MoltsPay

• Name: MoltsPay
• URL: https://moltspay.com/
• Category: multi-chain machine-payments wrapper / seller-and-buyer middleware
• Tags: ethereum-ecosystem solana-ecosystem bnb-ecosystem
• Summary: MoltsPay is cross-chain paid-call glue. The useful part is the manifest, retry flow, wallet abstraction, and settlement routing across several schemes. Broad middleware, not a rail.
• What it does:
  • Lets providers publish paid skills and APIs by adding a moltspay.services.json manifest and running a MoltsPay server around existing functions
  • Gives buyers a CLI and SDK that create or connect wallets, discover manifests, enforce spend limits, and retry automatically after 402 Payment Required
  • Supports several settlement paths under one surface, including x402 on EVM rails, Solana SPL-transfer flows, BNB approval-style flows, and MPP on Tempo
  • Exposes browser-wallet payments for EIP-1193 wallets and Solana wallet-adapter wallets, plus an MCP server for agent hosts
  • Ships creator, buyer, and testnet tooling across TypeScript, Python, and agent-framework integrations
• Key claims:
  • The core pitch is simple: one manifest and some middleware can turn an existing service into a paid machine endpoint
  • MoltsPay is broader than a Base-only x402 wrapper because it packages several chain-specific settlement paths behind one client surface
  • The real product is the seller-and-buyer operating layer: manifests, wallet handling, retries, spend limits, and discovery
  • Keep the note on middleware and routing defaults, not on agent economy branding
• Whitepaper: No canonical standalone MoltsPay whitepaper or litepaper surfaced in this pass. The clearest current sources of truth were the official site, developer guide, canonical TypeScript and Python READMEs, package manifest, and browser-demo README; see ../whitepapers/moltspay-primary-sources-2026-05-03.md.

Internal linkages

• Strongest reads: x402 and machine-payments-protocol.

Control surface

• The leverage sits in supported payment schemes, service-manifest format, wallet abstraction, and the retry, fee-payer, and settlement defaults the middleware quietly chooses.

• Useful machine-commerce glue. Still glue above stronger payment rails and wallet systems.
