​
Overview

The Smart Buy engine consolidates bridging, swapping, and minting into one transaction. Users on any supported chain can acquire Melt Assets without managing gas on multiple chains or performing multi-hop routing manually.

​
How It Works

1

Input Initiation (Source Chain)

User starts a transaction on an external chain (Solana, Ethereum, Arbitrum) with any supported liquid token (SOL, ETH, USDC).
2

Liquidity Aggregation

The protocol uses external liquidity aggregators to swap the input token into a bridge-compatible stablecoin (USDC) at optimal rates.
3

Cross-Chain Messaging

The stablecoin bridges to the Melt liquidity pool with a payload instruction specifying the target asset purchase.
4

Atomic Execution (HyperCore)

Upon arrival on HyperCore, the protocol executes a market buy order via the Melt Router for the target asset (e.g., QQQ) and delivers it directly to the user’s destination wallet.

​
Fee

A flat 0.50% fee covers bridging costs, routing logic, gas expenses, and operational convenience. This is frequently lower than the cumulative slippage and gas fees a user would incur performing the bridge, swap, and transfer manually.
