To check a Stellar DeFi protocol before connecting your wallet, verify the site and intended network, identify the exact contract and function, inspect what the wallet asks you to authorize, and simulate the call when a reliable tool supports it. These steps help you understand a proposed interaction; they do not prove that the protocol, its code, or its administrators are safe.
How do I check a Stellar DeFi protocol before connecting my wallet?
Start with the destination and the transaction you expect—not the protocol’s name or a reassuring badge. A wallet connection or signature can expose different permissions, so understand what the site is asking before proceeding.
- Verify the site. Reach the project through a source you already trust, such as its established documentation, rather than an unsolicited message or advertisement. A Stellar Lab network selector helps you choose a network, but it does not authenticate a project website or prove that a contract belongs to that project.
- Confirm the network. Check that the site, wallet, and any simulation tool refer to the network you intend to use. Do not assume the network is correct because the protocol name looks familiar.
- Find the exact contract and function. Compare the contract ID and function with project documentation and trustworthy independent references. A familiar name alone does not authenticate a contract ID.
- Understand the proposed action. Before approving a connection or signing anything, determine what the site wants to do and whether that matches the action you initiated. Stop if you cannot tell.
What should I check before signing a Soroban transaction?
Read the wallet prompt as a description of an operation you are being asked to authorize, not as a routine confirmation. Stellar documentation distinguishes authorization—deciding which operations should be allowed—from authentication, which concerns proving identity or control.
- Check the function and arguments shown, including any addresses and assets involved.
- Ask whether those details fit the action you intended on the selected network.
- Do not sign a prompt that is opaque, unexpected, or materially different from your intended action until you understand it.
Stellar’s signing guide distinguishes signing a transaction from signing an authorization entry. It describes transaction signing as intended for accounts that fully trust the transaction and know how to thoroughly verify its authenticity and security. The guide recommends enforcement-mode simulation to validate signatures and execution before submission.

Can I simulate a Stellar smart-contract transaction before submitting it?
Yes. Stellar’s RPC reference describes simulateTransaction for simulating a single invokeHostFunction transaction. It can return effective transaction data, required authorizations, and a minimal resource fee. The reference, last updated August 19, 2025, lists authorization modes including enforce, record, and record_allow_nonroot.
Simulation is useful for previewing how a proposed invocation may execute and what it may require. It is not a security audit, a guarantee of a later result, or proof that a protocol is safe.

Using Stellar Lab’s Contract Explorer
Stellar Lab’s Contract Explorer guidance describes a flow in which you select a network, enter a contract and function, provide parameters, and simulate the call. Use it to examine the proposed invocation before deciding whether to submit it.
The guidance distinguishes reads from writes: a read operation does not change contract state, so it need not be submitted just to inspect its result. Submit a write operation only when you intend to change network data.
Why a successful simulation is not a guarantee
Simulation runs against a temporary ledger snapshot. Ledger state can change before you submit, making the simulated footprint stale and the eventual result different. Review the wallet prompt even after a successful simulation, and do not treat simulation as evidence that the contract’s code, governance, administrators, or economics are trustworthy.

An audit label is not the same as a verified report for the contract you are about to use. If a project claims to have been audited, look for the report itself and check:
Rank #4
- Who performed the review and which contracts and versions it covered.
- Whether the deployed contract and network match the report’s stated scope.
- Whether the report records findings and remediation, rather than relying only on a badge or summary.
- Whether the project has administrative or upgrade powers, and what evidence explains how those powers are governed.
An audit can inform due diligence; it does not guarantee safety. The checks described here do not establish the security of any particular Stellar DeFi protocol. Each project and deployment requires separate verification.
