Look at the October 2026 numbers for Bitcoin DeFi: ~$4.4B in TVL—just 0.27% of Bitcoin's $1.65T market cap (Ethereum's chain TVL is ~11x larger). And almost all of that $4.4B sits in passive staking/restaking or wrapped tokens on other chains. What's missing? Native credit and options that settle on Bitcoin itself without giving up custody. That is why DIA's new integration with Arkade (@arkade_os) is such a big deal. ethereum:0x84ca8bc7997272c7cfb4d0cd3d55cd942b3c9419 delivers a cryptographically signed BTC/USD price feed that Arkade verifies directly for 3 native primitives: 1. Bitcoin-Backed Bonds: Margin calls and liquidations trigger at a signed price both borrower and lender can independently audit. 2. Cash-Settled Covered Calls: BTC owners write covered calls on locked BTC; expiry payouts in sats use multiple signed prints so a single bad quote can't skew settlement. 3. Solver RFQ Fills: Market makers quote from inventory and verify every fill against a signed reference. @DIAdata_org
