We build on-chain products
that ship to mainnet.
Crypto Indo Jogja is a blockchain development studio. We design, build, and audit smart contracts, dApps, and Web3 integrations for teams turning ideas into real products.
Full-cycle Web3 engineering
From contract architecture to the frontend users actually touch, we cover the whole path to production.
Smart Contract Development
Gas-optimized, test-covered Solidity contracts — tokens, vaults, staking, and custom protocol logic built for EVM chains.
dApp Engineering
End-to-end decentralized apps with modern frontends, wallet connection, and reliable on-chain/off-chain data flows.
Security & Review
Pre-deployment audits, fuzzing, and invariant testing to catch issues before they reach mainnet and your users' funds.
Web3 Integration
Bring on-chain features into existing products: payments, tokenization, indexing, and backend infrastructure.
A clear path from idea to mainnet
Short feedback loops, written specs, and nothing shipped without tests.
Scope
We map requirements, threat model, and the simplest architecture that works.
Build
Contracts and app built in tight iterations with tests at every step.
Review
Internal audit, fuzzing, and invariant checks before any deployment.
Ship
Deploy, verify, monitor, and support the product on live networks.
A focused team, based in Yogyakarta
Crypto Indo Jogja is an independent Web3 development studio. We work with founders and teams who need serious engineering behind their on-chain ideas, without the overhead of a large agency.
- ✓ Engineers who have shipped real contracts to production networks
- ✓ Security-first workflow — every release is tested and reviewed
- ✓ Direct communication, no layers between you and the people building
