Frequently Asked Questions

Crypto bridging (cross-chain bridging) moves tokens between blockchains so you can use assets across networks. In thirdweb Bridge, connect your wallet, choose the source token/network and destination token/network, review the route and price, then confirm. Assets arrive after finality, often under ~10 seconds on fast routes, though timing depends on networks and congestion.

Bridge smart contracts lock or burn tokens on the source chain and mint or release equivalents on the destination via verified cross-chain providers. thirdweb Bridge automatically finds the fastest, lowest-cost route and may use different mechanisms based on networks and liquidity. Arrival can range from seconds to minutes depending on finality; many routes complete in ~10 seconds

A crypto swap exchanges one token for another via a DEX or aggregator. thirdweb Bridge lets you bridge + swap in one step. For example, ETH on Ethereum to USDC on Base, by selecting your start and end tokens/networks and confirming.

Use thirdweb Bridge to convert assets you hold into USDC or USDT on your chosen network: select your current token/network, pick the stablecoin (USDC, USDT, etc) on the destination, and confirm. You can also buy stablecoins with fiat in the Buy flow and bridge if needed. Always verify official token contract addresses.

Costs include gas on each chain, bridge/liquidity provider fees, and any DEX swap fees or price impact. thirdweb Bridge compares routes and selects the best price route. Save by using lower-gas times or combining bridge + swap in one flow.
