⚙️ Integration Test Requirements

Integration tests require:

1. 🌐 RPC URL: Set ARBITRUM_ONE_RPC_URL in .env.test or use default public RPC
2. 💼 Test Wallet: For transaction tests, Anvil fork is recommended
3. 🔢 Block Number (optional): Set TEST_BLOCK_NUMBER for deterministic testing

Example .env.test:

ARBITRUM_ONE_RPC_URL=https://arb1.arbitrum.io/rpc
TEST_BLOCK_NUMBER=12345678
