Smart contract development services in Solidity
Smart contract development services produce the on-chain code that holds rules and value, so it has to be written carefully. Omeiro builds Solidity contracts for ERC-20 and ERC-721 tokens, optimises them for gas and tests them before any deployment.
Larger packages add a wallet-connect front end, IPFS storage and an internal security review before mainnet. This is engineering work, not investment advice.
Who commissions contract work
- Founders launching a token or NFT collection.
- Teams that need a dApp front end connected to wallets.
- Companies researching a web3 development company for a first project.
- Product owners wanting blockchain smart contract development or a solidity developer for hire.
What each contract package includes
- Basic: one ERC-20 or ERC-721 Solidity contract with tests and a testnet deploy.
- Standard: up to 3 gas-optimized contracts.
- Standard adds a wallet-connect dApp UI and source.
- Premium: a full dApp with IPFS storage.
- Premium includes an internal security review, mainnet deploy and 30 days of support.
How a contract goes from spec to chain
1
Write the spec
We pin down token rules, roles and what must never be possible.
2
Code and test
Contracts are written in Solidity with tests covering the edge cases.
3
Deploy to testnet
You try the contract on a test network before real funds are involved.
4
Review and go live
Premium adds an internal security review before the mainnet deploy.

What is included in the Basic Package?

Can I get a custom blockchain smart contract development package?
Yes. If none of the packages fits, use the custom package form on this page to describe what you need, and our team sends you a fixed price.
Is the internal security review the same as an audit?
No. It is our own review, and a third-party audit is a separate service you should consider for contracts that hold significant value.
Which chains do you deploy to?
The packages describe EVM-compatible deployment. Tell us your target chain before ordering.
Will I get the source code?
Standard and Premium include source.
What is gas optimisation?
It means writing contracts to use less computation, which lowers transaction fees for users.
