Seedless Threshold MPC

BitShard brings Self-Custody, reinvented to every wallet and agent.

Spin up distributed key generation, orchestrate threshold signing, and plug directly into Bitcoin and any EVM-compatible network through MPC-first SDKs, Docker infrastructure, and wagmi tooling.

Architecture

How BitShard orchestrates secure key generation and signing across parties

Every phase is WebSocket-coordinated, leverages DKLs23 for threshold ECDSA, and ships with Docker images so teams can deploy the signing parties anywhere.

Phase 01

Distributed Key Generation (DKG)

Parties exchange commitments over secure WebSockets, derive isolated shares, and never reconstruct a full private key.

Transaction Management & Signing

BitShard standardises Transaction signing via EIP-1193 compatible helpers that produce threshold-signed payloads.

Product Pillars

Seedless infrastructure engineered for both retail & institutional teams

One SDK drives the entire lifecycle: onboarding, approvals, share refresh, and transaction orchestration across Bitcoin and EVM-compatible networks.

API-first Architecture

Type-safe SDK with documented WebSocket flows and REST API endpoints, so builders integrate Seedless MPC wallet creation and signing in minutes.

Enterprise Ready

MCP server, role-based approvals, and Docker signers that plug into existing SOC2 compliant infrastructure.

Military-Grade Security

Shares never co-locate. Mobile, extension, and Docker images keep shards isolated and refreshable on schedule.

Resilient Recovery

Social recovery workflows and share rotation protocols ensure instant wallet restoration even if a device is lost.

Universal Chain Support

Bitcoin support + EIP-1559 for EVM compatible networks.

Agentic Automation

Composable automations with n8n and Zapier to trigger intents, approvals, reconciliations and compliance use cases.
