Hooks enable arbitrary contract calls after cross-chain trades. This unlocks powerful workflows: move assets across chains, swap, and deposit into a protocol — all in a single user action.

​
What Are Hooks?

Hooks are contract calls that execute after your cross-chain swap completes. They let you trigger actions like deposits, staking, or liquidity provision on the destination chain without requiring users to manage multiple transactions.

​
DLN Hooks

DLN hooks are available for integrations using the deBridge Liquidity Network API.
  • Hooks: Execute after cross-chain swaps — deposit, stake, add liquidity
  • Gas payment: User pays gas on source chain
  • Caller identity: DLN contract (not user’s EOA) — target protocol must support beneficiary parameters like onBehalfOf

​
DLN Hook Options

EVM chains support configurable hook behavior:
  • isNonAtomic (true/false): When false (atomic), the hook executes within the same transaction as order fulfillment. When true (non-atomic), the hook executes in a separate transaction.
  • isSuccessRequired (true/false): When true, hook failure prevents the order from being filled. When false, the order completes even if the hook fails.
Solana only supports non-atomic success-required hooks. The hook executes as serialized instructions after order fulfillment. DLN Hooks Guide | EVM Hook Anatomy
