DeFi protocol engineering for production

Lending, yield, and collateral systems on EVM built with integrations, indexing, and operational reliability in mind. Smart contracts plus the backend and data pipelines required to run them safely.

What you get

Production DeFi protocols require more than smart contracts. We deliver end-to-end systems: protocol design, smart contracts, backend services, indexing, and operational support.

We build DeFi systems that hold up in production: contracts + the operational layer around them.

Protocol design & mechanics

+

Define lending/yield logic, collateral rules, liquidations, fees, and risk parameters. Output: spec that maps mechanics to contract modules and off-chain services.

Smart contracts (EVM)

+

Implementation, tests, upgrades, and deployment pipelines. Output: production-grade Solidity with clear upgrade and release strategy.

Backend services & integrations

+

Services that run protocol workflows and connect to your stack. Output: APIs, keepers/automation hooks, integration points, operational tooling.

Indexing & data pipelines

+

Operational data for monitoring, reporting, and downstream workflows. Output: indexers + pipelines that make protocol activity observable and usable.

Security-oriented development process

+

Threat modeling, invariants, test strategy, and staged releases. Output: pragmatic security discipline aligned with real delivery timelines.

Launch readiness & production support

+

Monitoring, incident playbooks, upgrade runbooks, and post-launch support. Output: operational readiness to protect funds and system integrity.

Core architecture

Smart contracts

+

Core protocol modules, permissions, upgrades.

Automation layer

+

Keepers, triggers, and safe execution hooks.

Backend services

+

APIs, ops workflows, admin tooling.

Indexing layer

+

Event indexing, analytics-ready datasets.

Ops layer

+

Monitoring, alerts, incident runbooks, release discipline.

What "production-grade" means

+

Clear invariants and failure handling. Observable systems: metrics, alerts, and debug paths. Safe upgrades: staged releases, rollback thinking, and runbooks. Operational tooling: the system is usable by real teams, not just deployable.

Common use cases

DeFi protocol scenarios where production infrastructure is essential.

Private credit / real-world yield protocols

+

DeFi mechanics integrated with real-world asset operations and reporting outputs.

Collateralized lending

+

Borrow/repay, interest accrual, liquidations, and risk controls built for maintainability.

Yield strategies and vault-like systems

+

Operationally safe strategy execution with monitoring and controlled upgrades.

Protocol migrations / upgrades

+

Refactors, upgrades, and rollout plans designed to minimize risk and downtime.
