How to Transfer Tokens Across Chains Using the Best Crypto Bridges

Example: Use Synapse Protocol to transfer USDC from Ethereum to Arbitrum

Step 1: Connect Your Wallet

Access the Synapse Protocol website.

Click “Connect Wallet” and select a wallet (e.g., MetaMask).
Ensure your wallet is on Ethereum.

Step 2: Choose the Networks

Select Ethereum in the “From” field.

Select Arbitrum One in the “To” field.
This defines the direction of your bridge transfer.

Step 3: Select the Token

Select USDC (or another supported token).

Enter how much you want to transfer.
Your cash-out, and the gas fees will be estimated.

Step 4: Review Bridge Details

Re-verify the-
- Source & destination chains
- Amount of token
- Estimated time and fee
Click “Approve” to allow the bridge use your token.
Finalise the operation on your wallet.

Step 5: Execute the Transfer

After you approve it, select “Bridge Token” or “Swap”.
Double check the transaction in your wallet.
Take a minute to reset (usually under 5 minutes for Arbitrum).

Step 6: Destination Network Switch

Upon completing the transaction, switch your network from Arbitrum to your wallet.
You’ll now see the USDC tokens in the Arbitrum wallet.

Why You Need Crypto Bridges

Interoperability Between Blockchains

Crypto bridges are essential for enabling the transfer of tokens, assets, and information between Ethereum, BNB Chain, Avalanche, and Solana. By connecting multiple ecosystems, various blockchain networks become accessible without barriers.

Better DeFi Opportunities

Moving assets across different networks opens the door to various platforms for yield farming, staking, and lending, further enhancing the potential to earn in DeFi.

Reduced Transaction Costs

Users needing to transfer currencies from Ethereum, a high-fee blockchain, to cheaper options like Arbitrum or Polygon, will find their transaction costs considerably lowered.

Improved Liquidity and Functionality

Moving tokens between chains offers wider functionality of a token and enhanced liquidity, which benefits decentralized exchanges (DEXs) and distributed applications (dApps).

Support for Multichain Strategies

Crypto investors use multiple blockchains to manage their risks and maximize their returns. Bridges facilitate quick and easy asset transfers, making multi-blockchain strategies more practical.

Access To New Opportunities

New projects are regularly developed on various chains. Bridges provide the tools to participate early, receive airdrops, and engage with different DeFi or NFT technologies.

Security Tips for Using Crypto Bridges

Verify the Official Website or URL

Fake and phishing websites exist, and they can steal your funds in a matter of seconds! Always verify a bridge’s URL before wallet connection. For your safety, bookmark the official bridge site.

Use Audited and Reputable Bridges

Use bridges that have had extensive community reputation and that have completed third-party security audits. Steer clear of new and unverified platforms with little to no transparency.

Start with Small Test Transactions

To check if the bridge operates properly and your test funds arrive successfully on the destination chain, try a small test transaction first before larger transfers.

Check Supported Networks and Tokens

Transfer only tokens and networks that are officially supported by the bridge. Sending unsupported assets can result in the permanent loss of those assets.

Use a Hardware Wallet for Extra Protection

Bridging larger amounts requires a hardware wallet like Ledger or Trezor to keep your private keys safe and secure from digital theft.

Avoid Suspicious Airdrops or Promises

Be wary of social media promotions or offers that promise “bridge bonuses”. Scammers often impersonate high traffic bridge protocols to lure users into wallet connection.

Common Mistakes to Avoid

Using Fake or Unverified Bridges

Scammers are known to closely imitate interfaces of well-known bridges. Always check the official website and social media accounts to confirm safe connections before wallet connections to prevent fund loss.

Sending Unsupported Tokens or Chains

Bridges are programmed to integrate a range of chains and tokens. You are at risk of losing unsupported tokens or chains permanently. Always confirm the range to prevent such loss.

Ignoring Gas Fees and Network Congestion

Gas prices are determined by each blockchain and they can rapidly fluctuate according to network activity. Poor estimation can lead to transaction failure especially during high congestion periods.

Skipping the Approval Step

Approval of some tokens is a pre-requisite for swapping on certain bridges. Any failure to approve will result in transaction errors or incomplete swaps, prompting the need for rude repeating.

Not Verifying the Destination Wallet Network

Wallet recipients need to be informed of the network destination to be made compatible with any tokens. Otherwise, tokens sent to an incompatible wallet will be frozen in a digital purgatory.

Transferring Large Amounts Without Testing

In order to guarantee the correct configuration and bridge route, commence transactions with the bare minimum to eliminate the risk of large sums.

Ignoring Security Warnings or Audits

Unverified or poorly documented bridges pose a high risk. Don’t use them, no matter how low the fees or how quick the transfers.

Forgetting to Switch Networks After Bridging

After a successful bridge, you may still have to manually switch your wallet network (e.g. Ethereum to Polygon) to see and use the tokens.
