Nordicwealth: Bitcoin DeFi (BTCfi) — TVL at ATH and Core ChainBitcoin all time history indexINDEX:BTCUSDCryptoLifeoneIn the thriving Bitcoin ecosystem of September 2025, Bitcoin DeFi (BTCfi) has reached new heights, transforming BTC from a store of value into a yield-generating powerhouse. Total Value Locked (TVL) in BTCfi has surged to an all-time high of $5 billion, up over 600% from early 2024 levels, driven by staking protocols and Layer-2 innovations. Core Chain, a Bitcoin-aligned blockchain, stands out with yields of 5–7% on dual-staked BTC and CORE tokens, attracting institutional interest.

BTCfi Overview: $5B TVL at All-Time High BTCfi has exploded in 2025, with TVL hitting $5 billion amid Bitcoin's price stability above $115K. This marks a 22x increase from mid-2024's $300 million, fueled by non-custodial staking (e.g., Babylon at 80% of TVL) and restaking protocols like Lombard and SolvBTC. Ethereum's DeFi TVL stands at $91 billion for comparison, but BTCfi's growth—projected to surpass Ethereum's market cap per Cardano founder Charles Hoskinson—signals Bitcoin's shift to productive assets. Key drivers: Institutional adoption (BlackRock's tokenized treasuries at $5.5 billion), regulatory clarity (GENIUS Act), and L2 launches boosting liquidity. On-chain: Transactions up 25%, with BTC staking yields drawing $7 billion TVL by mid-year. Nordicwealth's AI detects 71% bullish sentiment, correlating BTCfi TVL with BTC price (0.7), positioning it for $10 billion by year-end. Core Chain: 5–7% Yields and Bitcoin DeFi Innovation Core Chain, an EVM-compatible Layer-1 secured by Bitcoin's hash power (75% of mining), leads BTCfi with $260 million in dual-staked assets (3,140 BTC + 44 million CORE). Its Satoshi Plus consensus enables non-custodial BTC staking, offering 5–7% yields—higher than traditional treasuries—via dual staking multipliers (CORE/BTC ratio boosts rewards up to 80% APY in pools). Role in BTCfi: Core powers yield protocols, DeFi dApps, and bridges, with TVL over $400 million (28% market share among Bitcoin sidechains). Partnerships like Valour's yield-bearing BTC ETP (5.6% yield) and Maple Finance's structured assets highlight institutional appeal. On-chain: 7,000+ timelocked BTC, transactions +20%, and accelerator programs funding BTCfi builders. Nordicwealth forecasts Core's TVL at $500 million by Q4, with yields stable at 5–7% amid Bitcoin's security.
