Specifying Chains
When sending prompts, you can specify the chain:
"swap $10 of USDC to ETH on base"
"buy $5 of BONK on solana"
"buy $20 of MATIC on polygon"
If no chain is specified, Bankr will:
- Use the chain where your balance is highest
- Default to Base for EVM operations
- Default to Solana for SOL-related operations
Cross-Chain Operations
Bankr supports cross-chain swaps between EVM chains using bridge aggregators:
"swap $50 USDC from polygon to ETH on base"
Cross-chain operations between EVM and Solana are not currently supported.
