290-290: Consider clarifying the "gasless" terminology.Step 3 introduces the term "gasless x402 payments" without prior context in the document. Since SKALE's gasless transaction feature is a key differentiator, briefly explaining what "gasless" means (transactions without gas fees) would help readers unfamiliar with SKALE understand why this is relevant to the integration.

- Around line 264-271: Update the supported networks paragraph for the upstream
x402 facilitator to reflect the actual Coinbase facilitator options: replace the
incorrect list (`base`, `base-sepolia`, `avalanche`, `avalanche-fuji`) with the
correct supported networks (`Base`, `Base Sepolia`, `Polygon`, `Solana`, `Solana
Devnet`), or alternatively add a clarifying sentence stating that the x402
protocol itself is chain-agnostic but the Coinbase x402 facilitator is limited
to those specific networks unless Bindu extends support; edit the text near the
existing x402 facilitator paragraph to either swap the list or append the
clarification for facilitator vs protocol support.

🌐 Web query:
What networks does the Coinbase x402 payment protocol package support? Check the official x402 repository or documentation for the list of supported blockchain networks.
💡 Result:
Per the official Coinbase x402 docs, the reference x402 SDKs currently support two network families:
- EVM networks (
@x402/evm): any EVM-compatible chain you configure (any Ethereum L1/L2 or other EVM chain with a valid chain ID), using ERC‑20 payments via EIP‑3009 or Permit2. [1] - Solana networks (
@x402/svm): any Solana cluster you configure, supporting SPL Token Program tokens and Token‑2022 tokens. [1]
In the official Go package docs, Solana network identifiers are explicitly listed (CAIP‑2) as:
solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp(mainnet)solana:EtWTRABZaYq6iMfeYKouRu166VU2xqa1(devnet)solana:4uhcVJyU9pJkvQyS88uRDiswHXSCkY3z(testnet), with wildcardsolana:*to match all Solana networks. [2]
Separately, the Coinbase CDP facilitator (the hosted verifier/settler) lists support for Base, Base Sepolia, Polygon, Solana, and Solana Devnet (CAIP‑2 identifiers shown in the docs). [1]
Sources: [1] Coinbase x402 “Network Support” docs; [2] official github.com/coinbase/x402/go package docs (Supported Networks section.
Correct the list of supported networks for the upstream x402 facilitator.
The documentation lists supported networks as base, base-sepolia, avalanche, and avalanche-fuji, but the official Coinbase x402 facilitator documentation indicates support for Base, Base Sepolia, Polygon, Solana, and Solana Devnet. The x402 protocol itself is flexible and supports any EVM-compatible chain or Solana cluster you configure, but the Coinbase facilitator has specific network restrictions. Update the documentation to reflect the actual supported networks from the facilitator or clarify whether Bindu extends facilitator support beyond Coinbase's default offerings.
