Cross-Chain Bridges: How to Move Crypto Between Blockchains
Crypto lives on different blockchains that cannot natively communicate. Bridges solve this. Here is how they work, which are safe, and how to use them.
Bitcoin lives on the Bitcoin blockchain. USDC can exist on Ethereum, Solana, Tron, and 10 other chains. Moving assets between blockchains requires a bridge — a protocol that locks assets on one chain and issues equivalent representations on another. Bridges are essential infrastructure for the multi-chain DeFi ecosystem of 2026.
How Bridges Work
- Lock-and-mint: send ETH to Ethereum bridge contract, receive wETH on another chain
- Burn-and-mint: burn token on source chain, mint new tokens on destination chain
- Liquidity networks: bridge matches you with someone doing the opposite transfer — no locking/minting
- Atomic swaps: trustless peer-to-peer cross-chain exchange using hash time-locked contracts
- Speed: varies from 1 minute (Arbitrum native bridge) to 7 days (Optimism official bridge)
Bridge Risks and Safety
- Bridge hacks are the single largest source of DeFi losses — $2B+ stolen from bridges historically
- Ronin Bridge (Axie Infinity): $625M stolen in 2022 — validator key compromise
- Wormhole: $320M exploit in 2022 — smart contract bug
- Safer bridges: those with multiple independent security audits, multisig governance, and established track records
- Steyble uses only audited bridge integrations — routes cross-chain swaps via LayerZero, Axelar, and native bridges
Using Bridges via Steyble
Steyble's cross-chain swap feature handles bridge complexity automatically. Select your source chain, destination chain, and amount — Steyble routes the transfer via the safest available bridge for that specific corridor. You do not need to interact with bridge interfaces directly. The swap preview shows the expected amount on the destination chain, estimated time, and bridge used.
