Chaincode Installer

WHAT IT DOES

Chaincode Installer enables developers to install and manage chaincode packages on blockchain networks. It reads and displays chaincode package status showing pending, installing, or installed states, installation transaction receipts with full details, gas estimates for the installation transaction, current gas price on the target network, chain ID for verification, account balance to ensure sufficient funds, nonce management for transaction ordering, deployed chaincode address once confirmed, installation logs showing detailed progress, chaincode verification status for package integrity, package metadata including name and version, chaincode version for upgrade management, channel information for targeting specific networks, endorsement policy for transaction validation, collection configuration for private data, instantiation status for chaincode lifecycle, approval status for governance, commit status for final deployment, chaincode definition with function signatures, package ID for identification, dependencies list for library management, source code references for audit trails, compilation artifacts for build verification, installation events for monitoring, and gas usage for cost tracking. The tool provides a streamlined installation interface with gas estimation and transaction signing, allowing developers to deploy chaincode packages to any EVM-compatible network with proper channel and policy configuration.

HOW TO USE

Connect your wallet to the tool and select the network where you want to install your chaincode. Enter your chaincode package in the text area (hex or base64 format). Configure the channel name, chaincode name, and version. Optionally provide an endorsement policy for transaction validation. Click "Estimate Installation" to get a cost estimate and verify the transaction will succeed. Review the estimated gas, gas price, and total cost displayed in the results section. Click "Install Chaincode" to sign and submit the installation transaction. The tool will show the transaction hash immediately, then update with the chaincode address and installation status once confirmed. The tool works with any EVM-compatible network that supports contract deployment via transaction data.

THE MECHANISM

Chaincode Installer uses the standard EVM contract deployment mechanism by sending a transaction with the chaincode package as the transaction data. The package is first validated and normalized to ensure it starts with the proper 0x prefix for hex format or decoded from base64 if provided. The tool estimates gas using ethers.js estimateGas method before installation to provide cost transparency and prevent failed transactions. Gas price is fetched from the network and updated in real time. The transaction is signed using the connected wallet's signer, which triggers the wallet interface for user approval. After submission, the tool monitors the transaction receipt using wait() to confirm installation completion. The installed chaincode address is extracted from the receipt's contractAddress field. Channel configuration, endorsement policies, and collection configurations are included as metadata in the transaction input. The tool also tracks package metadata including chaincode name, version, and package ID from the user inputs. All balance checks are performed using the provider's getBalance method, with results formatted in ETH.

WHAT IT CANNOT SEE

Chaincode Installer cannot verify that the chaincode package is correct or safe before installation, as it does not execute or validate the package contents. The tool cannot guarantee that the chaincode will execute as expected on all peers in the network, as execution depends on peer configuration and network state. It cannot detect if the installation will succeed on channels with different configurations, as channel settings may vary. The tool cannot predict exact gas costs for chaincode execution, as gas costs depend on the complexity of the chaincode functions. It cannot prove that the installed chaincode will behave as intended without additional testing and verification. The tool also cannot verify that the endorsement policy is correctly configured for the target network.

PLEASE NOTE

Chaincode Installer supports EVM-compatible chains only. Installation requires sufficient ETH or native token balance to cover gas costs. The tool does not store or transmit chaincode packages off-device — all processing is local. Some networks may require specific chaincode formats or policies — check your target network's documentation before installing. The tool is free to use and does not collect any data. Always test installations on test networks before mainnet.
