81k works with founders and product teams to establish technical direction, build production-ready systems, and take products to market with professional execution where it matters most.
Application security review for highly sensitive, mission-critical systems operating in adversarial environments. Deep domain expertise in EVM smart contract security across complex pre- and post-deployment codebases. Extended to adjacent surfaces, including hardware security.
Engineering ownership from technical design through launch. Blockchain development expertise across EVM smart contracts, major integrations, and standards such as Chainlink.
Technical consulting for teams navigating and integrating transformative technologies such as AI. Clear judgement on technical direction, scope, and delivery while staying competitive as the landscape shifts.
81k supports clients by integrating closely with existing teams, contributing as an embedded partner, leading critical initiatives, and taking ownership of end-to-end delivery.
Technical product leadership and quality assurance for teams that need clear direction and alignment. We turn ambitious goals into scoped work and practical roadmaps, enabling engineering teams to execute with confidence.
Senior engineering support for protocol teams building smart contracts, integrations, and supporting infrastructure. We contribute directly across architecture, implementation, testing, and production readiness.
Security review for production systems operating in adversarial environments. We help teams identify critical risks early, harden architecture, review implementations, and continuously improve security posture as systems evolve.
Optimization for systems where cost, scale, and reliability matter. We improve critical paths and reduce bottlenecks, from gas efficiency in smart contracts to throughput and latency in supporting infrastructure.
