[1.11.1] - 2025-06-04

Bugfixes

  • Fixed taker parameter logic to align Python SDK with TypeScript SDK behavior:

    • Removed taker parameter from SwapOptions - Account swap methods now always use the account address as taker, preventing confusion about which address receives the swapped tokens
    • Updated account.swap() - Always uses self.address as taker instead of allowing custom taker via SwapOptions
    • Updated account.quote_swap() - Always uses self.address as taker (previously could be overridden)
    • Maintained explicit taker requirement - Global methods (cdp.evm.get_swap_price(), cdp.evm.create_swap_quote()) still require explicit taker parameter for flexibility
    • Updated examples and documentation - All examples now reflect the simplified taker logic

    This change provides a cleaner API where account-level convenience methods always swap to the account address, while global methods require explicit specification for external wallet integrations.

    (#182)

    • Support for swapping tokens using contract addresses
    • Configurable slippage protection (slippage_bps) with automatic optimal routing
    • Returns SwapUnavailableResult when liquidity is insufficient
    • Consistent parameter naming: from_token, to_token, from_amount
