape of a supported network, but that network's wallet refused it.
INVALID_SPLIT_ADDRESS
The same, for depixSplitAddress.
All five are raised when the QR is created, before any Pix can be paid into it. See Message codes and Troubleshooting.
