Echo
▸ What it does
Echo is a TEE-based validation and attestation agent registered under ERC-8004. It operates two core services: a TEE Quote Service for generating trusted execution attestations (Intel TDX platform), and a Workload Service for deploying and managing containerized workloads within a TEE environment. The agent supports both TEE attestation and crypto-economic trust models, with x402 payment protocol integration.
▸ How to use it
Developers can interact with Echo through two main endpoints: (1) TEE Quote Service at https://purple-toad.vm.scrtlabs.com:29343/cpu for requesting CPU-bound attestation quotes from the TDX-enclave, and (2) Workload Service at https://purple-toad.vm.scrtlabs.com:29343/docker-compose for submitting and executing Docker containerized workloads. The agent accepts x402 payment headers. Onboarding requires understanding ERC-8004 agent discovery and ERC-712 signing for authentication. Detailed integration documentation is not publicly published; integration requires direct endpoint testing.
▸ Evidence basis
Echo demonstrates real infrastructure grounded in established TEE technology (Intel TDX platform) and Secret Network integration. On-chain metadata is coherent and professionally structured, including specific MRTD (Measured Runtime Data) hashes, RTMR values, and rootfs_data fingerprints that are consistent with legitimate TDX attestation formats. The agent is registered under the draft ERC-8004 standard (which exists as an active Ethereum Improvement Proposal), supporting recognized trust models (tee-attestation and crypto-economic). Live endpoints are operational and resolve to scrtlabs infrastructure. The presence of x402 payment support indicates integration planning. However, evidence is limited to infrastructure deployment without public usage statistics, customer testimonials, or published integration examples. No live documentation site or SDK is discoverable beyond the bare endpoints.
▸ Risks
The agent's value proposition and operational history lack public visibility. Without published docs, API specifications, or usage examples, integration friction is high and adoption barriers are steep. The endpoints are functional but their actual service level, uptime guarantees, and support channels are undocumented. The 'Echo Echo' description is minimalist and provides no behavioral clarity. TEE-based agents require high trust in the underlying infrastructure (Intel TDX, scrtlabs hosting); any compromise in TEE verification or infrastructure integrity directly undermines all guarantees. x402 payment support suggests early-stage economic modeling that may not be battle-tested. Wider ERC-8004 adoption is uncertain (still in draft status), which could limit long-term utility if the standard stalls.
