Summary:
This proposal introduces Parallel v3.2, a focused upgrade to the Parallelizer module that adds EIP-3009 (TransferWithAuthorization) support, making USDp and sUSDp natively compatible with agentic payment standards x402 and MPP.
Context:
Agentic payment protocols, x402 and MPP (Machine Payments Protocol), are emerging as the dominant standards for AI-agent and machine-to-machine transactions. Both require stablecoins capable of authorized transfers via signature: a payment initiated off-chain and settled on-chain without the payer needing to submit a transaction directly. The standard ERC-20 interface does not support this; EIP-3009 does.
Parallel v3.2 implements EIP-3009 across the Parallelizer module (swap, redeem, and Savings paths), making USDp and sUSDp first-class citizens in these payment ecosystems.
Rationale:
I. Why EIP-3009 now
x402 adoption is accelerating. As of April 2026, x402scan tracks over 1.35 million transactions, $1.48M in settled payment volume, 72,150 active paying agents, and 960 live payment endpoints. With daily transaction counts reaching ~131,000. Both x402 and MPP require stablecoins that support authorized transfers via signature. Without EIP-3009, USDp cannot be properly integrated into these payment flows at all. The window to establish USDp as a first-class payment token in this ecosystem is now.
II. What changes in v3.2
Today, interacting with the Parallelizer (swap, redeem, Savings deposit) requires the user to first submit an âapproveâ transaction, then the actual operation, two transactions. EIP-3009 eliminates this: the user signs an authorization message off-chain, and any relayer or agent can submit a single transaction that both authorizes and executes the operation. This is what makes USDp usable in x402 and MPP flows, where there is no human in the loop to sign two sequential transactions.
Concretely, the Swapper, Redeemer, and RewardHandler facets of the Parallelizer gain âtransferWithAuthorizationâ support. sUSDp (the Savings shares token) also gains this support for interactions with it.
III. Deployment scope
Parallel v3.2 will be deployed on all chains where Parallel is currently active: Ethereum, Base, Sonic, HyperEVM, Avalanche, Polygon, Arbitrum, Optimism, Sei, BSC, Berachain, Scroll, Gnosis, Unichain, Ink, Tac, Linea, X Layer, Plume, Plasma, Katana, Fractal, World, Hemi.
We are requesting $1,000 to support the deployment of Parallel v3.2.
IV. Audits
v3.2 will be audited by Bail Security and Cyfrin. Bail Security audit started earlier this month, Cyfrin audit is scheduled to start early in May. Total audit costs is $16,500, with $6,500 for Bail Security (we got $1,500 discount as long-term partners), already paid by us in order for the audit to start as soon as possible (payment transaction here), and $10,000 for Cyfrin. We are requesting a reimbursement of audit costs by the DAO.
Note: Cooper Labs doesnât make any profit on audit costs.
Means:
- Human Resources: Cooper Labs (service provider) handles the full end-to-end execution: audit coordination, finding remediation, deployment across all chains. No additional human resources are required from the DAO.
- Treasury Resources: $6,500.00 for the Bail Security audit, $10,000 for the Cyfrin audit, $1,000.00 to Cooper Labs in order to cover deployment costs. Total: $17,500.00
Technical Implementation:
On Ethereum:
- Transfer $17,500 from the DAO Treasury to 0x876C4D1Bd31af0d99191fC896F15a3A97D71aaB3 (Cooper Labs)
On all chains where the protocol is deployed:
- Upgrade the protocol from Parallel v3.1 to Parallel v3.2
