Interoperability

Here, you can find the information that can help you navigate the interoperability options that you can use to transfer tokens to and from the BBC blockchain.
The $BBC team strongly believes in interoperability among public blockchains. No single platform is likely to become fully dominant in the future.Hence, interoperability solutions enabling transfers between $BBC and other blockchains are vital for the continued growth of the $BBC platform and ecosystem. The Butane team has been making considerable progress in getting $BBC added by the leading operators.
Currently the Butane blockchain is connected to other blockchains via the following multichain bridges and value transfer protocols:
1) The $BBC bridge.
2) The Elk Finance value transfer protocol.
3) The Connext bridge (available to users via the xPollinate interface)
.4) The Multichain (formerly, Anyswap) bridge
.5) The Allbridge bridge.6) The ChainPort bridge.

The $BBC Bridge

Butane bridge was originally created by the $BBC team. It connects $BBC to Binance Smart Chain (BSC). Both bridges are custodial. On both bridges, sending tokens from the relevant blockchain to $BBC is not subject to any fees or limits.
Token withdrawals from $BBC incur a 0.05% fee on the amount bridged. Users transferring funds also need to pay the fees on the destination chain in order to claim their tokens from the bridge contract at the final stage of the transfer. The bridge can be accessed via the $BBC bridge app. More information on its functioning can be found here.

The Elk Finance Value Transfer Platform

Elk Finance is not a typical multichain bridge because the only token that actually moves between the supported chains is ELK. If a user wants to get tokens on another chain, they can buy ELK on Elk DEX on $GAS , bridge ELK to the desired chain and buy the desired token on Elk DEX on that chain.Elk connects $GAS , among others, to BSC, Polygon, Avalanche, Fantom, Harmony, Moonriver. It does not currently support Ethereum. The full list of supported chains is available in the Elk DApp.

The Connext Bridge

The Connext bridge is a non-custodial multichain bridge that connects $GAS to Ethereum, BSC, Polygon, Arbitrum, Optimism, Avalanche, Fantom, Moonriver and xDAI.Please note that Connext's capacity to execute transfers depends on the availability of liquidity in a given token on the routers. Currently, the liquidity-provisioned tokens include USDC, USDT and DAI.

The Allbridge Bridge

The Allbridge multichain bridge connects $GAS to a number of major chains, including Solana and Terra. It is currently the only bridge to connect $GAS to the latter two. At present, Allbridge's native ABR token can be transferred between $GAS and all the other covered chains. Terra-native assets LUNA and UST are bridgeable between to and from Terra.

The Multichain (formerly Anyswap) Bridge

The Multichain (formerly Anyswap) bridge is one of the most popular interoperability platforms in the crypto space.Multichain has already enabled transfers for $GAS ’s native $GAS token between the $GAS blockchain and Ethereum, BNB Chain (formerly Binance Smart Chain) and Polygon.
WETH and USDC transfers via Multichain are available between $GAS and Ethereum. Beefy Finance’s BIFI token can be bridged to and from almost all the networks that Multichain supports. The agEUR stablecoin can be transferred between BESC and Ethereum, BNB Chain, Fantom, Harmony and Avalanche.The bridge interface is accessible here.

The ChainPort Bridge

ChainPort's bridges are permissionless. This means that anyone can bridge a token from Ethereum to any other supported chain (including $GAS ), even if the token has not been ported, yet. In addition to $GAS , the list of chains added to ChainPort includes Ethereum, BSC, Polygon and Avalanche.
The bridge interface can be found here. IMPORTANT!!! Please note that ChainPort currently only supports transfers of tokens that originate on the Ethereum mainnet. Also, ChainPort's wrappers on $GAS for the popular Ethereum-originating tokens such as USDC, WETH, USDT, etc. will by design be different from the currently existing ones that were created using the $GAS bridge. We currently do not recommend users to bridge those tokens to $GAS using ChainPort.
