The Programmable Glue for the Multi-Chain World
Secure, off-chain orchestration engine connecting any blockchain, API, or system
nXCC provides the essential infrastructure to bind disparate systems into cohesive applications through:
- 🔐 Confidential Computing: JavaScript workers execute in hardware-protected Trusted Execution Environments (TEEs), ensuring code and data remain encrypted during execution
- ⛓️ Multi-Chain Native: Built-in support for 400+ EVM-compatible networks with extensible architecture for non-EVM chains
- ⚡ Event-Driven Architecture: React to on-chain events, HTTP webhooks, and P2P messages with sub-20ms latency
- 🤝 Federated Trust Model: Run your own nodes or form consortiums with cryptographic identity verification and on-chain governance
| Metric | Value |
|---|---|
| Event Latency (p99) | < 17ms |
| Event Throughput | 1,130+ events/sec |
| HTTP Throughput | 3,224+ req/sec |
| Worker Capacity | 130+ concurrent workers |
Source: Benchmark Results
nXCC uses a multi-process architecture where JavaScript workers execute inside trusted execution environments (TEEs) for confidential computation:
- Daemon: P2P networking hub managing libp2p communications, work distribution, and blockchain connections
- Enclave: TEE-based execution environment providing verifiable computation with Intel TDX/SGX support
- VM: Cloudflare Workerd runtime for isolated JavaScript worker execution
- Interface: gRPC/protobuf communication layer enabling secure inter-process communication
Start a node with Docker:
docker run --rm \
-e NXCC_DAEMON_HTTP_LISTEN_ADDR=0.0.0.0:6922 \
-e NXCC_DAEMON_LISTEN_ADDRESSES=/ip4/0.0.0.0/tcp/9000 \
-p 6922:6922 \
-p 9000:9000 \
ghcr.io/nxcc-bridge/node:latestThat exposes the HTTP API at http://localhost:6922 and keeps port 9000 open for libp2p peers, so every CLI example in the docs works immediately.
Prefer a native setup? Follow the full walkthrough in the Getting Started guide.
Enable autonomous agents to interact with multiple blockchains while protecting valuable models and decision logic within confidential computing environments.
Build sophisticated trading strategies that aggregate liquidity across networks while keeping proprietary algorithms confidential.
Cross-Chain Orchestration: Define complex workflows that span multiple blockchains, automatically handling event subscription, transaction execution, and state synchronization.
Secret Management: Built-in distributed secret sharing using peer-to-peer TEE-to-TEE protocols, governed by on-chain policies for API keys and sensitive data.
Hardware-Enforced Privacy: Intel TDX/SGX trusted execution environments provide memory encryption and remote attestation for verifiable computation.
