Wallet

Interact with this agent's on-chain wallets. Each agent has one wallet per chain (EVM + Solana). Supports balance queries, transfers (policy-gated), message signing, and transaction history.

Authentication is automatic via Fly OIDC token — no API keys or wallet addresses needed. Wallets are bound to this machine at deploy time.

Tool Usage Examples

Check Wallet Info (All Chains)

wallet_info()

Returns: list of

wallets

with

wallet_address

and

chain_type

for each active wallet.

Use this first to see all available wallets before any operations.

EVM — Check Balance

IMPORTANT: Always specify the
chain
parameter! To check all chains at once, use
wallet_get_all_balances
instead.

wallet_balance(chain="ethereum")  # Get ALL tokens on Ethereum
wallet_balance(chain="base", asset="usdc")  # Check specific asset on Base
wallet_balance(chain="polygon", asset="pol")  # Polygon requires explicit asset

chain parameter is REQUIRED. Valid chains:

ethereum

base

arbitrum

optimism

polygon

linea

Asset naming:

For Polygon native token, use
```
"pol"
```
NOT
```
"matic"
```
Use lowercase symbolic names like
```
"usdc"
```
,
```
"weth"
```
,
```
"usdt"
```
DO NOT pass contract addresses (e.g.,
```
"0x..."
```
), use symbols only
Omit
```
asset
```
parameter to discover ALL tokens on the specified chain

Known Limitation - Polygon: The Polygon chain requires explicit asset parameters. Instead of:

wallet_balance(chain="polygon")  # ❌ May fail with "eth not supported"

Use:

wallet_balance(chain="polygon", asset="pol")  # ✅ Check POL balance
wallet_balance(chain="polygon", asset="usdc")  # ✅ Check USDC balance

For complete Polygon portfolio, use

wallet_get_all_balances()

which handles this correctly.

For checking balances across ALL chains in one call, use

wallet_get_all_balances()

instead.

Multi-Chain — Get All Balances

wallet_get_all_balances()

This is the PRIMARY tool for comprehensive balance checks.

Automatically checks ALL supported chains (Ethereum, Base, Arbitrum, Optimism, Polygon, Linea, Solana) and returns complete portfolio with USD values.

Use this instead of calling

wallet_balance()

multiple times for different chains.

EVM — Query Transaction History

wallet_transactions()
wallet_transactions(chain="ethereum", asset="eth", limit=10)
wallet_transactions(limit=50)

Defaults:

chain="ethereum"

asset="eth"

limit=20

(max 100).

Returns: list of transactions with

tx_hash

from

to

amount

status

timestamp

```
amount
```
: Amount in wei (not ETH).
```
"1000000000000000000"
```
= 1 ETH. Use
```
"0"
```
for contract calls that don't send ETH.
```
chain_id
```
: Chain ID (default: 1 = Ethereum mainnet, 8453 = Base, 10 = Optimism)
```

```
nonce
```
: Transaction nonce (decimal string). Optional — auto-determined if omitted.
```

```
1
```
=EIP-2930,
```
2
```
=EIP-1559,
```
4
```
=EIP-7702. Optional.

Policy enforcement: Transfers are gated by Privy TEE policy. The target address must be on the whitelist and the amount must be within daily limits. Policy violations return an error.

EVM — Sign Transaction (without broadcasting)

wallet_sign_transaction(to="0xRecipientAddress", amount="1000000000000000000")
wallet_sign_transaction(to="0xRecipientAddress", amount="1000000000000000000", chain_id=8453)
wallet_sign_transaction(to="0xContractAddress", amount="0", data="0xa9059cbb000000...", chain_id=8453, tx_type=2, max_fee_per_gas="30000000000", max_priority_fee_per_gas="2000000000")

Same parameters as

wallet_transfer

, plus

max_fee_per_gas

and

max_priority_fee_per_gas

for EIP-1559.

Wei Conversion Reference (EVM)

Amounts are always in wei (smallest unit). Conversion table:

Amount	Wei String
0.001 ETH	`"1000000000000000"`
0.01 ETH	`"10000000000000000"`
0.1 ETH	`"100000000000000000"`
1 ETH	`"1000000000000000000"`
10 ETH	`"10000000000000000000"`

Formula:

wei = eth_amount * 10^18

Chain ID Reference (EVM)

Chain	ID	CAIP-2	Native Asset
Ethereum Mainnet	1	`eip155:1`	`eth`
Ethereum Sepolia	11155111	`eip155:11155111`	`eth`
Base	8453	`eip155:8453`	`eth`
Optimism	10	`eip155:10`	`eth`
Arbitrum One	42161	`eip155:42161`	`eth`
Polygon	137	`eip155:137`	`pol` (NOT "matic")
Linea	59144	`eip155:59144`	`eth`

Solana CAIP-2 Reference

Network	CAIP-2
Solana Mainnet	`solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp`
Solana Devnet	`solana:EtWTRABZaYq6iMfeYKouRu166VU2xqa1`

Policy & Security

Privy TEE enforced: Even if the agent is compromised, transfers that violate policy are rejected at the Privy TEE layer
Per-wallet policy: Each chain's wallet has its own independent policy
Flexible rules: Policy rules are configured via Privy's rule system (address allowlists, value limits, method restrictions, etc.)
Deny-all default: New wallets have no allowed transfers until policy is configured by the user via the backend
Pass-through: Policy rules are managed directly via Privy (source of truth), no local cache

Policy is managed by the user through the main backend API, not by the agent.

Error Handling

Error	Meaning	Action
"Not running on a Fly Machine"	Wallet requires Fly deployment	Cannot use wallet locally
"Policy violation: ..."	Transfer rejected by Privy policy	Check whitelist and daily limits
"HTTP 404"	Wallet not found for this machine	Wallet may not be created yet
"HTTP 403"	OIDC token invalid or expired	Token will auto-refresh, retry
