## Questions

### Who runs investment and product decisions at BlockFills?

Co-founders Joseph Perry and Gordon Wallace set the strategic direction. Perry oversees platform architecture and digital-asset solutions, drawing on his experience building proprietary trading systems at Harmonic Solutions and Harmonic Dealings. Wallace brings sell-side trading and risk-management discipline from his tenure as Global Head of FX Trading at Deutsche Bank and head of global FX derivatives and proprietary trading at Credit Suisse.

### Is BlockFills a principal market-maker or an agency broker?

BlockFills operates an agency model. It executes on behalf of institutional clients against its aggregated liquidity pool and does not take proprietary positions against customer orders. The firm emphasizes anonymous order entry and execution, no last look, and no buy or sell size limits — architecture designed to prevent information leakage.

### Does BlockFills provide lending and derivatives, or only spot trading?

BlockFills covers spot, derivatives, and lending. Its derivatives suite includes futures, options, and perpetual swaps, restricted to Eligible Contract Participants in the US and Eligible Professional Clients elsewhere. The lending desk offers borrow facilities and yield-generating structures. OTC block trading and white-label SaaS tools round out the service set.

### Which client types does BlockFills serve, and are retail investors permitted?

BlockFills explicitly excludes retail investors. Its institutional client base includes miners, exchanges, funds, family offices, brokers, professional trading groups, payment processors, corporations, Web3 platforms, OTC desks, lending platforms, and high-net-worth individuals. All applicants must complete on-boarding as a legal entity or an individual professional account.
