Bitcoin DeFi Protocol OP_NET Debuts 'SlowFi' Stack Eliminating Need for Bridges and Wrapped Tokens
OP_NET introduces a novel 'SlowFi' decentralized finance infrastructure operating smart contracts natively within Bitcoin transactions, utilizing only BTC for gas fees while eliminating reliance on bridges and wrapped Bitcoin tokens.
According to OP_NET, the project is rolling out a "SlowFi" decentralized finance (DeFi) infrastructure built directly on Bitcoin that leverages conventional Bitcoin transactions and native BTC transaction fees, completely bypassing the need for bridges, wrapped tokens or alternative gas currencies.
The project represents part of a wider initiative to enable trading and yield-generation activities natively on Bitcoin's foundational layer rather than channeling them through sidechains, cross-chain bridges or parallel network infrastructures, according to a Thursday announcement provided to Cointelegraph. The platform is wagering that certain users will tolerate slower processing speeds and higher transaction costs to maintain operations exclusively within Bitcoin's ecosystem.
OP_NET co-founder Frederic Fosco, who operates under the pseudonym Danny Plainview, explained that applications execute through conventional Bitcoin (BTC) transactions utilizing Taproot-based spending mechanisms, while the platform's NativeSwap architecture is engineered to facilitate token exchanges without requiring wrapped BTC or an independent gas token. In his conversation with Cointelegraph, Plainview emphasized that each transaction on OP_NET is "just a Bitcoin transaction with BTC as the only gas asset."
The platform's debut arrives amid an intensifying debate within the Bitcoin community regarding whether DeFi-oriented and data-intensive applications of block space bolster the network's fee marketplace or constitute spam that displaces monetary transfer operations.
Under typical fee market conditions, a swap transaction would generally cost approximately $1 to $2, while during periods of network congestion the cost could rise to roughly $10 to $20, Plainview noted, because users are only paying standard Bitcoin network fees instead of fees in a separate gas token.
The platform characterizes its approach as "SlowFi," maintaining that Bitcoin's approximately 10-minute block confirmation intervals and congestion-induced exit barriers can create stickier liquidity conditions and generate more sustainable DeFi market cycles compared to higher-speed blockchain networks.
Detractors claim OP_NET imports Ethereum-style DeFi complexity
In Plainview's view, implementing DeFi functionality on layer-1 provides a mechanism to sustain miner profitability as block subsidies continue diminishing over time, contending that "miners are bleeding" because of Bitcoin's programmed halving mechanism. "The only thing that keeps miners solvent is a fee market," he stated, emphasizing that OP_NET makes no modifications to Bitcoin's consensus protocol.
This perspective has attracted opposition from Bitcoin community members who contend that introducing DeFi-oriented activity onto the base layer dilutes Bitcoin's core monetary mission or saturates block space with non-critical transactions. Through recent social media posts on X, certain critics have characterized OP_NET as an effort to transplant Ethereum-style cryptocurrency infrastructure onto the Bitcoin network.
Certain Bitcoin maximalists have asserted that any efforts to broaden Bitcoin's functionality beyond its role as money transforms its advocates into "sh*tcoiners" larping as Bitcoiners.
In response, Plainview argued that any fee-compensated Taproot transaction ought to be recognized as a valid utilization of block space.
He cautioned that establishing ethical boundaries around transaction validity effectively grants de facto authority over Bitcoin to whichever entity determines those classifications. He said:
"The whole point is that nobody controls it."
OP_NET maintains DeFi operations on Bitcoin's base layer
The OP_NET platform joins a landscape already occupied by previous initiatives seeking to introduce programmability capabilities to Bitcoin, including solutions such as RSK and Stacks.
RSK functions as an independent Ethereum Virtual Machine-compatible sidechain employing its proprietary RBTC gas token alongside a federated BTC pegging mechanism, requiring users to transfer value away from the main network and place trust in a federation to oversee the bridging infrastructure.
Stacks, in comparison, represents a Bitcoin-anchored layer-2 solution with its native STX token and sBTC bridging system, processing smart contract operations on a separate blockchain that periodically settles to Bitcoin rather than executing within L1 transaction structures.
Through maintaining both execution and fee payment directly on Bitcoin while avoiding wrapped BTC or introducing new gas tokens, Plainview is making a calculated bet that a segment of users will willingly accept slower transaction processing and elevated costs in return for remaining exclusively on Bitcoin's foundational layer.
