CHAIN REACTION CAPITAL FUND 1
A Boston-based blockchain fund built on seven years of angel investing, sixteen portfolio companies, and an institutional process for selecting the next generation of infrastructure builders.
The institutions have arrived.
The infrastructure hasn't.
That's the opportunity.

02 THESIS
Capital is flowing in the rails underneath are still being built
Every major bank now has a digital-asset desk. Fewer than 1% of the tools they rely on have reached commercial maturity. Fund 1 backs the teams building the missing layer.
01
The institutions are already here
BlackRock, Fidelity, State Street, Goldman, Visa, JPMorgan — every major institution has shipped something on-chain in the last 24 months. Demand is no longer hypothetical.

02
The plumbing is still early
Custody. Compliance. Settlement. Identity. Data. The picks-and-shovels of institutional adoption are underbuilt — and that's where returns compound.
03
Pre-seed, before the market prices it in
$500K initial checks into 20 pre-seed positions. Board-observer seats. Concentrated enough to matter; diversified enough to catch winners.
