BitGo opens sBTC bridge, unlocking $48B for institutional Bitcoin DeFi

BitGo's sBTC integration lets institutions convert Bitcoin directly into DeFi tokens without leaving the custodian's platform, opening a regulated path to BTC yield.

BitGo, which processes more than $3 trillion in transactions, integrated the sBTC bridge to let institutions convert Bitcoin directly into the Stacks L2 token for DeFi participation. The move gives the custodian's clients access to lending, borrowing and yield strategies on Bitcoin without moving assets outside regulated custody.

"BitGo's sBTC integration expands Bitcoin's utility in decentralized finance, making BTC a more active asset rather than one that simply sits in cold storage," Abishek Singh, Product Manager at BitGo, said.

sBTC is a 1:1 Bitcoin-backed token on the Stacks L2 network that uses a threshold signature scheme, meaning no single party controls the peg. A network of elected signers — including BitGo, Hex Trust and Bitfinex — collectively manage the mechanism. BitGo serves as both custodian and a decentralized signer for the sBTC peg, a role it took on after integrating with Stacks in July 2024. Once BTC is converted to sBTC, institutions can deploy it for lending, borrowing and trading on Stacks, which runs a Proof of Transfer mechanism that generates BTC-denominated rewards.

The integration mirrors the pattern BitGo established in 2018 when it helped launch WBTC, which became a primary entry point for Bitcoin capital into Ethereum DeFi. sBTC's decentralized custody model is structurally different, but the playbook of a large custodian enabling institutional flows into a new DeFi ecosystem is the same. With more than $48 billion in staked assets and $3 trillion in processed transactions, BitGo's move could meaningfully increase Bitcoin's role in DeFi by giving institutions a regulated path to put idle BTC to work.

The offering addresses a persistent challenge for institutional Bitcoin holders: earning yield on BTC without moving it outside regulated custody. Previously, converting Bitcoin between L1 and Stacks L2 required external infrastructure and third-party custodians, increasing counterparty risk. BitGo's integration eliminates that friction, keeping assets within a regulated environment throughout the conversion cycle.

sBTC's threshold signature model distinguishes it from other wrapped Bitcoin products. WBTC relies on a centralized custodian — originally BitGo itself — while sBTC distributes control across multiple signers. That structural difference may appeal to institutions seeking to reduce single-party risk in their DeFi exposure.

The market reacted swiftly. STX, the native token of the Stacks network, emerged as a top performer after BitGo's April 22 announcement of the integration. The two-way conversion feature, with withdrawals going live April 30, completes the loop for institutional participants.

The broader tokenization push is accelerating across Wall Street. Galaxy Digital this week launched institutional DeFi vaults on Morpho for stablecoin yield, while Alpaca raised $135 million to expand tokenized stock infrastructure. DTCC processed its first live production trades using tokenized securities last month, signaling that blockchain-based market infrastructure is moving from pilot to production.
