# DeFi Protocol Development

> DeFi development services: AMMs, lending, staking, and tokenomics engineered and simulated against adversarial market conditions before launch. By Sentient Arc.

Financial mechanism design on-chain: AMMs, lending, staking, and token economics modeled and stress-tested against adversarial market conditions while changing them is still cheap.

## The contract was fine. The incentives were not.
Most DeFi failures are not a Solidity bug; they are an economic one: an oracle that can be nudged, a pool that can be drained with a flash loan, an emission schedule that pays mercenaries to leave.

The mechanism is the product, and it has adversaries with capital and patience. A design that looks balanced on a whiteboard can unravel the first time a rational actor is paid to break it.

## Simulate the market before it is live
We design the mechanism as an economic system, not just code: incentives, invariants, and failure modes modeled explicitly, and stress-tested against the adversary who is trying to extract from it.

Oracles, liquidity, and parameters are chosen against simulated conditions, thin markets, price shocks, coordinated attacks, so the protocol behaves under stress the way it does in the pitch deck.

## What we build
- **AMMs & liquidity**: Swap and pool mechanics with slippage, fee, and impermanent-loss behavior modeled before they go live.
- **Lending, staking & yield**: Collateral, liquidation, and reward systems engineered so incentives stay aligned under market stress.
- **Tokenomics & vesting**: Supply, emissions, and vesting designed for durable incentives rather than a first-week mercenary spike.
- **Economic simulation**: Agent-based and scenario simulation of attacks and shocks, so parameters are chosen on evidence.

## Stack
- **Protocols:** AMMs, Lending, Staking, Yield
- **Economics:** Tokenomics, Oracles, Incentive design
- **Modeling:** Agent-based simulation, Scenario testing, Foundry

## FAQ
**What do your DeFi development services cover?**

Mechanism and token design, AMMs, lending, staking, and yield protocols, plus the economic simulation that stress-tests incentives and parameters against adversarial market conditions before launch.

**How is DeFi work different from smart contract development?**

Contract development makes the code correct; DeFi development makes the economics survivable. The hard problems are incentives, oracle safety, and market behavior, on top of a sound contract layer.

**Can you model tokenomics before we commit?**

Yes. Supply, emissions, and incentive simulation come before implementation, so the token design is tested against attacker and market scenarios while changing it is still cheap.

**Do you handle oracle and flash-loan risk?**

Directly. Oracle manipulation and flash-loan attacks are modeled as first-class threats in the design, and mitigations are chosen against simulated attacks rather than added after an incident.
