    Allbridge is a simple, modern, and reliable way to transfer assets between different networks. It is a bridge between both EVM (Like Ethereum, Polygon, BSC) and non-EVM compatible (like Solana, Terra) blockchains, that aims to cover L2 (like Arbitrum, Optimism). Cross-chain transfers are done a single bridgeable token, ABR. From time to time, there appears some price discrepancies among different blockchains. Your bot is expected to take advantage of that. In other words, it buys low, sells high on other blockchain. To transfer USDC/USDT the other way around your bot can use a low-fee bridge such as multichain. Bonus: Your bot can reduce bridging fees before attempting to execute the cross-chain transfer by staking ABR. This will allow the bot to even make use of smaller price di...
