Smart Contract Development
Secure, production-ready smart contracts, tokens, and dApps — designed, built, and audited for the trust and ownership that Web3 demands, from testnet to mainnet.
Aetherian Intelligence provides end-to-end smart contract development for teams building on-chain. We design and ship audited, gas-efficient contracts and the decentralized applications around them — tokens, DeFi mechanisms, NFT systems, wallet flows, and on-chain infrastructure. Because smart contracts often control real value and can't be quietly patched after launch, we treat security as a first-class requirement, not an afterthought.
From a single token to a full protocol, we own the whole path: architecture, Solidity implementation, rigorous testing, review and hardening, and a staged deployment from testnet to mainnet — with the front-end dApp and integrations your users actually touch.
What our smart contract development services include
- Token contracts — ERC-20, ERC-721, ERC-1155 and custom standards, with minting, vesting, and royalties.
- DeFi & protocol logic — staking, swaps, vaults, and yield mechanisms designed for safety.
- dApps & decentralized front-ends — wallet connection, clear transaction UX, and live on-chain data.
- Wallet & account integrations — EVM wallets, account abstraction, and signing flows.
- Audits & security reviews — threat modelling, test coverage, gas optimisation, and hardening.
- On-chain data & integrations — indexers, oracles, and cross-contract logic.
Blockchains and stacks we work with
We build on Ethereum and EVM-compatible chains and Layer 2 rollups using Solidity, and on emerging ecosystems such as Sui — in fact we designed and shipped Netstream, a Web3 streaming app, on the Sui blockchain. We help you choose the chain that fits your users, transaction costs, and performance targets, rather than forcing your product onto one network.
Security and audits, built in — not bolted on
On-chain code is adversarial by default and frequently custodies real assets, so we harden it from day one. Every contract ships with a comprehensive test suite, threat modelling against known attack patterns, gas optimisation, and independent review. We deploy through public testnets with staged rollouts and add monitoring so issues surface early. The result is on-chain systems you can launch — and trust — with confidence.
Our process, from idea to mainnet
We Discover the mechanism, users, and risk model; Architect the contracts, data, and Web2/Web3 boundaries; Build in tight iterations with real tests and reviews; and Sustain what we ship — monitoring, maintaining, and evolving it as your protocol grows. You get production quality from the first commit, not a proof of concept.

Smart contract development — frequently asked questions
What is smart contract development?
Smart contract development is the design, coding, testing, and deployment of self-executing programs that run on a blockchain. These contracts power tokens, DeFi, NFTs, and dApps, enforcing rules and moving value on-chain without an intermediary.
Do you audit smart contracts?
Yes. Security is built into every engagement — threat modelling, comprehensive test suites, gas optimisation, and independent review. We also review and harden existing contracts before mainnet deployment.
Which blockchains do you support?
We build on Ethereum and EVM-compatible chains and Layer 2s using Solidity, as well as emerging ecosystems such as Sui — we built Netstream, a Web3 streaming app, on Sui. We help you choose the chain that fits your users, costs, and performance.
How much does smart contract development cost?
Cost depends on complexity — a single token contract is very different from a full DeFi protocol with audits. Email us with your scope and we'll provide an estimate.
How do you handle deployment from testnet to mainnet?
We deploy through testnets first, validate with automated tests and staged rollouts, and add monitoring so you launch to mainnet with confidence and can respond quickly if needed.
