Ever felt stuck with your crypto on one blockchain while better opportunities lie elsewhere? Whether you're moving USDC from ethereum to Base for higher yields or exploring multi-chain DeFi, this guide breaks down how to bridge your assets seamlessly—using Relay Bridge as a case study. We’ll cover prerequisites, fees, and pro tips to avoid common pitfalls.

Why Migrate Cryptos Across Blockchains?

Blockchain bridges unlock interoperability, letting you tap into faster transactions, lower fees, or niche DeFi protocols. For instance, Ethereum users often bridge to Layer 2s like Base to dodge mainnet gas fees while accessing identical assets. But before you jump:

• Wallet compatibility: Ensure your wallet (e.g., MetaMask) supports the destination chain.
• Gas fees: You’ll need native tokens (like ETH on Base) to pay for transactions post-migration.

Step 1: Prepare for the Bridge

Let’s say you’re bridging USDC from Ethereum to Base:

1. Fund your wallet: Hold enough ETH on Ethereum to cover bridge fees.
2. Bridge ETH first: Since Base uses ETH for gas, transfer a small amount as a "seed fund."

Step 2: Execute the Bridge via Relay

Relay simplifies cross-chain swaps with a unified interface. Here’s how:

1. Visit https://www.relay.link/bridge and connect your wallet.
2. Select Ethereum as the source chain and USDC as the asset.
3. Choose Base as the destination and confirm the receiving token (USDC or a swapped asset).
4. Enter the amount and review fees, which typically include:
   • Bridge fee (0.1–0.3%)
   • Estimated slippage (e.g., 1 USDC → 0.999 USDC)

: Relay lets you swap mid-bridge. Need USDT instead of USDC on Base? Adjust the output token!
