Web3 Provider Watch — 2026-09-23

To claim. Coinbase CDP Paymaster advertises up to $15,000 in Base gas credits and up to $600 in signup credits; apply through the CDP Discord for up to an additional $15,000. Sign up to check eligibility and confirm whether the offers combine. Nansen Meridian offers 2× credits on API-credit purchases and 1,000 Points Hub credits through September 27; check Points Hub while signed in. Submissions close September 27 at 23:59 UTC. OnFinality advertises 35% off the first month of Growth or Accelerate. NOWNodes lists a first dedicated node at no extra charge with Business; confirm eligibility before purchase.

New coverage. Google Cloud Blockchain RPC is tracked as a public Preview: $0, up to 100 requests/second and 1 million requests/day per project, with method-specific multipliers. The official product and pricing pages confirm Ethereum Mainnet. Google’s API docs currently name Holesky, but the Ethereum Foundation marks it deprecated; active testnet support remains unverified.

Act by date. Today, QuickNode lists active Celestia and Fuel maintenance windows through 15:00 UTC; Polkadot and Injective windows start at 14:00 UTC, and Ault’s upgrade is set for 15:00 UTC. Windows may briefly interrupt RPC; the live status page lists exact times and API changes. Monad’s window ends Sep 24 at 00:00 UTC; Gravity and Sonic have Sep 24 windows. Moralis removes Moonbeam, Moonriver and Lisk on Sep 25; ETHGlobal Tokyo runs Sep 25–27. Nansen closes Sep 27. Alchemy’s legacy NFT endpoints sunset Sep 30; Sui archival JSON-RPC fallback ends around month-end, with no exact day published. QuickNode’s Solana gRPC meter/port change is Oct 1; Arbitrum Open House submissions close Oct 4.

Changes and risk. QuickNode still marks Cosmos Mainnet REST degraded at block 33,086,740; BlockPI lists Cosmos RPC/LCD components in Partial Outage. Allium’s Sep 22 Cosmos ingestion incident remains unresolved in incident history, although its current component indicator appears operational. Chainstack’s Solana Frankfurt page was still In progress just after its scheduled window, but completion and current impact could not be confirmed. Provider records now reflect current dRPC throughput rules, GetBlock plan packaging, Pocket’s unpublished public cap, Bitquery RPM tiers, and expired Helius Parsed Events terms.

Gaps. This was a bounded sweep, not a page-by-page audit: 13 of 56 data_apis official news/status pages were opened; the 43 EVM RPC records were name-scanned only. Syndica pricing returned 404, ZAN docs conflict on free throughput (270 versus 400 credits/second), mempool.space pages conflict on uptime language, and current Google testnet support is unresolved. No unsupported historical daily runs were added.
