This article explains how to implement a CI/CD pipeline for Ethereum smart contract development using AWS services, covering architecture and workflow in Part 1 of a two-part series.

• CI/CD automates smart contract development, testing, and deployment across blockchain networks
• Uses Hyperledger Besu on Amazon ECS as development blockchain network for multi-developer integration
• AWS CodeCommit stores smart contract code; CodeBuild compiles and deploys contracts
• CodePipeline orchestrates workflow from code commit through testing to deployment
• AWS Secrets Manager securely stores HD wallet mnemonics for contract deployment
• Lambda functions updated with contract ABI and address after each deployment
• Manual approval gate between development (Besu) and testnet (Goerli) stages
• Amazon EFS stores Hyperledger Besu ledger database and configuration files

The pipeline addresses multi-developer challenges by providing centralized blockchain infrastructure and supporting different development frameworks like Truffle and Hardhat.
