PolygonBNB Smart Chain

Network-specific checks before a cross-chain transaction.

Polygon and BNB Smart Chain have separate network contexts. A cross-chain route must account for the source environment, destination environment and the mechanism used to transfer or represent the asset.

Route Intelligence

Source network

Polygon: Polygon provides an EVM-compatible environment with its own network balances and token representations.

Destination network

BNB Smart Chain: BNB Smart Chain is an EVM-compatible network with its own BEP-20 token representations.

Asset considerations

On the source side, Confirm that the token is held on Polygon and verify its contract before moving or swapping it. On the destination side, Verify BEP-20 contracts and distinguish legitimate assets from unsolicited tokens.

Fee considerations

Compare Polygon transaction costs with bridge and liquidity costs when consolidating small balances. On BNB Smart Chain, Network transaction costs are only one part of the route; compare the complete cost before moving small balances.

Before You Bridge

  • Source: confirm the asset is actually held on Polygon.
  • Destination: confirm the wallet and destination network.
  • Token: verify the exact asset representation rather than relying on ticker or logo.
  • Costs: compare gas, bridge fees, liquidity, price impact and the final received amount.
  • Security: Check network selection and contract addresses before signing, especially when an asset also exists on Ethereum. At the destination, Treat unexpected tokens and unfamiliar approvals cautiously and verify contracts before interacting.
Never use a seed phrase or private key to complete a bridge. A legitimate bridge flow should not require either.

Use the Live Bridge Tool

When a live route is available, open Dust Sweeper and review the current quote immediately before signing. Route availability, liquidity and network conditions can change.
