Yap Signer
Wallet risk notice
Last updated: September 20, 2026
Yap Signer is experimental software. It is a self-custodial Chrome extension for a Solana bot wallet. Read this before you create, restore, or fund a wallet.
You hold the keys
Yap Signer stores your 24-word recovery phrase in an AES-256-GCM vault on this device. Yap does not have a copy of your seed, password, or private key. This website cannot create, import, export, or reset a wallet. If you lose the phrase, forget the password, or wipe the browser profile, Yap cannot recover the funds.
Blockchain transactions are irreversible
Sends, swaps, and other Solana transactions cannot be undone once they confirm. Wrong addresses, spoofed recipients, failed quotes, and network congestion are your risk. Review every transaction in the popup before you sign.
Silent signing is optional and constrained
Silent mode stays off until you generate a one-time yap_pat_ platform access token and paste it into an allowlisted Yap site. Signer still inspects the fee payer, DEX program allowlist, and SOL-out cap. Token (SPL) value is not included in that cap. Do not arm silent mode unless you understand those limits.
Network and software risk
Balances, quotes, and broadcasts depend on RPC providers, Jupiter, DexScreener, CoinGecko, and the Solana network. Any of those can be slow, unavailable, or incorrect. Browser extensions can contain bugs. Use amounts you can afford to lose while the software is experimental.
Not a custodian
Yap Signer is not a bank, broker, or custodial exchange. It does not currently operate five custodial agent wallets, KMS/HSM custody, campaigns, wallet groups, warmers, or onramp. Those may appear later as a separate platform. They are not live in this product.
Your responsibility
You are responsible for securing this device, the vault password, and the 24-word phrase; for verifying URLs and recipients; and for complying with laws that apply to you. Nothing on yap-pay.xyz is financial, legal, or tax advice.
