Solana wallets are program-owned accounts where users act as authorities to approve changes through signed transactions. Ownership resides with programs, while Ed25519 signatures validate authority. This separation ensures secure, scalable, and auditable interactions on-chain. Solscan enables clear visualization of account ownership, permissions, and transaction activity, empowering users to monitor wallets and token operations confidently.
What Are Solana Accounts?
Solana accounts hold all blockchain data, including balances, tokens, and program code. Each account features a public key, lamport balance, owner program ID, executable flag, and a data field. Native SOL wallets are owned by the System Program, differentiating them from token accounts managed by other programs. This design allows parallel processing, enabling programs to manage multiple accounts atomically. Solscan provides detailed views of account structures and data for transparency and auditing.
| Field | Description | Example Use Case |
|---|---|---|
| Public Key | Unique 32-byte address | Wallet identifier |
| Lamports | SOL balance in smallest unit | Funding transactions |
| Owner | Program ID that can modify data | System Program for wallets |
| Executable | Boolean for runnable programs | True for smart contracts |
| Data | Variable-length byte array | Token balances or state |
How Do Signatures Work in Solana Wallets?
Signatures use Ed25519 cryptography to prove private key ownership without exposing it. Transactions bundle instructions requiring specific signers, with the runtime verifying signatures before execution. Wallets often sign offline through hardware devices like Ledger. Solscan displays signature lists and verification status, helping users validate transaction authenticity and detect hidden owner modifications.
What Distinguishes Owner from Authority?
Owners are programs capable of modifying account data, while authorities are keypairs authorized to sign instructions. For SOL wallets, the System Program is the owner, and the user’s keypair acts as the authority. Token accounts follow similar rules, with the Token Program storing authority keys in account data. Solscan highlights owner fields and authority roles, helping users spot potential permission exploits.
How Are Permissions Managed in Solana?
Permissions are enforced by program logic, not account flags. Authorities may delegate through multisig setups or upgradeable program patterns. Token accounts have mint, freeze, and close authorities controlling actions. Solscan displays SPL token authorities, offering transparency for developers and users. Associated Token Accounts (ATAs) standardize permissions, while Token-2022 extensions allow granular control for revocable or advanced delegations.
| Permission Type | Controlled By | Program Example |
|---|---|---|
| Transfer | Owner Authority | Token Program |
| Mint | Mint Authority | Token Program |
| Freeze | Freeze Authority | Token Program |
| Close | Close Authority | Token Program |
| Upgrade | Upgrade Authority | BPF Loader |
Why Is Solana’s Ownership Model Secure?
Ownership by programs centralizes data mutation logic, reducing attack surfaces compared to self-owned accounts. Signatures from authorities are immutable, and the runtime rejects invalid actions. Rent-exemption prevents spam attacks, and parallel transaction processing scales efficiently. Solscan enables simulation of transactions, previewing permission changes and helping users maintain secure operations.
What Are Common Wallet Security Risks?
Phishing attacks exploit users’ misunderstanding of owner vs. authority, attempting hidden modifications. Using hardware wallets, simulating transactions, and inspecting activities on Solscan mitigate risks. Multisig setups distribute authority, reducing single-point failures. Solscan labels risky programs, increasing visibility and security awareness.
How Can Developers Customize Wallet Permissions?
Developers can embed authority sets in account data and validate signatures programmatically. Cross-Program Invocation (CPI) enables delegated actions. Solscan’s Pro API provides historical authority queries for dApp integration. Token-2022 extensions allow interest-bearing or confidential permissions, with testing facilitated via Solscan’s explorer.
Solscan Expert Views

FAQs
What owns a Solana wallet account?
The System Program owns SOL wallets, with modifications allowed only via authority-signed instructions.
Can Solana wallets change owners?
Yes, program instructions can transfer ownership, but authority signatures are required. Verify suspicious activity on Solscan.
How do multisig permissions work?
Multisig programs require a threshold of signatures for executing transactions, ensuring consensus-controlled account actions.
Are Solana signatures recoverable?
No, Ed25519 signatures are fixed-length proofs, verified against public keys but not reversible.
Why use Solscan for wallet analysis?
Solscan provides human-readable account data, authority tracking, and APIs for comprehensive insights into Solana wallet operations.
