B28 is a non-custodial wallet. It holds, sends, and receives across 16 networks and around 48 assets, all from keys that live on your own device. We never hold your funds. Here is exactly what is supported, and all of it comes from the one recovery phrase you write down when you set the wallet up.
Bitcoin and UTXO chains
The original family of networks, secured by their own proof-of-work and large fee markets.
- Bitcoin
- Litecoin
- Dogecoin
Ethereum and its Layer 2s
Ethereum plus the major rollups and sidechains that settle to it. On these chains you can hold the native coin and the major stablecoins USDC and USDT.
- Ethereum
- Polygon
- Arbitrum
- Optimism
- Base
- BNB Chain
- Avalanche
Other Layer 1s
Independent base chains, each with its own design and signing scheme. USDC and USDT are also supported on Solana.
- Tron
- Solana
- XRP
- TON
- Stellar
- Cardano
How we add assets
We do not auto-list tokens from a public registry. Before any chain or token ships, its address and decimals are first-party verified against the issuer's own published source. That is slower, and it is the point: a wallet that lists the wrong contract for a stablecoin can quietly send your money to a look-alike token. Every one of the roughly 48 assets here passed that check before it reached you.
Safety on every chain
Wherever you transact, the Sentinel scam-shield screens the recipient and the token before you sign: it flags drainer approvals, address poisoning, and honeypot tokens, and warns you first. Sending is free from B28; you pay only the network's own fee, which goes to the blockchain and not to us. See the full breakdown on Fees.
