Web3 Provider Watch — 2026-10-09

Claimable

Colosseum’s Crypto World’s Fair remains open for registration and submissions until Oct 12 at 11:59 p.m. Pacific; the official page lists $840,000 in prizes and up to $2.5 million in seed funding. Register and submit. Goldsky offers a one-time $100 Starter credit without a card (pricing). Eligible pre-Series A teams can apply for eight free Helius Business months ($4,000 stated value; Launchpad). Alchemy’s startup application offers credits (amount unpublished), $5,000 in AWS credits and support (program). Dwellir advertises 50%+ custom PAYG savings for qualified teams above 1 billion monthly requests; contact sales.

New services and changes

Nodit added Arc Mainnet RPC, WebSocket, Data API, Webhook, Stream and Multichain API; use mainnet as the network identifier. Its notice also limits Arc Testnet Data API history to 90 days, except cumulative current-state data (notice). Tatum added Robinhood Chain to Notifications with all notification types via webhooks (changelog). SVRN acquired FastNEAR; the acquirer says RPC, archive and NEARDATA continue without customer changes, but the endpoint was not live-probed (announcement). Base marked the Oct 8 public RPC change complete; debug, trace and txpool are removed and the read limit is lower (status). The Graph’s Oct 8 Studio staging cutoff for BNB and Polygon passed, but completion remains unconfirmed (notice).

Act by date

QuickNode’s Starknet Pathfinder v0.24.2 maintenance is scheduled today through 23:59 UTC; L1-to-L2 overall_fee now has a 5×10^13 wei minimum. Nodit’s Aptos Testnet APIs had an expected Oct 9 return date, but no restoration confirmation was found. QuickNode Solana Agave v4.3.0 maintenance runs through Oct 11 00:00 UTC; endpoints remain available, but getInflationReward caps at 32 addresses and base58/binary encoding no longer works with v1 transactions. Colosseum submissions and Etherscan opBNB support end Oct 12, alongside QuickNode Avalanche and Sonic maintenance. QuickNode BCH and Sonic notices follow Oct 13; Hyperliquid maintenance is Oct 14. Oct 15 brings QuickNode Ethereum Geth v1.17.8 and OP-stack maintenance, Etherscan Arc/Robinhood community endpoints becoming paid, and Sui’s mid-October JSON-RPC removal placeholder. Ankr Kaia endpoints end Oct 16.

Risks and gaps

QuickNode marks Solana Mainnet degraded while investigating Alpenglow regenesis; the status notice gives no specific RPC impact (status). World Chain’s intermittent 503 incident was resolved Oct 8. BlockPI’s Sui page shows an October JSON-RPC sunset without a publication date or exact cutoff (page). The Graph cutover remains unknown, and QuickNode Sonic v2.2.4 on Oct 13 was not present in the current status-board results. Official pages conflict on Glacier pricing/quotas, BlockPI’s 50M RU period, and SXT’s free-query allowance; these terms remain unresolved.
