BroSettlement

Get started

BroSettlement

BroSettlement is API-first embedded MPC wallet, ledger, and settlement infrastructure for B2B products that need to create wallets for customers or business accounts, monitor deposits, control transaction signing, broadcast transactions, and reconcile on-chain activity.

It is designed to sit behind your own product experience, compliance stack, fiat partners, and business logic.

What BroSettlement provides

Embedded walletsCreate wallets or deposit addresses for users, merchants, sellers, recipients, players, or internal accounts.MPC signing controlUse DKG-generated, 2-of-3 MPC with a client-run Co-Signer and client-controlled signing policy.Transaction lifecycleMove from transaction intent to signing, broadcast, event delivery, and final reconciliation.Ledger recordsConnect deposits, withdrawals, and transfers to an append-only operating record.

Designed for

  • Stablecoin payment platforms that need wallets beneath their own payment UX.
  • Marketplaces and platforms that pay sellers, creators, vendors, or contractors.
  • Payroll, remittance, and disbursement products that need recipient wallets and payout records.
  • iGaming and betting operators that need fast deposit recognition and controlled withdrawals.
  • Mid-size exchanges and trading products that need wallet operations without a 100-chain enterprise program.
  • Fiat on/off-ramp providers that already own fiat rails and need the crypto wallet layer between fiat settlement and blockchain movement.

Product model

BroSettlement combines:

  • Embedded wallet provisioning for programmatic address creation.
  • DKG + MPC signing using a 2-of-3 threshold model.
  • Self-hosted Co-Signer so the client keeps a key share and policy control.
  • Transaction intents that separate product intent from signing and broadcast.
  • Blockchain gateway for deposit observation and transaction broadcast.
  • WebSocket lifecycle events for real-time operational visibility.
  • Append-only ledger for balances, transaction history, reconciliation, and audit evidence.
  • API security and RBAC with Ed25519 request signing, IP allowlists, nonce replay protection, key rotation, and owner/admin/operator/reader/service roles.

Product boundary

BroSettlement is

  • Infrastructure that sits behind your own product and user experience.
  • An embedded wallet layer for creating wallets and deposit addresses programmatically.
  • A DKG and MPC signing system using a 2-of-3 threshold model.
  • A noncustodial architecture where you run a Co-Signer, control a key share, and apply signing policy.
  • A wallet operations layer for deposits, withdrawals, transfers, network broadcast, transaction events, and reconciliation.
  • A ledger-first platform where the append-only journal is the operating record for balances and transaction history.
  • A B2B API product for technical teams.

BroSettlement is not

  • An OTC desk or crypto exchange.
  • A consumer wallet or front-end wallet onboarding product by itself.
  • A crypto checkout button or simple payment gateway.
  • A fiat acquiring, banking, SEPA, SWIFT, ACH, or card-processing rail.
  • A bundled KYC/KYB, AML, or Travel Rule provider.
  • A fully managed custodian that unilaterally controls client funds.
  • A guarantee that your company is licensed, compliant, or MiCA-ready.

When BroSettlement fits

BroSettlement fits when you need to:

  • Create wallets or deposit addresses for many users, merchants, sellers, recipients, players, or accounts.
  • Keep meaningful control over signing through a client-run Co-Signer.
  • Receive real-time transaction lifecycle events.
  • Reconcile product balances against on-chain movement through an append-only ledger.
  • Use wallet and settlement infrastructure beneath your own UX, fiat partners, compliance providers, and business logic.

When it may not fit

BroSettlement may not be the right fit if you only need:

  • A personal wallet.
  • Social login, passkeys, or wallet connectors.
  • A simple crypto checkout button.
  • Bundled fiat rails, banking accounts, card acquiring, KYC/KYB, AML, or Travel Rule automation.
  • A 100+ network enterprise custody suite.

Network coverage

BroSettlement is focused on stablecoin-relevant networks, including TRON and major EVM/non-EVM networks for practical USDT and USDC flows.
