# Current runtime

Find the exact chain, contracts, proving files, and security identities currently pinned by the Nullark SDK.

The SDK reads the record below as one object. If a chain, contract, fee, proving file, or proof-input identity disagrees, the flow stops.

> **Info:**
> The SDK pins this MegaETH runtime as one checked set. Use every value together.

### Public-input order

- Deposit: `commitment`, `amount`, `chainId`, `verifyingContract`, `depositContextHash`, `encryptedPayloadHash`
- Withdrawal: `root`, `nullifier`, `destination`, `grossAmount`, `fee`, `chainId`, `verifyingContract`, `proofContextHash`, `encryptedPayloadHash`

## Read it as one object

Chain ID, pool, verifiers, adapters, fee policy, selectors, and proving files belong to the same runtime. Copying one address into another runtime can make a proof or transaction target the wrong system.

| Published fact | What it confirms | What still needs checking |
| --- | --- | --- |
| Address | Expected contract location | Deployed bytecode and initialization |
| Bytecode hash | Expected code identity | Roles, current state, and operations |
| Artifact hash | Exact proving-file bytes | Circuit soundness and setup provenance |
| Fee | Package default | Fresh onchain value before proving |
