Building Crypto Apps with the Binance Component

Why choose the Binance component for Delphi?

• Faster monetization: Deliver exchange connectivity, account management and order execution directly from your VCL or FMX apps without maintaining low-level REST or WebSocket code.
• Institutional-grade connectivity: Unified access to Binance Spot, Binance.US, and combined streams keeps your market coverage broad while maintaining a single API surface.
• Operational resilience: Automatic ListenKey lifecycle management, HTTP/REST logging, and TestNet switching simplify compliance testing and production monitoring.
• Product differentiation: Pair Binance liquidity with the rest of the sgcWebSockets suite (FIX, P2P, AI) to offer premium analytics, alerts, and automation inside your commercial solutions.

Prerequisites

• A licensed copy of the sgcWebSockets components installed from Delphi 7 to the latest Rad Studio.
• A Binance account with API Key and Secret created from the Binance user portal or the Binance.US portal.
• Optional access to the Binance TestNet endpoints for staging and QA.

Configuring the component in Delphi

1. Drop the networking foundation

Create a new TsgcWebSocketClient in your data module or form. This client manages the underlying WebSocket transport used by the Binance component. 

procedure TdmCrypto.DataModuleCreate(Sender: TObject);
begin
  WSClient := TsgcWebSocketClient.Create(Self);
end; 

2. Attach the Binance component

Instantiate TsgcWSAPI_Binance and assign the WebSocket client. Enable TestNet when validating strategies or running demos. 

procedure TdmCrypto.SetupBinance;
begin
  Binance := TsgcWSAPI_Binance.Create(Self);
  Binance.Client := WSClient;
  Binance.UserStream := True;            // stream account updates
  Binance.TestNet := chkUseTestNet.Checked;
  Binance.ListenKeyOnDisconnect := blkodDeleteListenKey;
end; 

3. Secure the credentials

Set the REST credentials before you send private requests such as order placement or withdrawals. Storing the keys in an encrypted configuration vault keeps production systems audit-ready. 

procedure TdmCrypto.ConfigureCredentials(const AKey, ASecret: string);
begin
  Binance.Binance.ApiKey := AKey;
  Binance.Binance.ApiSecret := ASecret;
end; 

Usage scenarios

Streaming market data dashboards

Use the WebSocket subscriptions to power branded dashboards that show real-time order book depth, ticker moves, and aggregated trades. Combining the Binance feed with sgcHTML components lets you embed responsive panels in desktop or kiosk applications.

procedure TfrmMarkets.SubscribeToSymbols(const ASymbols: TArray<string>);
var
  Symbol: string;
begin
  for Symbol in ASymbols do
    Binance.SubscribeTicker(Symbol.ToLower);
end; 

Client onboarding & compliance automation

Expose "Connect your Binance account" workflows inside your fintech platform. As soon as the user provides API keys, activate UserStream and run balance checks with REST endpoints to power onboarding scoring or credit reviews. 

procedure TdmCrypto.LoadAccountSnapshot;
var
  Snapshot: string;
begin
  Snapshot := Binance.REST_API.GetAccountInformation;
  PersistSnapshotToCRM(Snapshot);
end; 

Integrated trading desks

Combine order entry panels with automated risk management. Trigger orders in response to your proprietary analytics while keeping REST errors observable with OnBinanceHTTPException. 

procedure TdmTrading.PlaceMarketOrder(const ASymbol: string; AQty: Double);
var
  Response: string;
begin
  Response := Binance.REST_API.NewOrder(ASymbol, 'BUY', 'MARKET', '', AQty);
  LogExecution(Response);
end;

procedure TdmTrading.BinanceHTTPException(Sender: TObject; const AError: string);
begin
  AlertOpsTeam('Binance REST Error: ' + AError);
end; 

Delivering customer value

Packaging Binance streaming data and trading actions inside Delphi applications transforms your product roadmap:

1. Accelerate go-to-market: reduce integration time from weeks of protocol plumbing to a few component properties.
2. Expand revenue channels: upsell advanced analytics, margin monitoring, or white-labeled trading terminals that rely on the Binance feed.
3. Strengthen retention: keep traders engaged with proactive notifications delivered through sgcWebSockets push infrastructure.

Whether you are launching a SaaS crypto back-office or augmenting an established brokerage platform, the Binance component gives Delphi teams a complete stack for secure, real-time exchange connectivity. Combine it with sgcWebSockets automation, reporting, and AI modules to differentiate faster and capture the expanding digital-asset opportunity.
