​
Overview

Melt uses deBridge (DLN protocol) for all cross-chain routing. deBridge handles token swaps and bridging in a single step — users on any supported chain can acquire or exit Melt Assets without managing multi-hop transactions.

​
Supported Chains

All chains supported by deBridge are available for Smart Buy/Sell. Key chains include: For the full list of supported chains, see the deBridge documentation.

​
Smart Buy Flow (Inbound)

  1. User signs a deBridge transaction on the source chain
  2. deBridge solver fills the order — USDC arrives on HyperEVM
  3. USDC is deposited to HyperCore via CoreDepositWallet
  4. Spot buy order executes on the Hyperliquid order book

​
Smart Sell Flow (Outbound)

  1. Spot sell order executes on Hyperliquid (Melt Asset → USDC)
  2. USDC is transferred from HyperCore to HyperEVM
  3. deBridge bridges USDC from HyperEVM to the destination chain (with optional swap to target token)

​
MeltDebridgeHook

MeltDebridgeHook is a contract on HyperEVM that auto-deposits USDC from deBridge into HyperCore, reducing inbound trades from 4 signatures to 2. When the hook is active, deBridge delivers USDC directly to the hook contract, which calls CoreDepositWallet.depositFor() to deposit into the user’s HyperCore spot balance.
