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.
The software-crypto-web3 skill provides developers with a comprehensive framework for building, testing, and deploying blockchain applications across multiple platforms. It addresses the challenges of creating secure, efficient, and scalable smart contracts by offering production-ready patterns for Solidity (Ethereum/EVM), Rust (Solana), CosmWasm (Cosmos), and TON contracts. The skill ensures developers can navigate complex blockchain ecosystems with best practices in security, gas optimization, testing, and deployment workflows, reducing the risk of vulnerabilities and improving reliability of decentralized applications (dApps).
This skill supports Ethereum/EVM (Solidity), Solana (Rust/Anchor), Cosmos (CosmWasm), and TON (Tact/FunC) smart contracts.
Yes, it provides guidance for unit, integration, fork, and invariant testing using Foundry, Hardhat, and Anchor, as well as static analysis and fuzzing with tools like Slither, Mythril, and Echidna.
Yes, it covers AMM, lending, staking, yield farming protocols, and token standards including ERC20, ERC721, ERC1155, SPL tokens, as well as DAO governance systems.
The skill includes mainnet/testnet deployment using Hardhat Deploy or Forge scripts, verification through Etherscan APIs, and upgradeable contract patterns with OpenZeppelin proxies.
Yes, it provides guidance on cross-chain interoperability, bridges, Cosmos IBC, multi-chain DeFi, and integration with Layer 2 scaling solutions like Arbitrum and Optimism.
