Sponsored gas covers up to 10 transactions and $3 of gas per wallet per 24 hours; past either cap, transactions pay their own gas until the window resets. Bankr doesn't sponsor raw transactions or arbitrary contract calls.

Robinhood Chain
Robinhood's Arbitrum Orbit L2, home to tokenized stocks, ETFs, and memecoins.
Capabilities:
- Tokenized stocks and ETFs — 190+ Robinhood-issued equities (NVDA, AAPL, SPY, and more). Requires location verification; not available in the US, UK, or sanctioned regions
- Memecoin swaps (no verification required), routed through the 0x and Relay aggregators or directly against a fresh Bankr launch's Uniswap v4 pool
- Limit orders, stop orders, DCA and TWAP on memecoins and tokenized stocks. Stock limit and stop orders need an on-chain pool for that stock to watch, and a stock order that triggers outside US market hours can't fill until the market reopens
- Token launching with fee sharing
- USDG (Global Dollar) as the chain's native stablecoin
- Cross-chain bridging via Relay
- Gas sponsorship for transactions other than retail token launches (the launch wallet pays network gas)

Arc
Circle's L1 where USDC is the native gas token (one balance, exposed both as the 18-decimal native view and the 6-decimal ERC-20 at 0x3600000000000000000000000000000000000000). No wrapped native token exists.
Capabilities:
- Balances and USDC/ERC-20 transfers
- Raw transactions, contract deploys
- Token launches on Bankr Launch v3, quoted in native USDC (the chain's only launch quote)
Note: No aggregator swaps yet (0x/Relay do not route Arc). Gas is paid in native USDC and is not sponsored.
Block Explorer: Arcscan (third-party until Circle publishes the official explorer)
Solana
High-speed SVM chain for fast trading.
Capabilities:
- Token swaps via Jupiter aggregator
- Cross-chain swaps
- Limit and stop orders as Jupiter trigger orders (0.5% fee when they fill); no DCA or TWAP

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 POL 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 and Solana using bridge aggregators:
"swap $50 USDC from polygon to ETH on base"
"swap $20 USDC from base to SOL on solana"
