“Gotta give a quick shout out to David for being one of the first academy students from start to finish to enter the Million Dollar Mint Club, breaking over 250 ETH minted in just the presale! He played a major role on the dev side and community building and management. The mint has gone super smooth.”

EVOL on Solana

Testimonial.to 9 March 2024

“We wanted a new website with the latest tech stack and design for our crypto project, EVOL on Solana. David’s team delivered it very quickly and with high quality. They worked hard, paid close attention to detail, and impressed us. Our users love the new website, and we will work with them again.”

Amir Diba

COO, Token Titans

Testimonial.to 6 March 2024

“Two words: great experience. Communication was strong, and we focused on solutions rather than problems. I’m part of Token Titans. We launched an NFT and got the whole job done in 48 hours. Nothing more to say — just great.”

The Ramen Shop NFT

Testimonial.to 3 January 2023

“They fixed our minting issues within an hour of us contacting them, even though our contract was already deployed and halfway minted.”

Paul Bhogal

Founder, Novus Lab

Testimonial.to 1 January 2023

“I met the Tokentech team about a year ago while we were working on the same project. Since then, we’ve recommended Tokentech to seven or eight projects. They are the only tech team I know with a 100% zero-error delivery rate. Beyond smart contracts for mints, we’ve created marketplaces and on-chain and off-chain tokens, and we will keep working with them on new products.”

Domingo Mattle

Founder, Not A Company

Testimonial.to 2022

“David always executes on the highest and most professional level. He helped us on multiple projects and always overdelivered. On our latest project, with 24 hours left, we called David and he did the impossible: a fully functional and flexible smart contract in 24 hours. The mint went smoothly and everything worked out perfectly.”

“David has extensive technical knowledge of Solidity and is also an experienced web developer. He puts a lot of effort and craft into his code, is very easy to work with, and is super well connected in the web3 community.”

Jordi

Developer, Nft2Print

Testimonial.to 2022

“We had a very complex smart contract conflict with our web3 application that we thought would take days to solve. David is a true lifesaver. He quickly identified the root of the conflict and found a solution. His knowledge of web3 smart contract technology was invaluable.”

01 / 05

Discord client note

Written recommendation

“David found a backdoor in the contract in less than five minutes. The function could have allowed ETH to bypass the initial investors’ repayment. He gave us clear instructions on what to do next. He saved us 50 ETH, along with a lot of potential legal fees. We are absolutely in his debt.”
