The blockchain infrastructure market split into two camps over the last five years.
On one side: Alchemy, QuickNode, Infura. Commodity JSON-RPC, indexed Data APIs, webhooks. Cheap, fast, undifferentiated. They compete on RPS and uptime SLAs.
On the other side: Chainalysis, TRM, Elliptic. Investigations, KYT, sanctions screening, FinCEN SAR support. Sold per-seat to compliance teams at $50K-$250K/year. Different sales motion, different buyer, different code.
Customers needed both, and got two contracts, two integrations, two bills.
What 1F is
A single API that does both jobs:
- Drop-in replacement for Alchemy/QuickNode —
POST /v2/{key}/{chain}proxies to upstream archive nodes with sub-1ms cache hits, plus indexed REST APIs for transfers, balances, holders. - Plus the compliance layer —
POST /api/forensics/screen,POST /api/kyc/screen, mixer correlation, multi-hop exposure, FinCEN SAR adapter, court-ready HMAC-signed reports. - Plus what neither side does: sub-millisecond cross-chain joins. Same EOA across 14 EVM chains plus Solana and Bitcoin in one query.
One API key. Three jobs done.
