What you can do on B² Network

  • Vault wallets

    Keys generated and sealed in the vault (AES-256-GCM, per-organization key), never shown.

  • MPC 2-of-2

    DKLs23 threshold ECDSA with your co-signer, which decodes every transaction itself before signing. The full key never exists.

  • Policies & approvals

    Per-transfer and daily caps, approval tiers, address book with cooldown, two-factor.

  • Send & receive

    Fees quoted and checked before signing, every transfer tracked to finality.

  • Wallet API

    One wallet per end user, idempotent transfers, signed webhooks.

  • Sanctions screening

    Destinations checked against the OFAC SDN list before every transfer.

  • Blockchain analytics

    Destinations risk-scored by your own Chainalysis, Elliptic or TRM Labs account; your policy blocks or asks for approval by risk.

  • Embedded wallets

    Wallets for your users, shared between their device and our vault; the device checks every transaction before signing.

  • Token issuance

    ERC-20 contracts deployed from the vault; mint and burn under approval.

  • DeFi apps

    Connect a vault wallet to dApps through WalletConnect, every request approved.
