Claimable

Helius Startup Launchpad offers approved pre-Series-A startups eight free Business-plan months, valued at $4,000. New and existing customers may apply through its linked Typeform; extra credits are excluded and approval is not guaranteed. Arbitrum Open House advertises $115,000 in competitive prizes and grants. Register through the linked HackQuest event, deploy on an Arbitrum chain, and submit the project. Registration closes Oct 2 at 17:01 and submissions Oct 4 at 15:59; the page gives no timezone. Dwellir advertises 50%+ savings for qualified teams making over one billion monthly requests; contact sales for terms.

New services and betas

Chainstack's Sep 29 notice documents Sui Mainnet GraphQL, available since Sep 28: reuse the endpoint token at /graphql, at one request unit per request. Testnet is unavailable; filtered transaction/event history reaches up to 90 days. Moralis's Sep 30 changelog clarifies Robinhood Chain Data API and Streams capabilities; internal transactions are unsupported. No qualifying new entrant was verified in the bounded search.

Act by date

Today, Alchemy deprecates Transaction Simulation APIs and selected legacy NFT methods; some NFT endpoints have no direct replacement. Sui still describes the archival JSON-RPC fallback cutoff as end of September, without an exact day.

Tomorrow, QuickNode Solana gRPC retires port 10000: migrate to 443 with x-token and review metering of 15 credits per 0.1 MB. Moralis removes Sei Testnet support Oct 2; update Data API, Streams and Datashare integrations. The Graph ends BSC/Polygon Studio staging queries Oct 8: publish to the Network, enable billing and replace endpoints. QuickNode adds Polygon Oct 6 and Hedera Oct 7 maintenance. Colosseum closes Oct 12 at 11:59pm PT.

Changes

Thirty oldest rows were checked. Dune's official docs now agree: Free is view-only; new accounts get 2,500 total trial credits for up to 14 days. Codex's Almost Free supports 4 of 15 prediction-market endpoints. Dwellir Free excludes eth_getLogs. HyperRPC docs explicitly require a token; FastNear documents public keyless RPC. These are current-documentation corrections, not newly dated launches.

Gaps

This catches up to today after the missing Sep 29 update; no historical run was fabricated. News coverage is bounded. AllThatNode archive/throughput/team-size claims and ZAN rate limits conflict. QuickNode Starknet says Oct 5 in prose and Oct 6 in its heading; Sui/XRPL status dates also conflict. Biconomy pricing and 1RPC specifications remain unverified. Published documentation was checked, not authenticated service behavior.
