Token bridging on Trezor Wallet transfers crypto assets across blockchains through three integrated pathways — THORChain, Invity’s partner network, and third-party EVM bridge dApps via MetaMask.
Private keys remain inside the hardware device throughout every bridge operation — Trezor Suite never exposes the seed phrase to any bridge protocol or external service. This guide covers every provider, mechanism, and safety step.
| Provider | Chains Supported | Mechanism | Wrapped Asset | Best For |
|---|---|---|---|---|
| THORChain | BTC, ETH, SOL, AVAX, BNB + others | Native liquidity pools | Never | Native BTC to ETH or SOL without wrapping |
| Invity (ChangeNow / Changelly) | 300+ assets, 40+ chains | Custodial atomic swap | Optional | Quickest altcoin cross-chain swaps |
| MetaMask + Li.Fi / Across | ETH, Arbitrum, Base, BNB, Polygon, Optimism | Aggregated EVM bridge | Optional | Cheapest EVM-to-EVM route |
| MetaMask + Stargate / Hop | 10+ EVM chains | Liquidity pool bridging | No (native USDC/USDT) | Stablecoin bridging across EVM chains |
Token bridging moves a crypto asset from one blockchain to an equivalent or different asset on a separate blockchain — for example, BTC on Bitcoin to ETH on Ethereum, or USDC on Ethereum to USDC on Arbitrum. Trezor Suite supports native cross-chain bridging via THORChain and cross-chain swaps via Invity partners — no external website is required for these routes.
Third-party EVM bridges like Li.Fi, Across, Stargate, and Hop Protocol work with Trezor when connected through MetaMask — Trezor signs every bridge transaction on-device without exposing private keys to the browser.
| Operation | Asset Changes | Chain Changes | Example |
|---|---|---|---|
| Swap | Yes | Same chain | ETH to USDC on Ethereum |
| Bridge | No | Different chain | ETH on Ethereum to ETH on Arbitrum |
| Cross-chain swap | Yes | Yes | BTC on Bitcoin to ETH on Ethereum |
Trezor Suite’s Swap tab handles both same-chain swaps and cross-chain swaps via Invity — the interface does not distinguish between them explicitly. THORChain performs true cross-chain swaps using native liquidity pools, moving BTC directly into ETH on Ethereum without any wrapped intermediate token.
| Mechanism | Destination Token | Trust Assumption | Risk |
|---|---|---|---|
| Lock and Mint | Wrapped (e.g. wBTC) | Bridge smart contract security | Exploit empties lock contract — wrapped token loses peg |
| Burn and Mint (CCTP) | Native (USDC) | Issuer attestation (Circle) | Attestation delay during congestion |
| Native Liquidity Pool (THORChain) | Native (BTC, ETH) | Validator quorum (67 of 100 nodes) | Slip fee on large trades; 60-min BTC settlement |
Historical Exploits: Lock-and-Mint bridges carry the highest smart contract risk — the $625M Ronin and $320M Wormhole exploits both targeted locked asset contracts in 2022. THORChain eliminates wrapped token peg risk but introduces validator quorum assumptions.
Yes. Trezor Suite integrates THORChain directly inside the Swap tab — BTC, ETH, SOL, AVAX, BNB, and DOGE are supported as native source and destination assets. No wrapped BTC is created at any stage, and Bitcoin finality requires approximately 60 minutes for full settlement.
Invity aggregates swap offers from ChangeNow, Changelly, CoinSwitch, and Binance Connect inside Trezor Suite — over 300 assets across 40+ chains are supported. Invity routes are custodial during the swap window, but require no additional wallet connection since the entire flow happens inside Trezor Suite.
Trezor connects to MetaMask as a hardware signer — MetaMask handles wallet connectivity while Trezor signs every transaction on-device. Li.Fi, Across, Stargate, Hop Protocol, and Bungee are all accessible. Every bridge transaction requires physical button confirmation on the Trezor device.
Connect Trezor via USB and unlock with PIN, then open Trezor Suite.
Go to Trade then Swap — select BTC as source and ETH, SOL, AVAX, or BNB as destination.
Enter the amount, review the slip fee, select the destination address, and click Confirm swap.
Verify the Bitcoin send address and amount on the Trezor device screen and press confirm.
Wait approximately 60 minutes for full THORChain settlement — ETH arrives after finality.
Warning: Do not close Trezor Suite or disconnect the device during the swap window. Always verify the destination address on the Trezor hardware screen — never rely solely on the software display.
| Risk | Mitigation in Trezor Wallet |
|---|---|
| Bridge smart contract exploit | Use THORChain native pools or audited bridges like Across and Stargate only |
| Address substitution / clipboard attack | Always verify destination address on Trezor hardware screen |
| MEV and sandwich attacks | Li.Fi and Across include MEV protection |
| Wrong chain confirmation | Trezor Suite displays chain ID for every transaction |
| Invity partner failure | Funds returned to source address within 24 hours |
| Wrapped token peg loss | Use THORChain or canonical USDC bridges to avoid wrapped exposure |
| Criterion | THORChain | Invity | MetaMask + EVM Bridge |
|---|---|---|---|
| Supports BTC | Yes — native | Yes — custodial | No |
| EVM chain coverage | Limited | 40+ chains | Best |
| Custody during bridge | Non-custodial | Custodial (brief) | Non-custodial |
| Settlement speed | 60 min (BTC) | 5–30 min | 2–20 min |
| Fee model | Slip fee 0.1–3% | Provider spread | Bridge fee + gas |
Open Trezor Suite then go to Trade then Swap. Select your source and destination assets — Trezor Suite routes through THORChain or Invity partners. Confirm on the hardware device screen. For EVM bridges, connect Trezor to MetaMask and use Li.Fi, Across, or Stargate.
Yes. THORChain inside Trezor Suite bridges Bitcoin natively — no wrapped BTC is created. BTC enters the THORChain pool and native ETH, SOL, AVAX, or BNB exits on the destination chain. Settlement takes approximately 60 minutes.
THORChain for native cross-chain swaps, Invity partners for custodial swaps across 300+ assets, and MetaMask connecting to Li.Fi, Across, and Stargate for EVM-to-EVM bridging.
Trezor hardware protects private keys throughout every bridge transaction. THORChain and Invity integrations are open-source and audited. Primary risks are third-party bridge protocol risk and user error — always verify transaction details on the hardware screen.
THORChain BTC bridge takes about 60 minutes; ETH or SOL routes take 10–20 minutes. Invity cross-chain swaps take 5–30 minutes. EVM bridges via MetaMask take 2–20 minutes, and Stargate stablecoin bridges take 1–5 minutes.
Trezor Suite charges no platform bridging fee. THORChain charges a slip fee of roughly 0.1–3%, Invity partners charge a provider spread, and EVM bridges charge protocol fees plus gas on both chains.
