@elizaos/plugin-dcap

A plugin for verifying DCAP attestation on-chain built based on the automata-dcap-attestation.

Features

This plugin provides the following features:

• Generate DCAP attestation on TDX using the remoteAttestationProvider provided by the plugin-tee.
• Generate DCAP attestation on SGX using the sgxAttestationProvider provided by the plugin-sgx.
• Submit and verify DCAP attestation on-chain.

Future Features (coming soon)

• Support to verify DCAP attestation on more EVM networks.
• Support to verify DCAP attestation on Solana.
• Support to verify DCAP attestation using ZKVM and verify the zk proof on-chain.
• Support to topup the wallet before submitting the DCAP attestation on testnets.

Installation

pnpm install @elizaos/plugin-dcap

Configuration

1. Set up your environment variables:

EVM_PRIVATE_KEY=your-private-key-here
DCAP_MODE=PLUGIN-SGX|PLUGIN-TEE|MOCK

The EVM_PRIVATE_KEY used to submit the DCAP attestation on evm networks, please make sure it has enough balance to pay for the transaction fee.

The DCAP_MODE is used to specify the mode of generating DCAP attestation, it can be:

• PLUGIN-SGX: Use the sgxAttestationProvider in plugin-sgx to generate the DCAP attestation.
• PLUGIN-TEE: Use the remoteAttestationProvider in plugin-tee to generate the DCAP attestation.
• MOCK: Use a predefined attestation, this option is only for testing purposes.

Check the docs of plugin-sgx and plugin-tee for how to run your agent in TEE before using the SGX or TDX mode.

2. Register the plugin in your Eliza configuration:

import { dcapPlugin } from "@elizaos/plugin-dcap";

// In your Eliza configuration
plugins: [
    dcapPlugin,
    // ... other plugins
];
