A new protocol launching this week aims to finally bring actual decentralized finance directly onto Bitcoin’s base layer, allowing trading, token issuance, and other applications to run through standard Bitcoin transactions.

According to the project’s founders, the goal is to make Bitcoin itself the home for DeFi rather than routing liquidity through sidechains, bridges, or wrapped assets.

Chad Master, co-founder and chief business officer of OP_NET, told Decrypt that the team built the protocol around the idea that Bitcoin’s existing liquidity should remain on the network itself.



“We were seeing pitch decks for all these so‑called layer‑two solutions, and none of them were appealing to us as investors,” Master said. “When you really break it down, 99% of the solutions that have come across so far have been extractive to Bitcoin.”

The majority of so-called Bitcoin DeFi products require users to bridge their Bitcoin to another blockchain or wrap it into synthetic assets, such as the Ethereum-based Wrapped_BTC.

OP_NET claims to offer a different approach by embedding smart contract interactions into ordinary Bitcoin transactions confirmed by miners.

Smart contracts are self‑executing programs on a blockchain that automatically run when predefined conditions are met; they were popularized on Ethereum, whose network was built for complex programmable logic, whereas Bitcoin’s design focuses on simple, secure transactions, rather than general‑purpose applications.

“When we deploy a contract, we're using Bitcoin’s native scripting to generate a new address that holds the contract as the first transaction within that address,” Master explained. “Users, when interacting with that smart contract, send their contract call data through a Bitcoin transaction. The contract call data is embedded within the Bitcoin transaction.”

The protocol uses a network of nodes that scan Bitcoin blocks for contract-related data and execute the associated logic using a virtual machine environment. The resulting state is compared across nodes to maintain consensus while keeping transaction settlement on Bitcoin itself.

Danny Plainview, OP_NET’s co-founder and CEO, said the system builds on ideas that gained attention during the rise of Bitcoin Ordinals in 2023, when developers began experimenting with storing images, videos, and even video games inside Bitcoin transactions.

“In 2023, is when ordinals really started to take off,” Plainview told Decrypt. “When we dug into the tech, it became very clear that there is no gas token for this stuff—everything is paid in Bitcoin, everything is a Bitcoin transaction.”

Unlike Ordinals-based systems, which leverage Bitcoin’s SegWit and Taproot upgrades to place inscription data in transaction witness fields and rely on off‑chain indexers to track and interpret that data, Plainview explained, OP_NET introduces a consensus mechanism across nodes that track contract execution.

“What we created is that indexing—people call them meta protocols, but we like to call it a consensus protocol—because OP_Net is the first indexing protocol that has a consensus mechanism between the indexers that does not require a separate gas token,” he explained.

According to Plainview, expanding Bitcoin’s functionality is central to its long-term success.

“It's absolutely mind‑boggling to me that the culture in the Bitcoin space says Bitcoin is so great because it can only be used as money, but the chain isn’t scalable and not everyone can use it,” he said. “We think Bitcoiners should be allowed to do anything they want with it—if you can dream it, you can build it.”
