Web3 Provider Watch - 2026-10-01

Claimable

No new credits program or grant appeared in the window. Arbitrum Open House registration closes tomorrow, Oct 2, and submissions Oct 4. It advertises $115,000 in prizes and grants. Register through HackQuest, deploy on an Arbitrum chain and submit. The listing appears to render cutoff times in the viewer's local timezone, so treat the earliest reading as binding. Helius Startup Launchpad still offers approved pre-Series-A teams eight free Business-plan months through its Typeform. Colosseum closes Oct 12 at 11:59pm PT. Candide now says its free Starter plan's 2,500 mainnet UserOps have no time limit, where they previously expired after 90 days. Create a key without a card.

New services and betas

GetBlock Market SQL (Sep 29) offers SQL over market-data tables for Solana, Polymarket, Hyperliquid and Robinhood Chain, starting with a free two-hour trial; paid pricing is unpublished. GetBlock also shipped a Platform API (Sep 30) for token rotation, plan limits and CU balance. Alchemy now serves Node RPC, WebSockets and Dedicated Clusters from Tokyo, with automatic routing and no endpoint change. Envio marks HyperIndex Solana support stable. Nodit joined the Solana Developer Platform as a node provider.

Act by date

Etherscan ends opBNB Mainnet (204) and Testnet (5611) API support Oct 12. From Nov 1, Free-tier Arbitrum One and Sepolia calls draw from one shared community pool per chain and fail when it runs out. Add retry-after-reset handling, a fallback explorer API, or a paid plan. Codex now rejects new market-cap webhooks that pass pairAddress and has dropped several priceModel payload fields. QuickNode Solana gRPC port 10000 retires today; Moralis drops Sei Testnet Oct 2; The Graph ends BSC/Polygon Studio staging queries Oct 8; Etherscan's free Robinhood Chain/Arc window ends Oct 15. The Sepolia Glamsterdam fork lands Oct 6 at 13:53:36 UTC.

Changes

Thirty of the oldest rows were rechecked. The GeckoTerminal docs now put the keyless public API at about 10 calls per minute, down from the 30 recorded. Two Chainstack add-on rows were corrected: Business is $499/mo ($416 annual), and GROWTH50 is no longer shown. Docs list Solana Mainnet at 5 RPS on Developer and 50 RPS on Growth. Alchemy confirms the Transaction Simulation APIs were deprecated Sep 30. Eight other passed deadlines were dropped without completion notices.

Gaps

Maestro's pricing page returned HTTP 429, and its docs domain now serves an institutional Bitcoin-yield product, so the developer platform's status is unconfirmed. Changelogs for QuickNode, Infura/MetaMask, Dune, Helius, Bitquery, Allium, Tatum and several others could not be read. News coverage is therefore partial. Sui's archival JSON-RPC cutoff passed without an exact-day confirmation. The QuickNode Starknet Oct 5/6 conflict persists. Published documentation was checked, not live service behavior.
