Gasless USDC wallet. Self-custody. No native gas tokens. Sigma9 is a self-custody stablecoin wallet. Send USDC and USDT completely gaslessly — you never hold a separate token just to pay network fees. The fee comes out of the same stablecoin you hold. Cross-chain bridging runs on Circle CCTP and LayerZero, and your keys never leave your device. Full features and release notes: https://sigma9.app/extension
