Check this out ( #19 )

Hi @wu-emma @van-orton

Uses underlying MetaMask APIs to add BSC Mainnet networks. Looks like this when in use:

Add resources on the bridge so they can be used in a trusted wallet

Maintainers: quick review-assist checklist for #19 (BSC Mainnet network switch).

If you still want this feature merged, here are the main acceptance checks I’d suggest before approving:

• Uses wallet_addEthereumChain / wallet_switchEthereumChain with the correct BSC chainId (0x38), RPC URLs, block explorer URL, native currency metadata.
• Error handling: if the user rejects the MetaMask prompt, the UI should remain on the prior network and show a non-fatal message.
• Does not hardcode deprecated Goerli assumptions (Goerli is sunset); ideally the “source network” is generic (any EVM testnet/mainnet) or configurable.
• No sensitive values in the repo (API keys), and the added network metadata is safe to ship.
• Optional: add a small unit/integration test around the “switch network” helper (or at least a manual test recipe in the PR body).

If you confirm whether the bridge is intended to support BSC mainnet today (vs. only testnets), I can follow up with a tighter acceptance recipe or a minimal patch PR to align with your preferred network list.
