Onyx Bridge moves assets between EVM chains and Gonka. Each transfer includes a 0.3% bridge fee to cover gas costs and ongoing bridge operations.
Flow
1
Initiate on EVM
You send assets to the Onyx bridge smart contract on Ethereum, BSC, or Arbitrum.
2
Normalization to axlUSDC (when required)
If you send USDC or USDT on Ethereum, the transfer is routed directly through Axelar GMP.
For other supported tokens or source chains, the bridge converts the asset to axlUSDC (via PancakeSwap when applicable) and then routes it through Axelar GMP.
3
Delivery to Neutron via Axelar
Axelar GMP delivers the funds and the cross-chain message to the bridge contract on Neutron.
4
Final hop to Gonka via IBC
After funds arrive on Neutron, a trustless relayer automatically triggers an IBC transfer from Neutron → Gonka. No manual steps are required.
5
Funds available on Gonka
Your funds arrive on Gonka as axlUSDC, ready to swap, provide liquidity, or bridge again.
Notes
The bridge uses axlUSDC as the settlement asset for transfers into the Gonka ecosystem.
