MoonPay PayBox Gives X Users Wallet Access On Solana And EVM
By Scarlett · Chief of Staff · 19 Oct 2026
MoonPay said on Oct. 7, 2026 that PayBox users can connect their X account to get a Solana and EVM wallet tied to their handle. The feature lets anyone send crypto to that handle through Grok.
MoonPay said on the seventh of October 2026 that users of its PayBox feature receive a Solana and EVM wallet tied directly to their X handle once they connect the account.
What Users Receive
Holders download the PayBox app and link their X account. The connection creates a wallet address that anyone can reach by sending crypto to the X handle through Grok. The setup works in the mobile app or through the web app settings page on the PayBox site.
Users no longer share long wallet strings. They give out the X handle instead. This change removes one step for the sender and keeps the receiver in control of the destination address.
Wallet Type And Control
PayBox operates as a non-custodial wallet built for AI agents. Each wallet is generated through MoonX MPC. The private key stays inside a secure enclave and never leaves that environment.
Above-threshold or sensitive actions stop until the user approves them with a passkey. Every operation logs as an audit event. At any moment the user can revoke an agent client so it loses all access.
Sending Process
Once the X account is tied to the wallet, a sender opens Grok and enters the handle. The crypto travels to the linked Solana or EVM address without further steps from the receiver. The receiver sees the incoming transaction in the PayBox app.
The feature went live on Oct. 7, 2026. Both MoonPay and PayBox posted confirmation on X the same day. The posts listed the exact steps for setup and the supported chains.
Security Steps Built In
The MPC model keeps key material off user devices during creation. Passkey gates add a second check before large moves. Audit logs give a full record of activity. Revocation removes any connected agent without moving funds or changing the underlying wallet.
These controls stay active for every account that connects an X handle. The non-custodial design means MoonPay does not hold the keys at any point.
Practical Use
A holder who wants incoming payments can post the X handle publicly. Senders who know the handle route funds through Grok without asking for a new address each time. The wallet remains under the same passkey and revocation rules even after many transactions.
The product keeps the same approval flow whether the sender uses Grok on mobile or desktop. No extra approvals are required from the receiver beyond the initial account connection.
Summary Of Access
PayBox users gain a wallet address mapped to their X identity. They keep full control through passkeys and revocation options. Senders gain a simple handle-based route on Solana and EVM chains. The Oct. 7, 2026 launch made these steps available to anyone who downloads the app and connects an X account.
