CLPR-10: End-to-End Integration

Epic CLPR-10: End-to-End Integration

Parent: hiero-ledger/roadmap#48
Repo: hiero-ledger/hiero-consensus-node + Ethereum contracts repo

Objective

Deploy CLPR on testnet (Hiero + Ethereum), demonstrate 1,000 successful cross-ledger messages end-to-end.

Expected Functionality

1. Testnet deployment — CLPR on Hiero testnet, ClprService on Ethereum testnet (Sepolia or equivalent).
2. Verifier deployment — HieroTSS on Ethereum, EthereumBLS on Hiero.
3. Connection — At least one bilateral Connection.
4. Connector — At least one bilateral Connector with funds.
5. Test applications — Contracts on both ledgers sending/receiving/verifying round-trip delivery.
6. 1K messages — 500 Hiero→Ethereum, 500 Ethereum→Hiero. Verified delivery.
7. Reliability metrics — Delivery rate, latency (p50/p95/p99), failures root-caused.
8. Stress testing — Queue saturation, concurrent Connectors, endpoint failures, pause/resume under load.

Dependencies

• All of CLPR-1 through CLPR-9

Risk

High — First real cross-ledger operation. Integration across two platforms.

Start by reviewing CLPR-1 through CLPR-9 and the parent roadmap issue, then identify the deployment and integration entry points in the Hiero consensus node and Ethereum contracts repository. Done means both testnet deployments, verifiers, bilateral connection and connector, round-trip applications, 1,000 verified messages, reliability metrics, and the listed stress tests are demonstrated.
