What you get

A wallet that's actually yours

No accounts, no custody, no servers holding your funds. Just a fast, private wallet you control.

Encrypted on-device

Your recovery phrase is generated locally and sealed with your password using the browser's own cryptography. It never leaves your machine.

Multi-chain

Base, Ethereum, Optimism, Arbitrum and Polygon out of the box. One address, every EVM chain.

Connect to any dApp

Bismuth announces itself via EIP-6963, so it appears right alongside MetaMask and Rabby. Connect and sign in a click.

Send, receive & track

Move coins and tokens with a live fee estimate, share a QR to receive, and watch transactions confirm in real time.

You hold the keys

Reveal your phrase or export a private key anytime — behind your password. Fully portable, always yours.

Iridescent by design

Named for element 83's rainbow crystal. A wallet that looks as good as it works.

Four steps

Up and running in a minute

No sign-up, no KYC. Create a wallet and you're live.

1

Create

Spin up a new wallet or import your recovery phrase.

2

Back up

Write down your phrase. It's the only key, and it's yours.

3

Connect

Open any dApp and pick Bismuth from the wallet list.

4

Sign

Approvals open in their own window. You stay in control.

Non-custodial by construction

Bismuth can't freeze, seize, or lose your funds — because it never holds your keys. Your phrase lives on your device, encrypted, and nowhere else.

Questions

Good to know

Is Bismuth custodial?+
No. It's fully self-custodial. Your recovery phrase and keys are generated and encrypted on your own device. Bismuth has no server that can access your funds.
Which networks are supported?+
Base, Ethereum, Optimism, Arbitrum and Polygon at launch — with one address across every EVM chain.
Do you see my balance or transactions?+
No tracking and no accounts. Balances are read directly from public RPCs; nothing about you is sent to us.
What if I lose my password?+
There's no password reset — that's the point of self-custody. You can always restore your wallet on any device with your recovery phrase.
