Available E-Components
When briefing an agent, name the pattern and reference folder — not API details (those live in types.ts and the skill).
Integration model: E-Components.
Overview
| E-Component | Use case | Copy this folder |
|---|---|---|
| Precompile Interface | Precompile input, execution, results | eip-7951 |
| Bytecode Stepper | Step/run bytecode, stack/memory/gas | eip-8024 |
| Receipt Logs | Transaction receipt log list + decoded rows | eip-7708 |
Extension points
| E-Component | Scoped slots | Layout slots | Inject |

| Bytecode Stepper | — | #below | BYTECODE_STEPPER_CONTEXT |
| Receipt Logs | — | — (Teleport panel) | RECEIPT_LOGS_CONTEXT (optional) |
Precompile Interface
E-Component owns: example selection, hex input, value fields.
Exploration owns: run callback and result visualization (#result slot). Standard pre/post hardfork compare: useStandardPrecompileRun in reference folder.
Config: src/eComponents/precompileInterfaceEC/types.ts.
Non-trivial input formats (e.g. ModExp): see EIP-7883 config.
Bytecode Stepper
E-Component owns: bytecode editor, disassembly, run/step/reset, stack/memory display.
Exploration owns: configured EVM instance (:evm prop). Example presets: values[0] = unprefixed hex bytecode.
Config: src/eComponents/bytecodeStepperEC/types.ts. Companion panels: #below slot in EIP-8024.
Receipt Logs
E-Component owns: receipt log list UI, decoded row layout, empty/idle states, optional provide/inject publisher.
Exploration owns: VM/runBlock execution, mapping @ethereumjs/evm logs to ReceiptLogRow (see EIP-7708 receiptAdapter). Teleport ReceiptLogsPanelEC into #exploration-right-panel when rightPanel: true.
Types: src/eComponents/receiptLogsEC/types.ts. Format helpers: src/eComponents/receiptLogsEC/format.ts.
New E-Components
Two explorations share a pattern — or briefing identifies likely future reuse — → add src/eComponents/ and a row here (sub-round: design, test, document, then integrate).
