Gateway provides standardized access to multiple blockchain networks and DEX protocols. This page lists all currently supported chains and their associated DEX connectors.

​
EVM-Compatible Chains

Gateway supports the following EVM-compatible blockchain networks:

​
Ethereum

Ethereum Mainnet

Chain ID: 1

  • Uniswap (Router, AMM, CLMM)
  • SushiSwap (AMM)
  • Balancer (AMM)
  • Curve (AMM)
  • 0x Protocol (Router)

gateway connect ethereum

​
Polygon

Polygon (Matic)

Consensus: Proof of StakeSupported DEXs:
  • QuickSwap (AMM)
  • SushiSwap (AMM)
  • Uniswap V3 (CLMM)
Configuration: 
gateway connect polygon

​
BNB Smart Chain (BSC)

BNB Smart Chain

Chain ID: 56
Native Token: BNB
Block Time: ~3 seconds
Consensus: Proof of Staked AuthoritySupported DEXs:
  • PancakeSwap (AMM)
Configuration: 
gateway connect binance-smart-chain

​
Avalanche

Avalanche C-Chain

Chain ID: 43114
Native Token: AVAX
Block Time: ~2 seconds
Consensus: Avalanche ConsensusSupported DEXs:
  • Trader Joe (AMM)
  • SushiSwap (AMM)
Configuration: 
gateway connect avalanche

​
Arbitrum

Arbitrum One

Chain ID: 42161
Native Token: ETH
Block Time: ~0.25 seconds
Type: Ethereum Layer 2 (Optimistic Rollup)Supported DEXs:
  • Uniswap V3 (CLMM)
  • SushiSwap (AMM)
Configuration: 
gateway connect arbitrum

​
Optimism

Optimism

Chain ID: 10
Native Token: ETH
Block Time: ~2 seconds
Type: Ethereum Layer 2 (Optimistic Rollup)Supported DEXs:
  • Uniswap V3 (CLMM)
Configuration: 
gateway connect optimism

​
Non-EVM Chains

​
Solana

Solana

Native Token: SOL
Block Time: ~400ms
Consensus: Proof of History + Proof of Stake
TPS: ~65,000Supported DEXs:
  • Jupiter (Router)
  • Raydium (AMM, CLMM)
  • Meteora (CLMM)
Configuration: 
gateway connect solana
Solana uses a different wallet format than EVM chains. You’ll need a Solana-specific private key when connecting.

​
DEX Protocols by Type

​
Router DEXs (DEX Aggregators)

Router protocols find optimal swap routes across multiple liquidity sources:

Uniswap Router

Chains: Ethereum, Polygon, Arbitrum, Optimism
Type: Router, AMM, CLMM
Connector ID: uniswapSupports V2 (AMM) and V3 (CLMM) protocols with intelligent routing.

0x Protocol

Chains: Ethereum, Polygon, BSC, Avalanche
Type: Router
Connector ID: 0xAggregates liquidity from multiple DEXs and market makers.

Jupiter

Chains: Solana
Type: Router
Connector ID: jupiterLeading DEX aggregator on Solana with optimal route finding.

​
AMM DEXs (Constant Product)

Traditional automated market makers using x*y=k formula:

SushiSwap

Chains: Ethereum, Polygon, Arbitrum, Avalanche
Type: AMM
Connector ID: sushiswap

PancakeSwap

Chains: BNB Smart Chain
Type: AMM
Connector ID: pancakeswap

Trader Joe

Chains: Avalanche
Type: AMM
Connector ID: traderjoe

QuickSwap

Chains: Polygon
Type: AMM
Connector ID: quickswap

Balancer

Chains: Ethereum, Polygon, Arbitrum
Type: AMM (Weighted Pools)
Connector ID: balancer

Curve

Chains: Ethereum, Polygon, Arbitrum
Type: AMM (Stableswap)
Connector ID: curve

Raydium AMM

Chains: Solana
Type: AMM, CLMM
Connector ID: raydium

​
CLMM DEXs (Concentrated Liquidity)

Concentrated liquidity market makers with custom price ranges:

Uniswap V3

Chains: Ethereum, Polygon, Arbitrum, Optimism
Type: CLMM
Connector ID: uniswapCapital-efficient liquidity provision with custom price ranges.

Raydium CLMM

Chains: Solana
Type: CLMM
Connector ID: raydiumConcentrated liquidity pools on Solana.

Meteora

Chains: Solana
Type: CLMM
Connector ID: meteoraDynamic liquidity pools on Solana.

Chain Comparison

ChainNative TokenBlock TimeAvg Gas CostDEX CountBest For
EthereumETH~12sHigh5High liquidity, established DeFi
PolygonMATIC~2sVery Low3Low-cost trading, high frequency
BSCBNB~3sLow1Alternative to Ethereum
AvalancheAVAX~2sLow2Fast finality, low fees
ArbitrumETH~0.25sMedium2Ethereum L2, lower fees
OptimismETH~2sMedium1Ethereum L2, lower fees
SolanaSOL~0.4sVery Low3Ultra-fast, high throughput
For high-frequency strategies, consider Polygon or Solana due to their low transaction costs and fast block times.

​
Testing Networks

Gateway also supports testnet networks for development:
  • Goerli (deprecated, use Sepolia)
  • Sepolia (recommended)
  • Holesky (for validators)
gateway connect ethereum --network sepolia
Testnet tokens have no real value. Use testnets only for development and testing purposes.

​
Adding New Chains

Gateway is designed to be extensible. To request support for a new chain or DEX:
1

Check Existing Proposals

Review Github issues for existing requests.
2

Submit a Proposal

Create a New Connector Proposal following the Governance process.
3

Community Vote

Proposals are voted on by HBOT token holders.
4

Development

Approved proposals can be developed by the community or core team.
You will need HBOT tokens in your Ethereum wallet to submit a proposal. See Proposals for more information.

​
Chain-Specific Considerations

Challenge: Gas fees can be very high during network congestion.Recommendations:
  • Monitor gas prices using tools like Etherscan Gas Tracker
  • Trade during off-peak hours (weekends, late night UTC)
  • Consider using Layer 2 solutions (Arbitrum, Optimism) instead
  • Use higher trade sizes to amortize gas costs
Challenge: Public RPC endpoints may have rate limits.Recommendations:
  • Use dedicated RPC providers (Alchemy, Infura, QuickNode)
  • Monitor RPC endpoint health
  • Have backup RPC endpoints configured
Challenge: More centralized than other chains.Recommendations:
  • Be aware of potential network governance decisions
  • Use BNB for gas fees (cannot use other tokens)
  • Monitor official BNB Chain announcements
Challenge: Solana uses different key format than EVM chains.Recommendations:
  • Use Solana-specific wallet tools to export private keys
  • Cannot reuse the same wallet address from Ethereum
  • Be aware of different transaction structure and rent requirements
Challenge: Need to bridge assets from Ethereum mainnet.Recommendations:
  • Use official bridges (Arbitrum Bridge, Optimism Gateway)
  • Account for bridge time (usually 1-7 days for withdrawals)
  • Keep some native ETH on L2 for gas fees
