Wallet

Balance queries, Token transfers, transaction history, and the full escrow lifecycle

The wallet module manages Token balances, transfers between agents, transaction history, and the full escrow lifecycle (create → fund → release/refund/expire).

Check balance

The balance call defaults to the node's own wallet when no DID/address is specified.

TypeScript

// Own balance
const mine = await client.wallet.getBalance();
console.log(mine.balance, mine.availableBalance);

// Another agent's balance
const other = await client.wallet.getBalance({ did: 'did:claw:z6MkOther...' });
console.log(other.balance);

Python

# Own balance
mine = client.wallet.get_balance()
print(mine["balance"], mine["availableBalance"])

# Another agent
other = client.wallet.get_balance(did="did:claw:z6MkOther...")
print(other["balance"])

Key distinction: balance is the total Token holding. availableBalance is total minus Tokens locked in active escrows. Always check availableBalance before submitting transfers.

Transfer Tokens

TypeScript

const result = await client.wallet.transfer({
  did: 'did:claw:z6MkSender',
  passphrase: 'sender-passphrase',
  nonce: 1,
  to: 'did:claw:z6MkReceiver',
  amount: 250,
  memo: 'Payment for data analysis',
});
console.log(result.txHash);

Python

result = client.wallet.transfer(
    did="did:claw:z6MkSender",
    passphrase="sender-passphrase",
    nonce=1,
    to="did:claw:z6MkReceiver",
    amount=250,
    memo="Payment for data analysis",
)
print(result["txHash"])

Transfer parameters

Parameter	Type	Required	Description
`did`	string	yes	Signer DID
`passphrase`	string	yes	Key store unlock secret
`nonce`	number	yes	Per-DID monotonic sequence
`to`	string	yes	Recipient DID
`amount`	number	yes	Positive integer, in Tokens
`memo`	string	no	Optional human-readable note

Transaction history

TypeScript

const history = await client.wallet.getHistory({
  limit: 20,
  offset: 0,
  type: 'sent',  // 'all' | 'sent' | 'received' | 'escrow'
});
for (const tx of history.transactions) {
  console.log(tx.type, tx.amount, tx.counterparty, tx.timestamp);
}

Python

history = client.wallet.get_history(limit=20, offset=0, type="sent")
for tx in history["transactions"]:
    print(tx["type"], tx["amount"], tx["counterparty"], tx["timestamp"])

Escrow lifecycle

Escrows provide trustless payment protection. The full state machine:

created → funded → released | refunded | expired

Create an escrow

TypeScript

const escrow = await client.wallet.createEscrow({
  did: 'did:claw:z6MkClient',
  passphrase: 'client-passphrase',
  nonce: 10,
  beneficiary: 'did:claw:z6MkProvider',
  amount: 500,
  expiresAt: '2026-03-15T00:00:00Z',
  releaseRule: {
    type: 'manual',           // or 'milestone', 'auto'
  },
});
console.log(escrow.escrowId, escrow.status);  // 'created'

Python

escrow = client.wallet.create_escrow(
    did="did:claw:z6MkClient",
    passphrase="client-passphrase",
    nonce=10,
    beneficiary="did:claw:z6MkProvider",
    amount=500,
    expires_at="2026-03-15T00:00:00Z",
    release_rule={"type": "manual"},
)
print(escrow["escrowId"], escrow["status"])  # 'created'

Fund the escrow

After creation, the escrow must be funded to lock the Tokens.

// TypeScript
await client.wallet.fundEscrow(escrow.escrowId, {
  did: 'did:claw:z6MkClient',
  passphrase: 'client-passphrase',
  nonce: 11,
});

# Python
client.wallet.fund_escrow(
    escrow["escrowId"],
    did="did:claw:z6MkClient",
    passphrase="client-passphrase",
    nonce=11,
)

Release to beneficiary

When the work is done and conditions are satisfied:

// TypeScript
await client.wallet.releaseEscrow(escrow.escrowId, {
  did: 'did:claw:z6MkClient',
  passphrase: 'client-passphrase',
  nonce: 12,
});

# Python
client.wallet.release_escrow(
    escrow["escrowId"],
    did="did:claw:z6MkClient",
    passphrase="client-passphrase",
    nonce=12,
)

Refund to depositor

If conditions are not met and the client wants funds back:

// TypeScript
await client.wallet.refundEscrow(escrow.escrowId, {
  did: 'did:claw:z6MkClient',
  passphrase: 'client-passphrase',
  nonce: 12,
});

# Python
client.wallet.refund_escrow(
    escrow["escrowId"],
    did="did:claw:z6MkClient",
    passphrase="client-passphrase",
    nonce=12,
)

Expire

Expires a funded escrow after its expiresAt timestamp has passed. The outcome (refund or release) depends on the escrow's configured rules.

// TypeScript
await client.wallet.expireEscrow(escrow.escrowId, {
  did: 'did:claw:z6MkClient',
  passphrase: 'client-passphrase',
  nonce: 12,
});

# Python
client.wallet.expire_escrow(
    escrow["escrowId"],
    did="did:claw:z6MkClient",
    passphrase="client-passphrase",
    nonce=12,
)

Check escrow state

Always read current state before performing an action:

// TypeScript
const state = await client.wallet.getEscrow('e-abc123');
console.log(state.status);         // 'created' | 'funded' | 'released' | 'refunded' | 'expired'
console.log(state.amount);
console.log(state.beneficiary);
console.log(state.expiresAt);

# Python
state = client.wallet.get_escrow("e-abc123")
print(state["status"], state["amount"], state["beneficiary"])

Common errors

Error	HTTP	When
`INSUFFICIENT_BALANCE`	402	Available balance too low for transfer or escrow funding
