The current Bsquared Network mainnet consists of two different chains. The parent chain is a fork of Ethermint. The rollup chain is a fork of of an Ethereum rollup stack.

TVL Data Coming Soon

We're currently gathering and building data infrastructure for this network. TVL analytics will be available soon.

Token Contracts

Token Contracts Coming Soon

We're working to collect the various BTC-backed token contracts for this network. Contract addresses will be available soon.

Risk Summary
Some contracts are upgradeable. These contracts may be related to BTC-backed tokens locked in the layer's official bridge contract.
A centralized party can immediately upgrade specific system contracts. This risk may be relevant to BTC-backed tokens locked in the layer's official bridge contract.
All BTC pegs have custodian trust assumptions
All BTC backing wrapped tokens on this network are ultimately secured by custodians. Users trust that these custodians will not misappropriate funds and keep their assets pegged 1:1. Each custodian has their own risks. Learn more in the trust assumptions review section.
Another data availability layer is used
Data related to the network's state is made available by an offchain committee. The network's state cannot make progress if this committee withholds the data. If the network cannot make progress, user funds can be frozen.
A centralized entity is the network operator
The network is operated by a centralized operator. If this operator goes offline, the network can be halted which can freeze user funds. Please see the trust assumptions to learn if their is a fallback mechanism for liveness failures.
Categorization
The project does not have an enshrined bitcoin bridge
The project does not have an enshrined bitcoin bridge that meets our sidesystem standards. Our standards require sidesystem's enshinred bridge programs to have at least 5 signers with 4 of those signers being external to the project's primary development organization.
Trust Assumption Review
BTC Custody
Very High
🛑
Users deposit funds into a MPC protocol managed by Bsquared Network and a custodian. Less than 5, individual signers have been publicly announced
Previous blog posts have stated that when users deposit funds into Bsquared, they deposit funds into a MPC wallet managed by the Bsquared Network team and Cobo, a institutional custodian. Information on how many signers participate in this MPC scheme is not available. Bsquared has stated that more players are being added into this custody scheme.
Data Availability
Very High
🛑
DA requirement is fulfilled by permissioned validators
Sequencer batches are posted to the Bsquared Network L1. This network consists of a permissioned validator set who is responsible for making the data readily available. The identities of these operators has not been disclosed.
Network Operators
Very High
🛑
Both the rollup chain and parent chain are run by federated, centralized parties
Bsquared Network’s implementation has a single sequencer that posts sequencer batches to its network of three L1 validators.
Finality Guarantees
Very High
🛑
Finality is guaranteed by a permissioned validator set
The network's state is updated offchain by nodes who apply state transition logic over the data made available by its data availability layer. After a new state is generated, a state root may be posted to bridge programs.
Bitcoin Security
Bsquared Network does not inherit any security from Bitcoin
In its current state, the network does not inherit security from Bitcoin.
The protocol does not enable MEV on Bitcoin. Users trust a centralized operator to not reorder their transactions.
The network does not introduce any MEV on the Bitcoin L1. Users trust the sequencer to not reorder their transactions to extract MEV.
An alternative token exists, but is not being used for network security
Network fees are paid in a BTC-backed asset on the network.
Bsquared Network does not contribute to the security budget
The network does not currently contribute to the Bitcoin security budget.
Technology
EVM-Compatible
Bsquared Network is EVM-compatible. The Ethereum Virtual Machine is software responsible for smart contract execution for a number of blockchains, namely the Ethereum Network. It uses Solidity/Vyper as its code and is the dominant environment for smart contract execution in the cryptocurrency ecosystem.
Use Cases
Onchain applications
Onchain applications are supported. Onchain applications including borrowing and lending protocols, onchain exchanges (commonly referred to as decentralized exchanges), and more. These applications are supported with more expressive smart contract environments.
