About Token Terminal

Token Terminal is an institutional-grade data infrastructure and analytics provider for the blockchain economy. We extract, standardize, and deliver financial and alternative data on blockchains, decentralized applications, and tokenized assets to institutional and retail investors.

Our mission is to be the ground truth for blockchain data. We have over 120 blockchains indexed, manage over 4PB of data, and process over 200TB daily. We've implemented rigorous QA throughout the system to ensure we deliver the highest quality data. We've grown to serve over 50,000 monthly active users on our platform, while our API and data share power the most widely used TradFi and crypto platforms, including Bloomberg, Google, Binance, CoinGecko, CF Benchmarks, and Nansen. Through these partnerships, our data reaches tens of millions of users globally.

We are a remote-first company with employees distributed across the EU and US (East) time zones. We are headquartered in Finland, and our Nordic values are built into our culture: flat hierarchy, real ownership, and sustainable performance. As a small team, we're generalists who obsess over a high-quality product. We operate in a high-trust environment and default to action. We're looking for experienced engineers who can pick up new challenges and work together to solve them. We use TypeScript and SQL to build scalable systems and have a strong foundation that allows us to ship and prototype features quickly. We focus on industry-standard tools and prefer boring tech to keep our systems robust and scalable.

The Token Terminal Architecture

Our engineering team is split into three focus areas: Data ingestion and processing, analysis and serving. The Data team oversees managing the data ingestion from RPC nodes, loading and processing the data in BigQuery, and analyzing and calculating the project metrics for all projects listed. The Platform team focuses on our public API, main website: tokenterminal.com, and various integrations including our Google Sheets, Microsoft Excel and Bloomberg apps to name a few.

In all our processing, we strongly prefer ELT over ETL. Almost all data transformations on raw blockchain data are performed within our BigQuery data warehouse. This approach, coupled with the extensive use of SQL in our codebase, offers significant operational advantages. You'll encounter some elegant and innovative solutions especially within our SQL codebase.

While all of the data processing is done in BigQuery, we synchronize the resulting datasets into Clickhouse, that is the main source for API. This enables us to push our API to be faster and enable more custom and aggregations.

Over time, we've iteratively developed our proprietary blockchain data extraction framework. Our current, third-generation infrastructure is built in TypeScript and runs extraction jobs within Kubernetes.
