Wardenby Drinker Labs

A smart-account wallet for Solana

Your wallet.
Your boundaries.

A passkey for authority. Clear limits for what comes next. Warden is building a wallet where the rules for spending live with the account, on-chain.

01 / The idea

Give every key
a defined job.

A wallet can separate ownership from everyday activity. Warden’s program gives each layer its own responsibilities.

01

Keep authority
with your passkey.

A device passkey authorizes root actions. The on-chain program verifies the signature and binds it to the requested action.

Available in the devnet test flow

02

Put boundaries
around sessions.

The program supports expiring session keys with scoped permissions, per-transaction caps and lifetime limits.

Program implemented · test UI integration ahead

03

Make the account
enforce the rules.

Shared daily and 30-day spending limits apply across sessions and direct root actions. A passkey approval still has to respect them.

Implemented in the on-chain program

02 / Make the limits tangible

A boundary you
can see.

One transfer has to fit every spending limit. Explore four examples using the current devnet test policy.

Daily and 30-day usage accumulate across the account. Splitting an amount across several transfers does not create a fresh account-wide budget.

This is an illustration, with example spending history. It does not connect to a wallet or send funds. Actual transfers also require authentication, sufficient funds and other program checks.

Fits these spending limits

The transfer and both accumulated totals stay within their caps.

This transfer0.001 / 0.01 SOL
Daily total after0.021 / 0.1 SOL
30-day total after0.201 / 1 SOL

Example already spent: 0.02 SOL today · 0.2 SOL in 30 days.

03 / From the actual build

A real account.
A first transfer.

These are captures from the experimental desktop Chrome test flow on 6 September 2026. The finished consumer wallet is still being built.

0.001 test SOL, confirmed on devnet. The recorded run used real network transactions and a simulated browser authenticator. Physical-device passkeys remain unverified.

04 / Where Warden stands

The ambition is clear.
So is the work ahead.

Program features, a test interface and a finished wallet are different milestones. Here is the current split.

Available to test

A devnet first step.

  • Manual install in desktop Chrome
  • Passkey enrollment and account creation
  • Explicit connection to the test website
  • Passkey-approved native SOL transfers
  • Balance reads and transaction receipts

Separate experimental build. Test SOL only.

Implemented foundation

Rules behind the wallet.

  • Passkey root verification
  • Scoped, expiring session keys
  • Shared spending limits and freeze controls
  • Constrained execution and conservation checks
  • A Jupiter v6 swap adapter

Program capabilities do not mean every feature is available in the test interface.

Still ahead

The complete everyday wallet.

  • An integrated create, reopen and unlock journey
  • Wallet discovery and everyday app connections
  • Timelocked larger moves and policy updates
  • Guardian recovery
  • External audit and mainnet readiness

No launch date or mainnet release is announced.

05 / Take a closer look

Meet your
Warden.

The experimental devnet build is available for desktop Chrome. The setup page has the download and step-by-step installation instructions.

Chrome 120+ on desktop · Manual installation
Unaudited · Use test SOL only

Can I use it with real funds?

Warden is pre-alpha and has not been externally audited. The downloadable test build is limited to Solana devnet. Use test SOL only; mainnet use is not available.

Is it in the Chrome Web Store or on mobile?

The devnet build installs manually as an unpacked desktop Chrome extension. It is not a Web Store release, and there is no native mobile app available.

Can I swap or connect to any app?

The current test build supports its dedicated test website and native SOL transfers. General wallet discovery, everyday app integration and a consumer swap interface are still ahead.

What is next?

A complete journey in the regular extension: create an account, reopen the browser, unlock the same wallet, receive and send, then connect to apps through wallet discovery. Timelocks, guardian recovery and release assurance remain separate work.
