XAUConnect Gold Router

XAUConnect (xauconnect.com) is my existing non-custodial DEX aggregator for 7 chains (6 EVM + Solana), with Gold Curve, a launchpad for gold-themed Solana tokens. Live but early (self-reported: 12 registered users, about $10.34 all-time swap volume). That is baseline. The NEAR Intents layer is new, built in the window, and disclosed in the README.

Problem: people wanting gold hold stablecoins spread across chains. A Gold Curve buyer needs SOL or USDC on Solana. Today that means a bridge and a DEX per chain, gas everywhere, and no single cost view.

XAUConnect Gold Router uses NEAR Intents (1Click API) for two jobs:

1. Gold from any chain: balances on several chains -> XAUT, to my wallet or my NEAR Intents balance.
2. Fund from another chain: an EVM stablecoin or ETH -> the exact SOL/USDC a Gold Curve buy needs, in my Solana wallet, with a graduation warning, then the existing token page.

It quotes all options in parallel, applies a spending policy (USD caps, slippage, allowlists), and ranks by cost in bps and ETA. The deposit flow is off by default. It needs an explicit confirm plus a server switch, re-quotes stale plans, and aborts if the price moved. It returns unsigned transactions; my own wallet signs. No keys or funds are held.

Ships as a CLI, an HTTP API agents can call within limits, and ready-to-apply patches for XAUConnect: a NEAR Intents venue, wallet deposit helpers, a status timeline and a Fund-from-another-chain panel.

Live dry quotes: 100 USDC on Arbitrum -> XAUT about 25 bps into a NEAR Intents balance vs 50 to a wallet, so it picks the cheaper. 20 USDC on Polygon -> 0.1975 SOL at 17 bps.

NEAR is the settlement layer linking XAUConnect's EVM and Solana sides.
