Board, M&A and External Review Delivery

Cold storage that inherits chain-grade durability.

Batch and deduplication in the API mirror content hashing you already use - with Arweave as the long-lived store behind each unique blob.

• Deduplicated batches: SHA-256 fingerprints (Deduplication + batch flows in the collection) let repeat objects skip re-upload - pay once per unique ciphertext.
• Gateway retrieval: Confirmed data is readable via standard Arweave gateways using the returned TX ID - no proprietary restore queue from us.
• Portable TX pointers: TX IDs are stable handles in your CMDB or backup catalog; change upstream tools without rewriting on-chain references.
• Tags on upload: File Operations accept tag maps for job name, region, or retention hints - whatever your runbooks need to filter later.

Can we send Evercore events into our own logging or security stack?

Yes. Configure HTTPS webhooks (see API docs: Webhook Management) for upload, download, and version events. Your receiver gets JSON payloads and can verify them with the X-Webhook-Signature header (HMAC-SHA256) using the webhook signing secret.

Do you offer a dedicated deployment for air-gapped environments?

Contact enterprise sales for on-premise or air-gapped deployment options. ArLocal support is available for sandboxed pre-production environments without AR spend.

What is the maximum file size for enterprise batch uploads?

Individual files up to 2GB are supported. Batch upload via POST /files/batch accepts up to 500 files per request. For bulk migrations exceeding these limits, contact sales for a dedicated migration service.
