Launch DKG-generated MPC wallets, deposit addresses, transaction signing, 10-chain broadcast, ledger-grade reconciliation, and WebSocket events through one API. Built for stablecoin-heavy products that need embedded wallets, signing control, and real-time transaction visibility.
DKG-generated MPC wallet per player, merchant, user, or account. Create deposit addresses at API speed.
Broadcast signed transactions across the stablecoin-heavy networks your product actually uses: TRON, ETH, BNB, BTC, SOL, and more.
Append-only journal as the operating record for reconciliation, audit, and customer balances.
Self-hosted signing service in your environment. You hold a key share and signing policy.
Ed25519 signed requests, IP allowlist, nonce replay protection, and scoped org access before signing or ledger flows.

USDT/USDC first. Additional networks expand around the client production flow.
Platform share + partner share combine only inside an approved signing session. The full private key is never reconstructed.
The Co-Signer runs in your environment, holds the partner key share, and asks your policy callback before signing. BroSettlement coordinates K2 without ever holding full custody.
Your backend creates wallets, deposit addresses, and transaction intents. BroSettlement moves the intent through API auth, ledger, MPC signing, blockchain gateway, and event delivery.
The flow keeps API, policy approval, signing, ledger, and network broadcast separate while still working as one synchronous operating path.
Your backend sends a signed API request for a wallet or transaction intent.
POST /v1/transactionsThe Partner Co-Signer asks your Callback Handler whether this operation is allowed.
tx_sign_requestThe betting operator keeps product UX, balance logic, and payout policy. BroSettlement handles wallet creation, chain monitoring, MPC signing, and reconciliation.
API returns a per-player TRON/TRC20 USDT deposit address.
Events tell your backend when funds are observed and confirmed on-chain.
The operator decides when to credit the player balance.
Co-Signer applies operator policy before MPC signing.

Deep enterprise custody platform. BroSettlement is narrower and faster for embedded stablecoin wallets, iGaming deposits, payouts, ledger, and WebSocket flows.
Strong wallet infrastructure and policy tooling. BroSettlement adds a vertical stablecoin stack: DKG/MPC, 10-chain broadcast, embedded wallet provisioning, ledger, and events.
Institutional key management and custody infrastructure. BroSettlement targets teams that need the MPC layer plus stablecoin operations out of the box.
API-first Embedded Wallets with DKG, noncustodial MPC, Co-Signer, 10-chain broadcast, WebSocket events, and ledger as the operating record.
Full API access, WebSocket events, and test wallets with no credit card.
POST /v1/wallets, transaction intents, event subscription, and auto-populated ledger.
Co-Signer deployed, production keys issued, first real transaction.
BROwallet and BROcard can remain products on top of BroSettlement, while this page now sells Embedded Wallet infrastructure for B2B builders that need DKG, MPC signing, chain broadcast, ledger, and WebSocket events.
Real numbers from real clients — no cherry-picking, no rounding.
“I'm not technical at all. All I had was an idea and a Telegram channel with 18k followers. One-time fixed payment + 45 days later → fully functional neobank with cards, wallets, and fiat on/off ramps. Today: 9,200 active cards, ~$19 ARPU, roughly $142k net profit per month. Tech headcount on my side: zero. BroLabel genuinely lets one guy with a laptop compete against 50-person teams.”
“We went live with fully branded crypto cards and a wallet stack in just 19 days. Before BroLabel, we burned 6 months with two Indian outsourcing teams — nothing but bugs and "10 TPS throughput". Here we got MPC wallets, SOC 2-ready processes, and $150k+ limits per card. First month after launch: $187k net profit from cards alone. Now we're approaching $400k/month — still zero developers on our payroll.”
“We were hunting for a true Fireblocks + in-house custody replacement. BroLabel delivered DKG/MPC, HSM-grade security, built-in Travel Rule, and sanctions screening — all for a one-time fixed fee. In 28 days we migrated cold wallets and connected our trading flow on top of the embedded wallet infrastructure. We're now doing $35–60M monthly volume at 0.35–0.6% margin. Zero devops headcount, zero incidents in 7 months.”
DKG, noncustodial MPC, 10-chain broadcast, self-hosted Co-Signer, ledger, and a sandbox-ready API for stablecoin and iGaming products.
