The Sandbox LANDs are migrating to a brand new good contract
TL;DR
- A brand new model of the LAND smart-contract has been deployed; its tackle is 0x5CC5B05a8A13E3fBDB0BB9FcCd98D38e50F90c38
- The migration interface could be discovered right here: https://sandbox.game/en/me/migration/
- The earlier good 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.
- The difficulty didn’t permit transfers nor minting of latest LAND and no tokens have been compromised. Moreover, we’ve run thorough investigations on our different good contracts and none of them are in danger.
- We deployed a migration good contract to let everybody migrate their LAND to the brand new LAND contract; its tackle is 0x371f4c6fd305c6772Bc6224b795b0B46b6B6f8dB
- There isn’t a price concerned on the person’s facet. All migration fuel prices are solely lined by The Sandbox.
The Sandbox smart contracts have been extensively audited by two prime safety corporations, Certik and Solidified, and obtained high-security scores. These audits could be accessed publicly on our Github repository. The LAND good contract was initially audited by Certik on December 10th, 2019, and concerned three auditors via a two-week course of.
Nevertheless, a vulnerability was first found on December twenty fifth, 2021.
Upon studying of the vulnerability, we took fast 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 checks 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 substantiate the repair didn’t introduce new vulnerabilities.
- After consulting with fellow builders, all of us agreed the very best plan of action was to deploy the repair and allow customers emigrate all LAND tokens to the brand new good contract with none prices (gasless assist).
- The basis trigger has been investigated and a brand new good contract migration and interface has been developed.
- On January twenty eighth, we deployed the brand new mounted good contract; the tackle 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 solely lined by The Sandbox. No charges are incurred by our customers
After peer-reviewing a number of options, all of us agreed that the very best plan of action was to schedule a migration from the outdated LAND contract to the brand new one.
This migration isn’t pressured upon customers. They’ll do it at their very own tempo when they’re prepared.
We’re overlaying the fuel prices via the deployment of a gasless function 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:
When you want assist emigrate your LAND tokens, please contact us via
We plan to maintain the neighborhood up to date on the general progress of the migration. We’re conscious this can be a very distinctive scenario and are doing all the things we will to maintain the method as seamless and clear as attainable.
