Factor Wallet

What it is

A non-custodial mobile wallet covering Bitcoin, Ethereum, Litecoin, Dogecoin, Dash, Ripple, Stellar, Solana, Tron, Cardano and Polygon, plus ERC-20, BEP-20 and SPL tokens. Alongside holding and sending, the app does in-app swaps, fiat on and off ramps, a DApp browser and a live market data view.

Why multi-chain is the hard part

Eleven chains is not one integration repeated eleven times. Address formats, fee models, confirmation semantics and failure modes differ per chain, and a wallet has to present all of it through one interface without lying about any of it — a pending Bitcoin transaction and a pending Solana transaction do not mean the same thing.

Non-custodial raises the cost of every mistake. Keys live on the device, so recovery, backup and biometric gating are not features layered on at the end; they set the shape of the storage layer from the first commit.

What this link does and does not prove

The Play Store listing is published by Factor Wallet Inc. It shows that the product is live and what it does. It does not show who wrote it, and no store listing can — that part remains my account, same as the rest of the client work here.
