BounceBit

BounceBit is a CeDeFi (Centralized-Enabled Decentralized Finance) infrastructure platform built on an EVM-compatible Proof-of-Stake Layer 1 blockchain. Launched on mainnet in May 2024 by Jack Lu — formerly a partner at NGC Ventures and co-founder of Bounce Finance — the platform was built to solve a longstanding problem in digital asset management: Bitcoin and other major cryptocurrencies have historically been dormant stores of value with no native yield mechanism. BounceBit addresses this by combining institutional custody standards with onchain settlement, giving holders of BTC, SOL, ETH, BNB, and stablecoins access to structured yield strategies previously available only to quantitative hedge funds.

How It Works

BounceBit separates three layers of asset management that are typically conflated in both traditional finance and DeFi:

Custody Layer: User assets are held with regulated custodians — CEFFU (Binance's institutional custody arm, secured with multi-party computation wallets) and Standard Chartered, a globally systemically important bank. Assets remain in segregated storage and never leave the custodian during yield execution.

Execution Layer: The primary yield mechanism is delta-neutral spot-perpetual arbitrage, executed via MirrorX — an off-exchange settlement technology that mirrors collateral from custody to trading venues like OKX without transferring ownership. A deposit of BTC, for example, simultaneously backs a long spot position and a short perpetual contract, capturing funding rate income with no directional market exposure. At a 0.03% daily funding rate, this approach can generate approximately 33% annualised returns.

Settlement Layer: BounceBit Chain records all positions, yields, and ownership onchain. When users deposit assets, they receive BB-Tokens — bridgeless ERC-4626-standard tokens representing their vault positions. BBUSD is backed 1:1 by USDT; BBTC is backed 1:1 by BTCB. These tokens rebase weekly to reflect accrued yield, so balances grow automatically over time and remain composable across DeFi applications without breaking yield accrual.

Key Products

CeDeFi Yield Portal is the primary interface for retail users and supports three modes. Fixed Mode offers guaranteed rates on locked assets with 30-day terms and weekly settlement every Friday. Auto Mode delegates allocation to an AI-managed system that distributes capital across multiple quant strategies and adjusts dynamically based on market conditions. Manual Mode lets users select specific quant teams — including Pythagoras Investments and Higgs Capital — and build custom yield portfolios.

BounceBit Prime is an institutional platform requiring a minimum of $500,000 USDT to onboard. Prime connects tokenized real-world assets to onchain execution, with assets custodied at Standard Chartered and collateral mirrored to OKX. Integrated products include Franklin Templeton's Benji tokenized treasury fund (approximately $692 million AUM) and BlackRock's BUIDL token (via Securitize). This enables institutional clients to use tokenized Treasuries — typically yielding around 4.5% — as productive collateral for additional crypto yield strategies. Redemptions are processed weekly on Thursdays with T+11-15 day settlement.

BounceClub is an ecosystem of dApps built on BounceBit Chain, including a DEX, a derivatives market supporting stocks and indices with up to 200x leverage, a meme token launchpad, and an AI agent marketplace. Third-party developers can submit smart contracts as plugins under flexible commercial models.

Supported Assets

The CeDeFi Portal supports BTC, ETH, USDT, BNB, and SOL, with accessible minimum subscriptions: 0.02 BTC, 0.5 ETH, 500 USDT, 1 BNB, or 5 SOL. On the real-world asset side, supported instruments include Franklin Templeton's Benji, BlackRock's BUIDL, Ondo Finance's USDY, Hashnote's USYC, and Superstate's USCC.

Token Economics

The native BB token is staked by validators to secure the network and accrues transaction fee rewards, doubling as a governance instrument. Users who stake BB receive stBB — a liquid staking derivative minted through the Liquid Staking Module — which can be used freely across DeFi applications while continuing to earn validator commission rewards. BB has a circulating supply of approximately 410 million tokens as of mid-2026.

Security and Compliance

CEFFU uses MPC wallets and requires multi-party approval for all asset movements. Standard Chartered's involvement brings banking-grade counterparty standards. Elliptic, a blockchain analytics provider, powers AML compliance with real-time risk scoring. Smart contracts implement the ERC-4626 tokenised vault standard. The MirrorX off-exchange settlement model eliminates exchange counterparty risk: underlying assets never leave the custodian.

Background and Funding

Jack Lu founded BounceBit in 2023 following six years as a partner at NGC Ventures. In early 2024, BounceBit raised $6 million in a seed round co-led by Blockchain Capital and Breyer Capital, with participation from Bankless Ventures, NGC Ventures, OKX Ventures, MEXC Ventures, HTX Ventures, and Nomad Capital. Binance Labs also backed the project. Key institutional partners include Franklin Templeton, BlackRock (via Securitize), Ondo Finance, Hashnote, Superstate, Google Cloud, and Ethena.
