Sovereign L1 · Solidity · Live
A live Solidity chain, running in the open.
Satsuma is a sovereign Layer-1 that runs Solidity smart contracts — live in production, Ethereum-compatible, with blocks that finalize in seconds. Every block is public and readable by anyone; writing to the chain is permissioned.
What Satsuma is
A real chain, not a demo. Solidity, not a subset.
Its own Layer-1 — sovereign, live, and fully transparent. It speaks Ethereum, runs the Solidity you'd expect at full fidelity, and keeps every byte of state in public view. The only thing it holds back is who's allowed to write.
Real Solidity
Contracts run with full EVM semantics — the same bytecode the ecosystem already speaks, no subset and no surprises.
Public by default
Every block, transaction, and contract call is readable by anyone. The chain hides nothing — the explorer is its front door.
Closed where it counts
Reading is open to all. Transacting and deploying is limited to approved accounts — the chain is sovereign, and stays that way.
Speaks Ethereum
A standard Ethereum JSON-RPC interface and an EIP-155 chain ID mean familiar wallets and explorers understand Satsuma out of the box.
