Syndicate integrated Stylus, the execution environment of Arbitrum, into the architecture of SyndDB, its open-source SQLite database replication system oriented toward blockchain applications, reducing TEE attestation verification time from between 30 seconds and 3 minutes to under one second.
The project replaced a zkVM proof pipeline with a Rust smart contract compiled to WASM via Stylus. When a TEE service starts up, it receives an attestation from Google Cloud Confidential Space confirming it is operating with the expected code and security configuration. The Stylus contract verifies that attestation directly onchain, allowing the service to register its signing key in a single transaction.
The result was the elimination of an entire component from the architecture: from four components down to three, doing away with the prover, test network dependencies, GPU infrastructure, and per-proof costs, which ranged between $0.018 and $0.13 depending on the provider.
Internal workflows, such as collateral checks, compliance screening, or fund updates, can continue running offchain where latency and throughput demand it, while the critical checkpoint—verifying that the infrastructure is authorized before participating in settlement—becomes verifiable onchain without the need to rewrite the entire system.
