SafePal's browser extension 2.42.0 adds Tron energy rental, bStocks trading and biometric unlock

What is new in 2.42.0

SafePal said on 10 November 2026 that version 2.42.0 of its browser extension wallet is live. It lists three additions: energy rental for Tron transfers, so you pay less in fees; support for trading bStocks; and biometric unlock for faster access to the wallet. The release graphic shows the extension for Chrome and Edge, and SafePal asks users to update to the latest version.

The post is short and does not give prices, a token list or device requirements, so the rest of this story explains each feature from SafePal's own documentation and is careful about what has not been published.

Tron energy rental, explained

On Tron, transactions consume two resources. Bandwidth covers basic activity, and every wallet gets 600 free Bandwidth a day. Energy is needed for smart contract actions, and sending USDT counts as one because USDT is a token contract. A plain TRX transfer does not need Energy. If your wallet has no Energy when you send USDT, the network burns TRX from your balance instead.

SafePal's help center explains how renting Energy from SafePal works in its mobile app, where the feature already existed. In its example, a USDT transfer without Energy costs about 13.85 TRX, while renting the Energy costs about 5.85 TRX, a saving of about 8 TRX. The rented Energy arrives within five minutes, refills during the lease and is taken back when the lease ends. A brand new Tron wallet must first receive at least 1 TRX, and sending USDT to an address that has never held it needs about twice the Energy. Those figures are SafePal's app example; it has not published separate prices for the extension.

bStocks and biometric unlock

bStock trading support brings tokenized stocks into the extension. SafePal's hardware wallet firmware released on 12 October already added bstock token trading for the S1, S1 Pro and X1, so the browser wallet now matches. SafePal's post does not say which bStock tokens are supported or where they can be traded.

Biometric unlock lets you open the extension faster than typing your password, according to SafePal. The post does not say which browsers, operating systems or devices support it.

Our take

Energy rental is the change most people will notice, because USDT on Tron is one of the most common ways to move stablecoins and every transfer without Energy burns TRX. If you send USDT on Tron more than occasionally, compare the rental price with the TRX the wallet would otherwise burn before each send. Treat bStocks as tokenized stock products with their own issuer terms, not as shares, and check whether they are offered where you live. Biometric unlock is a convenience: it does not replace your recovery phrase backup or your extension password.
