Production-grade blockchain and Web3 development with Solidity (Ethereum/EVM), Rust (Solana), CosmWasm (Cosmos), including smart contract architecture, security patterns, gas optimization, testing strategies, DeFi protocols, and deployment workflows.

TL;DR

Production-grade blockchain and Web3 development with Solidity, Rust, and CosmWasm, including security, gas optimization, and multi-chain deployment.

What Is It

Smart contract development for Ethereum, Solana, and Cosmos
Security-first and gas-optimized contract design
Testing, deployment, and verification workflows
Upgradeable contracts and DeFi protocol implementation

Key Features

Security-first development with formal verification
Comprehensive testing: unit, fork, invariant
Gas optimization via Foundry snapshots
Multi-chain deployment and interoperability
Battle-tested DeFi patterns (AMM, lending, staking)
Upgradeable contracts (proxies, diamonds)
Cross-chain bridges and IBC interoperability
Backend crypto integration (C#, Kafka, CQRS)

How to Use

1.Identify blockchain platform (EVM, Solana, Cosmos, TON)
2.Choose appropriate framework (Foundry, Anchor, CosmWasm)
3.Implement secure, gas-optimized contracts with testing and audits
4.Deploy and verify on testnet/mainnet
5.Integrate with oracles, webhooks, and event-driven systems

Guardrails & Gotchas

MUST use security-first development
MUST avoid gas-inefficient patterns
FORBIDDEN: untested or unverified contracts
MUST validate signatures and webhooks
MUST use proven DeFi patterns (no reinventing AMM or lending)
