How to bridge tokens to Arbitrum
Tokens can be bridged to Arbitrum on a variety of platforms. In this guide, we will explain how to use the official bridge and random multi-chain bridge.
Official Arbitrum bridge (Ethereum to Arbitrum)

1. Connect your wallet (Make sure you are on Ethereum main-net) 2. Enter the amount of ETH you want to add on Arbitrum and click “Move funds to Arbitrum One.” 3. The next step is to confirm the transaction in your wallet. Arbitrum's lower gas fees will apply despite this transaction being executed on layer 1. 4. Once you're happy with the amount, tap “Confirm.” 5. On the next page, the transaction will appear as "pending". 6. ETH is now available on Arbitrum and you can send and receive it.
Random multi-chain bridges (Multi-chain to Arbitrum)
For the purposes of this guide, we will use the LI.FI and Synapse protocol bridges since they offer a wide range of options for bridging funds from other networks to Arbitrum.
B/ https://transferto.xyz/swap
1.Click 'Connect your wallet' and approve
2. Select the network and token you wish to bridge, and then choose Arbitrum One and ETH (since GAS on Arbitrum is payed in ETH). Enter the amount you want to bridge and click 'Review swap'. 3. Click 'Start swap' 4. Click 'Confirm' to grant access to your funds 5. In the next popup, click 'Confirm' (you must have enough GAS tokens on the network you are bridging from in order to complete the transaction) 6. Within a few minutes of confirming the transaction, your funds should appear on Arbitrum. C/ Synapse protocol bridge
1. Select the network that you wish to transfer funds out of using the "From" dropdown menu (if necessary, accept the request in your wallet to switch networks to that chain) 2. Select the assets that you wish to bridge from the dropdown menu to the right of the input field (stablecoins, ETH, or SYN, plus an expanding list of tokens from partnerships). 3. Select the destination chain from the "To" dropdown menu. 4. Input the amount that you would like to transfer into the number field 5. Make sure that the amount you will be receiving appears correct, and click "Approve Token" to grant Synapse approval to spend the stablecoin you are swappingNote: you will receive the indicated amount of the native token when bridging to a non-Ethereum chain, enough to allow you to make 1-2 swaps upon arrival. 6. Click "Bridge Token" after the approval has been confirmed to bridge your funds.
