eth_getCode

Returns the bytecode at a given address on Boba Network.

Why Boba Network? Build on the Hybrid Compute L2 enabling smart contracts to access AI models and Web2 APIs natively with HybridCompute 2.0 for native AI/API access, $70M ecosystem funding, OP Stack compatibility, and two-way offchain integration.

Use Cases

The eth_getCode method is essential for:

• Contract verification - Check if address is a contract
• Security analysis - Verify deployed bytecode matches expected
• DeFi integrations - Validate contracts before interactions
• Protocol analysis - Analyze contract deployments for AI-powered dApps, Web2 API integration, enterprise blockchain solutions, and offchain computation

Parameters

Parameter	Type	Required	Description
address	DATA	Yes	20-byte address
blockParameter	QUANTITY|TAG	Yes	Block number or tag
