deBridge (debridge)

Cross-chain trading infrastructure with DLN (DeBridge Liquidity Network). Supports limit orders and market makers for cross-chain swaps.

Fact	Value
Category	Bridges
Family	none
Namespace	`Debridge` on ethereum, optimism, bsc, polygon, arc, base, arbitrum, avalanche
Chains	ethereum, optimism, bsc, polygon, arc, base, arbitrum, avalanche

Notes

Order-based architecture: users create orders specifying desired outcome, market makers compete to fill
Uses EVM chain IDs for destination (unlike LayerZero/Wormhole which use their own IDs)
Same DlnSource and DlnDestination addresses deployed across all supported chains
takeAmount should be set slightly below market rate to incentivize market makers
Supports cross-chain swaps natively (giveToken and takeToken can be different assets)
externalCall enables arbitrary contract execution on destination after the fill
Finality: typically 1-5 minutes (market maker fills immediately, then settles asynchronously)
Requires ERC-20 approval to DlnSource for the give token
On Arc (5042) the DLN globalFixedNativeFee() is 1000000000000000000 wei, which is 1 USDC: Arc’s native coin is USDC at 18 decimals, paid from the same balance as the USDC ERC-20 0x3600…0000 (read 2026-09-28)

On Ethereum, Debridge is a namespace: its contracts need no import.

function main() {
  // Ethereum's dlnDestination, `0xE7351Fd770A37282b91D153Ee690B63579D6dd7f`.
  require(Debridge.DlnDestination != 0);
}
