Axelar supports the cross-chain bridging of four assets that were previously stranded on Binance due to the sunsetting of Binance’s BEP3 Bridge.

BEP3 allowed atomic swaps between blockchains, including Kava Chain and Binance Chain. BEP3-bridged assets on Kava Chain are currently backed by assets on Binance Beacon Chain. These backing assets were migrated to Binance Smart Chain around April 30.

Following the migration, the Kava community selected Axelar to bridge away any remaining assets that were stranded after the migration. Using various Axelar services, users are able to bridge BEP3 assets to Binance Smart Chain for BEP20 assets.

Four assets are affected: BNB, BTCB, BUSD and XRPB.

• BTCB and XRPB are cross-chain enabled via Interchain Token Service (ITS). They can be moved cross-chain via the ITS portal at the following addresses:
  • https://interchain.axelar.dev/kava/0x94FC70EF7791EE857A1f420B9A471a55F32382be
  • https://interchain.axelar.dev/kava/0x8e20A0a1B4664D1ae5d18cc48bA6FAD4d9569406
• BNB and BUSD are supported for bridging by Squid at app.squidrouter.com.
