# What an agent wallet listing shows

Every listing shows the same set of fields for each wallet or payment rail. Each fact links to the vendor's public docs or the protocol spec so you can check it yourself.

Every listing uses the same set of fields. This makes it easier to compare wallets and rails side by side. Each field is explained below.

The organization field shows who builds or runs the product. For open protocols it names the foundation or working group. For vendor products it names the company.

The status field shows live, beta or pilot, as the source describes the product. Open the source link to see the current stage.

The rail field shows the payment method: stablecoin, card, bank or mixed. Mixed means the product supports more than one.

The chains field lists the blockchains a product supports. The index can record Base, Ethereum, Solana, Polygon, Arbitrum, Optimism, Avalanche, Stellar, BNB Chain, Tempo, Kite and Bitcoin Lightning. A product may list one chain or many, or none.

The protocols field lists the open payment standards a product speaks. The index can record x402, MPP, ACP, AP2, L402, ATXP, A2A and UCP. Protocols that have their own listing link to their spec or site.

The per-call minimum shows the smallest payment the source states. Some sources set no minimum and leave it to the seller or the facilitator. Check the vendor docs for the real figure.

The spend caps field lists the limits the source describes: per transaction, per session, daily, weekly, monthly, per agent, and merchant or contract allowlist. None published means the source states no cap.

The human approval field shows whether a person must approve payments. Required means yes. Optional means you can choose. None means the source describes no approval step.

The KYC needed field shows whether the source describes an identity check: required, optional, none or varies.

The custody field shows who holds the signing keys. Self-custody means you hold them. Custodial means the provider holds them. Hybrid splits the work. Not applicable means the question does not fit that product, as with most protocols.

The MCP support field shows whether an MCP server exists. Official means the vendor publishes one. Community means someone else does. None means the index records none.

The fees field shows what the source states about charges. It is free text and can change. The licence field shows the licence the source states, such as Apache-2.0, MIT or Proprietary. The source field links the page used to check the row. Follow it to read the vendor's own words.

## Questions

### What if a field is empty on a listing?

It means the vendor's public docs do not state that fact. Empty does not mean the wallet lacks the feature. Check the source URL on the row.

### How often are listings updated?

The index plans a monthly check against each vendor's public docs or protocol spec. Read the source link on the listing for the current facts.

> **Check before you fund.** Features, fees and protocol support change. Follow the cited source on each row before you let an agent hold or spend money.
