Contract Addresses

The published contract addresses behind Solid savings, the Safe multisigs that own them, and how permissions are enforced on-chain.

Updated September 11, 2026

Every Solid savings deposit sits in a smart contract you can inspect yourself. This page lists the production contracts behind Solid savings, the Safe multisigs that own them, and the operational addresses that interact with them.

Solid is non-custodial. When you deposit, you receive a share token (soUSD, soETH or soFUSE) that is held in your own wallet. Solid cannot move that token on your behalf.

Ownership and control

Every contract listed below is owned by a Safe multisig, one per chain. Changes to contract ownership or permissions require approval through these Safes.

Permissions are enforced on-chain, not by policy. Each contract in the system can only call the specific functions it has been granted, and that mapping is held in the RolesAuthority contracts listed with each asset below. Batch withdrawal processing requires multisig approval. Emergency pause controls exist so activity can be halted if an issue is detected.
