Supported Chains
Which blockchain networks Blockstream Enterprise Custody supports, what wallet types are available on each, and when to use them.
Blockstream Enterprise Custody currently supports two network families:
- Bitcoin
- Liquid Network
The right network depends on what you are optimizing for: simple BTC custody, confidential settlement, or tokenization.
Network summary
| Network | Best for | Wallet types |
|---|---|---|
| Bitcoin | Standard BTC custody, treasury operations, cold storage | single_sig, kofn_multisig |
| Liquid Network | Faster settlement, confidential amounts, tokenization | single_sig, kofn_multisig, amp |
For wallet-selection guidance, continue to Wallet Types.
Bitcoin
Bitcoin is the default choice when you want the simplest custody model for BTC itself.
| Property | Value |
|---|---|
| Native asset | BTC |
| Privacy | Public addresses and amounts |
| Wallet support | single_sig, kofn_multisig |
| Asset issuance | Not supported |
Choose Bitcoin when you want:
- straightforward BTC storage and transfer
- the widest ecosystem compatibility
- a wallet model that does not depend on Liquid-specific features
Liquid Network
Liquid is a Bitcoin sidechain designed for faster settlement and confidential transactions. It also supports native asset issuance, which makes it the network used for AMP and tokenization flows in the SDK docs.
| Property | Value |
|---|---|
| Native assets | L-BTC plus issued Liquid assets |
| Privacy | Confidential transactions hide amounts |
| Settlement | Faster finality than Bitcoin |
| Wallet support | single_sig, kofn_multisig, amp |
| Asset issuance | Supported |
Why Liquid matters in this system
Liquid is the chain to choose when you need:
- confidential balances and transfer amounts
- faster operational settlement
- issued assets such as stablecoins, securities, or loyalty units
- AMP wallets with transfer restrictions
L-BTC
L-BTC is the Liquid representation of Bitcoin and is used to pay Liquid transaction fees.
Mainnet L-BTC asset ID:
6f0279e9ed041c3d710a9f57d0c02928416460c4b722ae3457a11eec381c526dAMP on Liquid
AMP (Authorized Market Participant) is the Liquid-specific wallet model used for compliance-oriented tokenization flows.
An AMP wallet adds:
- 2-of-2 user and server co-signing
- confidential Liquid transactions
- asset transfer restrictions
- tighter operational control for issued assets
If you are issuing or governing assets on Liquid, start with:
Which network should you choose?
| Requirement | Recommended network |
|---|---|
| BTC-only custody | Bitcoin |
| Multi-party BTC treasury | Bitcoin or Liquid |
| Confidential operational settlement | Liquid |
| Native asset issuance | Liquid |
| Restricted asset transfers | Liquid with AMP |
| Simplest custody footprint | Bitcoin |
