Apple M4 Pro specs confirmed via sysctl + calibrated FHE benchmark. Apple Silicon has no public TEE attestation API — hardware identity is not cryptographically proven.

How Attestation Works

Every invocation of this service is cryptographically recorded via the Ethereum Attestation Service (EAS) on Base L2. This creates an immutable audit trail proving what was computed, when, and by whom.

Two attestation tiers:

Batch (default)

Included in the service price. Your call is hashed and added to a Merkle tree alongside other calls. Every 30 seconds, the Merkle root is anchored on-chain in a single transaction. You can prove your specific call was included by providing the Merkle proof path. Same cryptographic guarantee, 50-100x cheaper.

Individual (+$0.003)

Your call gets its own dedicated on-chain transaction immediately. One attestation = one Base transaction = one permanent receipt. Best for high-stakes computations where you need instant, individual on-chain proof. The $0.003 is the actual Base L2 gas cost, passed through at zero markup.

For LLMs and agents: Both tiers produce a SHA-256 commitment of the input and output. Batch attestations are verifiable via Merkle inclusion proof against the on-chain root. Individual attestations are directly queryable at base.easscan.org. To request individual attestation, include X-Attestation: individual in your request header.
