AI Agents Bring New Rules for Crypto Wallets

AI agents are entering crypto through wallets, exchanges, payment apps, trading systems, and portfolio tools. Once an agent receives signing authority, it can prepare transactions, rebalance assets, pay invoices, use smart contracts, and move across on-chain apps at software speed.

This creates a new product category around controlled autonomy. The user keeps ownership of the funds, while software handles repetitive execution under rules set in advance.

BeInCrypto spoke with Fernando Lillo Aranda, CMO at Zoomex; Federico Variola, CEO of Phemex; and Adrian Wall, Managing Director of the Digital Sovereignty Alliance, about early use cases, transaction approval, user limits, on-chain activity, and new risks once agents gain access to funds.

Payments Come First

Adrian Wall sees payments as the earliest major use case for AI agents, since payment mandates can be narrowed by amount, recipient, asset type, and timing.

“Payments are the earliest use case because the parameters are well-defined and the mandate is constrained,” Wall said.

Stablecoins make cross-border payments a natural area for agent activity, especially in markets where bank transfers remain slow, expensive, or difficult to reconcile.

“Cross-border payments are especially compelling given the friction in legacy banking and the demonstrated efficiency of stablecoins,” Wall said.

Trading and portfolio management are also ready from a technical view, but Wall placed more emphasis on governance than execution.

“Trading and portfolio management are technically mature enough today,” he said, adding the harder challenge is “whether authorization frameworks and loss limits are sophisticated enough to keep an agent’s mandate from drifting beyond what the user intended.”

Identity may take longer, although Wall said decentralized identifiers and agent-assisted verification could reduce repeat authentication across fragmented digital services.

“The combination of decentralized identifiers and agent-driven verification is promising because it could reduce the burden on users who currently authenticate themselves repeatedly across fragmented systems,” Wall said.

Wallet Approvals Need Transaction-by-Transaction Controls

Wallets were built around human review, while agents may prepare many actions across apps, contracts, and venues. Wall said wallet design now has to connect product choices with policy expectations.

“The approval question is where policy and product design must converge, and it is where the industry has the most work left to do,” Wall said.

A strong approval model gives agents limited authority for routine actions while requiring human review for withdrawals, leverage, new contracts, and large swaps.

“What we need is a tiered authorization model where the level of scrutiny matches the potential impact of the transaction,” Wall said.

This approach can separate monitoring, trade preparation, execution, and fund movement. A user may permit an agent to watch positions and draft trades, while reserving withdrawals and new contract access for manual approval.

Fund Access Should Grow in Stages

Fernando Lillo Aranda said AI agents can improve automation, but users should give capital access gradually.

“AI agents can unlock automation, but capital access should always be progressive,” Lillo Aranda said.

He described the process as a gradual path from observation to assistance and execution. In practice, the agent first monitors and recommends, then prepares actions for approval, later receives limited execution rights, and eventually handles a larger mandate after reliable performance.

Capital controls come first. Lillo Aranda said users should “cap maximum allocation, daily loss, position size, and withdrawal amounts.”

Permission controls come next. Users should “separate permissions for monitoring, trading, rebalancing, and fund movement,” he said.

Time limits also reduce exposure from old approvals. Lillo Aranda said agent access should “require periodic re-authorization instead of permanent access.”

Market boundaries can prevent agents from entering assets, venues, or leverage levels outside the user’s comfort zone. Users should “restrict assets, leverage, venues, and volatility conditions where the agent can operate,” he said.

Human override remains the final guardrail. Lillo Aranda pointed to “instant pause, approval thresholds, alerts, and rollback mechanisms” as essential user controls.

Wall also put spending caps at the center of user protection. He said users should start low and raise limits only after observing how the agent behaves across market conditions and instruction types.

“The first and most fundamental limit is a spending cap, set low at the outset and adjusted upward only as the user develops confidence in how the agent behaves across market conditions and instruction types,” Wall said.

Above a preset threshold, human approval should remain in place even after an agent builds a good track record.

“The asymmetry between an interrupted transaction and an unauthorized one almost always favors interruption,” Wall said.

On-Chain Volume Needs Economic Purpose

Federico Variola said AI agents can create meaningful on-chain activity because blockchain apps let software move across many products and strategies.

“Yes, AI agents can create meaningful on-chain volume, especially because on-chain environments offer composability and flexibility across different strategies,” Variola said.

Those strategies may include spot trading, perpetual futures, lending, borrowing, and future products linked to assets beyond native crypto.

“This could include spot, perpetual futures, lending, borrowing, and eventually products outside native crypto assets as well,” Variola said.

Variola drew a line between activity with economic use and recursive trading among agents.

“A lot of on-chain activity today is still driven by human sentiment and greed,” he said.

Durable agent volume, in his view, depends on activity tied to productive use across on-chain ecosystems.

“Agents need to create or support real economic value,” Variola said.

Wall expects much of today’s agent activity to begin inside controlled app environments before moving on-chain as products and rules mature.

“Agents on public blockchains can access far more counterparties, assets, and protocols than any walled garden allows,” Wall said.

He expects trading and arbitrage to appear first, followed by treasury and settlement activity.

“The impact will show up in volume before it shows up in value, first driven by high frequency trading and arbitrage, and later by treasury management and institutional settlement,” Wall said.

Agent Risk Moves at Software Speed

Once agents gain signing rights, familiar crypto risks become faster and harder to contain. Wall highlighted mandate drift, exploit propagation, perception manipulation, and correlated market behavior.

“When software can trade, sign, and interact with smart contracts on a user’s behalf, four familiar risks become newly dangerous,” Wall said.

The first problem is mandate drift, where an agent moves beyond the user’s original instruction set.

“Agents can exceed their mandate,” Wall said.

The second problem is speed. An exploit can move through many connected wallets or contracts before a user sees the damage.

“Exploits can propagate at machine speed across every wallet an agent touches before any human notices,” Wall said.

The third problem comes from manipulated inputs. Attackers may feed an agent fake prompts, poisoned data, or malicious contract information, causing harmful actions even when the user keeps custody of the key.

Market behavior creates another concern when many agents rely on similar data sources, strategies, and models. In those conditions, many systems can sell, rebalance, or withdraw liquidity at the same time.

Wall said markets can destabilize when agents “respond rationally to the same inputs at the same time.”

Final Thoughts

AI agents will reach crypto wallets through constrained tasks first: payments, rebalancing, subscriptions, trading, and portfolio support. These use cases can operate under defined limits, measured permissions, and regular user review.

The strongest wallet model will center on controlled autonomy: scoped permissions, session keys, spending caps, renewal windows, whitelisted counterparties, approval thresholds, alerts, and emergency pause controls.

On-chain volume can grow if agents handle payments, settlement, treasury, and asset operations tied to economic use. Recursive trading among agents may increase transaction counts, but lasting value comes from activity tied to people, businesses, assets, and services.
