Aptos Hosts $400 Million in BTC Assets Driven by Key Protocol Integrations

Aptos has achieved a significant milestone in its BTCfi ecosystem, now hosting nearly $400 million in BTC assets. This substantial growth is attributed to the integration of key protocols such as Echo Protocol’s aBTC, OKX’s xBTC, Aries Markets’ WBTC, and Echelon Market’s SBTCZ. The adoption of these BTC-pegged tokens on the Move-based layer 1 chain underscores the increasing interest in cross-chain Bitcoin assets, particularly within the DeFi platforms.

OKX’s xBTC, a 1:1 wrapped Bitcoin asset, has seen a notable inflow of $30 million, raising its Aptos Total Value Locked (TVL) to $40 million. This rapid integration across top Aptos DeFi protocols highlights the efficiency and appeal of the Aptos chain. Echo Protocol, which manages nearly 70% of the BTC-pegged supply, leads the BTC staking and yield operations with $878 million in TVL. Echelon Market’s SBTCZ has secured $83 million in BTC assets, while Aries Markets’ WBTC holds $11 million. The fast MoveVM architecture of Aptos is positioning the chain as a high-efficiency environment for Bitcoin-backed DeFi assets.

The BTCfi ecosystem is expanding beyond Aptos, with Lombard hitting $2 billion in TVL, driven by its LBTC yield-generating asset. Despite the end of the BOYCO incentive program, 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, indicating 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.

Seoul Data Labs’ cbBTC has grown rapidly since its launch in September 2024, with 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 (Build on Bitcoin), an OP Stack-based hybrid L2, continues to grow its BTC asset base, now holding $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.

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.
