SubWallet

SubWallet is a non-custodial wallet for Polkadot, Kusama and the EVM ecosystem with extension, mobile and web clients, serving parachain users, stakers and governance participants. A multi-chain account model pushes users to re-import seed phrases across relay chains and parachains while asset views and signing requests stay fragmented, and differing signature formats and fee assets force constant switching of networks and balance sources.

One master password manages several seed phrases with accounts synced across devices; cross-consensus transfers bundle relay and destination calls into a single confirmation with one signature, swaps query multiple pools and route along the best path, and staking covers direct nomination, nomination pools, collators and liquid staking. Assets group by chain with a unified conversion, connections list requested permissions by site identifier and calls decode into method and arguments. The code is open source and independently audited, with support for Ledger, Keystone and air-gapped signers.
