A bitcoin ETF may be approved or rejected in the first few days of the new year.

Would-be bitcoin exchange-traded fund (ETF) issuer Hashdex changed its paperwork Friday, naming BitGo as its bitcoin custodian and changing the name of its Bitcoin Futures ETF to the Hashdex Bitcoin ETF as it – and other companies – continue to hope for an approval for the U.S.'s first spot bitcoin ETF early in the new year.

Hashdex has come to an agreement with crypto custodian BitGo to according to an amended S-1 filing, a rare outlier among the over a dozen applicants. The vast majority have signed agreements with crypto exchange Coinbase, while Fidelity intends to self-custody and VanEck tapped Gemini, another exchange.

The update comes a day after the SEC met with representatives from a number of other applicants.

Representatives from BlackRock, Valkyrie, Fidelity, Grayscale and Ark all spoke to officials with the SEC on Thursday, according to filings. The regulators set a Dec. 29 deadline for final amendments to the applications, Reuters reported.
