Across Protocol (ACX) on Bybit: A Comprehensive Guide to Bridging Assets and Earning Yield

02Understanding Across Protocol: How It Works

Across Protocol distinguishes itself from other cross-chain bridges through its innovative architecture. Unlike traditional bridges that require wrapping assets or maintaining multiple liquidity pools across different chains, Across utilizes a pooled liquidity model and a network of bonded relayers to streamline the bridging process. This results in faster transaction times and lower fees for users.

The core principle behind Across Protocol is its reliance on a single liquidity pool on the destination chain. When a user initiates a bridge transaction, relayers compete to fulfill the request by providing the requested asset from the pool. These relayers are bonded with capital, which acts as collateral against potential malicious behavior. This bonding mechanism provides an additional layer of security and incentivizes relayers to act honestly.

To illustrate, imagine you want to bridge ETH from Arbitrum to Ethereum. Instead of locking your ETH on Arbitrum and minting a wrapped version on Ethereum (like some older bridge designs), Across utilizes its ETH liquidity pool on Ethereum. Relayers observe your transaction on Arbitrum and race to provide you with ETH from the Ethereum pool. The fastest and most reputable relayer wins the bid, and you receive your ETH on Ethereum almost instantly. The relayer is then reimbursed from the Arbitrum side using a slower, more secure process, ensuring the system remains balanced.

• Pooled Liquidity: A single liquidity pool on the destination chain simplifies the process and reduces fragmentation.
• Bonded Relayers: Relayers are incentivized to act honestly through a bonding mechanism, enhancing security.
• Optimistic Verification: Fraudulent transactions can be challenged within a specific timeframe, adding another layer of protection.
• Capital Efficiency: By eliminating the need for wrapped assets and multiple liquidity pools, Across maximizes capital efficiency.

03Across Protocol (ACX) Token: Utility and Governance

The ACX token is the native governance token of Across Protocol. It plays a crucial role in the protocol's decentralized governance and provides holders with the ability to shape the future direction of the project. Holding ACX grants you the right to participate in voting on key decisions, such as protocol upgrades, fee adjustments, and the allocation of resources.

Beyond governance, the ACX token also has potential utility within the Across Protocol ecosystem. While specific implementations may evolve over time, ACX could be used for things like: Staking to earn rewards from protocol fees, Providing Liquidity to the Across pools and receiving ACX incentives, and Paying for Bridge Fees at a discounted rate. As the protocol matures, additional use cases for the ACX token may emerge.

Currently, on Bybit, you can trade ACX against USDT. The price of ACX, like other cryptocurrencies, is subject to market volatility. As of today, March 12, 2026, ACX is trading around $0.75, showing a 5% increase in the last 24 hours, driven by the increasing adoption of Across Protocol within the DeFi community. Remember that past performance is not indicative of future results and crypto trading always carries the risk of loss.

04Bridging Assets with Across Protocol on Bybit: A Step-by-Step Guide

While Bybit doesn't directly integrate Across Protocol into its UI, you can easily bridge assets using Across Protocol through your Bybit-linked wallet (like Metamask or Trust Wallet). This involves withdrawing your assets from Bybit to your wallet and then using the Across Protocol interface to initiate the bridge transaction. Make sure to have some ETH in your wallet to cover gas fees.

Before you start, always double-check the official Across Protocol website URL to avoid phishing scams. As of 2026, the official website is still across.to. Also, verify the receiving address on the destination chain. A small error can lead to a permanent loss of funds.

The following steps outline how to bridge assets from a Layer-2 network like Arbitrum to Ethereum using Across Protocol.

• Step 1: Withdraw Assets from Bybit: Log in to your Bybit account and navigate to the withdrawal section. Select the asset you want to bridge (e.g., ETH) and choose the corresponding Layer-2 network (e.g., Arbitrum). Enter your wallet address (e.g., Metamask) and confirm the withdrawal. Be aware of withdrawal fees on Bybit, which may vary depending on the asset and network.
• Step 2: Connect to Across Protocol: Go to the official Across Protocol website (across.to) and connect your wallet. Ensure your wallet is connected to the source network (e.g., Arbitrum).
• Step 3: Initiate the Bridge Transaction: Select the asset you want to bridge, the source network (Arbitrum), and the destination network (Ethereum). Enter the amount you want to bridge and review the estimated fees and slippage. Confirm the transaction in your wallet. The transaction fees are dynamic based on network conditions and liquidity.
• Step 4: Wait for Confirmation: The bridge transaction will typically take a few minutes to complete. You can track the progress of your transaction on the Across Protocol interface or through a block explorer. Once the transaction is confirmed, your assets will be available in your wallet on the destination network (Ethereum).

05Earning Yield with ACX: Staking and Liquidity Providing

While specific yield opportunities on Bybit related to Across Protocol may vary, the primary ways to earn yield with ACX involve staking and providing liquidity directly on the Across Protocol platform. These opportunities are subject to change and availability, so always check the official Across Protocol website for the most up-to-date information.

Staking ACX: By staking your ACX tokens, you can potentially earn rewards from protocol fees. The staking mechanism incentivizes holders to lock up their tokens and participate in the long-term success of the protocol. The rewards are typically distributed proportionally to the amount of ACX staked and the duration of the staking period. The APY (Annual Percentage Yield) for staking ACX fluctuates based on the overall staking participation and the protocol's revenue.

Providing Liquidity: You can also earn yield by providing liquidity to the Across pools. By depositing assets into the pools, you help facilitate cross-chain transfers and earn a share of the transaction fees generated by the protocol. This is a more active form of participation, as it requires you to monitor the pools and manage your liquidity positions. The returns from liquidity providing can be higher than staking, but it also comes with the risk of impermanent loss.

For example, if you stake 1000 ACX tokens and the APY is 10%, you could potentially earn 100 ACX tokens over the course of a year, assuming the APY remains constant. Similarly, if you provide $10,000 worth of liquidity to an Across pool and the pool generates $1,000 in fees over a year, you would receive a proportional share of those fees based on your contribution to the pool's liquidity.

06Comparing Across Protocol to Other Cross-Chain Bridges

Across Protocol is not the only cross-chain bridge solution available. Several other protocols offer similar functionality, each with its own set of advantages and disadvantages. Popular alternatives include Hop Protocol, Celer Network, and Stargate Finance. Understanding the differences between these bridges is crucial for choosing the best option for your specific needs.

Hop Protocol focuses on fast and cheap transfers between different Layer-2 networks, primarily within the Ethereum ecosystem. Celer Network offers a more generalized cross-chain messaging protocol, enabling a wider range of applications beyond simple asset transfers. Stargate Finance is designed for stablecoin transfers and utilizes a unified liquidity pool across multiple chains.

Across Protocol distinguishes itself through its capital efficiency, security model (bonded relayers), and focus on bridging between Layer-2 and Layer-1 networks. While Hop Protocol might be faster for certain Layer-2 to Layer-2 transfers, Across Protocol often offers lower fees for bridging to Ethereum. Stargate Finance is ideal for stablecoins, but Across Protocol supports a broader range of assets. Ultimately, the best choice depends on your specific requirements, such as the asset you want to bridge, the destination network, and your risk tolerance.
