What is Sig.Network?
Sig.Network is a universal layer that makes apps native across chains.
For the first time, you can deploy on your home chain and execute natively on every chain without restriction.
We enable smart contracts on different chains to interact directly, quickly, and securely by signing native messages with decentralized private keys.
Sig.Network removes fragementation from DeFi by letting smart contracts run natively across chains. No wrapping, no bridging, no liquidity balancing. Just chain abstraction.
