Chain connectors integrate a Layer 1 blockchain and their networks into Gateway, enabling wallet access, node RPC interactions, and other support needed by DEXs supported by Gateway. Each connector is customized for a particular blockchain's idiosyncrasies to enable this level of standardization, so they may should ideally have a maintainer, whose role is to ensure consistent performance by fixing bugs, incorporating API updates, and other ongoing work.
Here are the current chain connectors in the codebase:
|Ethereum||EVM||🥇 Gold||Hummingbot Foundation|
|Avalanche||EVM||🥈 Silver||Hummingbot Foundation|
|BNB Chain||EVM||🥈 Silver||Hummingbot Foundation|
|Polygon||EVM||🥈 Silver||Hummingbot Foundation|
|XDC Chain||Non-EVM||🥉 Bronze|
