Sharded Markets
Quick start
Prepare your wallet, choose a shard, authorize a trade, and track its resolution.
Prepare and trade
- Prepare your wallet. Install and unlock MetaMask. The app currently requires an injected EVM-compatible wallet.
- Use Hedera Mainnet. Connect chain ID
295. The app can request a network switch when you start an action. - Fund gas and assets. Hold HBAR for gas and the input token: USDC for BUY, WHBAR for SELL. Ensure required HTS token associations or automatic-association capacity exist.
- Choose a market and shard. Open Markets in the Sharded Markets app, select WHBAR-USDC, enter an exact input and minimum receive, then select an eligible target shard.
- Approve and sign. Review contract, token, amount, deadline, and network in every wallet prompt. Authorization may require an approval plus one or two typed-data signatures.
- Track resolution. Open Intents with the same wallet. Wait for
filled, or cancel while cancellation remains available.
Connection behavior: If your wallet is disconnected, the first trade click may only connect it. If the network is wrong, the next click may only switch networks. Review the updated form, then click again to authorize the trade.
