The largest L2 by TVL has zero native privacy. H33 changes that.
Institutional capital is migrating to Layer 2s for lower fees and faster settlement. But the privacy gap followed them. Arbitrum processes billions in daily volume with every transaction, every position, and every counterparty interaction visible on-chain. H33 provides the compliant privacy layer that Arbitrum's DeFi ecosystem requires.
Schedule Demo Privacy Layer HubA market maker deploying liquidity on Arbitrum GMX or Camelot has their position size, entry points, and rebalancing visible to competitors. MEV bots extract value from every trade. Institutional strategies are exposed at the protocol level.
When an institution bridges assets from Ethereum to Arbitrum, the transaction graph reveals both the source and destination. Chain analysis firms track these flows in real time. The institution's cross-chain strategy is public knowledge.
Every Arbitrum DeFi interaction can carry an H33 attestation proving compliance without revealing the underlying data. The protocol receives a 32-byte commitment stored in calldata or contract storage. The trader's positions, counterparties, and strategies remain private. Regulators verify independently via the public HATS verifier.
Arbitrum is EVM-compatible. The integration is identical to Ethereum Privacy: a Solidity verifier contract, a 32-byte commitment, and the full proof in Cachee. Deploy the same contract on Arbitrum that works on mainnet.
Arbitrum's lower gas costs mean attestation anchoring costs a fraction of Ethereum mainnet. The 32-byte commitment stored in calldata on Arbitrum costs pennies. Privacy becomes economically viable for every transaction.
Arbitrum DeFi protocols -- GMX, Camelot, Radiant, Pendle -- can integrate H33 attestation checks into their smart contracts. Verify compliance per-transaction without the protocol ever touching PII.
Unlike privacy solutions built on elliptic curves, H33 attestations use STARK proofs with hash-based commitments and three PQ signature families via H33-74. No quantum migration required. Ever.
On-chain commitment check on Arbitrum. Confirm the 32-byte attestation exists and is not expired.
H33-74 PQ attestation verify. Fetch 42 bytes from Cachee and verify three post-quantum signatures.
Complete STARK proof verification. Fetch from Cachee. Run the public HATS verifier. Trust only mathematics.
32 bytes on-chain. Post-quantum attestation. Same EVM integration you already know.
