At a glance
Across Protocol ↗ and deBridge Finance ↗ are both intent-based bridges launched in 2022, but they tackle cross-chain value transfer with different architectures. Across relies on relayer competition with UMA optimistic verification, while deBridge uses a market-maker-driven Liquidity Network (DLN). They share a common goal—fast, low-slippage transfers—but diverge in chain coverage and extra features. Across holds $0.2B in TVL and powers bridge flows for Uniswap and Coinbase Wallet; deBridge sits at $0.1B TVL and adds native Solana support plus generic messaging. If you operate mostly inside the Ethereum L2 rollup cluster, Across likely fits better. If you need to reach Solana or BNB, or want to trigger cross-chain actions, deBridge gains an edge.
Key differences
TVL – Across holds $0.2B, double deBridge’s $0.1B. Higher TVL typically means deeper liquidity for large transfers, though both can tap external market makers.
Chain coverage – Across supports 10 chains: Ethereum, Arbitrum, Optimism, Base, Polygon, zkSync, Linea, Blast, Mode, and Scroll. The list is overwhelmingly Ethereum L2s. deBridge also supports 10 chains, but swaps zkSync, Blast, Mode, and Scroll for BNB, Avalanche, Solana, and Sonic. This makes deBridge the only intent bridge among the two with native Solana access.
Verification model – Across uses UMA’s optimistic oracle to settle relayed intents; a relayer races to fill the order, and UMA verifies after a challenge period. deBridge’s DLN leans on professional market makers who lock liquidity and get oracle-verified fulfillment—no challenge window. In practice, both deliver transfers in seconds under normal conditions.
Added utility – Across is deeply embedded in Uniswap’s and Coinbase Wallet’s bridge interfaces, giving it a vast funnel of swap users. deBridge offers generic cross-chain messaging (deBridge Messaging), letting builders trigger arbitrary calls on a destination chain. If you need to bridge an NFT or call a smart contract cross-chain, deBridge has an advantage.
Security and track record
Both protocols launched in 2022 and have no reported exploits or major incidents in our data. Across underwent audits by OpenZeppelin, Mixbytes, and Code4rena. deBridge was audited by Halborn, Zokyo, and Ackee. Audit firms differ in specialization—OpenZeppelin and Code4rena have extensive bridge experience, while Halborn and Ackee bring broader infrastructure coverage. Neither audit set raises red flags, and both codebases are considered mature after four years in production. There is no clear security edge on paper, but Across’s use of UMA’s battle-tested oracle may add an extra layer of decentralized verification.
Fees and costs
Our facts blob does not include fixed fee schedules for either bridge. Both rely on dynamic pricing driven by relayers (Across) or market makers (deBridge). Users see a quoted output amount before confirming; fees are typically a small spread plus gas reimbursement. For real-time quotes, check across.to and debridge.finance directly. In general, intent-based bridges can offer lower slippage than lock-and-mint models, but costs vary with chain congestion and available liquidity.
Which should you choose
Pick Across if:
- You mostly bridge between Ethereum L2s (Arbitrum, Optimism, Base, etc.).
- You want the deepest liquidity ($0.2B TVL) and the proven integration with Uniswap and Coinbase Wallet.
- You value UMA’s optimistic verification and a large competitive relayer pool.
Pick deBridge if:
- You need native Solana or BNB chain connectivity.
- You want generic cross-chain messaging to trigger smart contract calls.
- You prefer a market-maker model that avoids challenge periods (instant finality on fulfillment).
Verdict
The winner depends entirely on your destination chains and bridging use case. Across is the go-to for L2-centric Ethereum users who want the deepest liquidity and battle-tested relayer infrastructure. deBridge earns its place for users who require Solana, BNB, or programmable cross-chain messages. If you fall into the first camp, choose Across; if the second, deBridge is the stronger option.
