Agent Wallet — A wallet your agent can actually use

Why agent wallet

Designed for the way agents actually work.

Traditional wallets assume a human is watching. Agent Wallet assumes nobody is — and gives your agent everything it needs to operate safely on its own.

01 / NON-INTERACTIVE

Zero prompts, zero clicks.

Every command takes --yes. No modals, no browser extensions, no GUI in the loop. Pipe stdout straight into jq and keep moving.

$ begin send addr1q…rty 10 --yes --json ✓ submitted · txHash a3f1c89e… exit 0

02 / JSON-NATIVE

Output your agent can parse.

Append --json to anything. Structured success and error envelopes, stable shapes, exit codes worth listening to.

{ "success": true, "data": { "txHash": "a3f1…", "fee": "0.170000" } }

03 / MULTI-CHAIN

One wallet.
Four chains.

Cardano, Solana, Bitcoin, and EVM addresses derived from a single wallet. Send, receive, balance — same flags everywhere.

04 / KEYS STAY HOME

Encrypted on-device.

Wallets are generated and stored locally with AES-256-GCM, optionally backed by the OS keychain. No remote signers, no cloud sync. Backup is a one-line export when you want it.

05 / OFFLINE SIGNING

Air-gapped by design.

Build on an online machine, sign on an offline one, submit anywhere. Drop in hardware wallets via the same flow.

06 / EXIT CODES THAT MEAN SOMETHING

Errors agents can recover from.

Insufficient funds is 4. Network unreachable is 3. Wrong password is 11. Build retry logic that's actually retry logic.

07 / SKILLS & MCP

Drop-in for your agent stack.

Ships with Skill manifests for OpenClaw and an MCP server for Claude / Cursor / any host. Wire it in once, expose six commands.

The command line is the API.

If your agent can call a shell, it can hold a wallet. Wire it into your stack via shell, Python, MCP, or skill manifest — same surface, same JSON shape.

# Check balance, then conditionally send
$ BALANCE=$(begin balance --json | jq '.data.balance.ada')

$ if (( $(echo "$BALANCE > 10" | bc) )); then
    TX=$(begin send addr1recipient 5 --yes --json)
    echo "Sent! TX: $(echo $TX | jq -r '.data.txHash')"
fi

Skills · MCP · Hooks

Six skill manifests, ready to ship.

Every capability area ships as a Skill manifest your agent can load directly. No glue code, no schema-writing — just point your runtime at the skills directory.

skill / begin-wallet

Wallet ops

Create, restore, list wallets · derive addresses across all four chains · export with care.

$ begin wallet address --json

skill / begin-discovery

Discovery

Search tokens, fetch prices, inspect on-chain history. Read-only primitives for planning.

$ begin token search HOSKY

skill / begin-staking

Staking

Browse pools, delegate, check status, withdraw rewards. Yield strategies as one-liners.

$ begin stake delegate BEGIN

skill / begin-swap

Swap

Quote, execute, cancel DEX orders. Slippage and routing exposed in JSON for agent decision-making.

$ begin swap 10 ADA SNEK

skill / begin-mint

Mint

Define policies, mint native tokens, manage on-chain provenance — all programmable.

$ begin mint --policy ./p.json

skill / begin-offline

Offline signing

Build → transfer → sign → submit. Air-gap-friendly workflow with file or QR-code handoff.

$ begin sign --tx unsigned.tx

Security

Trust the cryptography, not the chrome.

No browser extensions to phish. No remote signing services. Keys are derived, encrypted, and used locally — or kept in memory only, if that's your threat model.

01
AES-256-GCM at rest
Wallets stored in ~/.begin-cli/wallets/ are encrypted with a password you choose.
02
OS keychain integration
macOS Keychain, Windows Credential Manager, Linux Secret Service — opt-in, no password retyping.
03
You own the recovery
Backup phrase is exported only when you ask. Until then it lives encrypted on disk — never on a server, never in a browser extension.
04
Air-gapped signing
Build transactions online, sign on a separate machine, submit anywhere. Files or QR codes — your call.

FAQ

Common questions.

How is this different from Begin Wallet?

Begin Wallet is the consumer-facing wallet for humans — browser extension, mobile app, friendly UI. Agent Wallet is the same crypto primitives reshaped for autonomous agents: headless, scriptable, JSON-out. Same team, same security model, different surface.

Do I need to hold crypto to check balances?

No. Read-only operations — balances, history, UTXOs, token metadata — are free across every supported chain. You only need funds when you're sending, staking, or swapping.

Where are my keys stored?

Locally, encrypted with AES-256-GCM, in ~/.begin-cli/wallets/. Optionally backed by the OS keychain (macOS, Windows, Linux). All cryptographic operations — derivation, signing, encryption — happen on-device. Network calls are read-only against Blockfrost and chain RPCs.

Can I use this on testnet?

Yes. Pass --network preprod or --network preview. Get test ADA from the Cardano Faucet, test SOL from devnet faucets, etc. We recommend starting there.

Is this safe for production agents?

It's beta. Use small amounts, set spending limits at the agent layer, prefer offline-signing for high-value flows, and monitor your addresses. Same advice as any wallet, more applicable when nobody's watching.

What chains are supported?

Today: Cardano, Solana, Bitcoin, and EVM (Ethereum + L2s). All four addresses are derived from a single wallet. More chains are on the roadmap.

Why a CLI and not an SDK?

Agents already know how to call shells. The CLI surface is a forcing function for clean, composable, JSON-shaped operations. We expose the underlying TypeScript as a library too if you need it.
