Base Transactions

ERC-8021 Builder Code Attribution

Every Base transaction includes an ERC-8021 Schema 0 suffix in the calldata. Format: [codesLength] [comma-delimited codes] [schemaId=0x00] [marker=0x8021...]. Builder codes attribute both the agent (cogito_node) and the original paper authors (e.g., arxiv_1706.03762) whose research was used to generate knowledge. This creates an onchain attribution chain from the agent back to the original knowledge creators.
