DeFi protocols engineered for bad days.
AMMs, lending markets, perpetuals, vaults and yield strategies, engineered with oracle safety, liquidation design, rate limits and governance that cannot be rushed.
[ 01 ]The short answer
What is DeFi Protocol Development?
DeFi protocol development is building financial primitives that run onchain: exchanges, lending markets, derivatives, vaults and yield strategies. The engineering problem is surviving adversarial conditions: manipulated oracles, cascading liquidations, flash loans, MEV and compromised admin keys. We model the economics, choose robust oracle designs, cap and rate-limit outflows, put collateral listings and parameter changes behind timelocks, and test with fuzzing and simulated market shocks before any capital arrives.
What you get
- Economic and risk model
- Contracts or programs with invariant tests
- Oracle and keeper infrastructure
- Simulation results under stress scenarios
- Launch plan with caps and monitoring
[ 02 ]What we build
The pieces, built to last.
- 01
Exchanges and AMMs
Constant-product, concentrated-liquidity and RFQ designs, with MEV protection for users.
- 02
Lending markets
Isolated or pooled markets with interest-rate models and liquidation engines.
- 03
Perpetuals and options
Margin, funding and risk engines with oracle and keeper infrastructure.
- 04
Vaults and strategies
ERC-4626 vaults with strategy limits, withdrawal queues and loss reporting.
- 05
Oracle design
Multiple sources, TWAPs, deviation checks and circuit breakers against manipulation.
- 06
Risk controls
Outflow rate limits, supply caps, pause guardians and timelocked parameter changes.
[ 03 ]Where it pays off
Where it earns its keep.
- 01
New protocol launches
From whitepaper to audited mainnet with staged caps.
- 02
Protocol forks done right
Forks with the original's lessons applied and its known issues fixed.
- 03
Institutional DeFi
Permissioned pools and vaults for regulated capital.
- 04
Treasury strategies
Onchain yield for company treasuries with strict risk limits.
[ 04 ]How we deliver
Four steps, one team, start to finish.
The same people scope it, build it and stay after launch. Timings are typical for a first release; we agree yours after the deep dive.
- 01Week 1
Threat model and spec
Who can move money, under what conditions, and what happens when a key, an oracle or a bridge fails. Written down before code.
- 02Weeks 2 to 8
Build with invariants
Contracts or programs with unit, fuzz and invariant tests, least-privilege roles, timelocks and rate limits from the first commit.
- 03Weeks 6 to 10
Review and testnet
Internal review, an independent audit where value is at stake, and a public testnet with monitoring wired in.
- 04Ongoing
Mainnet and watch
A staged launch with caps, live alerting on admin actions and outflows, and a rehearsed incident plan.

Problems we found, and how we would solve them.
- DeFi security3 min read
In 2026, DeFi lost more to keys than to code
ProblemMost stolen value now flows through compromised private keys, thin multisigs, single-verifier bridges and governance powers with no delay, which a code audit does not cover.ProposalAssume a key will be stolen: split and timelock admin powers, rate-limit outflows, delay collateral listings, require several independent verifiers, and wire monitoring that can pause before the treasury empties.Read the proposal - MEV3 min read
Sandwiched on Solana: protecting swaps from MEV
ProblemSandwich bots front-run and back-run user swaps on Solana through private order flow, and most protection today relies on users choosing a tight slippage setting they do not understand.ProposalProtect at the protocol and app layer: oracle-bounded minimum output, sensible default slippage computed per trade, bundled or private submission, and RFQ or batch execution for size.Read the proposal - Tokenization3 min read
Tokenized is not liquid: closing the RWA secondary-market gap
ProblemMost tokenized real-world assets only move through issuer mint and redemption; secondary trading is thin because transfer rules, slow settlement and missing integrations were never designed for it.ProposalDesign for liquidity from day one: portable onchain identity so approved holders can trade with each other, async redemption standards, an instant-redemption buffer, NAV oracles and pre-approved DeFi integrations.Read the proposal
[ 08 ]FAQ
Questions buyers ask.
In 2026, by value, compromised keys and governance shortcuts: Drift lost about $285 million after attackers took control of admin keys and listed fake collateral. By count, logic and oracle bugs. We design against both.
We model incentives and emissions as part of the protocol economics, and we will tell you when a token is not needed.
With minimum-output checks, oracle-bounded slippage, private or batched order flow and, where it fits, auction-based execution.
