# Parallel v3.2 is live

*At a glance: EIP-3009 across the Parallelizer, so USDp and sUSDp can move by signature instead of by transaction.*

Parallel v3.2 has been deployed on every chain the protocol runs on. It adds EIP-3009 support to the Parallelizer, which means USDp and sUSDp can now be moved by signature instead of by transaction.

That sounds like a small change. For agent payments, it is the entire thing.

**The approve problem**
=======================

Until now, doing anything with the Parallelizer took two transactions. First you approve the contract to spend your tokens, then you swap, redeem, or deposit into Savings. That is fine when a person is sitting in front of a wallet clicking through. It falls apart when the payer is software with no human in the loop.

Standard ERC-20 gives you no way around it. The token has no concept of an off-chain authorization, so someone has to send that first approve, and it has to be the holder.

EIP-3009 changes who does the work. The holder signs a message off chain saying how much can move, to whom, and inside what time window. Anyone can then submit that signature on chain. One transaction, sent by a relayer or by the agent itself, that both authorizes and executes the operation.

**Why this matters for x402 and MPP**
=====================================

x402 and MPP are the two standards agents are paying over. They differ at the wire level, Coinbase's HTTP 402 scheme on one side and the IETF's RFC 9110 Payment auth-scheme on the other, but they solve the same problem the same way. The payment is initiated off chain and settled on chain, and the payer never submits a transaction itself.

Both require a stablecoin that supports authorized transfer by signature. Without EIP-3009, USDp could not be plugged into those flows. Not awkwardly, not with a workaround. At all.

With v3.2 it can. USDp and sUSDp now work inside x402 and MPP payment flows on the same terms as any other stablecoin that supports the standard, with the difference that they are over-collateralized, backed by yield-generating assets, and issued by a protocol the DAO controls.

**What changed**
================

The Swapper, Redeemer, and RewardHandler facets of the Parallelizer now support transferWithAuthorization. That covers swap, redeem, and Savings deposits. sUSDp, the Savings share token, supports it too, so anything interacting with Savings shares gets the same single transaction path.

Nothing else moved. Same collateral model, same depeg protection, same modular architecture. v3.2 is a focused upgrade to one module, not a rewrite.

**Savings is back**
===================

v3.2 also brings sUSDp Savings deposits back online.

In May, an attacker attempted to exploit the Savings vault. The attempt failed: automated monitoring by Hypernative detected the exploit contract within seconds and paused the protocol before a single dollar moved. We kept Savings paused while we fixed the underlying issue, and the fix went through two independent audits before returning to production, deployed together with v3.2.

One practical note for Ethereum holders: the fix ships as a new sUSDp contract on Ethereum. If you held sUSDp there, you already received the same amount of new sUSDp directly in your wallet; nothing to claim and nothing to do. On every other chain, the contract is unchanged.

**Where it is deployed**
========================

Every chain Parallel is live on: Ethereum, Base, Sonic, HyperEVM, Avalanche, Polygon, Arbitrum, Optimism, Sei, BSC, Berachain, Scroll, Gnosis, Unichain, Ink, Tac, Linea, X Layer, Plume, Plasma, Katana, Fractal, World, and Hemi.

**Audits**
==========

v3.2 was reviewed by Bail Security and Cyfrin before deployment. Audit costs were covered by the DAO treasury as part of PIP-67.
