How to bridge crypto between chains

This guide covers how to bridge crypto between chains step by step using XAUConnect. You keep custody of your wallet keys throughout; the platform aggregates quotes and builds transactions for you to approve.

XAUConnect does not require account registration to obtain quotes — connect a wallet only when you are ready to trade.

Before you start

Decentralized swaps settle against on-chain pools, not a centralized order book. Prices move every block as other traders execute, which is why quotes expire and should be refreshed before signing. Pick the network where your tokens already live before quoting. Moving assets between chains requires a separate bridge flow. Cross-chain moves add bridge time and smart-contract risk on top of ordinary swap mechanics. Use dedicated cross-chain mode to see each step and estimated arrival time.

Step-by-step

1. Select network and tokens in the swap widget 2. Connect a compatible wallet 3. Enter amount and wait for quotes to refresh 4. Compare routes by minimum received 5. Set slippage appropriate to pool depth 6. Approve token spending once if required 7. Confirm the swap and verify receipt on the explorer If quotes fail, reduce size slightly, nudge slippage up incrementally, or retry after network congestion eases.

Using XAUConnect

XAUConnect supports spot swaps and cross-chain routes with wallet-signed execution. Quotes refresh as pool reserves change — if you wait more than a minute between preview and signature, request a fresh quote. Switch networks from the chain selector without leaving the app. Each network uses its own gas token and block explorer.

Execution pitfalls

Copying token addresses from social media without verifying every character on the explorer. When in doubt, run a small test trade before committing size.

Fees, slippage, and price impact

Three separate costs affect every swap: the platform or routing fee (shown in the quote card), network gas paid to validators, and price impact from moving the pool curve with your trade size. Slippage tolerance tells the contract how far the price may move while your transaction confirms. Start conservatively on unfamiliar pairs — widening slippage invites worse fills on public mempools. Gas varies widely by network — Ethereum mainnet costs more than most L2s, while Solana uses priority fees during congested periods.

How to get the best fill

Compare minimum received across routes, not just the displayed exchange rate. On large trades, split into two transactions if price impact exceeds your comfort level. Stablecoin pairs (USDC, USDT, DAI) usually offer the tightest spreads. Volatile altcoins may route through ETH or USDC hops — the quote card lists each hop explicitly. If a quote fails simulation, reduce trade size first, then adjust slippage incrementally rather than setting it to maximum immediately.

Frequently asked questions

How do I how to bridge crypto between chains?

Yes. Connect your wallet, enter tokens and amount, pick a route, and confirm. Fees and minimum received are shown before you sign. Compare at least two routes when the trade size is meaningful.

Do I need an account or KYC?

No. Connect a wallet only when you want to execute a swap. XAUConnect never holds your funds — each step requires a wallet signature.

Which networks are supported?

Ethereum, BNB Chain, Polygon, Arbitrum, Base, Avalanche, and Solana. Re-quote if more than a minute passes before you sign; pool prices move continuously.

Is this financial advice?

No. This is educational content about decentralized trading mechanics. Start with a small test amount when trying a new token or route for the first time.
