Aptos Hosts $400M in BTC Assets as BTCfi Growth Accelerates with Key Integrations from OKX, Echo, and Aries

On June 4, Aptos confirmed a major milestone in its BTCfi ecosystem, now hosting nearly $400 million in BTC assets. This surge follows the integration of key protocols like Echo Protocol’s aBTC, OKX’s xBTC, Aries Markets’ WBTC, and Echelon Market’s SBTCZ. Aptos shared the growth details via X, highlighting the adoption of BTC-pegged tokens on the Move-based layer 1 chain. The expansion reflects the increasing interest in cross-chain Bitcoin assets, with major traction seen across DeFi platforms. 

BTC Assets Gain Momentum on Aptos Chain

Bitcoin on Aptos have surged to nearly $400 million, driven by strategic protocol launches. OKX’s xBTC, a 1:1 wrapped Bitcoin asset, recently saw a $30 million inflow. This inflow raised xBTC’s Aptos TVL to $40 million, integrating swiftly across top Aptos DeFi protocols. Echo Protocol dominates BTCfi on Aptos, managing nearly 70% of the BTC-pegged supply. With $878 million in Total Value Locked, Echo Protocol’s aBTC token leads BTC staking and yield operations. Echelon Market’s SBTCZ has secured $83 million in BTC assets, while Aries Markets’ WBTC holds $11 million. Aptos’ fast MoveVM architecture is positioning the chain as a high-efficiency environment for Bitcoin-backed DeFi assets.

BTCfi Sees Broader Ecosystem Expansion

The BTCfi ecosystem is expanding across various blockchains beyond Aptos. Lombard recently hit $2 billion in TVL, powered by its LBTC yield-generating asset. Despite the BOYCO incentive program ending, LBTC maintains relevance through platforms like Aave, which now holds 32% of all LBTC-based DeFi liquidity. Spark Finance also saw inflows, including a recent deposit of 250 LBTC, signaling active user diversification. While Ethereum hosts most LBTC liquidity, Base and Sui are slowly gaining share. Berachain recorded a minor decline, although Lombard still dominates with nearly half of the LBTC sector’s restaked TVL.

cbBTC Surges Past $4.5B in Circulation

Seoul Data Labs’ cbBTC has grown rapidly since its launch in September 2024. There are now 43,000 cbBTC in circulation, valued at over $4.5 billion. Ethereum remains the primary host, holding 64.1% of the supply, followed by Base at 30.3%. A 4,000 cbBTC inflow into Morpho Blue contributed significantly to Base’s increase. On Ethereum, Aave v3 supports 12,000 cbBTC as collateral, resulting in a high per-address average of 0.658 cbBTC. Other networks like Solana and Arbitrum hold smaller portions of supply at 5.4% and 0.2%, respectively.

BOB Strengthens Position with $219M in BTC Assets

BOB (Build on Bitcoin), an OP Stack-based hybrid L2, continues to grow its BTC asset base. The network now holds $219 million in BTC, ranking 11th among L2s. Key BTC-pegged assets include uniBTC ($43 million), SolvBTC Babylon ($42.4 million), and WBTC ($33.8 million). BOB also maintains strong on-chain activity, logging 1.8 million transactions and 68,000 users over the past 30 days. Weekly metrics show 500,000 transactions and around 27,000 active users. BOB has reached 496,500 unique users since launch, narrowly missing the half-million mark.

BTCfi Trends Point Toward Multichain Integration

Aptos is playing a pivotal role in the expanding DeFi space, with multiple blockchains now building native BTCfi infrastructure. Aptos has positioned itself as a strong contender in this sector, offering a low-latency, developer-friendly platform for BTC deployment. Protocols like the Echo Protocol and OKX’s xBTC are accelerating BTCfi growth by offering high liquidity and easy access. Other ecosystems, such as Lombard, Base, and BOB, highlight the increasing fragmentation and adoption of Bitcoin across networks. The trend signals a clear move toward multichain integration of BTC assets. With growing user interest and infrastructure support, BTCfi appears set to become a dominant DeFi vertical in 2025.
