Substack Rolls Out Bitcoin Payments via OpenNode and Lightning Network
OpenNode and Substack will allow some crypto-focused subscribers to pay with both on-chain and Lightning bitcoin transactions.
Substack’s over 500,000 paying subscribers will now be able to pay using bitcoin through the Lightning Network, a layered payment network for Bitcoin.
- The announcement was made by OpenNode, a bitcoin payment processor that has integrated its API to allow both on-chain and Lightning payments on the Substack online publishing platform. To start, OpenNode and Substack are making the payment system available to a select group of crypto-focused publications.
- The Lightning Network is a layer 2 payment rail built on top of the Bitcoin blockchain that enables secure, private and near-instantaneous transactions at little to no cost.
- Transactions on the Lightning Network use real bitcoin but can process over 3,000,000 times more transactions per second.
- "Having this option will give writers more flexibility and freedom, and we look forward to doing more in crypto to meet writers' needs,” said Nick Inzucchi, product designer at Substack.
- "Our partnership will allow content creators across the Substack ecosystem to accept bitcoin payments, and retain earnings in bitcoin or convert to preferred currency. Writers and podcasters have flocked to Substack to regain creative and financial freedom, and bitcoin is a natural fit," said João Almeida, co-founder and CTO at OpenNode.

Pudgy Penguins: A New Blueprint for Tokenized Culture

Pudgy Penguins is building a multi-vertical consumer IP platform — combining phygital products, games, NFTs and PENGU to monetize culture at scale.
What to know:
Pudgy Penguins is emerging as one of the strongest NFT-native brands of this cycle, shifting from speculative “digital luxury goods” into a multi-vertical consumer IP platform. Its strategy is to acquire users through mainstream channels first; toys, retail partnerships and viral media, then onboard them into Web3 through games, NFTs and the PENGU token.
The ecosystem now spans phygital products (> $13M retail sales and >1M units sold), games and experiences (Pudgy Party surpassed 500k downloads in two weeks), and a widely distributed token (airdropped to 6M+ wallets). While the market is currently pricing Pudgy at a premium relative to traditional IP peers, sustained success depends on execution across retail expansion, gaming adoption and deeper token utility.
