+## Summary
+
+This SIP formalizes support on the Story chain for EIP-7702 authorization 
+signatures produced via `personal_sign`.
+
+The change expands wallet compatibility for EIP-7702 type `0x04` transactions 
+while preserving the existing authorization semantics and security guarantees.

+
+## Motivation
+
+EIP-7702 relies on off-chain authorization signatures to enable delegated
+execution.
+
+In practice, many widely used wallets—especially modern browser wallets—do
+not support `eth_sign`, but do support `personal_sign`. Without accepting 
+`personal_sign`-based authorizations, these wallets cannot participate in 
+EIP-7702 flows on Story.
+
+This SIP ensures that EIP-7702 remains usable with real-world wallet 
+infrastructure.
+
+## Proposal
+
+The Story execution client SHOULD accept EIP-7702 authorization signatures 
+generated via `personal_sign`.
+
+Such signatures MUST represent a canonical, human-readable authorization 
+message that unambiguously binds:
+
+- the chain ID
+- the authorized implementation address
+- the authorization nonce
+
+The execution client MUST treat `personal_sign` and `eth_sign` authorizations 
+as semantically equivalent once verified.
+
+Transactions containing `personal_sign` authorizations MUST include an explicit 
+signaling 
+mechanism allowing the execution client to distinguish the signature type 
+during verification.

+### Alternatives Considered
+
+N/A
+
+### User Impact
+
+- Enables EIP-7702 usage for modern browser wallets
+- Improves onboarding and developer experience
+- Requires no changes to user transaction flows
+- Does not affect existing users or transactions  
+
+## Implementation Considerations
+
+- The change is limited to authorization verification logic in the execution client
+- No changes to transaction structure or consensus rules
+- Backward compatibility is preserved
+- Message construction details are considered implementation-specific
