Safe Blockspace.

{This is the future of smart contract networks}
DeFi users are not safe because blockchains treat theft as a valid action.

Safe blockspace uses math to programmatically classify theft and eliminate it, as all other unwanted actions have been.

Our mechanisms are non-custodial, and user rights are preserved by anchoring to Ethereum.

Use Firewall to protect users [or your] assets.

What is Safe Blockspace?

Our blockspace treat theft as an invalid action, as a means to eliminate smart contract exploits. There's three core components to our methodology.

Coming soon.

Today blockchains check a transaction for two items:
(1) the transaction is cryptographically signed by the user account it claims
(2) the user account has the money to pay transaction fees
‍‍

Malicious transactions meet this weak threshold, and therefore are accepted.
‍

Safe Blockspace adds (3) transaction doesn't steal user assets. Analysis of a transaction's intent before finalization.

Demand Better. Use Firewall.

Do you have assets onchain or use DeFi and smart contracts? Put your assets on safe blockspace for peace of mind.

Firewall is cultivating a grassroots effort. It is time for us to collectively demand Safe Blockspace.

About Us

Code is law, but the code is completely broken when it enables billions in users money be stolen by criminals. We've programmed our values, that theft is a crime and should not be accepted, into the system.

The outcome? The evolution of smart contract networks, where user safety is prioritized via radical advancement.
