• No

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 is testnet-only for now.

Verified end-to-end in the iOS simulator: created Sepolia ETH + NYM wallets, funded Sepolia from a faucet, and ran a real swap My Sepolia → NYM. The quote resolved "Powered by NYM" (0.0121 ETH → 1,093.85 NYM) and slide-to-confirm broadcast the on-chain payin (Sepolia balance 0.025 → 0.012806 ETH; nonce 1), with the order entering processing.

Note

Low Risk
GUI registration and env schema only; swap execution lives in edge-exchange-plugins and is gated by API key and testnet-only NYM support.

Overview
Registers the NYM centralized swap provider in the GUI so quotes and confirmations can show “Powered by NYM” when the exchange plugin is enabled.

nymswap is wired in swapPlugins with NYM_SWAP_INIT (apiKey in env.json, sent as x-api-key). The id is intentionally separate from the nym currency plugin so both can load in the same plugin namespace.

Also adds testID="confirmSliderThumb" on the slide-to-confirm thumb in SafeSlider (snapshot/test updates only).
