--- url: https://aelmanaa.github.io/hardhat-kms/live-proof.md --- # Live proof Audience: contributors and reviewers who want on-chain evidence that the plugin signs with real KMS keys. Status: the latest run of the live suite on Sepolia ([#44](https://github.com/aelmanaa/hardhat-kms/issues/44)), with the transaction matrix of [#144](https://github.com/aelmanaa/hardhat-kms/issues/144). `pnpm run docs:live-proof` renders this page from `test/live/proof.json`, which the run wrote; do not edit it by hand. ## Run | Field | Value | | ---------- | ------------------------------------------------------------------------ | | Date | 2026-10-16, blocks mined from 06:22:24 to 06:26:36 UTC | | Commit | `eeec83b` | | Chain id | 11155111 (Sepolia) | | Blocks | 11925619 to 11925638 | | Command | `HARDHAT_KMS_LIVE_NETWORK=sepolia pnpm run test:live` | | Providers | AWS KMS, Google Cloud KMS and Azure Key Vault, in parallel | | Gas prices | 1.00 to 1.00 gwei for types 0 and 1; 0.00 to 1.00 gwei for types 2 and 4 | Every transaction below was signed by the provider's KMS key through the plugin, except where a case says another key signed. The suite waited for each receipt and checked its status, its sender and its type against the case table in `test/live/matrix.ts`. A run that misses a receipt for any live cell fails, and writes no proof. The `personal_sign` and `eth_signTypedData_v4` signatures are checked with `eth_call`: `LiveCheck` rebuilds the EIP-191 and EIP-712 digests on chain and recovers the KMS account with `ecrecover`. These checks send no transaction, so they have no hash. Each account ends the run with no code. Its EIP-7702 delegation is cleared by the last case, and the throwaway key whose authorization the account sent is cleared by a second transaction in the same case. Slot 0 of each account's storage keeps the count that the delegated `add` wrote; clearing a delegation does not reset storage. ## Coverage matrix One decision per action and type. Live cells run on Sepolia and on the fork, fork cells only on the fork, unit cells only in the unit or integration tests, and refused cells are refused by the plugin before any request. Each live and fork cell runs once per provider. | Action | Type 0 (legacy) | Type 1 (EIP-2930) | Type 2 (EIP-1559) | Type 3 (EIP-4844) | Type 4 (EIP-7702) | | -------------------------------------------------- | --------------- | ----------------- | ----------------- | ----------------- | ----------------- | | ETH to another EOA | Live | Live | Live | Refused (r) | Live | | ETH to self | Fork (a) | Fork (a) | Live | Refused (r) | Live | | Contract deploy | Live | Live | Live | N/A (b) | N/A (c) | | Contract call | Live | Live | Live | Refused (r) | Live | | Payable contract call | Live | Live | Live | Refused (r) | Live | | Reverting transaction, mined with status 0 | Fork (d) | Fork (d) | Live | Refused (r) | Fork (d) | | Replacement (same nonce, higher fee) | Fork (e) | Fork (e) | Fork (e), unit | Refused (r) | Fork (e) | | EIP-7702 set delegation | N/A (f) | N/A (f) | N/A (f) | N/A (f) | Live | | EIP-7702 clear delegation | N/A (f) | N/A (f) | N/A (f) | N/A (f) | Live | | Sponsored: we send another key's authorization | N/A (f) | N/A (f) | N/A (f) | N/A (f) | Live | | Sponsored: another account sends our authorization | N/A (g) | N/A (g) | N/A (g) | N/A (g) | Fork (h) | | Signature | Decision | | ---------------------- | -------- | | `personal_sign` | Live | | `eth_signTypedData_v4` | Live | | `eth_sign` | Live | Reasons: * (a) A self-send of type 0 or 1 takes the same fill and signing path as a send to another EOA of the same type, which runs live. Self-sends of types 2 and 4 run live. * (b) EIP-4844: "`to` … MUST NOT be `nil` … blob transactions cannot have the form of a create transaction." The plugin refuses blob transactions anyway. * (c) EIP-7702 gives `destination` the semantics of EIP-4844: "this implies a null destination is not valid." * (d) The revert path does not depend on the type: the receipt has status 0, and the next transaction whose nonce the plugin fills carries the account's count after the revert, which the type 2 case proves on Sepolia. The type 4 case also checks that the delegation stays applied, since EIP-7702 does not roll back processed authorizations when execution fails. * (e) A replacement needs a transaction that stays pending. On Sepolia that means pricing one below the base fee through a load-balanced public RPC, where a backend may refuse it or mine it, and a stuck nonce blocks the account. In fork mode the case turns automine off with `evm_setAutomine`, sends, sends the replacement with double the fees, mines, and checks that only the replacement was mined. * (f) EIP-7702: only a set-code transaction (type 4) carries an `authorization_list`, and the list must not be empty. The plugin picks type 4 exactly when `authorizationList` is present and refuses a `gasPrice` next to it. * (g) The other account signs the outer transaction; the plugin signs only the authorization, which only type 4 carries (EIP-7702). * (h) On Sepolia the KMS account would first have to fund a second key, and ETH would stay there. In fork mode `anvil_setBalance` funds a throwaway local sender for free. The KMS key signs the authorization with its current nonce, not nonce + 1, since another account sends it. * (r) EIP-4844 blob transactions: the plugin refuses them before any request. Unit tests: * `packages/hardhat-kms/test/unit/rpc/transaction-filler.test.ts`, "refuses blob transactions before any request": `eth-to-eoa/eip4844`, `eth-to-self/eip4844`, `call/eip4844`, `payable-call/eip4844`, `revert/eip4844`, `replacement/eip4844` * `packages/hardhat-kms/test/integration/send-lock.test.ts`, "keeps an explicit nonce and sends same-nonce replacements with higher fees": `replacement/eip1559` Not in the matrix: * CREATE2 factory deploy: The plugin sees a call to the factory, which is the contract call row. It never builds the CREATE2 address itself.
