TRX, the native token of the Tron network, surged over 140% on cryptocurrency exchange FTX, from 12 cents to 29 cents after Tron founder Justin Sun agreed to move Tron-based assets from FTX to external wallets.

“We are pleased to announce that we have reached an agreement with Tron to establish a special facility to allow holders of tron (TRX), bittorrent (BTT), just (JST), sun (SUN) and huobi token (HT) to swap assets from FTX 1:1 to external wallets,” FTX tweeted Thursday.

On Wednesday, TRX momentarily jumped 4,000% to a 24-hour high of $2.50 on speculation that Tron-based assets would be redeemed on a 1:1 basis by Sun, but fell back to near zero levels later in the day.
