Safe Wallet overview
safe.kaia.io will sunset on August 31, 2026. Please use Safe Wallet for Kaia at app.safe.global to manage your accounts going forward. See Migrate to Safe Global if you already have a Safe.
Safe Wallet is Safe Global's official interface for Safe Smart Accounts. A Safe Smart Account is a smart contract wallet: instead of one private key controlling the funds, a set of signers must approve each transaction according to a confirmation threshold. Kaia Mainnet and Kairos Testnet are both available—connect an owner wallet, select the network, then create or open a Safe.
Key concepts
| Concept | What it means |
|---|---|
| Signers (owners) | The addresses allowed to propose and confirm transactions. Add, remove, or replace them at any time from Settings. |
| Threshold | How many signer confirmations a transaction needs before it can execute (for example 2 of 3). Keep it above 1. |
| Modules | Optional contracts that extend what the account can do—recovery, spending allowances, automation. A module can move funds without signer approval, so only enable ones you trust. |
| Guards | Optional contracts that check every transaction before and after execution, letting you enforce custom rules. |
| Safe Apps | Third-party apps embedded in the interface, such as the Transaction Builder and CSV Airdrop used in the guides below. |
For the full picture of how the account works on-chain, read How do Safe Smart Accounts work?.
Workspace
Workspace is Safe Global's environment for teams that run more than one Safe. It sits on top of the same smart accounts—it changes how a team coordinates, not how transactions execute or who holds keys.
- Unified dashboard — balances and pending transactions across every account in the space, in one view.
- Security Hub — signers, threshold, modules, guards, recovery options, and Safe version for each account, plus automated checks against its on-chain configuration.
- Shared address book — one set of labelled addresses for the whole team instead of a per-browser local list.
- Email login — teammates can sign in with an email one-time passcode or Google to view balances, follow pending transactions, and manage contacts without holding a key. Signing still requires an owner wallet.
That last point is useful for finance, compliance, and operations reviewers on Kaia who need visibility into a treasury Safe but should never be signers on it.
Safe Global documentation
Safe Wallet, the Safe Smart Account contracts, the Safe Core SDK, and the backend services are all built and maintained by Safe Global, and documented at docs.safe.global.
The Kaia docs cover what is specific to Kaia: supported networks, chain IDs, and walkthroughs of common tasks. For how Safe itself works—contract versions, module and guard behaviour, API schemas, SDK reference—refer to Safe Global's documentation, which the Safe team keeps current.

Kaia networks
| Network | Chain ID |
|---|---|
| Kaia Mainnet | 8217 |
| Kairos Testnet | 1001 |
Select the network from the chain switcher in Safe Wallet before creating or opening an account—a Safe deployed on Kairos is not visible while Mainnet is selected. When using the API Kit or other Safe SDK tooling, pass the matching chain ID and take the Transaction Service endpoint from Safe Global's supported networks rather than hardcoding one.
