AppKit's built-in networks advertise rpc.walletconnect.org/v1/?chainId=…&projectId=… as the chain RPC. Wallets reject that query-string URL as "Invalid URL" when adding/switching the network — Trust showed "Invalid URL", desktop MetaMask looped on Switch Network, and the mobile buy failed because the switch to Amoy never completed. Clone the chain with our clean public RPC before handing it to AppKit/Wagmi. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
InstantAdPay — site
Membership advertising with immutable on-chain settlement. Zero-dependency Node server (RM Circle pattern): static pages + JSON API + SSE ledger.
Architecture
server.js— http server: pages,/api/*,/join/<id>sponsor links, SSE feedchain.js— contract reader + persistent event indexer (free public RPCs)auth.js— SIWE wallet sign-in (EIP-4361), sessions in the volumeaccounts.js— site-side records only (free members, first-touch sponsor attribution, handles). The CHAIN is the source of truth for money/credits.public/— landing, live ledger, member area; no client libraries
Chain flip (rehearsal → mainnet)
Everything chain-specific lives in data/config.json (volume):
{contract, chainId, chainName, explorer, rpcs, deployBlock}.
Defaults point at the Amoy rehearsal deployment. Launch = deploy the
mainnet contract, wipe accounts.json/sessions.json/chain-index.json,
PATCH /api/admin/chain with the mainnet values, set rehearsal:false via
/api/admin/site. Same code, different config.
Run
PORT=3100 node server.js # DATA_DIR defaults to ./data
Admin API auth: Authorization: Bearer $ADMIN_PASSWORD.
Spec: ../CONTRACT-SPEC.md (v1.0.3-frozen). Contracts: ../contracts/.
