# AI Agent Wallets: Balances, Spending and Who Agents Pay > AI agent wallets on-chain: wallets linked to agents by registries, their balances, who they pay and what they spend on gas, x402 payments, swaps and jobs. Markdown copy of https://voltfincrypto.com/apps/ai-agent-wallets-spending **Question:** How many wallets do AI agents control, what do they hold and what do they spend their money on? - Kind: Dashboard in Voltfin Vantage - Topic: [AI and agents](https://voltfincrypto.com/topics/ai-agents) - Chains: Base, Ethereum, Solana, Gnosis, OP Mainnet - Status: Planned. The data is not published yet, so this page states no figure; each figure will open its receipt when it is. An AI agent that pays for things needs a wallet it can use without a person signing each transaction. Some agent wallets are smart accounts with spending limits, some are multisigs controlled by agent keys and some are accounts bound to an agent's NFT. Wallet products built for agents are now common, including the agentic wallets Coinbase launched in February 2026. This dashboard counts only wallets that on-chain evidence links to an agent, such as a registration in an ERC-8004 identity registry, the multisig of a registered Olas service or the account bound to a Virtuals agent, and records which evidence applies. It then shows what those wallets hold and where their money goes: gas, paid API calls such as x402 payments, swaps, jobs paid to other agents and plain transfers. ## Blueprint ### Wallets Agent wallets, what they hold and how active they are. - **Agent wallets** (count): Wallets linked to an agent by on-chain evidence that were active in the last 30 days. - **Active today** (count): Listed agent wallets that sent a transaction or payment on the latest complete day. - **Held by agent wallets** (USD): Holdings of listed agent wallets in stablecoins and priced tokens at the latest day's last block. - **Spent today** (USD): Outflows from listed agent wallets on the latest complete day, transfers between an agent's own wallets removed. - **Active wallets by evidence** (count): Active agent wallets per day by the evidence that lists them: ERC-8004, Olas, Virtuals or a wallet factory. ### Spending Where agent money goes and who receives it. - **Spent on gas** (%): Share of agent wallet spending in the period that went to gas. - **Paid to other agents** (%): Share of agent wallet payments in the period whose recipient is another listed agent wallet. - **Spending by category** (USD): Spending per week by category: gas, paid API calls, swaps, agent jobs and transfers. - **Who agents pay**: Addresses receiving the most from agent wallets in the period, labelled as x402 services, DEX routers, other agents or unknown. Filters: Period (Last 7 days, 30 days or 12 months); Chain (Base, Ethereum, Solana, Gnosis, OP Mainnet or all). ## How it will be measured - A wallet enters the list only with on-chain evidence: an agent wallet named in an ERC-8004 registration, a deployed Olas service multisig, a Virtuals agent's token-bound account or an account deployed by a published agent wallet factory. - Balances are each wallet's stablecoin, native and registry token holdings at the day's last block, valued with oracle prices where a feed exists. - Spending is outflows from listed wallets, sorted by what they paid for: gas, x402 and other paid API settlements, DEX swaps, agent job escrows and transfers, with transfers between wallets of the same agent removed. - A payment counts as agent to agent when the receiving address is also on the list, so the share of agents paying other agents can be measured. ## Data it needs - `agent_payments_daily` (to build): Agent tokens (supply, holders, trading) and agent payments such as x402 settlements in stablecoins, per day. - `address_labels` (to build): Labels for known addresses: exchanges, bridges, protocols, funds, treasuries, sanctioned addresses and known attackers. - `token_transfers_daily` (to build): ERC-20 and native transfer counts, volume and unique senders and receivers per token per chain per day. - `account_abstraction_daily` (to build): ERC-4337 UserOperations, bundlers and paymasters, and EIP-7702 delegations per chain per day. - `stablecoin_flows_daily` (to build): Stablecoin mints, burns, transfer volume and active addresses per stablecoin and chain per day. - `native_prices_daily` (to build): Reference prices of major assets read from on-chain oracle feeds (Chainlink latestRoundData) at each day's last block, with each round's update time. - Source: ERC-8004 identity registry records that name an agent's wallet - Source: Olas service multisig deployments and Virtuals agents' token-bound accounts - Source: Account deployments from agent wallet factory contracts, where a factory is published for agents - Source: Token transfers, native transfers and gas receipts of every listed wallet - Source: x402 settlement transfers and agent job escrow events - Source: Chainlink price feeds, for USD values ## Questions ### What is an AI agent wallet? A wallet an autonomous program uses to hold funds and pay without a person approving each transaction. It can be a smart account with spending limits, a multisig controlled by agent keys or an account bound to an agent's NFT. ### How are agent wallets identified? Only through on-chain evidence, such as an ERC-8004 registration that names the wallet, an Olas service's multisig or a Virtuals agent's bound account. Wallets that merely behave like bots are not counted, so the list undercounts rather than guesses. ### What do AI agents spend money on? The spending view sorts outflows into gas, paid API calls such as x402 payments, swaps, jobs paid to other agents and plain transfers, so the mix can be compared across chains and over time. ### Do agent wallets have spending limits? Many do. Smart accounts built for agents can cap amounts per payment or per day and restrict tokens and recipients, enforced by the account's own contract. Where a wallet's limits can be read on-chain, they are recorded with the wallet. ### Is this the same as x402 volume? No. x402 payments come from many payers, including apps and people. This dashboard starts from the agents' wallets and shows x402 as one of several things they spend on, beside gas, swaps and jobs. ## Glossary - **Token-bound account**: A smart contract account owned by an NFT under ERC-6551, so whoever holds the NFT controls the account's assets. - **Session key**: A limited key a wallet grants for a time or a purpose, letting an agent sign some transactions without the main key. - **Agent-to-agent payment**: A payment from one listed agent wallet to another, such as a fee for a job or a tool call. ## Related apps - [x402 Transactions Tracker: Daily Payments and Volume](https://voltfincrypto.com/apps/x402-transactions-tracker) - [ERC-8004 Agent Registry: Registered AI Agents by Chain](https://voltfincrypto.com/apps/erc-8004-agent-registry) - [Olas Autonomous Agents: Services, Staking and Mech Requests](https://voltfincrypto.com/apps/olas-agent-services-staking) - [Virtuals Protocol Agents: Launches, Jobs and Payments](https://voltfincrypto.com/apps/virtuals-protocol-agents) - [AI Agents in Crypto: Monthly On-Chain Report](https://voltfincrypto.com/apps/ai-agents-in-crypto-monthly-report) - [AI Agent Tokens Ranked by Holders and DEX Volume](https://voltfincrypto.com/apps/ai-agent-tokens-ranking) Build it in Voltfin Studio: https://app.voltfincrypto.com/signup?next=%2F
