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​

bun 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.

  1. Register the plugin in your Eliza configuration:
import { dcapPlugin } from '@elizaos/plugin-dcap';
