Picks up p2pdotme/p2pdotme-sdk#52, which binds the subject address into the fraud-engine EIP-191 signed message: `{action}:{signer}:{subject}:{ts}` instead of `{action}:{signer}:{ts}`. No application code changes. Both addresses were already carried on FraudEngineSigner, so the change is internal to getSignedHeaders and this repo only needs the dependency. Part of the fraud-engine wallet-auth fix (p2pdotme/fraud-engine#41), where the backend additionally verifies on-chain that the signer is an admin of the subject smart account. The backend accepts both message formats during rollout, so this carries no ordering constraint against any other client. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Version bump only — picks up p2pdotme/p2pdotme-sdk#52, which binds the subject address into the fraud-engine EIP-191 signed message.
Why
The signed message was
{action}:{signer}:{ts}— it committed to the signing key but not to the account the request acts for. For AA smart wallets the signer is the admin EOA while the subject is the smart account, so a signature captured for one account was replayable against another inside the backend’s 5-minute freshness window. Now:{action}:{signer}:{subject}:{ts}.No application code changes
Both addresses were already carried on
FraudEngineSigner(address= subject,signerAddress= admin EOA), so the change is entirely internal togetSignedHeaders. This repo only needs the dependency.@p2pdotme/sdk@1.2.7is not published; npm is still on 1.2.6. Before merging:package.jsonContext
Part of the fraud-engine wallet-auth fix (p2pdotme/fraud-engine#41), where the backend additionally verifies on-chain that the signer is an admin of the subject smart account — that is the control that actually closes the hole; the message binding is defence in depth against cross-subject replay.
The backend accepts both message formats during rollout, so there is no ordering constraint against any other client and no window where anything breaks.
