Payy Raises $6 Million to Build Private Stablecoin Payment Network

The startup bets zero-knowledge proofs can make USDC transfers confidential for enterprises.

Overview

  • Payy’s seed round, which closed in December 2025, was led by FirstMark Capital with Robot Ventures and DBA Crypto, bringing total funding to $8 million through a SAFE with token warrants.
  • The company is rolling out the Payy Network, an Ethereum Layer 2 that uses zero-knowledge proofs to hide the sender, receiver, and amount, with a testnet slated for next month that a dozen design partners are already testing and a mainnet planned for the summer.
  • Payy already offers a self-custodial wallet launched in January 2024 and a Visa card live since August 2025 that lets users spend USDC anywhere Visa is accepted.
  • The platform reports more than 100,000 users across 120 countries processing about $130 million in annualized volume, and it generates revenue from onramping fees, gas fees, and enterprise contracts.
  • CEO Sid Gandhi says public blockchains expose sensitive payment details, and rising efforts to enable private stablecoin transfers signal a competitive push to win institutional flows.
