Using the Sovryn Cross-Chain Bridge

The Sovryn Cross-Chain Bridge allows easy and permissionless transfers of your tokens from one chain/sidechain to another. There are currently 3 main chains/sidechains included in the Cross-Chain Bridge: RSK, Ethereum, and Binance Smart Chain.
The Sovryn Cross-Chain Bridge can be accessed here.


Currently, bridging between Ethereum facilitates the transfer of 3 stablecoins (DAI, USDC, USDT) and ETH (Native ETH token) from ETH-mainnet to the Sovryn ecosystem on RSK-mainnet.
All enabled bridge tokens will be propagated to 2 aggregators according to a category on the RSK mainnet:
  • ETHs aggregator - receive ETH
  • XUSD aggregator - receive DAI, USDC, USDT
To bridge Ethereum from other blockchains, see Bridging ETH to Sovryn.

Binance Smart Chain (BSC)

Bridging between Binance (BSC) enables the transfer of 4 stable coins (DAI, USDC, BUSDT, BUSD), BNB (Native BSC token) and the Binance ETH pegged token from BSC-mainnet to the Sovryn ecosystem on RSK-mainnet.
All enabled bridge tokens will be propagated to 3 aggregators according to a category on RSK mainnet:
  • ETHs aggregator - receive ETH
  • XUSD aggregator - receive DAI, USDC, BUSDT, BUSD
  • BNB aggregator - receive BNB

Relevant Contract Addresses

When you use the Sovryn Cross-Chain Bridge to send assets from your address in either the Ethereum or BSC networks, you will receive the resulting tokens in your connected wallet, or the specific wallet address you designate as the receiver (where applicable).
If you want to see these tokens in your wallet, you may be required to add the token contract address to your wallet manually.
