Zero surveillance, full capability

Reimagine what private collaboration looks like.

Weave doesn't ask you to trade features for privacy. Every byte is encrypted before it leaves your device. Every connection routes through Tor. Your identity lives on Ethereum — not a vendor's server.

01

On-chain identity

Your name is an ENSv2 subname — alice.acme.weave.eth. It stores your noise pubkey, onion address, and stealth keys. No account to delete, no data to request.

02

Zero-knowledge transport

Both endpoints are Tor v3 onion services. No STUN, no TURN, no ICE relay. Noise_XX encrypts every byte. The communication graph is mathematically destroyed.

03

On-chain permissions

Role-based access via a 256-bit EAC bitmap on Ethereum. Grant, revoke, add sub-admins — all signed transactions. No Slack admin panel, no AWS IAM, no vendor lock-in.

Collaboration that leaves no trace

Work happens in channels.

Weave brings the right people and context together — in encrypted channels organized by project, topic, or team. Messages stored on Arkiv, encrypted client-side before upload. Keys rotate on membership change.

Permissions without a vendor

Roles that no vendor can revoke.

Grant REGISTRAR, MODERATOR, PUBLISHER or custom org roles. Every permission change is a signed Ethereum transaction, auditable on-chain forever. No Slack admin panel, no AWS IAM — just math.

The moment a DAO uses Discord, it has surrendered its coordination graph to a corporation with a legal department. Weave is the first tool that takes this seriously.

The problem every serious DAO faces
When subpoenas arrive, Discord and Slack comply. Weave has nothing to hand over.

The cost of the status quo

Every alternative leaks something.

$630K Average enterprise Microsoft Teams spend per year (10K seats)
$35M SpartacusDAO freeze — lawsuit served via Discord DM. Discord complied.
$100B+ Enterprise communications market that Weave is built to replace
0 Servers your messages depend on — no relay, no vendor, no single point of failure

Built for every team that means it
