Across Protocol

Across protocol concentrates all funds in one Ethereum pool, letting liquidity do more work while reducing idle capital compared with bridge-per-chain models.

Relayers front the destination assets using their own buffers, then claim reimbursement plus a fee from the pool once the optimistic oracle confirms the transfer.

This architecture shortens transfer windows because relayers compete to deliver funds fastest, creating a market-driven race to zero latency on across bridge.

Users see guaranteed amounts: thanks to the pool’s depth and oracle verification, the across protocol quotes are final, eliminating hidden slippage.

By avoiding fragmented liquidity, the system lowers systemic risk and keeps APY for LPs consistently higher than multi-pool competitors.

Visit the across bridge interface, connect a wallet, and choose your source and destination chains—Ethereum to Arbitrum, Optimism to Base, or any supported pair.

Enter the token amount; Across Protocol instantly displays expected arrival time, fee breakdown, and relayer availability before you sign.

Advanced mode allows custom gas and a max-delay parameter; if relayers cannot fulfil in time, funds automatically settle via canonical bridges.

You can batch transfers in one transaction, saving gas across multiple addresses—ideal for payroll or DAO treasury operations.

The history panel exports CSV receipts for accounting, proving compliance to auditors without disclosing private keys.

Mobile wallets using WalletConnect integrate seamlessly, letting you execute an across bridge transfer from a phone in under a minute.

Relayers post ACX-denominated bonds that can be slashed if they deliver incorrect amounts or miss oracle-verified deadlines, aligning behaviour with user interests.

Bonds scale with volume, ensuring large relayers lock more capital and maintain skin in the game when handling big transfers on across protocol.

Fee revenue splits 90 % to relayers, 10 % to LPs, motivating rapid fulfilment while rewarding passive liquidity providers.

A dynamic fee model boosts payouts during congestion, attracting extra capacity and keeping across bridge wait times stable.

Dashboards publish fulfilment rates and latency, letting the DAO off-board under-performers through on-chain votes.

Multi-sig governance can pause specific tokens or chains if anomalies arise, adding an extra guardrail beyond the optimistic oracle’s fraud window.

These controls create a competitive yet secure marketplace where users trust across protocol without relying on a single entity.

Across protocol contracts inherit UMA’s battle-tested optimistic oracle, which settles disputes by requiring proposers to post bonds challengeable by anyone.

The codebase has undergone multiple audits, and every major upgrade triggers a new external review plus a 48-hour timelock before deployment.

Bug bounties reaching $500 000 incentivise white-hat disclosures, strengthening defence in depth for across bridge users.

All relayer addresses are public, allowing the community to monitor balance sheets and flag suspicious behaviour in real time.

Insurance funds denominated in ACX and stablecoins cover unforeseen losses, with DAO governance topping reserves whenever utilisation exceeds 25 %.

Layered security—from audits to oracles to economic incentives—makes across protocol one of the safest options for cross-rollup transfers.

ACX emissions reward liquidity providers based on share-of-pool and average utilisation, ensuring deep capital even during low-fee periods.

Emission schedules halve every two years, gradually shifting revenue reliance from token inflation to organic across bridge fees.

The DAO uses a portion of earnings to market-buy ACX and pair it with stablecoins, creating protocol-owned liquidity on DEXs.

Treasury diversification includes ETH, USDC, and yield-generating LSTs, reducing volatility and funding long-term grants.

Quarterly snapshots let token holders vote on burn events, buyback thresholds, and LP-incentive tweaks, ensuring transparent fiscal policy.

Upcoming proposals plan veACX locked voting, granting boosted rewards for long-term commitments and aligning governance with protocol health.

These levers balance growth incentives with sustainable value accrual for ACX stakeholders.

Engineers are integrating zkSync Era and Scroll, bringing the same single-pool efficiency to validity-proof chains.

A cross-chain messaging module will allow arbitrary data alongside token transfers, enabling complex DeFi operations in one across bridge call.

Partnerships with intent layers aim to let users specify desired outcomes and have Across source optimal routes automatically.

Mobile SDKs targeting React Native will open doors for wallet developers to embed across protocol directly into send screens.

Decentralised sequencer experiments are under way to reduce reliance on single-thread oracle proposals and minimise settlement risk.

By the end of 2025, Across Protocol envisions acting as liquidity backbone for a modular, multi-rollup Ethereum, all governed by an autonomous DAO.
