Why Arc?

One asset for inference and network fees. Arc gives both sides a confirmed record of USDC settlement.

Built around USDC

Arc gives MPPI a settlement network built around USDC. Funding, provider payouts and network fees use the same asset, so the network does not require a separate volatile gas token.

Arc property / Why it fits MPPI

USDC as the native gas asset: Network fees are expressed in the same asset as inference payments. Circle sponsorship is a separate wallet service; it does not fund inference.
Deterministic finality: Arc documents sub-second finality at block commitment. Confirmed funding, capture and refunds provide clear chain effects for session accounting.
Smoothed fee adjustments: Arc smooths short demand spikes. Actual MPPI contract costs still depend on the transaction and network conditions.
EVM contracts: MPPI's Solidity contract, ERC-8004 identity and supported wallet integration work within a verified Arc deployment.

MPPI uses six-decimal ERC-20 USDC amounts. Arc's native gas interface uses 18 decimals; both interfaces share one balance. Arc's finality figure describes the network, not the end-to-end latency of an MPPI request or Circle wallet operation. Pending and unknown operations still need reconciliation.
