# Fere AI vs PayBox

A source-linked comparison of MoonPay's PayBox and Fere AI: a payment vault your assistant can spend from, against an agent that decides what to do.

## Fere AI vs PayBox

PayBox is MoonPay's non-custodial payment vault. It connects to Claude and ChatGPT through a connector so an assistant can trade tokens, bridge assets, use DeFi apps and pay for online services, across Solana and EVM networks including Ethereum, Base, Arbitrum, Polygon and Hyperliquid. Keys are split with threshold cryptography inside secure enclaves so no single party holds a whole key, and nothing moves until you approve it with a passkey. Fere AI is a different layer of the same stack: it is the agent — it compiles a sentence into readable rules, dry-runs them, and runs them on a schedule under hard caps. PayBox gives an assistant hands. Fere gives it a job.

All claims about PayBox below come from their own site and documentation, verified 2026-09-03. Sources are linked at the bottom.

## Why traders choose Fere AI

- **It knows what to do, not just how to sign.** Fere researches, compiles a strategy from a sentence, backtests it and runs it. PayBox executes what an assistant has already decided.
- **It can act while you are asleep.** PayBox requires a passkey signature per transaction. A Fere strategy runs on a schedule under a cap, which is what unattended trading requires.
- **A staged path to live.** Monitor, dry run, paper, capped live — a rule proves itself before it spends anything.
- **Strategy-level limits.** Each strategy gets its own wallet and cap rather than sharing one vault balance.

## At a glance

| | PayBox | Fere AI |
| --- | --- | --- |
| What it is | A non-custodial payment vault that plugs into Claude and ChatGPT so an assistant can transact | An agent platform that turns a sentence into readable rules and runs them on a schedule under hard caps |
| Where the intelligence lives | In whatever assistant you connect. PayBox supplies the wallet and the approval flow | In Fere. It researches, compiles the strategy, backtests it and runs it |
| How you author a strategy | Not applicable — there is no strategy layer. You prompt an assistant per action | One sentence. Fere asks at most two clarifying questions, then compiles a spec you can read — numbered rules in plain English. |
| Approval model | A passkey signature per transaction. Nothing moves without it | You approve the strategy once, then it runs under a hard cap with a kill switch on every screen |
| Runs unattended | No. The passkey requirement means a human is in the loop for every transaction | Yes. Strategies run on a schedule with hard position caps and a kill switch on every screen, and each run is explained back to you in a sentence. |
| Who holds the keys | Non-custodial, split with threshold cryptography in secure enclaves so neither MoonPay nor the agent holds a full key | Non-custodial. Every strategy gets its own capped wallet, keys never leave an AWS Nitro TEE, and you can export to MetaMask or Phantom. |
| Where it executes | Solana plus Ethereum, Base, Arbitrum, Polygon, Hyperliquid, Tempo and Robinhood Chain | On-chain across Ethereum, Base, Arbitrum, Polygon, HyperEVM, Solana and BSC, with perps on Hyperliquid. Routed through Jupiter, 0x and LI.FI — best quote wins. |
| Beyond trading | Payment cards sit in the same vault and agents can pay for online services | Trading and research only. Fere does not pay for services or issue cards |
| Best for | Giving an assistant you already trust a safe way to spend, with a human approving every movement | Traders who can describe a strategy in a sentence and want it running unattended, with a staged path to live and a cap on what it can lose. |
| Scope | No strategy layer, no backtests, no scheduled execution — and by design, nothing happens while you are away from your passkey | Strategy automation end to end: authoring, dry run, paper, capped live execution and scheduling, on-chain across seven chains. |

## Where they differ

### The passkey is the whole comparison

PayBox requires you to sign each transaction with a passkey before it executes. For a payment vault holding cards and crypto that is exactly the right design — it is the reason an assistant with a spending limit is not terrifying. It also means PayBox cannot do the thing Fere exists for. A funding-rate strategy that has to act in the eight-hour window after a reset, at four in the morning, cannot wait for you to reach for your phone. Fere replaces per-transaction approval with per-strategy approval: you promote a strategy to live once, it runs inside a hard cap in its own wallet, and a kill switch sits on every screen. Different safety models for different jobs, and neither is the wrong answer to its own question.

### Two layers, not two products

A replacement framing would be dishonest here. PayBox is infrastructure — a wallet and an approval flow that any assistant can use. Fere is an application — the thing that decides what is worth doing. They meet at the same connector surface, because Fere also exposes an MCP server that Claude and ChatGPT connect to, but they meet from opposite directions. If you want ChatGPT to be able to buy something, PayBox. If you want something that researches markets, writes a strategy, tests it and runs it, that is a different kind of software.

### What Fere does not do

PayBox holds payment cards alongside crypto and lets an agent pay for online services. Fere has no equivalent and no plans described for one — it is a trading and research product, not a payments product. If the appeal is an assistant that can settle a subscription or buy something from a website, that is squarely PayBox's territory and not a gap Fere is trying to close.

## PayBox strengths

- **A genuinely careful key model.** Threshold cryptography inside secure enclaves, so neither MoonPay nor the agent ever holds a complete private key.
- **The passkey gate.** An agent that cannot move money without a human signature is the right default for a spending vault, and it is well executed.
- **MoonPay behind it.** Distribution, compliance experience and a payments business most crypto startups do not have.
- **Cards and crypto in one place.** Paying for online services and trading tokens from the same vault is something no trading agent offers.
- **Broad chain coverage.** Solana plus seven EVM networks including some, like Tempo and Robinhood Chain, that few competitors support.
- **Assistant-agnostic.** It gives whatever model you prefer the ability to transact, rather than tying you to one vendor's agent.

## Fere AI strengths

- **It is the agent.** Research, strategy compilation, backtesting and execution, rather than a wallet waiting for instructions.
- **Scheduled, unattended execution.** Strategies act on their own conditions at the moment those conditions occur.
- **The promotion ladder.** Monitor, dry run, paper, capped live — proof before money.
- **Per-strategy capped wallets.** Limits scoped to each rule rather than to a single shared vault.
- **A sourced strategy library.** Strategies compiled from traders and desks, credited and backtested, ready to run, fork or blend.

## What each one is built for

| What PayBox is built for | What Fere AI is built for |
| --- | --- |
| You want your assistant to be able to buy things, not just trade. | You want something that decides what to trade, not just something that can sign for it. |
| You want a human signature on every single movement of funds. | You need a strategy to act at 4am without waking you. |
| You want cards and crypto in the same vault. | You want backtests, a dry run and a paper stage before real money. |
| You need Tempo or Robinhood Chain. | You want per-strategy caps rather than one vault limit. |

## The short version

PayBox is a wallet for agents; Fere is an agent with a wallet. If you have an assistant you trust and you want it to be able to spend safely with your signature on every move, PayBox is well built and MoonPay is a serious operator. If what you actually want is the thing that works out what to do — researches, writes the strategy, tests it and runs it while you are asleep — that is a different layer, and a passkey prompt per transaction is precisely what stands in its way.
