Overview
Gasless USDC wallet. Self-custody. No native gas tokens.
Sigma9 is a self-custody USDC wallet. Send and bridge your USDC across chains completely gaslessly — you never hold a separate token just to pay network fees. You hold USDC, and USDC covers the fee. Cross-chain USDC bridging is powered by Circle CCTP, and your keys never leave your device. Full features and release notes: https://sigma9.app/extension
