Overview

Fintechs, wallets and corporate treasuries increasingly integrate DeFi — swaps, lending, yield, staking — into their offerings. We build integration layers with protocol risk assessment, allowlisted protocols, transaction simulation, position tracking, accounting data and controls such as limits and approvals, so DeFi can be used deliberately rather than ad hoc.

Common use cases

  • Wallet DeFi featuresSwaps and yield inside a wallet.
  • Fintech yield productDeFi yield via controlled integrations.
  • Treasury DeFiCorporate or DAO treasury strategies.
  • Exchange DeFi accessOffering DeFi products to exchange users.

Quick answers

DeFi Integration at a glance

The essentials in brief. Every project is scoped individually — ask us for specifics.

What is DeFi integration?
Integrate DeFi into fintech apps, treasuries and platforms — lending, swaps, yield and staking with controls.
Who is it for?
Typically Web3 startups, fintechs adding digital assets, and institutions exploring tokenization, stablecoins or on-chain settlement.
What does Shivacha provide?
  • Protocol due diligence
  • Allowlists
  • Simulation
  • Position tracking
  • Accounting data
  • Controls
Which technologies are used?
Solidity, Foundry, Chainlink, Blockchain Oracles, ERC-4626, Ethereum — chosen to fit your stack and constraints.
How does the process work?
Mechanism design → Risk modelling → Contract engineering → Off-chain systems → Launch.
What affects the cost?
  • Contract complexity and number of chains
  • Custody and wallet model
  • Independent audit scope
  • Indexing, analytics and back-office tooling
  • Compliance integrations (KYC, AML, Travel Rule)
  • Upgradeability and governance requirements
How long does it take?
A focused contract system or dApp MVP typically takes 8–14 weeks plus independent audit time; institutional platforms usually take 4–9 months.

Delivery

How an engagement runs

  1. 1

    Mechanism design

    Pricing, collateral, liquidation and incentive mechanics specified and simulated.

  2. 2

    Risk modelling

    Parameter selection with stress tests against historical and extreme scenarios.

  3. 3

    Contract engineering

    Audit-ready implementation with invariant and fork testing.

  4. 4

    Off-chain systems

    Keepers, liquidation bots, indexers and dashboards.

  5. 5

    Launch

    Guarded launch with caps, monitoring and staged parameter changes.

Security

Security built into delivery

Controls we apply by default on this kind of work — not a separate phase at the end.

Specification first

Roles, invariants and threat model documented before code.

Adversarial testing

Fuzz, invariant and fork tests plus static analysis on every change.

Key management

Admin keys in multisig or MPC with timelocks on sensitive actions.

Independent audit

Code prepared for — and we recommend — an external audit before mainnet value.

Dedicated team

DeFi Team

Mechanism designers and engineers for DeFi protocols and integrations.

FAQ

Frequently asked questions

Is integrating DeFi safe for a fintech?

It can be done responsibly with protocol due diligence, limits and monitoring; the product's regulatory treatment must be assessed separately.

Can DeFi positions be exited quickly?

It depends on liquidity and protocol mechanics; exit paths are assessed as part of due diligence.

Can you fork an existing protocol?

We can build on established open-source designs where licences allow, but forks inherit assumptions that may not fit your market. We review and adapt the mechanics rather than copying blindly.

Do you design token incentives for DeFi?

Yes, with an emphasis on sustainable, simulated incentive programs rather than short-term liquidity mining that leaves when rewards end.
