Safe (safe)

Multi-signature smart contract wallet. Supports programmable account abstraction and modular security.

Fact	Value
Category	Infrastructure and standards
Family	none
Namespace	`Safe` on ethereum, optimism, polygon, arc, base, arbitrum
Chains	ethereum, optimism, polygon, arc, base, arbitrum

What it offers

safeV141 is for Ethereum L1; safeL2V130 is the L2-optimized version (emits events for cheaper indexing)
operation: 0 = CALL (normal), 1 = DELEGATECALL (execute in Safe context)
signatures are sorted by owner address, packed as 65 bytes each (r, s, v)
Modular: supports Guards (pre/post checks), Modules (extend functionality), and Fallback handlers

On Ethereum, Safe is a namespace: its contracts need no import.

function main() {
  // Ethereum's safeL2V130, `0x3E5c63644E683549055b9Be8653de26E0B4CD36E`.
  require(Safe.SafeL2V130 != 0);
}
