Crypto exchange Gemini will begin accepting deposits in PAX Gold (PAXG), Amp (AMP) and Compound (COMP) with trading to start Sept. 15.

Gemini will offer US dollar trading pairs for PAXG, AMP, and COMP via its ActiveTrader platform and API connections. The exchange will also offer trading and custody support for 12 cryptos and custody for 13 cryptos.

Gemini co-founder Tyler Winklevoss tweeted the addition of PAXG, COMP and AMP shows the exchange’s commitment to DeFi.

Gemini said in its statement that the three assets “expand the range of our platform and further our mission to empower the individual through crypto.” The exchange said it worked closely with the New York State Department of Financial Services to gain approval to offer services for new assets.

Many major exchanges have started listing popular DeFi tokens. Coinbase, Houbi, Poloniex, OKEx and Binance have all listed different DeFi projects. 

Even as Gemini lists DeFi tokens, Winklevoss is still bullish on Bitcoin. He predicted Bitcoin would reach $500,000.
