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.

Capabilities:
- Token swaps, routed through the 0x and Relay aggregators across Base DEXs (Uniswap, Aerodrome and more)

Ethereum
Ethereum mainnet for high-value operations.
Capabilities:
- Token swaps, routed through the 0x and Relay aggregators
- Limit orders, stop orders, DCA, TWAP
- NFT buying, selling, and minting
Note: Gas is not sponsored on Ethereum mainnet due to high costs.

Polygon
Low-cost EVM chain with Polymarket support.
Capabilities:
- Token swaps, routed through the 0x and Relay aggregators
- Limit orders, stop orders, DCA, TWAP
- Polymarket betting

Block Explorer: Uniscan
World Chain
World Chain (Worldcoin's L2) with gas sponsorship.
Capabilities:
- Token swaps, routed through the 0x and Relay aggregators
- Cross-chain swaps
- Limit orders, stop orders, DCA, TWAP
- Gas sponsorship for transactions
Block Explorer: Worldscan
Arbitrum
Leading Ethereum L2 with deep DeFi liquidity.
Capabilities:
- Token swaps, routed through the 0x and Relay aggregators
- Cross-chain swaps
- Limit orders, stop orders, DCA, TWAP
- Token launching with fee sharing (WETH-paired; the launch wallet pays network gas)
- Gas sponsorship for transactions other than retail token launches

BNB Chain
BNB Chain (formerly Binance Smart Chain) with deep DeFi liquidity.
Capabilities:
- Token swaps, routed through the 0x and Relay aggregators
- Cross-chain swaps
- Limit orders, stop orders, DCA, TWAP
- Gas sponsorship for transactions
Block Explorer: BscScan
Hyperliquid
High-performance on-chain order book for perpetual futures and spot trading.
Capabilities:
- Perpetual futures (crypto, stocks, commodities)
- Spot trading (HYPE, PURR, and more)
- Position management (leverage, margin, TP/SL)
- Order management (limit, modify, cancel)
- Bridge deposits from Arbitrum, Base, Polygon, Ethereum
- Bridge withdrawals to Arbitrum
Note: Hyperliquid is its own L1. Funds are bridged via Arbitrum. Deposits auto-detect the best source chain.

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.

Elysium
Kinetiq's Arbitrum Orbit L2 on HyperEVM (chain ID 99901), where HYPE is the native gas token. Not to be confused with VulcanForged's Elysium (chain 1338).
Capabilities:
- Wallet: balances, and sending and receiving HYPE and tokens, at the same EVM address as on other chains. Name Elysium when you send HYPE there: HYPE with no chain named means Hyperliquid's. Smart wallets, such as Coinbase Smart Wallet or a Safe from another chain, aren't supported: they have no code on Elysium, so HYPE sent to one there can't be moved.
- HYPE ↔ WHYPE wraps
- Raw transactions and contract calls
- Swaps: on Elysium's own Uniswap pools, each with HYPE or WHYPE on one side. No cross-chain swaps into or out of Elysium.
- Bridging: HYPE between HyperEVM and Elysium, both ways, from your Trading wallet, in chat or on the Wallet page. A withdrawal reaches HyperEVM after Elysium's challenge period, about 6 days, and Bankr claims it for you. To bridge another wallet of yours into Elysium, connect it on Kinetiq's bridge.
- Limit and stop orders from your Trading wallet, in chat or on the Trade page: a token against WHYPE (wrap HYPE first), triggered in dollars or in WHYPE. Each fills no worse than its trigger less its slippage, and a stop also less its pool's fee. Buying a token no scanner covers asks you to accept its risk first. Trailing stops, DCA and TWAP aren't available on Elysium yet.
- Token launches: not yet
Note: Gas is paid in HYPE and is not sponsored, so a wallet needs HYPE on Elysium to move anything there. Kinetiq hasn't published a canonical USDC on Elysium yet, so Bankr names no stablecoin there.

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
Note: Gas sponsorship is limited on Solana.

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"
