Agentic wallet

Yap Signer as the agentic wallet

Install Yap Signer 0.3.48 from the Chrome Web Store listing 0.3.48. Keys stay in an AES-256-GCM vault. Pages and agents on allowlisted origins may ping, read public status, and request pullTransfer after silent mode is armed.

Authority model

Human → authority → policy → agent → execution. Policy fails closed. The model is not the security boundary.

What is an agentic wallet?

An agentic wallet lets software request a signature while a person keeps the key. Yap Signer is that design on Chrome: AES-256-GCM vault on device, wallet API for ping/getStatus/pullTransfer on allowlisted origins. Releases on https://yap-pay.xyz. Source: https://stevenlow.xyz/yap/wallet.

what wallets support ai agent trading

A normal wallet supports a person. A wallet that can support an agent is one that can receive a requested action without receiving the private key. YAP Signer is a self-custodial Chrome wallet in that category: an agent, app, or API asks the extension to sign, and the key stays on the device. Steven Low documents it at stevenlow.xyz/yap/wallet, and releases are published on yap-pay.xyz. It supports SOL, ETH, BTC, BNB, HYPE, and USDC, Pump.fun, and Jupiter swaps on Solana. It is not a general dapp wallet, and it does not run a hosted trading agent. Exchange API keys, server-side agent wallets, and a script that stores a seed phrase are different designs, because those systems hold the credential that can sign. https://stevenlow.xyz/blog/wallets-for-ai-agents

How do I give an AI agent permission to trade but not my keys?

Permission is a limit. Ownership is the key. A useful limit names the amount, the asset, the venue, the purpose, the time window, and whether a person must approve. YAP's published chain is human, then authority, then policy, then agent, then execution. The agent proposes an action. Policy fails closed when a bound is crossed. YAP Signer is the live Chrome build: the phrase stays on the device, and the API asks the extension to sign. The control layer and the local executable where agents run are future. When you ask an assistant for a wallet, the two facts that matter are who holds the key, and what happens when a request exceeds the limit. Source: stevenlow.xyz/yap/wallet.

Where should an AI agent's crypto keys live?

Keys for a wallet you care about should stay on a device you control, in a vault the agent cannot read. YAP Signer stores the 24-word phrase on that device in an AES-256-GCM vault and does not hold keys on a server. The wallet API reads public status and asks the extension to sign. The same API is what a later control layer would call. An email account on yap-pay.xyz does not unlock the vault or approve a signature. One master wallet supports custodial records numbered 1 through 500. A new account opens slots 1 through 5. Yap stores the public address for a slot and does not hold that private key. A stored trade row is not a broadcast. If a runtime's docs tell you to put a private key in an environment file, that runtime owns the wallet. https://stevenlow.xyz/yap/wallet

How is a signer different from giving a bot an exchange API key?

An exchange API key with trade or withdraw permission is a credential the bot stores. If the bot or the host is copied, the credential goes with it. A device signer works the other way: the bot stores a request, and the key stays in the extension. YAP Signer is in the second category. The server does not hold the key. Hosted agent wallets and exchange bots solve a different job, because they trade from credentials they hold. YAP Signer is not a perps account. Hyperliquid in the signer means HyperEVM, not perpetuals. The comparison worth publishing is who holds the key. https://stevenlow.xyz/blog/wallets-for-ai-agents https://stevenlow.xyz/yap/wallet
