Complete guide for integrating Arbitrum networks into your Bicrypto Ecosystem
This guide shows you how to integrate Arbitrum networks (Arbitrum Mainnet and Goerli) into your Bicrypto Ecosystem. You'll add Arbitrum credentials in .env, acquire API/RPC endpoints, then set up wallets and tokens in the admin panel—similar to how it's done for other EVM-compatible chains like Ethereum or Optimism.
Arbitrum Mainnet and Goerli Testnet are supported. ETH (Layer 2) is used for transaction fees on Arbitrum.
Add the following Arbitrum-specific variables to your .env file:
# Arbitrum Networks (mainnet, goerli)
ARBITRUM_EXPLORER_API_KEY="YOUR_ARBITRUM_EXPLORER_API_KEY" # e.g., 4EEJEPRYQG7D...
ARBITRUM_NETWORK="goerli"
ARBITRUM_MAINNET_RPC="https://YOUR_MAINNET_RPC_PLACEHOLDER"
ARBITRUM_MAINNET_RPC_WSS=""
ARBITRUM_GOERLI_RPC="https://YOUR_GOERLI_RPC_PLACEHOLDER"
ARBITRUM_GOERLI_RPC_WSS=""
• ARBITRUM_EXPLORER_API_KEY: Your Arbiscan API key for blockchain data
• ARBITRUM_NETWORK: Active network (mainnet or goerli)
• RPC/WSS URLs: HTTP and WebSocket endpoints for each network
Create an account at arbiscan.io and generate an API key for blockchain data access.
ARBITRUM_EXPLORER_API_KEY="your_key_here"
Sign up for RPC services like Alchemy, GetBlock, or others offering Arbitrum endpoints with reliable uptime and performance.
ARBITRUM_MAINNET_RPC="https://your-endpoint"
Some tokens don't support the PERMIT feature for fee delegation. For these tokens, you'll need to deploy custodial wallets.
Ensure your master wallet has sufficient ETH (Layer 2) to cover gas fees for custodial wallet deployments and transactions.
Go to Admin → Extensions → Ecosystem → Custodial Wallets and deploy a new custodial wallet for Arbitrum.
The platform will handle user deposits/withdrawals through this wallet, with the master wallet paying ETH gas fees.
Arbitrum gas fees are generally lower than Ethereum L1, but can still fluctuate. Monitor fees and adjust your minimum withdrawal fees accordingly.
Use Goerli testnet for development. Set ARBITRUM_NETWORK="goerli" and acquire test ETH from Goerli faucets.
