Digital asset infrastructure provider BlockFills has partnered with decentralised finance (DeFi) platform Definitive Finance, to enhance its on-chain trading capabilities for institutional and venture capital clients. The integration allows BlockFills to offer automated execution across a wider range of tokens, including less liquid and emerging assets, while improving execution quality and maintaining trading anonymity.
Definitive’s execution platform enables asset managers, hedge funds and VC firms to manage large positions in altcoins and other digital assets with minimal market impact. The system routes trades through aggregated liquidity across over 100 decentralised exchanges, liquidity pools and off-chain market makers on Solana and Ethereum Virtual Machine (EVM) compatible chains.“We’ve been seeing growing interest from firms looking to execute what I’d describe as non-trivial trade sizes in assets that are either difficult to trade, are challenging to custody, or that hold strategic significance, for example for venture capital firms who hold tokens from projects they’ve backed and want to exit those positions without causing disruption to the market or harming the charts of companies they support,” explains Patrick Zielbauer, Managing Director of Sales at BlockFills, in conversation with TradingTech Insight. “They need to get liquid, but they want to do it in a careful, discreet way. Essentially, we had clients who not only wanted to execute these types of trades, but also cared deeply about how we executed them. That demand prompted us to explore technologies that could support these needs. Definitive Finance emerged early in those conversations, so we began testing the platform, directing some initial flows through it. And so far, it’s been performing great.”
The partnership provides mutual benefits: BlockFills gains on-chain trade execution capabilities similar to its existing offerings in centralised finance (CeFi), while Definitive clients can access BlockFills’ over-the-counter liquidity, derivatives, and risk management tools. Advanced order types, such as time-weighted average price (TWAP), limit, and stop orders, are also now available through the low-latency platform.
“We’ve built infrastructure that connects to a wide range of on-chain venues, allowing clients to trade digital assets in an automated way using algorithms designed to minimise price impact and slippage,” comments Jai Prasad, Co-Founder of Definitive. “Until now, our primary users have been more crypto-native; funds and traders already active on decentralised exchanges but looking for more efficient execution. This partnership with BlockFills is particularly exciting because it opens the door to a much broader institutional audience, many of whom may not be deeply embedded in the crypto space but are increasingly seeking access to digital assets. We believe the BlockFills team is uniquely positioned to deliver that access in a secure, professional, and scalable way.”
Both firms anticipate introducing additional services through the collaboration, targeting a growing institutional demand for on-chain execution with institutional safeguards.
“Initially, we’ll continue directing trade flow through the Definitive Finance platform, with a focus on communication and education across both client bases,” says Zielbauer. “It’s about building mutual understanding, getting to know one another’s clients and identifying areas where we can add value for each other. Beyond that, we’ll begin exploring what a deeper, joint product development and integration might look like. BlockFills has a very robust technology stack, so I can envision a future where we’re fully leveraging every API endpoint Definitive makes available. That would represent a much more comprehensive integration, what I’d consider phase two.”
