Implementation Checklist

• Define UniversalIntent + ChainAction schema (chainId-scoped actions).
• Implement Simple7702Account with intent verification + chain-scoped execution.
• Implement GlobalAccumulator (deterministic address, accounting, EIP-1271 validation).
• Across V3 integration: attach intent+sig as message; recipient is accumulator.
• Emit MultiChainIntentExecuted with source chains/amounts for UI.
• Indexer/UI: hide internal transfers; display consolidated event.
