Bitget has partnered with Siebly.io to give developers faster, safer access to its trading ecosystem — integrating Siebly’s SDKs for two API generations and multiple product lines to cut the time and complexity of building crypto trading apps.
What’s new
- Siebly’s SDKs now support Bitget’s V3 Unified Trading Account API and V2 Classic API, offering ready-made JavaScript and TypeScript libraries.
- Developers get out-of-the-box access to spot, futures, copy trading, live market data and private account functions — plus the exchange’s WebSocket API for persistent, low-latency feeds instead of repeated HTTP polling.
- Security options in the toolkit include HMAC, RSA and Ed25519 authentication for signing requests to protected account endpoints.
Why it matters
The SDKs are aimed at teams building trading bots, automated strategies and market-data tools. By removing the need to implement every exchange connection from scratch, Bitget says the libraries reduce development time and surface for bugs and integration drift. Siebly designed the toolkit around a consistent structure it uses across supported exchanges, making it easier to move projects between venues without rebuilding integrations.
“Developers building automated trading systems need SDKs that are consistent, secure, and tested in production environments,” Siebly.io lead developer Tiago Siebler said. “By collaborating with Bitget, we are making it easier for developers to integrate with one of the industry’s leading trading ecosystems.”
Integration ties into Bitget’s UEX push
The V3 integration aligns with Bitget’s Unified Exchange (UEX) strategy, which consolidates multiple asset classes and products under one account architecture. CEO Gracy Chen framed the Siebly partnership as part of Bitget’s effort to “deliver a better trading experience for users and developers worldwide” and let builders “spend less time on integration and more time building strategies on Bitget.”
Context on Bitget’s expanding product stack
- In July Bitget launched a Cross-Asset Unified Account that places cryptocurrencies and tokenized U.S. equities inside one margin system. The offering supports more than 370 eligible assets, including about 100 tokenized U.S. equities (rTokens). Customers can use eligible stock tokens as margin for futures/margin trades and pledge rTokens as collateral for stablecoin loans.
- Bitget’s Stock+ (part of Stocks 2.0) lets eligible users buy real U.S. shares using crypto. Deposited crypto is converted into USDC before purchase; ownership is held via regulated brokers, so users can receive dividends and corporate adjustments. Trades follow U.S. pre-market, regular-session and after-hours schedules.
- The exchange also tested its unified model with a global UEX Futures League contest offering 240,000 USDT in prizes across two monthly rounds (crypto futures in June; CFDs in July). Top teams from each stage were set to advance to an invite-only UEX Global Alpha Tournament with live sessions for finalists.
Developer impact and rollout
Bitget hasn’t announced a specific launch target for apps built with the new SDKs, but the libraries already cover multiple live products. For developers, the Siebly integration provides standardized, secure building blocks to tap Bitget’s unified account features, market feeds and private trading APIs — accelerating bot development, strategy testing and cross-product integrations.
Bottom line: Bitget’s SDK tie-up with Siebly reduces integration friction and helps developers connect faster to a growing suite of unified trading and tokenized-equity services on the exchange.
