BlockFills and Definitive Finance Partner, Enhancing BlockFills Automated Trade Execution Capabilities for DeFi, On-Chain Transactions
Use of Definitive’s Trade Execution Platform Brings BlockFills Additional Order Flow from Asset Managers, Hedge Funds, VCs
CHICAGO and PUNTA PACIFICA, Panama, May 14, 2025 /PRNewswire/ — BlockFills, a premier destination for digital asset trading and market technology leveraged by institutions and professional traders, and Definitive Finance, a leading institutional-grade on-chain trading platform, announced that BlockFills has deployed Definitive’s advanced on-chain execution platform to enhance its automated trade execution capabilities on behalf of institutional and venture capital (VC) clients and expand the variety of tokens BlockFills can trade on behalf of its clients. The partnership brings new benefits to clients of both firms.
Patrick Zielbauer, Managing Director of Sales at BlockFills, said: “Definitive’s platform gives us an incredibly powerful tool to offer clients – including asset managers, hedge funds and VC firms – the ability to smoothly and efficiently enter or exit an altcoin position or token while protecting their anonymity and minimizing market impact. As a result of the partnership, we’re finding that even in the weeks since we deployed the platform, clients have brought more order flow to us, enabling them to take or exit from a significant position in even the most illiquid tokens, memecoins or other assets generally considered difficult to trade in nontrivial sizes.”
Jai Prasad, Co-Founder of Definitive, said: “Our secure, robust infrastructure was developed by our highly experienced team members who have a deep understanding of not only the digital asset market and DeFi world, but traditional finance, technology and the needs of the institutional investors BlockFills serves. Similar to what BlockFills does for clients in centralized finance (CeFi), our platform uses sophisticated trade algorithms that aggregate liquidity across liquidity pools on multiple chains and optimize trades to leverage the deepest liquidity, minimize price impact and achieve superior execution for on-chain transactions. While our platform is enhancing BlockFills’ capabilities offered to its clients, our clients and prospects that require access to deep OTC liquidity in the spot, derivatives* and lending markets can turn to BlockFills to augment and enhance their on-chain trading activities.”
Zielbauer said the Definitive interface is the best he’s seen for on-chain trading and DeFi. He anticipates BlockFills will bring additional offerings to the market through the partnership, further enhancing its appeal to a customer base focused on on-chain trading and simultaneously providing Definitive clients access to BlockFills’ robust suite of risk management products including options*, forwards* and perpetual swaps* for the digital asset markets. Definitive offers decentralized finance (DeFi) liquidity aggregation of more than 100 decentralized exchanges (DEXs), liquidity pools and off-chain primary market makers (PMMs)/dark pools across Solana and the Ethereum Virtual Machine (EVM) chains. An EVM is a decentralized computation engine that executes smart contracts on the Ethereum network. Advanced order types on the low-latency platform that are rarely seen in DeFi include time-weighted average price (TWAP), limit and stop order algorithms.
