Web3 Consulting
We provide blockchain consulting & development services based on years of delivering, improving and auditing web3 projects.
- Web3 is all we do.
- We hire only senior-level engineers. We intentionally keep our team small to focus on quality.
- We worked on projects collectively worth $650,000,000+.
- We primarily work with high-growth web3 startups valued at $50-$500 million USD.
- Example projects we've worked on: cross-chain bridges, blockchain indexing/monitoring solutions, RWA derivatives, L1 event systems, DeFi lending protocols.
Consult us to avoid costly mistakes and build a stellar product.

We're happy to say we've previously worked with:
Featured work
Dextrac
Dextrac is one of the first Chainlink node operators and a big player in the web3 infra space. PRISM is an indexing, monitoring & analytics solution for Chainlink nodes that processes millions of monthly Data Feeds and CCIP transactions, protocols which underpin a large portion of the DeFi world.
- Successfully migrated Node.js -> Go which resulted in the app showing real-time data at sub second page load times.
- Designed & built an architecture able to ingest and process a few million transactions per month staying up to date with current block finality times.

Toucan.earth
Toucan is a smart contract protocol which allows anyone to tokenize carbon credits, sell them on the open market, use them in a number of financial products and retire them. They've reached a peak of $120,000,000 TVL and tokenized 21,890,000 tons of carbon credits.
- built frontend & smart contracts for cross-chain bridges (Polygon to Celo and Regen) responsible for over $10,000,000 in safely bridged assets.
- built a Solidity & TypeScript SDK which facilitated the offsetting of tens of thousands of tons of CO2.
MultiversX
MultiversX is a distributed blockchain network with a peak TVL of over $130,000,000. It uses EGLD as its native token which has a limited max supply and has over 3,000 validators.
- We've worked on a Go L1 events system and a Rust DeFi lending protocol.
How much will it cost?
Every project involves unique technical challenges and unknown unknowns. At the start of a project, we know the least about it, so any estimates will be rough.
We bill by the week and always want the answer to "is Leet Software a great value" to be a resounding "YES!" We want you to stay with us because you like working with us, not because you're locked into some onerous contract.
We also love transparency, so our default rate is out in the open.
$7,000 USDC per week per dev
This rate is not set in stone and can change based on the project's complexity or timeline. But it serves as a starting point and guide. It helps you figure out if it makes sense to even talk with us. We believe that the value we provide is worth more than what we charge.
Ready to get started with us?
There's no perfect time to get started. Whether you have a formal proposal or a few napkin sketches, we're always happy to chat about your project at any stage of the process.
