🧩 Making blockchain data sane with smarter tools

Syncs are slow, nodes unstable, and old node polling can’t keep up with fast chains.

Our latest blog dives into how indexing evolved and how modern tools like Substreams improve blockchain data processing.

While crypto payments are becoming baseline, checkout shouldn’t mean a rebuild.

In our new article, we show how to accept crypto with a modular, self-hosted setup that gives you 100% control:

• Works with custom checkout (no rebuild).
• Zero processor fees.
• Full custody, policy & funds control.

Just published a new case study on integrating new networks into a fiat onramp.

We added support for Solana, TON, Avalanche and Rootstock, implementing them within the client’s architecture with multiple abstraction layers to ensure secure and consistent transactions.

💡 Building an On-Chain Token Analytics – Case Study

We recently finished building a platform that tracks new token launches, buyer behaviour, and liquidity in real time across major DEXes and launchpads in Solana, Base, Ethereum, and BNB Chain.

Every token gets a profile with metadata, launchpad info, transaction details, and buyers previous activity. This makes it possible to spot coordinated buys and unusual early patterns almost instantly.

It wasn’t just about connecting to APIs. High-throughput chains and a continuously growing database meant we had to rethink how the system stores and processes data. We built a custom indexer and aggregation layer that turns raw on-chain events into structured signals.

Prediction markets like Polymarket rely on accurate outcome resolution.

We broke down how market resolution works with UMA Optimistic Oracle — from request → propose → dispute, how it’s backed by economic guarantees, and how it integrates in prediction markets.

Everyone’s talking about privacy

Our new deep dive breaks down how stealth addresses add a privacy layer to Ethereum transactions. We cover the core concepts, key standards, and how projects like Fluidkey and Umbra Cash implement them.

🔗 Read full breakdown here

Core Idea
Ethereum is built to be public. Every tx, balance change, contract call — everything is visible on-chain. Once an address is linked to you, your full on-chain activity is exposed.

Stealth addresses let users receive funds without revealing which addresses belong to them. Each transfer generates a one-time address that only the sender knows for that transaction, and only the recipient can find and spend from it.

How It Works
To receive funds via stealth addresses, you register a meta-address. This reveals that you can receive stealth payments, but only you can find the exact one-time addresses.

High-level flow:

1️⃣ Generate your spending key — your secret to access all future stealth payments.

2️⃣ Publish your meta-address — derived from your spending key; senders use it to create one-time addresses.

3️⃣ Sender generates a one-time address — each transfer gets a fresh destination using your meta-address + a random factor.

4️⃣ Funds are sent — transaction lands on the one-time address.

5️⃣ Detect & spend — you scan for incoming stealth payments and use your private spending key to claim them.

Standards to Know

ERC-5564 — stealth address announcements, view tags, and discovery logic

ERC-6538 — registry for meta-stealth addresses (sender lookup)

Exploring Privacy Stack in Anonymous Crypto Wallets

Privacy is a big narrative right now. Our team recently did deep research on how different crypto wallets handle anonymity, and we’re starting a series of posts to share what we found.

Today we’re diving into Cake Wallet — how it manages anonymity, the cryptography and network protections it uses, and the trade-offs involved in keeping transactions private.
