Users of Coinbase’s mobile crypto wallet can now automatically get alerts about on-chain activity through messaging service Notifi. Perpetuals exchange GMX is the first customer of the service, according to a press release. Customers of the Arbitrum and Avalanche-based platforms will receive notifications about pending liquidations and governance updates, and can also design their own automated message notifications. The service marks an expansion of Coinbase’s XMTP-based messaging channel. The XMTP protocol has allowed Coinbase wallet users to send messages between each other since July last year. Notifi is also using the XMTP protocol, the press release said.
