Blockchain Application

Purpose

Guide smart contract development across all major blockchain platforms. Covers language selection, contract architecture, security patterns, gas optimization, deployment, and cross-contract communication. Platform-agnostic at the protocol layer; chain-specific at the language and VM layer.

Agent Protocol

Trigger

"smart contract", "solidity", "vyper", "evm", "rust smart contract", "solana contract", "anchor framework", "cardano", "plutus", "haskell contract", "cairo", "starknet", "sierra", "hardhat", "foundry", "truffle", "dapp backend", "contract deployment", "gas optimization", "contract security", "cross-contract call", "chainlink", "oracle contract", "defi contract", "nft contract", "move language", "sui contract", "aptos contract"

Input Context

• Target blockchain and VM type (EVM/SVM/eUTxO/StarkNet/MoveVM)
• Contract purpose (token/DeFi/NFT/oracle/governance/bridge)
• Upgradeability requirements (proxy/non-upgradeable/beacon)
• Security requirements (audit level, formal verification need)
• Performance constraints (gas budget, compute units, TPS needs)
• Existing dependencies (OpenZeppelin, Anchor libraries, Plutus contracts)
