How to add the Polygon network to Trust Wallet? How to bridge assets?

Adding Polygon Network to Trust Wallet

1. Open the Trust Wallet application on your mobile device and ensure you are logged into your wallet.

2. Tap the wallet icon in the bottom navigation bar, then select the three-dot menu in the top-right corner.

3. Choose “Settings” and scroll down to “Networks”, then tap “Add Network”.

4. Select “Polygon” from the list of supported networks — Trust Wallet pre-configures the chain ID (137), RPC URL (https://polygon-rpc.com), and block explorer (https://polygonscan.com).

5. Confirm the network addition; the Polygon logo will appear next to your wallet balance once enabled.

6. To verify, toggle between Ethereum and Polygon in the network selector at the top of the wallet screen — assets on Polygon will display only when the network is active.

Importing Polygon-Based Tokens Manually

1. Navigate to the “Assets” tab and tap the “+” button in the top-right corner.

2. Select “Custom Token” and choose “Polygon” as the network.

3. Enter the contract address of the token — for example, USDC on Polygon is 0x2791bca1f2de4661ed88a30c99a7a9449aa84174.

4. Tap “Next”, then “Add Custom Token”; the token symbol, decimals, and name will auto-populate if the contract is verified on Polygonscan.

5. Once added, the token balance will appear under the Assets list when Polygon is selected as the active network.

6. Ensure the contract address matches the official deployment — unofficial or scam tokens often mimic legitimate ones with slight variations.

Using Polygon Bridge to Transfer Assets

1. Visit the official Polygon PoS Bridge at https://bridge.Polygon.technology using a browser connected to Trust Wallet via WalletConnect.

2. Connect your Trust Wallet by scanning the QR code or selecting it from the wallet list.

3. Select the asset you wish to bridge — ETH, MATIC, or ERC-20 tokens like USDT or DAI — and specify the amount.

4. Choose “Ethereum → Polygon” for depositing assets onto Polygon or “Polygon → Ethereum” for withdrawing.

5. Approve the transaction on Ethereum first — this requires ETH for gas and may take 5–20 minutes depending on network congestion.

6. After confirmation, the second step initiates on Polygon; finalization typically completes within 22–30 minutes for deposits and up to 3 hours for withdrawals.

Security Considerations During Bridging

1. Never enter your seed phrase or private key on any bridge interface — Trust Wallet never requests these details externally.

2. Double-check the URL: only use bridge.polygon.technology — avoid lookalike domains with typos or alternate TLDs.

3. Monitor pending transactions via Etherscan and Polygonscan using the transaction hash provided after each step.

4. Avoid bridging during high congestion on Ethereum — elevated gas fees increase costs and delay confirmations.

5. Confirm that the destination wallet address shown in Trust Wallet matches your intended receiving address before signing any transaction.

Frequently Asked Questions

Q: Why does my bridged MATIC not appear in Trust Wallet after finalization?Check whether Polygon is selected as the active network and verify the token was added manually if it’s not a native asset. Also confirm the transaction succeeded on Polygonscan.

Q: Can I bridge NFTs from Ethereum to Polygon using the official bridge?No — the Polygon PoS Bridge supports only fungible tokens and ETH. NFT bridging requires third-party tools like Orbiter Finance or specific NFT marketplace integrations.

Q: Is there a minimum amount required to bridge assets to Polygon?There is no protocol-enforced minimum, but gas fees on Ethereum may make very small transfers uneconomical. For MATIC deposits, amounts below 0.01 MATIC rarely justify the cost.

Q: What happens if I send ETH directly to a Polygon address?Etherum ETH sent to a Polygon address becomes irretrievable — ETH exists only on Ethereum mainnet. Only wrapped ETH (WETH) or bridged ETH should be used on Polygon.
