Polkaswap provides SORA-based token swaps, liquidity pools and an order-book interface. Its published 0.30% swap charge is only one cost layer: network costs and order-placement charges have separate descriptions. The legal page names Polka Biome Ltd. but is dated 12 April 2021, while the wiki also describes community governance and more recent trading workflows.[1][2][5]

- Pricing scope
- Wiki and dated terms publish a 0.30% swap fee. Network fees are separate; order-book placement has a quote-dependent charge and its guide describes free cancellation. Current transaction details should be used rather than treating 0.30% as a universal all-in rate.
- Funding scope
- SORA wallet assets fund trading, with XOR used for network costs. The FAQ describes a limited swap-to-XOR fee-deduction route; external-chain transactions require their own gas and bridge conditions.
- Custody and asset handling
- User-controlled wallets authorise network operations. Pool deposits and token/bridge arrangements create separate asset exposures. The terms state private keys are not held by the service.
- Client eligibility
- Published April 2021 terms require age 18, lawful use and sanctions compliance, and exclude named locations including the United States, Japan and Singapore. Wallet connectivity does not establish permission to use the interface.
- Support
- Official wiki guidance and the Polkaswap community channel linked in the terms; transaction history and explorer records identify technical issues.
- Authorisation and registration scope
- The dated terms describe a community software interface and name Polka Biome Ltd.; no specific financial-services permission is established. BVI governing law is not evidence of incorporation or licensing.
