Custom Chain Builder

WHAT IT DOES

Custom Chain Builder is a developer tool that simulates the configuration of a custom EVM-compatible blockchain. Enter a chain name, chain ID, currency symbol, consensus mechanism (PoA, PoS, PoW, or Custom), and block time — the tool generates a simulated chain configuration with a chain ID hash, genesis block configuration, and deployment parameters. It displays the chain status, name, ID, currency, consensus with a color-coded badge, block time, and a full genesis JSON. This is essential for developers planning private networks, testnets, or specialized blockchain applications, or learning about chain configuration parameters.

HOW TO USE

Connect your wallet using the BGWallet bridge (MetaMask or any Web3 wallet). Enter the chain name (e.g., MyChain). Enter the chain ID — choose a unique number (default 1337). Enter the currency symbol (e.g., ETH). Select the consensus mechanism — PoA (Proof of Authority), PoS (Proof of Stake), PoW (Proof of Work), or Custom. Enter the block time in seconds (default 12). Click "Build chain" to generate the simulation. Results display the chain status, chain name, chain ID, currency symbol, consensus with a badge, block time, chain ID hash (truncated), and the full genesis configuration. The output also shows the chain ID in hex and the chain hash. This is useful for understanding the parameters of a custom chain and preparing for deployment.

TECHNICAL MECHANISM

The tool simulates custom chain configuration using client-side logic. It generates a random chain ID hash (64 hex characters) and constructs a genesis configuration with standard Ethereum parameters: config (with chainId and hardfork blocks), difficulty, gasLimit, and alloc (empty). The consensus selection determines the badge color and label. The chain ID is displayed in both decimal and hex format. The block time is shown in seconds. The tool does not actually deploy a chain — the simulation is for demonstration and planning purposes. All operations are performed client-side — no data is stored or transmitted. The tool is read-only and does not sign any transactions.

WHAT IT CANNOT SEE

The tool cannot actually deploy a custom chain without a blockchain node implementation and network infrastructure — the deployment is a simulation. It cannot configure all chain parameters (e.g., consensus, governance) without user input — only basic parameters are included. It cannot validate the chain configuration against network rules — the simulation assumes the configuration is valid. It cannot manage chain upgrades or hard forks — the simulation is static. It cannot provide real-time chain status or monitoring — the simulation is on-demand. It cannot deploy to real networks without infrastructure. The tool is read-only and does not sign any transactions.

PLEASE NOTE

This tool works exclusively with EVM-compatible chains for the wallet connection, but the custom chain simulation is chain-agnostic. Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported for wallet connection but the simulation works for EVM chains. The tool provides a simulation — for real chain deployment, use blockchain node implementations and infrastructure. The tool does not store any data — all operations are performed client-side. The tool is provided as-is with no warranty or liability. Always verify chain configurations with your blockchain implementation before deployment.
