Summary

Blast's public Starknet RPC endpoints have been decommissioned (see PR #23 on base for the full trace). Replaced both README references with the Alchemy endpoint this repo already ships in packages/snfoundry/.env.example. Identical fix to #23/#24/#25/#26 (byte-identical diff, verified), so the cascade merge stays a no-op.

  • README.md (sepolia .env setup snippet): RPC_URL_SEPOLIA — blastapi → alchemy
  • README.md (step-3 mainnet fork instruction): yarn chain --fork-network ... — blastapi → alchemy

Only the URLs changed. README.md is excluded from the scaffold-stark-2 sync workflow, so this is the only channel available to fix it.

Not included, deliberately: packages/nextjs/app/vesu/page.tsx:69 also has a dead Blast URL, but that file is already touched by the open PR #22 (fix/step-3-frontend-and-cairo-test) — left alone here to avoid a conflicting edit. The Blast faucet reference (a different, live service) is untouched.

Proof

Replacement Sepolia endpoint verified alive:

$ curl -X POST https://starknet-sepolia.g.alchemy.com/starknet/version/rpc/v0_10/_hKu4IgnPgrF8O82GLuYU \
  -d '{"jsonrpc":"2.0","method":"starknet_blockNumber","params":[],"id":1}'
{"id":1,"jsonrpc":"2.0","result":12719323}

Test plan

Blast's public Starknet RPC has been decommissioned and now returns
a JSON-RPC error instead of connecting. Swapped both README references
(sepolia setup snippet, mainnet fork instruction) for the Alchemy
endpoint this repo already ships in packages/snfoundry/.env.example.

packages/nextjs/app/vesu/page.tsx:69 has the same dead URL but is left
untouched here since it's already modified by the open
fix/step-3-frontend-and-cairo-test PR.
