Merged
Conversation
…nsferWithAuthorization)
EIP-3009 JPYC ガスレス計画の前提を実機 RPC で検証する読み取り専用スクリプト (状態変更なし)。
Polygon + Kaia で (1) bytecode (2) authorizationState view (3) EIP-712 domain (eip712Domain/
DOMAIN_SEPARATOR、非公開なら WARN) (4) **署名 dry-run** (捨て鍵の有効署名で transferWithAuthorization
を eth_call し、revert 理由が balance 系=署名/domain 受理 / signature 系=domain 不一致 を判定) を確認。
Phase 0 実行結果 (2026-06-01): Polygon + Kaia とも EIP-3009 動作 + domain {name:"JPY Coin",
version:"1"} を署名 dry-run で確認 = 両 chain GO。詳細は memory:jpyc-eip3009。
