Goes furthest in Russia — 8 companies
This says who will engage, not what your scope should cost. A budget that reaches most of the market still buys very different things depending on what you are building.
Who is focused, and who has proved it
Horizontal: how concentrated a company is on Smart Contract. Vertical: how much checkable evidence stands behind it. 16 of 30 companies are plotted — the rest have fewer than 2 evidence signals, so placing them would be guesswork.

How a company is placed
- Focus is the inverse of how many categories a company claims, blended with the share of its portfolio tagged with this one. A firm listing three technologies is concentrated; a firm listing forty also appears here.
- Proven delivery adds published reviews (to 20), portfolio projects (to 25), Ahrefs Domain Rating (to 60) and years listed (to 10). Each is capped so no single signal carries a company to the top.
- Positions are relative to the other companies on this page: the median company sits at the centre of each axis, so a quadrant boundary means "ahead of half the companies listed here". Raw scores are in each bubble's tooltip.
- Deliberately excluded: the star rating, which sits in too narrow a band to separate anyone; the editorial rank, which is a hand-assigned sort weight; and paid verification, which does not move anything on this chart.
- Leaders:
- Concentrated on this work and with the record to show for it.
- Specialists:
- This is most of what they do, but the public evidence is still thin.
- Established generalists:
- A substantial track record, spread across many categories.
- Emerging:
- Building both focus and evidence.
Customer Reviews about Smart Contract
ENCYPHERS
The new email flows felt elevated, aligned with our brand identity, and created a more seamless experience for customers after subscribing and making a purchase. Communication throughout the project was organized and collaborative, and the final result added a much stronger retention layer to our ecommerce experience.
Webernetic
Команда Webernetic помогает нам c SEO-продвижением уже больше года. Когда мы обратились к ним, органический трафик нашего сайта был почти нулевым, но уже через месяца 2-3 начали приходить первые заявки. Команда оперативно погрузилась в наш проект и ни разу не подвела! Ребята не просто закрывали задачи по списку, а развивали наш сайт в долгосрочной перспективе. Коммуникация тоже была открытой, аккаунт-менеджер всегда был на связи и оперативно помогал со всеми вопросами. Смело можем рекомендовать Webernetic всем, кто хочешь улучить свой сайт)
PikArt
Работаем несколько месяцев. Что ценю больше всего не надо никого контролировать. Команда сама двигает проект, напоминает нам о съемках, согласованиях, дедлайнах. Отчеты понятные, без лишней воды. Видно прирост аудитории, вовлеченность, заявки. Если что-то проседает, они сами предлагают корректировки. Подключали блогеров, все прошло аккуратно и дало нормальный результат. По цене не самые дешевые, но по качеству сильно выше рынка. Однозначно рекомендую к сотрудничеству
