What blockchain platforms do your smart contracts support?
All EVM-compatible chains: Ethereum, Polygon, Arbitrum, Optimism, Base, BNB Chain, Avalanche, and any chain supporting the EVM. Non-EVM chains such as Solana and Cardano are scoped case by case, and we will tell you plainly when another team is the better fit. Miracuves deploys to the chain that fits your project - not the one we prefer.
How much does smart contract development cost at Miracuves?
A single contract starts from $3,699 and takes 3-8 weeks; the price stays fixed when your scope matches the base pattern. A protocol suite typically runs $8,000-$25,000 and takes 2-8 weeks; larger scopes are quoted in writing before work starts. Cost scales with the number of contracts (token, staking, governance), audit scope and firm selection, cross-chain deployment complexity, upgradeability requirements, and third-party integrations beyond the standard stack. Ongoing work is from $2,299/month for upgrades and monitoring. Every quote is written before payment, with no surprise invoices after kickoff.
Does Miracuves deliver the full smart contract source code?
Yes - completely. Miracuves delivers the full Solidity codebase, Hardhat/Foundry project with complete test suite, deployment scripts for all target chains, environment configuration, and audit reports. Zero lock-in. Your team or any other development firm can extend the contracts immediately after handoff.
How fast can a smart contract realistically be delivered and audited?
A single contract such as a token or NFT collection takes 3-8 weeks from brief to deployment, including the full test suite. Multi-contract protocol suites such as lending pools and DEXs take 2-8 weeks of build; larger scopes are quoted in writing before work starts. An independent audit usually adds 2-4 weeks, depending on the code size and the audit firm's schedule. All timelines are stated in writing before any payment is requested.
Solidity vs Rust for smart contracts - which does Miracuves recommend?
For most DeFi, NFT, and DAO projects, Solidity on EVM is right. Larger ecosystem, more auditors, cheaper development, and multi-chain deployment. Miracuves recommends Rust (Solana Native) honestly when your project needs high-frequency trading, very fast block times with low fees, or Solana-native features.
What security measures are included with every smart contract delivery?
Every contract includes: OpenZeppelin battle-tested base contracts, Slither static analysis, Foundry fuzz/invariant tests (95%+ branch coverage target), an independent audit before mainnet, and multi-sig admin controls. A contract does not go to mainnet until static analysis, the test suite and the audit are all cleared.
Does Miracuves handle multi-chain deployment and mainnet launch?
Yes, as part of every delivery engagement. Miracuves manages deployment scripts for all target chains, Infura/Alchemy node configuration, mainnet and testnet deployment, contract verification on block explorers, and post-deployment monitoring via Tenderly.
What happens after the smart contract is deployed if there are issues?
Every Miracuves delivery includes 60 days of dedicated platform guidance and 6 months of priority bug resolution. Bugs within the delivered scope are fixed at no additional cost; on-chain that means a reviewed proxy upgrade for upgradeable contracts, or a redeployment and migration plan for immutable ones. Gas optimization improvements beyond scope are quoted separately. Monthly maintenance retainers are available at published rates.
How does Miracuves handle NDA and IP for smart contract projects?
Miracuves signs a bilateral NDA before you share tokenomics, contract logic or launch plans - which matters on-chain, where a leaked mint or liquidity plan can be sniped by bots on launch day. The NDA covers all contract logic, business details, and proprietary algorithms. An IP assignment agreement transferring 100% ownership of the Solidity code, tests and deployment scripts to you is signed at project start - not at the end.
What does "community-audited" mean for a smart contract?
It usually means the code is public and has been reviewed by many independent people - through open source use, audit contests or bug bounties - rather than by one hired firm. The term fits widely used libraries such as OpenZeppelin Contracts. It does not cover your own custom logic: a token that imports an audited library is only as safe as the lines you added. For contracts that will hold user funds, Miracuves plans an independent audit of the custom code before mainnet and recommends a public bug bounty after launch.
Do you write custom smart contracts or only deploy templates?
Both, and we tell you which your project needs. Where a standard covers the job - an ERC-20, an ERC-721 collection, a multi-sig treasury - we build on OpenZeppelin library code and keep custom code to a minimum, because every custom line adds audit time and risk. Where the business rule is the product - staking rewards, vesting, escrow, lending or AMM logic - we write custom Solidity from your specification, with fuzz and invariant tests on each rule before it goes to audit.
Which smart contract development environment will our project use?
On EVM chains we work in Foundry for fuzz and invariant testing and use Hardhat where your team or existing scripts already rely on it, with a local node and a mainnet fork for realistic tests. Slither and Mythril run in CI on every pull request, and deployments are scripted rather than done by hand. The whole environment - tool versions, configuration, scripts and tests - is in the repository you receive, so any developer can rerun it.
