PANews reported on December 12th that, according to The Block, Bitcoin rewards application Lolli now supports withdrawals on the Bitcoin Lightning Network after integrating with Spark. This move may help resolve complaints from some users since Lolli was acquired by Thesis in July. Spark is an open-source Bitcoin Layer 2 protocol developed by Lightspark, enabling instant, low-cost, self-custodial transactions of Bitcoin and Bitcoin-based assets, and is fully compatible with the Lightning Network. The two companies stated that Spark's software development kit (SDK) will provide "Lightning Network withdrawal support for Bitcoin rewards held on the Lolli platform."

Thesis' acquisition of Lolli has drawn criticism from some users. Shortly after the acquisition announcement, Lolli suspended all Bitcoin reward transfers and withdrawals to migrate its backend to Thesis' infrastructure, a move that angered some users. Furthermore, Thesis integrated its Ethereum Virtual Machine (EVM) compatible Mezo Bitcoin scaling and programmable layer into Lolli before allowing on-chain Bitcoin or Lightning Network transfers, further infuriating some users.
