Circle Raises $222 Million for Arc at $3B Valuation as Aave Plans V4 Lending Hub

Financially, the presale was disclosed on the same day Circle reported Q1 2026 total revenue and reserve income of $694 million, up 20% year over year . USDC in circulation hit $77 billion, and onchain transaction volume reached $21.5 trillion . ARC tokens represent governance and future staking rights rather than a claim on Circle’s corporate equity, with the network’s initial token supply set at 10 billion and 60% of that allocated to ecosystem development . Circle itself will receive 25% of the initial supply to operate validator infrastructure and earn staking rewards .

Aave V4 as Arc’s Lending Backbone

On May 29, 2026, Aave Labs posted a “Temp Check”—the earliest stage in Aave’s governance process—seeking initial community feedback on launching Aave V4 on the upcoming Arc mainnet . The proposal pitches Aave V4 as the foundational lending infrastructure on a network purpose-built for capital-efficient liquidity flows from regulated institutions .

The commercial arrangement includes a concrete revenue floor. Aave Labs commits to generating a minimum of $2 million per year for the Aave DAO from the Arc deployment, totaling $10 million over five years . That figure aligns with Aave’s own strategic shift to require a $2 million annual revenue guarantee for any new chain deployment, a rule enforced to prevent liquidity from spreading too thin . The Arc proposal also outlines an initial asset set of USDC, EURC, and cirBTC, pending risk provider recommendations .

This move fits into Aave’s broader “Aave Will Win” framework, which pledges to allocate 100% of protocol product revenue directly to the DAO treasury . For Circle, securing a battle-tested DeFi protocol with a revenue guarantee strengthens Arc’s regulatory-grade narrative and gives the chain a proven lending market at launch.

Roadmap: Testnet, Mainnet, and the PoS Deadline

Arc’s public testnet went live in October 2025 and had processed more than 244 million transactions by early May 2026, with over 100 companies participating, including BlackRock, Visa, HSBC, Goldman Sachs, and AWS . Mainnet is targeted for summer 2026, and it will launch under a proof-of-authority (PoA) consensus where Circle controls the initial validator set .

The true decentralization milestone is the transition to proof-of-stake. Investor documents set a hard trigger: Circle must deliver the PoS transition by May 8, 2028, or investors can exercise repayment and contingency rights . Token lock-up periods for the presale participants extend for at least one year after the PoS transition, with potential holds of up to four years .

Network architecture details confirm Arc’s institutional focus. USDC serves as the chain’s native gas token, and the platform supports sub-second finality, opt-in privacy via zero-knowledge proofs and trusted execution environments, and full EVM compatibility . A hybrid consensus model starts with proof-of-authority before ARC token holders can stake and govern under proof-of-stake . Quantum-resistant signature schemes are also on the roadmap for the mainnet launch .

The combination of a landmark raise, a blue-chip lending protocol commitment, and a hard PoS deadline gives Arc a structure that differs from earlier layer-1 launches. Whether it attracts the institutional liquidity it was built for will become clearer once mainnet goes live, but the pieces are already locking into place.
