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:| Chain | Chain ID | deBridge Internal ID |

Smart Buy Flow (Inbound)
- User signs a deBridge transaction on the source chain
- deBridge solver fills the order — USDC arrives on HyperEVM
- USDC is deposited to HyperCore via CoreDepositWallet
- Spot buy order executes on the Hyperliquid order book
Smart Sell Flow (Outbound)
- Spot sell order executes on Hyperliquid (Melt Asset → USDC)
- USDC is transferred from HyperCore to HyperEVM
- 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.
