Sig.Network is a cross-chain messaging and execution layer that enables smart contracts deployed on one blockchain to execute native transactions on other blockchains without bridging or wrapping assets. The core architecture uses a decentralized MPC validator set to produce threshold signatures, converting cross-contract calls into standard signed transactions that are submitted directly to destination chain mempools, supporting Ethereum, Solana, Polkadot, and Bitcoin. The primary users are DeFi application developers who want to access liquidity and assets across ecosystems from a single deployment, without migrating contracts or adopting new tooling. Sig.Network launched its Ethereum mainnet in March 2025 and Solana mainnet in August 2025, with Polkadot and Bitcoin integrations on the roadmap.

Sigil is a European crypto hedge fund founded in 2019 that offers two distinct strategies to qualified investors: Sigil Core, a high-risk directional strategy targeting dynamic crypto assets, and Sigil Stable, a market-neutral strategy designed to capture market inefficiencies with low volatility. The fund is co-founded by Pavel and Fiskantes, and the team maintains significant skin in the game by allocating at least one-third of AUM to internal capital. Sigil targets institutional and qualified private investors seeking managed exposure to the crypto asset class without conducting their own research. The fund provides investors with dedicated dashboards offering 24/7 access to portfolio data, performance metrics, and history, and is registered with a financial regulator (GFSC visible in footer). Notable institutional investors include WOOD and Company and Miton Group.
