Security

Trust starts in the code.

XSOIL's smart contracts are designed to grant only limited permissions, stay non-upgradeable and be verifiable on-chain. The presale contract holds no funds.

Pre-launch checklist

  • Independent security auditPending
  • Contract source verification on BscScanPlanned
  • Automated tests (90+ scenarios, 100% line coverage)Available
  • Trial deployment on BSC testnetAvailable

Core principles

The rules are not a promise; they are written into the contract's code. See for yourself the lines that enforce each principle.

Payments go straight to the treasury

The presale contract holds no funds. Each payment goes to a treasury address that can never be changed, in the same transaction.

Permission limits

What can the owner of the presale contract do, and what can never be done?

Can

  • Pause the sale for a limited time: at most 7 days at once and 14 days per stage in total; the stage clock stops while paused
  • Move the start date later (never earlier), before the sale begins
  • Switch a troubled stablecoin off, and back on
  • Start First Claim Activation once the sale is final

These powers are needed to run the sale. On mainnet, ownership sits with the project owner's wallet; pausing and switching a stablecoin off (the guardian role) rest with the same wallet. The owner can also end a pause early, replace the guardian, set the oldest BNB price data it accepts between 1 minute and 1 hour, return tokens other than XSL sent to the contract by mistake, and hand over ownership in two steps. Each action leaves an on-chain event that anyone can see.
