Arbitrum Base Optimism Polygon Ethereum BNB Chain
This is one address that works on all major EVM chains — native coins are accepted on every listed chain, and USDC is accepted on Ethereum, Base, Arbitrum, Optimism, and Polygon. Double-check the network before sending; don't send non-EVM assets (e.g. Bitcoin or Solana) here.

Sponsor Claude Code Power Pack Pro

The public pack remains free. A suggested $12 tip unlocks three private bonus commands/agents — including a changelog generator, release checklist, and architecture reviewer. Send a supported native coin or USDC, then submit the chain and transaction hash through the Claim Pro access form. A GitHub Action verifies the payment and grants the GitHub account that opened the issue access automatically; no email or manual approval is required.
