Dependencies

EdgeApp/edge-exchange-plugins#457

Requirements

If you have made any visual changes to the GUI. Make sure you have:

• Tested on iOS device
• Tested on Android device
• Tested on small-screen device (iPod Touch)
• Tested on large-screen device (tablet)

Description

Enable the NYM swap provider (added in edge-exchange-plugins#457).

• src/util/corePlugins.ts: register nymswap: ENV.NYM_SWAP_INIT in swapPlugins. The swap plugin id is nymswap, intentionally distinct from the nym currency plugin id (edge-core-js keys all plugins in one namespace; reusing nym silently drops the swap plugin).
• src/envConfig.ts: add NYM_SWAP_INIT ({ apiKey }, sent as the x-api-key header).

Configure the key in env.json:

"NYM_SWAP_INIT": { "apiKey": "<key>" }

NYM swaps run on NYM's livenet (production) backend; the endpoints live in edge-exchange-plugins#457. GUI wiring is endpoint-agnostic, so this PR is unchanged by the testnet → livenet migration.

Verified end-to-end in the iOS simulator: ran a real mainnet swap My Ether 4 (USDT on Ethereum) → My Nym (native NYM on Nyx). The quote resolved "Powered by NYM" (6.006 USDT → 326.99 NYM) and slide-to-confirm broadcast the on-chain payin (max network fee 0.0002709 ETH), with the order entering processing ("Congratulations! Your exchange is being processed", tx category Exchange: To NYM).

Note

Low Risk
Standard swap-plugin registration and optional API key config only; no changes to auth, payments, or wallet key handling.

Overview
Enables the NYM centralized swap provider in the app by wiring the existing nymswap exchange plugin into core plugin registration and environment config.

src/util/corePlugins.ts adds nymswap: ENV.NYM_SWAP_INIT alongside other CEX swap plugins. The id is nymswap, separate from the nym wallet/currency plugin, so both can load in the shared plugin namespace.

src/envConfig.ts introduces NYM_SWAP_INIT with an optional apiKey (for the x-api-key header on NYM’s API). Operators enable it via env.json, e.g. "NYM_SWAP_INIT": { "apiKey": "<key>" }.

CHANGELOG notes the new provider. Swap routing/quote UI behavior follows the same pattern as other env-gated swap plugins; the NYM backend lives in edge-exchange-plugins.
