The Sandbox LANDs are migrating to a brand new sensible contract
- A brand new model of the LAND smart-contract has been deployed; its deal with is 0x5CC5B05a8A13E3fBDB0BB9FcCd98D38e50F90c38
- The migration interface could be discovered right here: https://sandbox.game/en/me/migration/
- The earlier sensible contract contained a vulnerability that was first reported on December twenty fifth, 2021.
- The vulnerability has been mounted and the repair audited. It has not been exploited by any malicious person and has now been secured.

- There isn’t any value concerned on the person’s aspect. All migration fuel prices are totally lined by The Sandbox.
The Sandbox smart contracts had been extensively audited by two prime safety companies, Certik and Solidified, and obtained high-security scores. These audits could be accessed publicly on our Github repository. The LAND sensible contract was initially audited by Certik on December 10th, 2019, and concerned three auditors by means of a two-week course of.
Nonetheless, a vulnerability was first found on December twenty fifth, 2021.
Upon studying of the vulnerability, we took speedy motion to repair the difficulty, as the next timeline demonstrates:
- On Dec twenty fifth, a safety researcher referred to as Danel Hazlewood (@Alphasoups) notified us of the vulnerability.
- On Dec twenty fifth, we carried out inside exams and confirmed the reproducibility of the difficulty.
- Between December twenty fifth and thirtieth, we labored on a repair and submitted it for audit again by Certik security auditors to verify the repair didn’t introduce new vulnerabilities.
- After consulting with fellow builders, all of us agreed the perfect plan of action was to deploy the repair and allow customers emigrate all LAND tokens to the brand new sensible contract with none prices (gasless assist).
- The basis trigger has been investigated and a brand new sensible contract migration and interface has been developed.
- On January twenty eighth, we deployed the brand new mounted sensible contract; the deal with is 0x371f4c6fd305c6772Bc6224b795b0B46b6B6f8dB
- We additionally deployed further safety measures to make sure the security of all LAND whereas the migration is in progress
- On January twenty eighth, we launched our migration interface to let each LAND proprietor migrate their LAND tokens to the brand new contract. All of the fuel prices related are totally lined by The Sandbox. No charges are incurred by our customers
After peer-reviewing a number of options, all of us agreed that the perfect plan of action was to schedule a migration from the outdated LAND contract to the brand new one.
This migration shouldn’t be pressured upon customers. They’ll do it at their very own tempo when they’re prepared.
We’re overlaying the fuel prices by means of the deployment of a gasless characteristic for this migration.
So, don’t fear — this course of:
- Is free to all customers
- Has no time restrict
We launched the migration interface on January twenty eighth:
