EVM Transaction Preflight — ChainEvidence

Under maintenance

Try for free

Inspect unsigned Base transactions before execution. ChainEvidence decodes calldata, simulates calls, detects proxies and privileged control, verifies contract source, and returns deterministic evidence with coverage and block provenance—without SAFE/SCAM labels or private keys.

0.1.0-alpha.15 — 2026-08-13

Publication-only release candidate; no core analysis-rule changes.
Rewrite the public README around user value, input/output, evidence semantics, security boundaries, and limitations.
Remove stale private-deployment and pre-launch instructions from the Store-facing README.
Add docs/store-listing.md with copy-ready Actor/SEO descriptions, positioning, keywords, and sample input.
Advance package/report metadata to alpha.15 so the Store candidate is unambiguous.

0.1.0-alpha.14 — 2026-08-13

Keep verified ABIs internal instead of embedding full ABI arrays in paid reports.
Add compact ABI metadata (abiAvailable, entry/function/event counts) to verification evidence.
Add regression coverage proving serialized reports do not contain raw abi arrays.
Advance package, CLI, report, and cloud-smoke metadata to alpha.14.

0.1.0-alpha.13 — 2026-08-13

Add deterministic detection for legacy ZeppelinOS proxy storage slots (org.zeppelinos.proxy.implementation / org.zeppelinos.proxy.admin).
Fix a real-world proxy false negative observed on Circle USDC on Base, whose FiatTokenProxy uses the pre-ERC-1967 ZeppelinOS slot scheme.
Add regression coverage for legacy ZeppelinOS implementation/admin slots.
Advance package, CLI, report, and cloud-smoke metadata to alpha.13.

0.1.0-alpha.12 — 2026-08-13

Move .actor/ from apps/apify-actor/.actor/ to the repository root so Apify CLI uploads the full monorepo as the Actor root.
Remove dockerContextDir; the repository root is now the Docker build context by construction.
Update deployment instructions: run apify validate-schema and apify push from the repository root.
Strengthen actor:package:validate to reject nested/out-of-root Docker context configurations.

0.1.0-alpha.11 — 2026-08-13

Fix Apify CLI schema validation by adding the required description to the options input field.
Fix Apify deployment version format: .actor/actor.json now uses 0.1 (Apify MAJOR.MINOR) while package/analysis versions remain semantic prerelease versions such as 0.1.0-alpha.11.
Strengthen actor:package:validate to reject invalid Apify Actor versions and any top-level input field without a description before apify validate-schema/apify push.
Update cloud smoke assertions and user-facing version metadata to alpha.11.

0.1.0-alpha.9 — 2026-08-13

Fix the local PPE verifier being unreachable because Actor.main() terminates the Node.js process on completion.
Run the Apify Actor in a child process and keep the harness in the parent process.
After the Actor child exits, verify the default dataset and charging_log dataset and print an explicit LOCAL_APIFY_PPE_PASS or LOCAL_APIFY_PPE_FAIL sentinel.
Keep the production Actor unchanged; the process split exists only in the local PPE harness.

0.1.0-alpha.8 — 2026-08-13

Confirmed the alpha.6 manual run can now reach Actor completion without the previous missing-input exception when Apify/Crawlee share a storage root.
Pin both APIFY_LOCAL_STORAGE_DIR and CRAWLEE_STORAGE_DIR to the same absolute local path in the PPE harness.
Pin local default key-value store and dataset IDs to default.
Add a post-run PPE verifier that checks for a ChainEvidence report in the default dataset and an event record in the charging_log dataset.
Successful local PPE smoke test now ends with LOCAL_APIFY_PPE_PASS; missing report/charge artifacts make the command fail.
Add visible local harness diagnostics so silent Actor completion is no longer ambiguous.

0.1.0-alpha.6

Fix local Apify PPE harness losing INPUT.json because Crawlee purges default local storage on Actor.main() startup.
Set CRAWLEE_PURGE_ON_START=false only in the local harness.
Validate prepared INPUT.json before launching the Actor and print the absolute local storage root for diagnostics.
No production Actor lifecycle change.

0.1.0-alpha.5 — 2026-08-13

Marked the first real Base current-state transaction smoke test as externally verified on Windows: PASS.
Added a live Base corpus harness (npm run test:live:corpus) with a strongly asserted Circle USDC approval plus complex public transaction robustness cases.
Added a Windows-friendly local Apify PPE harness (actor:install, actor:prepare, actor:local:ppe).
Added a safe unsigned sample Base transaction for Actor local testing.
Documented the Apify PPE double-charge guardrail: use custom tx-preflight, keep apify-actor-start, and disable apify-default-dataset-item when the custom event is configured.
Bumped analysis/CLI version to alpha.5.

0.1.0-alpha.4 — 2026-08-13

Split byte DATA validation from JSON-RPC QUANTITY parsing.
Added regression coverage for odd-nibble quantities such as 0xabc.
Fixed live Base block-number parsing.

0.1.0-alpha.3 — 2026-08-13

Added retry/failover behavior for transient RPC failures including HTTP 429.
Split current-state and historical live validation.

0.1.0-alpha.2 — 2026-08-13

Added transaction-hash importer and live Base harness.

0.1.0-alpha.1 — 2026-08-13

Initial deterministic core, CLI, tests, and Apify wrapper.

0.1.0-alpha.10 — 2026-08-13

Added

Apify dataset schema with field metadata and an evidence-focused Output view for Console/MCP consumers.
npm run actor:package:validate to validate cloud packaging invariants before deployment.
npm run actor:cloud:smoke to start a private Apify Cloud run through the API and assert a real ChainEvidence report.
docs/apify-cloud-deploy.md private-first deployment and monetization gate checklist.
Root .dockerignore for the monorepo Docker build context.

Changed

Cloud Dockerfile now sets the root work directory explicitly and keeps the two-stage root-build / Actor-runtime dependency flow.
Actor definition now links the dataset schema and project changelog.
Analysis/package versions advanced to alpha.10.

Validation

TypeScript build PASS.
Offline regression suite 9/9 PASS.
Apify package validator PASS.
JSON parse and Actor/helper syntax checks PASS.
Cloud push/run is intentionally not marked PASS until executed against the user's authenticated Apify account.
