Network
SCP enables validators to agree on ledger updates. Transactions that are included in a closed ledger are final under Stellar’s protocol design.
Transaction safety guide
Security starts with verification.
Stellar has protocol-level safeguards, but safe use also depends on the token issuer, wallet, application and decisions you make.
No blockchain can guarantee every asset or transaction is safe. Stellar consensus helps validators agree on ledger updates. It does not certify that a token is legitimate, an issuer is solvent, a market is liquid or a website is genuine.
Three layers to understand
Asset issuer
Issuers may configure authorization, freeze and clawback controls for an asset. Review what powers exist and what they mean for holders.
Your wallet & actions
Protect private keys, verify destination details and review every transaction before signing. A secure network cannot protect a compromised key.
Before you trade or exchange
Check the full issuer keyDo not rely on a ticker or token name. Compare the issuer public key and asset code with official project documentation.
Confirm the networkMake sure the asset is on Stellar mainnet and that the wallet or service supports that exact asset.
Review the issuerLook for official documentation, redemption terms, reserve attestations where relevant and clear contact details.
Assess market qualityCheck liquidity, spread, trading volume, market depth and whether the asset can be redeemed or sold.
Protect credentialsNever share a secret key or recovery phrase. Avoid signing messages or transactions you do not understand.
Check destination detailsVerify the receiving address and any required memo. Consider a small test transfer when appropriate.
Issuer controls are not a guarantee
Stellar supports native asset controls such as authorization, freezing and clawback, depending on how an asset is configured. These can help issuers meet compliance or operational needs, but they can also affect holders. Read the issuer’s policies before acquiring an asset.
How a Stellar transaction works
A wallet prepares a transaction, the account signs it with its secret key, and the signed transaction is submitted to the network. Validators use SCP to agree on ledger updates. Fees and minimum-balance requirements are paid in XLM. Always review the transaction details that your wallet displays before signing.
