Do you provide smart contract audit services for contracts you didn't write?

Yes. Third-party contracts go through the same pipeline as our own. That means automated static analysis and manual line-by-line review by a senior engineer. It also means exploit-class testing for reentrancy, overflow, access control, and oracle manipulation. You get a severity-ranked audit report with remediation guidance. You can publish it or submit it to exchanges and launchpads.

How long does smart contract development take?

A standard token contract (ERC-20/BEP-20/SPL) with audit ships in 2–3 weeks. Custom DeFi protocols, escrow systems, or RWA tokenization logic usually take 6–12 weeks. That depends on complexity and formal-verification scope. Audit-only engagements on existing code run 1–3 weeks, based on contract size.

How much does smart contract development cost?

Cost scales with logic complexity and audit depth. A standard audited token contract sits at the lower end. Custom DeFi protocols with formal verification are a larger engagement. We scope a fixed price after reviewing your requirements in a free consultation. No hourly open-ended billing.

FAQ

Frequently Asked Questions

Smart contract development is the design, coding, testing, and auditing of self-executing programs that run on a blockchain. It covers writing the contract logic (in Solidity, Rust, Vyper, or Move), hardening it against exploits like reentrancy and overflow, auditing it, and deploying it to a network. Elchai ships audited smart contracts for tokens, DeFi protocols, and RWA systems, typically in 2–12 weeks.

Smart contracts are self-executing programs stored on blockchain networks. They automatically enforce and execute agreement terms when predefined conditions are met. Traditional contracts need manual interpretation and enforcement. Smart contracts don't. They use code to encode business logic, trigger actions based on inputs, and record outcomes immutably on distributed ledgers. They also operate deterministically. Identical inputs always produce identical outputs, without requiring trust in any party.

Smart contracts run in blockchain execution environments. There, deployed code runs on thousands of nodes at once. When users or other contracts call a function, the nodes execute the code. They verify the transaction meets all conditions: sufficient gas fees, valid signatures, and correct parameters. If the conditions pass, they update the contract's state and record the transaction permanently on the blockchain. Oracles connect smart contracts to external data when needed. This lets them respond to real-world events.

Smart contract ownership depends on implementation design. Contracts can be ownerless and immutable once deployed. Then they execute only their programmed logic, with no administrative controls. Or developers can include ownership functions. These let designated addresses modify parameters, pause operations, or upgrade contract logic through proxy patterns. Best practice balances two things: security through minimal permissions, and operational flexibility like emergency controls and parameter tuning.

Solidity dominates Ethereum and EVM-compatible chains, thanks to its mature ecosystem and extensive tooling. Rust powers Solana, Polkadot, and NEAR programs with performance and safety guarantees. Vyper offers Python-like syntax for Ethereum. Its simplified features prioritize security audibility. Move brings resource-oriented programming to Aptos and Sui, with built-in safety properties. Go enables Hyperledger Fabric chaincode for enterprise blockchains. Cadence serves the Flow blockchain with resource-oriented design for NFTs. Language choice depends on three things: target blockchain, performance requirements, and available developer expertise.

Blockchain selection depends on your specific requirements. Ethereum offers maximum decentralization, liquidity, and composability. That makes it ideal for DeFi protocols that need trustlessness and interoperability with established protocols. Solana delivers extreme performance (65,000 TPS) at low cost. It's perfect for high-frequency applications like gaming and micropayments. Binance Smart Chain balances EVM compatibility with lower fees, which suits cost-sensitive DeFi projects. Hyperledger Fabric fits enterprise applications that need permissioned access and privacy. Polygon provides Ethereum scaling for applications that need lower costs while keeping Ethereum security. Our consultants help you weigh the trade-offs between decentralization, performance, cost, and ecosystem fit.
