As the DeFi ecosystem continues to expand across multiple blockchains, Web3 users now require fast, secure, and decentralized ways to move assets between networks. Whether you're staking on Ethereum, farming on Arbitrum, collecting NFTs on Solana, or exploring the latest protocols on Base and Sui — multichain agility is essential.
portal bridge is the solution: a secure, non-custodial, and cross-chain bridge built on Wormhole, enabling seamless crypto transfers across 20+ blockchains. In this guide, we’ll walk through everything you need to know about using portal bridge in 2025 — and why it's become indispensable for any serious Web3 user.
What is portal bridge?
portal bridge is a decentralized cross-chain bridge that allows users to transfer crypto assets (including tokens, NFTs, and governance assets) between major blockchains. Built on the Wormhole protocol, portal bridge locks assets on the source chain and mints their equivalent on the destination chain using verifiable cross-chain messages known as VAAs (Verifiable Action Approvals).
Unlike centralized bridges or CEX withdrawals, portal bridge is non-custodial — meaning you never give up control of your private keys or funds.
